Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flexible and independent power lines are used for connection between adjacent display units, then wiring flexibility is improved, but wiring complexity increases and safety hazards occur due to continuous connection with external power supply
Solution Approach 1:
The power line connection is segmented into modular plug assemblies and receptacle assemblies. Each display unit is equipped with its own power connection module, allowing independent connection and disconnection. This segmentation simplifies the overall wiring system while maintaining flexibility, as each module handles only its local connection without requiring continuous external power supply wiring throughout the entire display wall.
Solution Approach 2:
The power line connection transitions from a static continuous connection to a dynamic plugable connection. The plug assembly can be inserted into or removed from the receptacle assembly, allowing the connection state to change dynamically. This enables workers to disconnect power lines during assembly operations, eliminating safety hazards while preserving wiring flexibility when needed.
2Use of energy by moving object
If power lines are continuously connected with external power supply during assembly, then power availability is improved, but safety hazards increase due to risk of electric shock during assembly operations
Solution Approach 1:
The plug assembly is pre-equipped with power connection components before assembly operations begin. Workers can connect power to individual display units only when needed, rather than having continuous external power supply wiring installed beforehand. This preliminary preparation of modular power connections allows power to be available when required while eliminating the safety hazard of continuous energized wiring during assembly.
Solution Approach 2:
The continuous external power supply connection is extracted and replaced with individual plug assemblies at each display unit. This extraction removes the hazardous continuous power wiring from the assembly environment while preserving power availability at specific locations when plugs are connected. The power supply function is separated from the main assembly structure and distributed to individual units.
3Ease of manufacture
If traditional wiring methods are used for power lines, then connection simplicity is improved, but assembly efficiency decreases due to complex wiring operations
Solution Approach 1:
The power line connection components are merged into integrated plug assemblies that include all necessary electrical connections in a single modular unit. This combining of power connection elements simplifies the manufacturing process for each display unit and significantly improves assembly efficiency, as workers only need to connect the integrated plug to the receptacle rather than handling multiple separate wiring components.
