Quantitative injection moulding design guidelines covering polymer wall thickness and shrinkage, 0.40T-0.60T rib root ratios, volcano boss relief, and SPI/VDI 3400/Mold-Tech draft lookup tables.
Engineering guide to kiosk enclosures covering 14-16 ga sheet metal bend reliefs, PEM hardware, derated CFM thermal chimneys, NEMA 4X/IK10 sealing, ADA 308 reach, and 3D printing vs CNC machining.
Set entrance and success criteria for a hardware project using Stage-Gate International's five stages and NASA's review structure, without guessing a prototype quota.
Sequence one industrial design portfolio case study through brief constraints, sketch alternatives, a foam model and an assembly detail with traceable evidence.
Practice mechanical design engineer handover skills with a worked clearance stack, a sourced draft check, and the decisions a manufacturer needs before tooling.
Learn what a manufacturing specification includes and audit your student hardware handoff package with a worked manifest that catches revision and material gaps.
Budget a physical prototype learning test with a blank worksheet for samples, setup, people and repeat work. Separate cash costs, borrowed resources and unknowns.
From iterative CAD modeling and physical prototyping methods to tooling economics and DFM verification. Who publishes this journal is described on About NUSPB.
Plan a physical prototype test with a copyable worksheet for the build, task, setup, assistance, observations and next iteration. Includes a fictional desk example.
A fictional desk critique turns each comment into a question and the next check. Scores, ratings, and a winning concept stay blank.
A Pugh sheet marks each concept against a baseline. A weighted sheet multiplies a rating by a weight. This hardware exercise leaves both tables blank until a check exists.
Write a one-page product design brief before any user interviews. A desk-accessory starter shows how to tag observed notes, sources, assumptions and unknowns.
A design brief states the problem. A design specification lists testable criteria. This worksheet maps one desk-accessory need to a check, and leaves unmeasured limits as OPEN.
Compare 3D printing and CNC machining for prototypes by quantity, material, tolerance, geometry and iteration speed, with a stage-by-stage decision flow and enclosure examples.
