Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wires are used to connect circuit boards linearly for electrical connection, then electrical connection is achieved, but assembly becomes cumbersome and assembly efficiency decreases
Solution Approach 1:
The patent extracts and eliminates the wire component from the electrical connection system. Instead of using wires to connect circuit boards, the invention integrates electrical contacts directly into the circuit board structure, allowing direct electrical connection without intermediate wiring components.
Solution Approach 2:
The patent merges the electrical connection function with the mechanical support structure. The circuit board is designed with integrated contacts that combine structural support and electrical conduction functions into a single unified component, eliminating the need for separate wire connections.
2Device complexity
If wires are used to connect multiple light-emitting bodies, then electrical connection is achieved, but the structure becomes complex and uniform luminescence cannot be realized
Solution Approach 1:
The patent segments the light-emitting bodies into modular units, each with integrated electrical contacts. This segmentation allows for standardized connection interfaces that simplify the overall structure and enable uniform electrical connection across all modules, resulting in uniform luminescence.
Solution Approach 2:
The circuit board is designed with universal connection features that serve multiple functions: mechanical support, electrical connection, and positioning. This multi-functionality reduces structural complexity while ensuring uniform electrical distribution to all light-emitting elements.
3Ease of manufacture
If wires are welded to circuit boards for fixing, then electrical connection is achieved, but the appearance becomes messy and aesthetic appeal decreases
Solution Approach 1:
The patent removes the wire component entirely from the design, extracting the aesthetic problem caused by visible wiring. The electrical connection is achieved through integrated contacts that are concealed within the circuit board structure, resulting in a clean, wire-free appearance.
4Productivity
If conventional wire-based connection is used, then electrical connection is achieved, but time-consuming assembly process reduces productivity
Solution Approach 1:
The patent incorporates electrical contacts directly into the circuit board during manufacturing, performing the electrical connection preparation in advance. This preliminary action eliminates the need for time-consuming wire welding and connection steps during assembly, significantly reducing assembly time and improving productivity.
