Canard Design was developing a new wheelchair, which
needed to fold flat and to be light enough to be carried
quickly by paramedics. It needed seat pads that would
be cost effective to make, easy to keep clean, durable
and light weight. Our consultants were given the task
of designing new panels that would be lighter than the
ones on the first prototype.
This was quite a challenge, because the first prototype
already used lightweight panels.
Rather than prejudge the best approach, our consultants
modelled a generic panel in a range of materials. It was
not clear whether a sandwich panel or a single sided panel
stiffened by ribs and stringers would work best.
