The system problem

01

Customization cannot depend on manually rebuilding CAD every time.

Wheelchair and scooter frames vary. A fixed clamp cannot serve that variation, while manual CAD editing makes every new fit expensive and dependent on the original designer.

I reduced the product interface to two user-supplied diameters. Those values enter a design table, drive a parameterized SolidWorks assembly, and produce a complete set of printable files.

The implementation boundary matters: the web and export code was AI-assisted. This case demonstrates product definition, CAD parameterization, workflow orchestration, and validation. It is not presented as proof of unaided Python authorship.

Architecture

Two inputs, one controlled rebuild, nineteen files.

Workflow

04

The user sees measurements and outputs, not the CAD internals.

FIG 03Measurement is treated as a product step. The interface supports calipers, a circumference conversion, and fractional-inch conversion.

FIG 04The smallest useful interface is two explicit diameters with units and bounded ranges.

Decisions

05

Guardrails are part of the product.

01

Two inputs instead of an open CAD editor

The end user needs a fit path, not access to the model’s entire parameter space.

02

Explicit range validation instead of “universal” generation

Wheelchair inputs are constrained to 18–32 mm and scooter inputs to 12.7–33.02 mm in the recovered workflow.

03

One packaged output instead of loose files

Each generated configuration is named, grouped, and zipped so the assembly remains coherent.

Print path

06

The workflow includes fabrication preparation.
