How to develop a novel wearable product?

Download to read offline

This presentation talks about the importance of understanding stakeholders requirements before starting the development of a novel wearable technology and uses examples from across the sporting sector to illustrate this.

The presentation also explains the use of a toolkit/workshop approach which allows us to visualise the impact of design decisions on size, cost, battery life, wireless range...so that trade offs can be understood and the right decisions made before budget & time is invested in development.

I’m not saying you shouldn’t be ambitious, but you should think through what would be the MVP that would be successful for you.

  27. 27. 27 March 2015 S3908-P-651 v1.027Commercially Confidential I’d like to introduce a toolkit that we have developed at CC that enables us to explore and understand the options for a connected device design. In a day workshop with our clients we use the toolkit to very quickly visualise the impact of decisions, and explore trade-offs so that you can understand the realities of the design direction before committing significant time & budget to development It lets us explore possible size, cost, range, battery life… It is a sketchpad for engineers!
  28. 28. 27 March 2015 S3908-P-651 v1.028Commercially Confidential I’m going to illustrate how you can use the toolkit using a very simple connected device concept…

  31. 31. 27 March 2015 S3908-P-651 v1.031Commercially Confidential If you go to an industrial designer this is what you might get… If you spend some time with an industrial designer they will talk with you to understand what it is you’re trying to create and pretty soon they’ll start drawing on a pad or the whiteboard. This is a really effective process – there’s communication in both directions. It’s easy to see the sketches and understand what the product might look like. The sketch provides a means of communicating that encourages exploration and questioning. If there’s something you don’t like you can ask….what happens if I change this…. So what happens when you need to design electronics, communications and advanced maths…?
  32. 32. 27 March 2015 S3908-P-651 v1.032Commercially Confidential How do we make a better sketch pad for everything else?
  33. 33. 27 March 2015 S3908-P-651 v1.033Commercially Confidential So whilst you were describing your concept, and the industrial designer was sketching, the engineer was thinking through the key components for the design in their head. That’s something that all engineers will do as soon as you start describing a problem to them, in fact it’s hard to get engineers not to do that! We can use the toolkit to bring this alive for our clients…to make it visual…
  34. 34. 27 March 2015 S3908-P-651 v1.034Commercially Confidential First let’s consider….What do I need inside my connected product? You’ll need…  A sensor to detect the activity  A radio to communicate with the rest of the world, and most radios these days come with spare processing capability that can be used to give the device some intelligence  As the user will probably want some simple feedback like whether it’s on or whether the battery is low we’ll add in an LED  The radio is going to need an antenna to work well  The algorithm will be the bit that uses the processing capability to convert the sensor data into activity information that the user can understand  And finally it will need to get power, so let’s add a battery
  35. 35. 27 March 2015 S3908-P-651 v1.035Commercially Confidential Choose parts Copy reference designs Test How big will it be? 2 cm Within seconds the toolkit will create an image to show the size of the PCB You can see that the size is dominated by the ground plane of the antenna. This is the ‘keep out’ zone that allows the antenna to function as intended antenna antenna ground plane
  36. 36. 27 March 2015 S3908-P-651 v1.036Commercially Confidential How can I make it smaller? Choose antenna Reduce ground plane Rapid prototype PCB Test Iterate Finalise 2 cm We can look at investing more effort in RF engineering to create a more compact antenna design. Before spending development time & budget doing this, let’s use the toolkit to visualise the impact this could have… …the toolkit includes a compact antenna design, so, within seconds, we can see an approximation of the impact and have an informed decision about whether this is worth the extra development cost or not.
  37. 37. 27 March 2015 S3908-P-651 v1.037Commercially Confidential We can do the same for power…
  38. 38. 27 March 2015 S3908-P-651 v1.038Commercially Confidential So how long will it last? LED Processing of sensor data: The algorithm
  39. 39. 27 March 2015 S3908-P-651 v1.039Commercially Confidential That’s not great – how can we improve the battery life?  Add a button  Assume more software effort so the algorithm requires less processing resource
  40. 40. 27 March 2015 S3908-P-651 v1.040Commercially Confidential How much will it cost? Conceptual BoM DetailedBoM  Sensor  Radio  LED  Antenna  Algorithm  Battery The toolkit links to on-line 3rd party catalogues for low volume components allowing us to quickly see the approx cost. And after the workshop we can talk to manufacturing partners to understand potential costs in high volume.
  41. 41. 27 March 2015 S3908-P-651 v1.041Commercially Confidential Use the sketchpad for engineers to explore and understand the trade offs in the design Pick your direction GO! GO! GO!
  42. 42. 27 March 2015 S3908-P-651 v1.042Commercially Confidential This is our ‘sketchpad’ for engineers! Similar to an industrial designers sketchpad it isn’t intended to be highly accurate, but rather to enable informed decisions and the evolution of the concept that will come from being able to visualise the trade offs and design options. We use the toolkit in a workshop style project with our clients to enable the right decisions to be made before starting work on the development.
