Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flexible and independent power lines are used for connection between display units, then wiring flexibility is improved, but wiring complexity increases and safety risks occur during continuous assembly
Solution Approach 1:
The power line connection is segmented into modular plug and receptacle components. Each display unit is equipped with a plug assembly containing electrically conductive members that can be independently connected to receptacle assemblies on adjacent units, eliminating the need for continuous wiring throughout the entire display structure.
Solution Approach 2:
A switch assembly is introduced as an intermediary component between the electrically conductive members and the external power supply. This switch assembly controls the electrical connection state, allowing the system to transition between connected and disconnected states, thereby simplifying the wiring control mechanism while maintaining flexibility.
2Use of energy by moving object
If power lines are connected with external power supply during continuous assembly, then power supply capability is improved, but safety accidents are likely to occur
Solution Approach 1:
The electrical connection state is made dynamic through the switch assembly, which can transition the electrically conductive members between connected and disconnected states. This dynamic control allows the system to be safely disconnected during assembly operations and connected during normal operation, eliminating safety hazards while maintaining power supply capability.
Solution Approach 2:
The plug and receptacle assemblies are designed to be self-contained with integrated switch control, allowing each display unit to independently manage its own electrical connection state without requiring external intervention or complex centralized control systems.
3Productivity
If display units are continuously assembled with power lines connected, then assembly continuity is improved, but safety hazards increase
Solution Approach 1:
The electrical connection is implemented as a periodic action rather than a continuous state. The switch assembly enables the system to alternate between disconnected states during assembly operations and connected states during normal display operation, allowing continuous productivity while eliminating safety hazards through periodic disconnection.
