The Backstory

(from an interview of the Philips design team by Tanya Weaver from DEVELOP3D Magazine)

According to a Unity Global Study in 2014, men shave fewer than three times per week and only 9 per cent of men aged 18-24 shave every day.

Philips, which has many products within the male grooming category, noticed this trend too from its own sales. Although its beard trimming business was growing, it was selling less electric shavers.

As a result, in 2012 it started carrying out some internal research and working with focus groups in co-create sessions. “The male grooming category was due a disruption and we discovered that young guys hardly seem to want to use the same tools as their fathers did,” says Jens Andersson, design lead, male grooming at Philips.

“They’re not interested in electric shavers and instead opt for manual blades. This was an opportunity to design a product that would appeal to them.”
Multiple tools
They discovered that, although young men are shaving less, they’re actually changing styles more.

They may grow stubble on the weekend or indeed for a week before they shave. For this they were using multiple tools because a beard trimmer wouldn’t give a clean shave and a manual blade wouldn’t get through a week’s worth of beard.

So Andersson and his team set about exploring the possibility of a dual sided blade hybrid tool that was somewhere between an electric shaver and a manual blade. In these early stages they were exploring with sketches before moving into CAD.

Enter solidThinking® Evolve

Jens Andersson joined Philips 3.5 years ago and is a Design Lead at Philips Design. Jens is primarily responsible for the industrial design of products in the Male Grooming department.

This consists of shavers, beard trimmers, hair clippers, and more. In his role, Jens also works with other teams to design products including health care, personal health, and CT scanners. Jens is not only responsible for working with marketing and engineering to bring new products to market, but is also, together with the team, tasked with coordinating the brand’s portfolio management and 5-year plan.

A little over three years ago the team at Philips set out to find a new piece of software for their team that would work better than their current tools. The goal was to find one tool that could be used by all members of the team. This would help to create consistency, easy file transfer/handoff with design peers and engineering, and would increase overall team speed and efficiency.

Jens was selected for the solidThinking® Evolve pilot program and set out on a 1-week training course with the tool. Shortly after the course and some one-on-one training, Jens utilized Evolve on a live project.

solidThinking Evolve In The Design Process

Since learning solidThinking® Evolve, Jens has used Evolve on a number of projects, including three that have already gone to market, as well as multiple strategic projects that Philips is currently exploring in health care, male grooming, and personal health.

When asked about Evolve, Jens noted,

“As a designer, we are always under pressure to deliver results in a short period of time, Evolve has been a big advantage for me over other conceptual CAD packages. Its construction history features allow me to adapt my models for both business or technical reasons while development is ongoing verses starting from scratch.”

Jens also commented on the speed of the tool,

“With Evolve I can quickly react and tweak the design while keeping the original design intent. It allows me to work on many quick iterations to visualize different options and solutions. This is very key to our development at Philips as it allows all stakeholders to be involved in the feedback process. I build so much faster in Evolve than what I have ever done in other software before.”

Using solidThinking™ Evolve to design the Philips OneBlade

Picking up again with the interview of the Philips design team by Tanya Weaver from DEVELOP3D Magazine

Philips OneBlade design sketches Rapid 3D South African agents for solidTHINKING EVOLVEIn these early stages they were exploring with sketches before moving into CAD, the main tool being SolidThinking Evolve, and using that data to produce basic prototypes.

Some of these prototypes then went back to the focus groups to gauge feedback. “We really try to connect as often as we can with users in the early stage of product development to really learn a lot in the beginning so that we de-risk our development process when we start to invest more and more,” says Andersson.

In the meantime, in Philips’ innovation lab, the engineers had been working on a new linear cutting technology. Being a technology driven company, it needs to constantly explore new technologies and innovation to remain a leader in its field.

What they had developed was a single blade with a cutting mechanism that can move 200 times per second to achieve a close shave but not quite ‘baby smooth’.

Philips didn’t yet know how to position this new technology within its male grooming portfolio and did some work with users in different parts of the world to discover how they could bring it to the consumer in a meaningful way. The ‘eureka’ moment came when they thought of bringing this technology to the clean-shaving averse young man.

Having found their niche, the engineers took this new cutting element and fashioned it onto an existing handle to see if it could do the job. It could but it needed the head to pivot to help tackle the more difficult areas of the face.

“While at first it cut from one side of the cutter, we made it cut from both. So you can go back and forth and it will also follow the contours of your face to cut as close as possible,” describes Andersson.
Breakthrough technology
Now, with a blade technology that could shave, trim as well as edge, the challenge was to create a product that could communicate that to users.

The aim was for it to look like nothing else on the market – reminiscent of an electric shaver but with something exciting injected into it.

