Mastering fluid flow to enhance user experience

Ice cream and blood are two things you probably don’t want to think about simultaneously. But both are full of organic proteins and fats and behave differently from a fluid like water when they’re pumped through tubes. Innovators sometimes think about these similarities when creating, for example, a novel ice cream dispenser or device that filters out platelets from donor blood .

How a substance flows is a vitally important consideration for many products, from foods to skincare to medical devices to household paints. Development teams need to keep in mind a wide range of flow behaviors (for example, flow through nozzles, non-Newtonian flow, and foaming) to hit the sweet spot: a positive user experience that makes a product stand out in a crowded market. This means thinking about the science of how liquids and gases behave (fluid dynamics), as well as how the product responds to user interaction.

Look at how the squeezable plastic ketchup bottle differs from the glass bottles that were standard before 1983. The new design completely changed the user experience – no more digging down into the bottle with a knife to get the ketchup flowing again. Things became even easier for ketchup lovers with the debut of the upside-down squeezable bottle – no more awkwardly storing ‘regular’ bottles upside down in the fridge.

Or think about how the experience of washing your hands changed after the arrival of the liquid soap dispenser. Instead of having to share the same bar of soap with others, people can now wash “without the soapy mess”, as Robert R Taylor, who introduced SoftSoap liquid soap, put it, and can take only as much soap as they need.

While the flow of some liquids is analogous to water, whose behavior is well understood, other substances behave in much more complicated ways, requiring in-depth analysis work to understand when designing new products. For example, the air bubbles in ice cream make it behave as a liquid foam. Ice cream’s flow will change depending on how you’re dispensing it: Push it at high pressure through a narrow channel or nozzle, and the air bubbles will be compressed, allowing more ice cream to flow through the nozzle at once. When the ice cream is returned to normal pressure, the air bubbles re-expand, and the ice cream returns to its original size. Because of this complex and variable behavior, designing a product to dispense ice cream relies on hands-on experiments… which can mean going through gallons of ice cream before you can create a design that works as intended. Only by conducting these experiments to understand ice cream’s behavior can you build the mathematical model required to effectively develop a high-performance machine.

While it’s a shame to use gallons of ice cream in the quest for a better product, it’s not an environmental disaster. But shipping water-based products around the world does contribute to fossil fuel consumption and climate change. Removing water from laundry detergent helps cut shipping emissions by reducing bulk and making shipping more efficient. But it also dramatically changes how detergent flows and gets used by consumers. For example, measuring out 10 ml more detergent than recommended likely wouldn’t have an impact if you’re using a product that’s mostly water. But being off by 10 ml when detergent is concentrated could make a big difference for your laundry. So, it’s vital to ensure that dispensing is accurate, which requires an understanding of flow.

There are so many flow behaviors that can affect a product’s design. For example, should a container for insecticide include a mechanism to avoid skin contact and spillage? How could a medical device for freezing tumors be redesigned to eliminate vapor locks without the use of heavy and bulky high-pressure gas cylinders? Is there a way to dispense foaming hand soap in a decorative pattern for a premium experience?

Getting the design right for a flowing substance can differentiate between a product that fails and one that creates an experience that shifts category norms and delivers breakthrough consumer delight.

Impediments to tobacco harm reduction in LMICs:

The ENDS adoption journey

BY NICKI SUTTON, BEN KELSEY & GEORGE BOSTOCK
Whitepaper_Impediments-to-tobacco-harm-reduction-in-LMICs_cover

“We were able to define an ENDS Adoption Journey which outlines seven steps a smoker must take to substitute combustible tobacco products with ENDS.”

Tobacco consumption has, for decades, represented a global pandemic. Over 1.3 billion people, or 16% of the world’s population, use tobacco in one of its many forms, grouped into combustible or smokeless types. 80% of these users reside in low and middle-income countries (LMICs) where tobacco use contributes to increased morbidity and mortality directly and indirectly, via poverty.

The Foundation for a Smoke-Free World (FSFW) has a goal to advance progress in smoking cessation and tobacco harm reduction (THR) with a particular focus on LMICs. To better understand some of the challenges faced in these markets, FSFW commissioned us to identify the barriers or impediments to adoption of electronic nicotine delivery systems (ENDS) in LMIC countries.

