Meeting with the apprentices of the CFAI of Châlon-sur-Saône

With the prospect of a partnership with the CFAI-21-71, I was today presenting my bike to a group of young apprentices in alternation training. I was asking for their help with the machining of aluminum tubes that support solar panels. As a matter of fact, I had machined aluminum parts for sliding the lateral solar panels to reduce the width of the trailer. But my hand tools do not allow to obtain parts with precise and regular ribs, which leads to hinder or prevent its good fonvtionnement

The process of technical creation of solar bike

Throughout this project of creating a technical object, I was able to realize how complex the process of creation is, because indeed:

  • Many parameters are considered (of the Order of the physics;
  • Some parameters are closely correlated (while others are independent);
  • Some parameters are a personal choice or a preconceived idea, others are simply physical laws (NB: Sometimes it is not easier to lift an obstacle linked to a preconceived idea than another one linked to a physical law).

It is not a linear, but cyclical or rather spiral approach. We go through phases of information retrieval, design, research of the right material. Then come the phases of construction and experimentation. When we do not achieve the expected result, we return to the phases of research, design, construction and again experimentation. Sometimes, after several cycles, we achieve the intended goal, and we are happy! When you do not succeed, you are less… We are then led to question certain starting choices, some parameters. And then the cycle starts again…
