CAD designs for assisted knee pads

As an inventor, I am seeking to develop a set of CAD designs for assisted knee pads. These designs will be used for product visualization purposes and will focus on 3D modelling. It is essential that the CAD designs feature both basic and detailed elements that accurately showcase my vision of how the pads should look. If successful, these designs could then be used to develop a prototype and for manufacturing purposes. The market I would be targeting is tradespeople, as from personal experience a lot of these people suffer from prolonged injuries due to kneeling and rolling on their knees to get up. I have researched products similar to the idea I have, however they are for sporting activities or to assist with injuries. It is a similar product to these I would be looking for just with some added protection to the knee area. I have added some pictures to further portray my idea.