The chance to create the world’s first prescription electronic cigarette

What should we make of the Medicines and Healthcare products Regulatory Agency (MHRA) updating its guidance for licensing e-cigarettes as medicinal products?

The updated ‘Guidance for licensing electronic cigarettes and other inhaled nicotine-containing products as medicines’ (published on October 29, 2021) sets out with extra detail the steps needed to license e-cigarettes as medicinal products, meeting the quality, safety, and efficacy criteria demanded of other medicinal products.

Any medicinally licensed e-cigarette could potentially be prescribed to people who want to quit or cut down on smoking, meaning England would be the first country in the world to prescribe medicinally licensed e-cigarettes to help reduce smoking rates.

But hang on, it was already possible for e-cigarette manufacturers to submit their products for this regulatory approval process, so what’s going on?

Call to action

Dr June Raine, Chief Executive of the MHRA, said in a press release, “The MHRA will continue to support companies in the development of safe and effective e-cigarette products, to encourage the licensing of e-cigarette products as medicines in order to support patient-centred care and access.”

The MHRA’s announcement is a re-emphasis of its support of this product category’s role in smoking cessation and a call to action for the e-cigarette market. The update gives us cause to reflect that a commercially viable product hasn’t yet taken up this opportunity. Why?

The large companies in the tobacco space aren’t familiar with designing under the constraints of a medicinal product or going through regulatory approval for medicines. Smaller players are concerned about the funding required to go down the medicinal route.

There’s a perception that the medicinal pathway is complicated and costly. There’s no denying that the bar for regulatory approval as a medicinal product is set imposingly high as it seeks to ensure safety, quality, and efficacy for users.

A CE mark is required to sell a medicinal product in the European Union, indicating compliance with ISO 13485. This standard defines the quality management systems used to control the product’s design, manufacture, and post-market surveillance. Compared to consumer products, this places much greater emphasis on risk assessment and mitigation throughout the product lifecycle, along with robust documentation to demonstrate regulatory compliance.

If the MHRA’s announcement reflects its frustration at the lack of progress to meet the perceived demand for a prescription-based device, can manufacturers expect an easier route to a license as a result?

The requirements of ISO 13485 will still need to be met in full, but perhaps the MHRA will expedite engagement with the applicants, which could certainly help the process. The announcement is significant in reinforcing the prevailing UK public health policy that e-cigarettes can play a key role in smoking cessation, providing an ‘open door’ for a forward-thinking player to advance and elevate the product category.

Continuum of product stewardship

The tobacco harm reduction market has been on a journey of increasing commitment to product stewardship, partly driven by increasing regulation, for example, Tobacco Products Directive (TPD) and Premarket Tobacco Product Application (PMTA), and the increasing sophistication of the major players.

CDP serves clients in consumer and regulated healthcare markets, so we’re familiar with the challenges of operating in these different regulatory frameworks. For those already invested in product stewardship, perhaps the leap to a medicinal product won’t be as challenging as they think.

While the MHRA’s announcement may not be ‘news’, it does perhaps signal a reappraisal of the opportunity to create the world’s first prescription e-cigarette.

What next for events in the world of COVID-19?

The impact of the pandemic has dramatically shaken up the world of conferences and events. Ana Romero, Digital Marketer and Events Coordinator at Cambridge Design Partnership, looks back over a tumultuous year and asks, “what next”?

Here we are, almost exactly a year ago. This is Pharmapack, in Paris. The two-day event was attended by 5,500 delegates and more than 400 exhibitors, and just look at the optimism on our faces! We don’t know it yet, but this is the last physical event we’ll attend before the pandemic descends, forcing us into our spare rooms and at the mercy of Teams, Zoom, and an emerging world of digital-only events.

Welcome to chaos

A month later, in March 2020, the events world was in chaos and turmoil. I was busy contacting the organizers of each event we were planning to attend, checking their websites for updates, following the news and, arranging refunds for cancelled conferences.

Many conference organizers simply announced that they would be cancelling their 2020 offering and would be back in 2021. But others tried to offer a virtual experience. The idea of going online came as a relief to us here at CDP – as we were just as keen as before to share our expertise, to network with our peers, and meet tomorrow’s clients.

However, the transition to digital has been challenging, especially for event organizers dramatically adapting their business model and event delivery in a matter of weeks.

Forget the plan; it’s time to adapt.

