Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional wiring methods are used for humanoid robots, then the wiring assembly provides sufficient electrical connection, but the wiring becomes bulky and restricts robot motion
Solution Approach 1:
The wiring assembly is divided into multiple wire bundles, each serving specific functions (power, signal, data). These segmented bundles are routed through separate pathways and secured at different locations, allowing independent movement and reducing overall bulk while maintaining electrical connectivity.
Solution Approach 2:
Wire bundles are nested within protective conduits and routed through hollow chambers in the robot's skeletal structure. The wiring is embedded within the actuator housings and limb segments, allowing the wiring system to occupy minimal external volume while providing sufficient electrical connection.
2Reliability
If conventional wiring methods are used, then electrical connection is established, but the wiring is prone to mechanical stress and environmental damage
Solution Approach 1:
Wire bundles are pre-coated with protective insulation and routed through reinforced conduits before assembly. Strain relief fittings are installed at connection points to absorb mechanical stress before it reaches the wires. The wiring pathways are designed to avoid high-stress zones and moving joints.
Solution Approach 2:
Wire bundles are enclosed in flexible protective sheaths that allow movement while protecting against environmental damage. The conduits and housings containing the wiring are designed with flexibility to accommodate robot motion without exposing wires to mechanical stress or environmental contaminants.
3Ease of manufacture
If wiring extends through actuator openings, then electrical connection between actuators is achieved, but the wiring becomes exposed and vulnerable
Solution Approach 1:
Wire bundles are nested within the hollow chambers of actuator housings and limb segments. The wiring passes through protected pathways inside the actuator bodies rather than exposed external routes. Connection terminals are enclosed within sealed compartments, protecting wires from environmental exposure while maintaining electrical connectivity.
