Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wires are soldered to lamp ends for power supply, then electrical connection is achieved, but wires are liable to be damaged during assembly requiring reassembly
Solution Approach 1:
The patent extracts the vulnerable wire component from the assembly process and replaces it with integrated conductive structures (connecting tubes and conductive patterns) that are permanently formed as part of the frame. This eliminates the wire soldering step that causes damage and reassembly requirements.
Solution Approach 2:
The patent merges the electrical connection function directly into the frame structure by integrating connecting tubes and conductive patterns with the frame body. This combines the structural support function with the electrical power supply function, eliminating separate wire components.
2Reliability
If wires are used for power supply to lamps, then electrical connection is established, but assembly complexity increases due to wire handling and soldering
Solution Approach 1:
The patent merges the electrical connection function directly into the frame structure by integrating connecting tubes and conductive patterns with the frame body. This combines the structural support function with the electrical power supply function, eliminating separate wire components and reducing assembly complexity.
Solution Approach 2:
The patent removes the wire component entirely from the system and replaces it with integrated conductive structures. This extraction eliminates the need for wire handling, routing, and soldering operations that complicate the assembly process.
3Reliability
If conventional wire-based power supply is used, then lamps can be powered, but mass production efficiency is reduced due to wire damage and reassembly requirements
Solution Approach 1:
The patent performs preliminary action by pre-forming the conductive patterns and connecting tubes as integral parts of the frame during frame manufacturing. This eliminates the need for subsequent wire installation and soldering steps during assembly, significantly improving mass production efficiency.
Solution Approach 2:
The patent extracts the wire component from the assembly process and replaces it with pre-formed integrated conductive structures. This eliminates wire damage issues and reassembly requirements that plague conventional wire-based power supply systems in mass production environments.
