Did children contribute to workshop inventions?

How many workshop inventions began with ideas from the children helping there?

That cannot be established here. Family involvement is considered likely, and personal experience illustrates how practical skills could pass between generations.

How many invention ideas came from children cannot be established from these stories. Family participation is nevertheless considered plausible, supported here by a personal recollection of practical work. Clarke helped his father and grandfather when young and credits that experience with skills he still uses. Mechanical car maintenance and woodworking are the examples given. The recollection explains how workshop knowledge can pass between generations, without identifying a child's contribution to any particular wartime invention.
