Part orientation.
Stable section ID: S05-CON-012-SECTION-26 · 37 content blocks
- approach direction.
- alignment.
- capture.
- temporary retention.
- final locking.
- tool access.
- hand access.
- robot access.
- visual verification.
- error prevention.
- assembly sequence.
- disassembly sequence.
Assembly geometry should be self-locating where practical and should reduce dependence on uncontrolled field measurement or skilled improvisation.
Components shall minimize the possibility of:
- Incorrect orientation.
- incomplete seating.
- wrong-part installation.
- false locking.
- inaccessible fasteners.
- hidden damage.
- incorrect sequence.
- premature load transfer.
- trapped moisture or contamination.
Where a connection has multiple states, the states should be physically and digitally distinguishable. Representative states may include:
- Approached.
- aligned.
- captured.
- temporarily retained.
- locked.
- verified.
- accepted.
- released.
Temporary assembly states shall be evaluated structurally. A connection that is safe when fully locked may be unstable during alignment or partial engagement.
Design shall account for realistic tolerances of all mating parts and for field conditions such as dust, coatings, minor damage, temperature, moisture, and limited access.
Assembly force, torque, insertion depth, fastening pattern, and permitted adjustment shall be defined where consequential.
The design should support replacement of damaged or sacrificial elements without unnecessary destruction of adjacent components.
Assembly completion shall be verifiable through direct observation, measurement, mechanical indicators, sensing, or governed evidence appropriate to criticality.
