Industrial design review · Production guide
Storyboard a folding mechanism using three source CAD poses
Use the 25°, 45° and 65° source poses from the same parametric arm. Describe the pivot and annotate the arm angle relative to its source axis.
Input and decision
Use the SCAD arm-angle parameter as the source of the three frames. The base footprint is fixed at 142 by 96 mm; the arm is 128 mm long. Pivot 01 is an original presentation model. Material and mechanical approval require their own evidence.
Set up the comparison
Keep the pivot and camera fixed. Put the angle directly beneath each frame so a reviewer can distinguish a new position from a new perspective.
Make the comparison
Overlay the three poses with B01 aligned. The H01 pivot should remain in the same place while the arm rotates around it.
Worked record
The downloadable worksheet includes the records below and a blank row for your own project.
| Pose | Arm angle | Pivot reference | Unverified clearance | Reviewer |
|---|---|---|---|---|
| Low | 25 degrees | H01 | Untested | Engineering |
| Mid | 45 degrees | H01 | Untested | Engineering |
| Raised | 65 degrees | H01 | Untested | Engineering |
Check the result
Review the sequence for visual continuity. Test stops, finger safety, contact and mechanical interference in engineering CAD or on a prototype separately.
Hand off the revision
Deliver 25°, 45° and 65° in angular order with the SCAD source. Give engineering the unresolved contact list.
Review question
Can the three model poses establish the physical end stops?
The source has a 142 × 96 mm base and a 128 mm arm. The angles show a parameter sweep. Mechanical stops, contact and safe clearance still require engineering evidence.