So what have we learned? The most immediate learning for us at CDP has been that a good virtual conference is made by enabling the sort of interactions which make a physical conference so valuable. Can you get talking with someone who is visiting the event, develop them into a contact and then, hopefully, a client?

The first virtual conference we attended didn’t work at all. We couldn’t network with other companies, to reach the people we wanted or to strike up any sort of rapport with other attendees. A low bar had been set.

However, in only a few months, I’ve seen many improvements in the different platforms used and some real successes so far. Several virtual conferences we’ve attended during the pandemic have offered far better ways to connect and market to delegates. For example, some platforms allowed us to see and filter the delegate list (by name, role, and company name) and to request a one-to-one meeting with that person. In addition, the ability to watch presentations on demand made it easier to book a video conference during a session slot and later go and watch what we missed, something that wouldn’t have been possible in a real-life event.

Virtual conferences have crystallized how important it is to have your material in a digital and interactive format. We’ve learned to have just enough collateral in the digital booth to initiate a conversation. In a virtual exhibition, it’s easier to visit a virtual booth and fill your virtual goodie bag with all of the marketing collateral with just a click. This also has the risk of someone (including competitors) downloading your collateral and leaving the booth without saying a word. While this wouldn’t normally happen in a physical event it’s not hugely problematic: our materials can be seen by anyone.

One downside is that international events may not be particularly international: if an event is taking place on UK time and you want people from around the globe to virtually attend, you’ll find it’s tricky to enable conversations between members that are located in the US or Asia, due to the time differences. We’ve noticed this effect in the events we’ve taken part in.

We don’t expect face-to-face events to return properly in 2021. While many events companies are talking a confident game that plans for face-to-face before the year is out, most are adding other options to their virtual offerings. Think here of webinars, roundtables, and other additions that tend to suggest the new world is becoming “baked in”.

The post-COVID future

With all this virtual activity and conferencing ability we might ask, will the world ever go back to face-to-face conferences?

My feeling is that the leap to digital is a permanent one, but that physical conferences are far from finished. There are some significant downsides to virtual interaction that cannot easily be overcome. The first is the nature of the experience itself. If you travel to a conference and attend for two or three days, you are committed. You have spent time and money to get there, and as a result, you give it all your attention and energy, which makes the whole process more immersive. By contrast, a digital conference that you attend from your office or your home will struggle to capture your focus in the same way. You are so much more likely to be reading emails, on the phone, or being interrupted by your kids.

The very fact that it is so effortless to attend a digital conference can make it a less valued experience. If you “bump into” a delegate virtually, by messaging them through the conference’s contact system, it is far easier for them to ignore you. However, if you meet them at a real-life event, your chances of striking up a fruitful conversation are far stronger. Perhaps this is a good thing, forcing us to be on top of our game, offering nothing but compelling content and conversations. Although the process of tracking down attendees at a virtual conference is now quite slick, there’s nothing quite like meeting someone face-to-face and all of the non-verbal communication that goes into those meetings. It’s much harder to entertain clients and to build up goodwill online.

A crucial part of why we here at CDP value the opportunities offered by real-life conferences is that they give us the chance to develop and share our thought leadership. The events themselves are part of our learning, and giving presentations or taking part in discussions help to raise our profile in our key markets. The fact that a virtual conference presentation will often remain online for several months extends our reach significantly. We can also access information which shows who has been watching and, where it’s relevant and data protection allows, we can reach out to them afterwards to continue the conversation. This is a definite advantage of virtual events.

But when it comes to displaying our physical work, we want to show off what we create and allow booth visitors to interact with a connected inhaler, an innovative food packaging concept or any other product development. It’s hard to replicate the tactile experience of a real-life display of products that can be picked up and examined and where a visitor can ask questions of the development team.

All of this suggests that we’re headed for a future of hybrid physical and digital events. There will be real-life events, but some digital tools, such as one-to-one video meetings, digital roundtables, and others currently being explored will stay. Physical and remote attendees will be offered far more connectivity and interaction with other attendees than ever before.

In the meantime, as we press through the pandemic and emerge on the other side, it’s crucial to be creative and make use of the technology that allows us to connect virtually. It’s fair to say that virtual events are not yet providing the full benefits of a real-life gathering. But we are where we are and it’s in all our interests to work with digital alternatives so that we can keep doing business, one way or another. Whether it’s physical or digital, I’ll see you there.
