Global innovations begin with a prototype
A prototype like “Walkassist” (as it was called in the beginning) is not nearly enough to satisfy customers on the market.
It began with wanting or having to install all the electronics inside the shoe. The circuit boards, battery for powering the electronics, cable connections and sensors were installed in the shoe sole and almost completely filled it. For this to happen, each shoe had to undergo hours of processing, which of course would have involved an enormous costs for the shoe industry if this installation type had become necessary for the market-ready shoe.
The development had to be completely turned on its head
Our engineers decided internally that the system had to be located in an external casing in order to prevent cable breaks and damage caused by the user’s body weight. This was only made possible because we have always worked consistently on miniaturising the electronics in parallel to these efforts.
The main advantage of this adjustment of bringing the electronics to outside of the shoe is that you, as a customer, can now purchase many different shoes. A pair of InnoMake attachments could then be removed from one pair of shoes and attached to another pair as required. We rose to this technical challenge in just one year.
We subsequently concentrated on the fine-tuning, as well as the very elaborate technical documentation and testing, which are essential for the declaration of conformity for a Class 1 medical device. The therefore necessary selection of components and battery also took a long time because only elements that comply with current medical standards according to relevant EU regulations may be used.
