Engineering status

This page documents a concept design assembled from commercially available parts. Parts, pricing, performance, medical claims, enclosure tolerances, and injection architecture are proposed design targets. Final selections require supplier confirmation, prototyping, clinical validation, regulatory review, and design-for-manufacture testing before any production or medical-use claim is made.

Display envelope: a 1.45" round panel is Ø36.8 mm, but the planar model still budgets31×31 mm. Reconcile in CAD.2. Planar budget is over-allocated in the design model (see the sealed-core fit check); thelayout above stacks modules to fit.3. The eMMC sits under the board in the 0.6 mm battery clearance; package height andswelling allowance need verification.4. Medication pod is a separate sealed lug module; actuator, needle path and drug stabilityare unspecified research items.5.

Core fit margin

Layered core minimum: 161 mm² planar margin; modeled stack margin: 3.6 mm. CAD interference and tolerances remain required.

Power balance

Battery life and load balance are unverified until measured on a populated prototype.

Runtime model

Idealized energy-only estimate: 149 hours; radio bursts, conversion losses, temperature, battery aging, and safety reserve are not modeled.
