Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional wiring assemblies are used in humanoid robots, then wiring can be routed externally, but the wiring becomes bulky and restricts robot motion
Solution Approach 1:
The wiring assembly is nested within the actuator housing, with wires passing through internal channels and bore openings. This internal routing eliminates external wire bundles, reducing bulk and allowing greater range of motion while maintaining electrical connectivity between components.
Solution Approach 2:
The wiring transitions from external three-dimensional routing to internal constrained pathways within the actuator. Wires are guided through specific channels and openings, changing their spatial arrangement from loose external bundles to structured internal routes, reducing interference with motion.
2Reliability
If wiring extends through actuator openings, then connectivity between actuators is achieved, but wires are exposed to mechanical stress and environmental damage
Solution Approach 1:
Strain relief members are installed at critical points where wires pass through actuator openings and housing. These members provide mechanical protection and stress distribution before wires are exposed to harsh conditions, preventing damage from mechanical stress and environmental factors.
Solution Approach 2:
The strain relief members act as intermediary components between the wiring and the harsh environment. They absorb and distribute mechanical stresses, shielding the wires from direct exposure to damaging forces while maintaining electrical connectivity.
3Ease of manufacture
If wiring assembly is simplified for easier assembly, then manufacturing time is reduced, but signal integrity may be compromised
Solution Approach 1:
The wiring assembly is segmented into modular components including wire bundles, connectors, and strain relief members that can be assembled separately. This modular approach simplifies the assembly process while maintaining signal integrity through proper connection points and routing structures.
Solution Approach 2:
Wires are pre-routed through actuator openings and housing channels during manufacturing, with strain relief members pre-installed at critical locations. This preliminary preparation simplifies final assembly while ensuring signal integrity is maintained through proper wire positioning and protection.