“When launching a new technology it’s very difficult to communicate what it is or does. And typically with shavers you don’t have a lot of time to explain – people just look at the product and draw their own first conclusions,” explains Arjen Benders, Philips’ design director.

With the challenge set to develop a product that would appeal particularly to younger men, the design team drew inspiration from various mood boards that they had put together. “It’s more about fashion trainers and headphones than luxury cars and expensive watches,” says Andersson.

They also wanted to bring contrast into the product. This would be achieved through contrasting colours but also grip patterns on the handle that could help convey that, like a manual blade, this product could be used in the shower.
Design cues
Another design cue that they took from manual blades was to emphasise the eject function with a large button, which will release the blade when it needs replacing (about every four months).

“We thought that this would help emphasise the fact that this product is something different from a traditional electric shaver because it has a replaceable element or a consumable,” says Andersson.

With sketches developing on the design side, the engineering team meanwhile were working on the technology components and electronics in SolidThinking®, which would then be passed over to the designers.

According to Andersson, many CAD models were built to explore the various expressions of the product and consequences of different choices. As is often the case in most development projects, there is an element of give and take between engineers and designers.

“Certain engineering solutions might lead to a size increase, for instance, and then this would need to be visualised with a model really quickly. Equally, design may push it too far and the engineers can’t make it. There’s a lot of back and forth but we tried to keep a constant flow of updated models so that there is always the latest volume model at hand in the studio,” comments Andersson.

One key element that they worked particularly hard to achieve with the engineering team was a thinner handle than that of a traditional electric shaver so as to increase visibility around the cutting element.

“For blade users who are, for instance, creating edges to maintain a certain style, they don’t want to have half their face covered by a big, chunky product. They want visibility to be able to see what you’re doing and a product that is as thin as a blade is more appealing,” explains Andersson.

Designing the Philips OneBlade Rapid 3D South African agents for solidTHINKING EVOLVETo test their various concepts, the CAD data is used to produce prototypes and in the early stages these are just basic volume models. These are then used internally to judge the look, size and ergonomics and are also brought to weekly meetings with the marketing team, which take place throughout the development process, for their input and feedback.

At regular intervals, they will also check in with users to see whether they are on the right track. If changes need to be made, the design and engineering team will refine the CAD model and then more prototypes will be produced.

This is an ongoing cycle with many loops. As Andersson says, “It is always a moving target in a product development like this – so we constantly need to shift direction a little bit with the different input we get.”

Further into the development process as the design becomes more refined, more sophisticated prototypes are made. These are done at the model shop within Philips’ development site, which is an hour and a half drive from the design office in the Amsterdam headquarters, and contains a number of 3D printing machines and processes. Often, a CAD file is sent to a machine and a 3D print is couriered the next day or the day after.

One 3D printing tool that the team found very beneficial was the 3D Systems ProJet 600 colour printer. “You just define the colour you want in CAD and then the printer prints like an inkjet printer but in 3D. It’s really helpful because you get an impression of where the split lines are and the contrasts in the product. That definitely helps a lot,” says Andersson.

Benders adds, “Most of the time we want products to appear smaller than they are because technology is bigger than what we would like. Having colour breaks up the volume to make the product appear smaller and now we can already see this effect in the 3D prints. And also, we can experiment with different colours to try make a case for doing it a certain way because some colours work better than others.”
Ready for launch
After months of honing and refining, the One Blade was ready to go onto the market.

Based on positive feedback from users who tested the pre-production prototypes, Philips started to ramp up production ahead of launch into retail stores in the select markets of Germany, France, US and UK.

And it’s certainly exceeding Andersson’s expectations, “It has sold twice as much as we predicted it to do. We are just selling as many as we can produce at the moment and that is why we have not approached more markets yet.”

What’s Next?

Jens has become extremely productive in solidThinking® Evolve, he has already used it on multiple products that are on the market including the Philips OneBlade, the Philips Health Watch, and the Philips Bodygroom series 1000.

Jens noted,

“Working in the collaboration-driven environment of Philips design demands tools that I can depend on to help deliver great products to market quickly. Evolve in particular is a powerful software for enabling designs in our fast-paced development environment. It helps me gain speed not only in bringing design concepts to life, but also in driving fast iteration loops with the development team.

I especially appreciate the construction history as consumer product development can be a moving target as consumer insight and feasibility is constantly effecting the design. Evolve’s features allow us to intuitively adjust the design throughout the process, generating options and visualizing solutions quickly to keep the design intent intact.

Evolve is striking the perfect balance between a conceptual design software and a rigid engineering package. It has the power of construction history and surface control but also allowing conceptual modeling without being too inflexible.”

Jens is planning to continue his usage of Evolve while also encouraging and teaching colleagues at Philips Design to learn the tool.
