CAD work, shape studies, prototypes, structural differences, and the things that did not work. Not a news feed — a record of how the design got where it is.
RYF-001 / shapes maketh aim — 01
A shape decides an allocation, not a grip
Where the design of RYF-001 begins. What a mouse shape decides is not how you hold it, but an allocation: which movements of the hand are held still, and which are left free.

Why I started from the fingertip hold
Can stable aim exist in the grip with the least support? Why RYF-001 chose the fingertip hold, and the stabilising work that falls on the muscles as the price of its freedom.

Making it wider — inverting the rule
Holding prototypes of different widths side by side showed that narrowness was stiffening the muscles and taking freedom away. Why RYF-001, a fingertip mouse, was deliberately made wider.

Three freedoms left open — waist, flank angle, front
Sharply flared sides, and recessed clicks. What two rejected ideas made clear about where the design stands: it optimises an allocation; it does not prescribe a right answer.

What the prototypes found — board angle and sensor height
A design that was right in CAD was wrong in actual use. Revising a board angle that let the cable touch the mouse pad, and a sensor that was not mounted at the right height.

30 g without added reinforcement
The first internal structure, with no ribs, flexed the moment force went in. How rib placement and separate click plates gave the housing its own rigidity, without adding a reinforcing part.
