Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional PCB with fixed diode chips is used, then manufacturing precision is maintained, but adaptability deteriorates making it impossible to change light colors
Solution Approach 1:
The patent divides the lighting system into modular cassette light units that can be independently replaced. Each cassette unit contains a receptacle substrate with receptacle slots for holding light-emitting components, allowing users to swap between different color configurations without replacing the entire lighting board.
Solution Approach 2:
The receptacle substrate is designed with universal receptacle slots that can accommodate various types of light-emitting components. The same receptacle structure supports different color configurations and displaying patterns, making the system multi-functional and adaptable to different lighting requirements.
2Ease of repair
If traditional PCB with soldered diodes is used, then reliability is maintained, but ease of repair deteriorates making it difficult to replace failed diodes
Solution Approach 1:
The lighting system is segmented into replaceable cassette light units. When a light-emitting component fails, only the specific cassette unit needs to be removed and replaced, not the entire PCB assembly. This modular approach dramatically simplifies repair operations while maintaining reliable electrical connections through the receptacle interface.
Solution Approach 2:
The receptacle substrate incorporates elastic parallel cantilevers that automatically engage with the cassette light unit upon insertion, creating a self-locking mechanism. This allows users to easily install or replace light units without requiring specialized tools or technical expertise, enabling self-service maintenance.
3Ease of operation
If cassette light unit with elastic cantilevers is used, then ease of operation improves for assembly and disassembly, but device complexity increases
Solution Approach 1:
The elastic parallel cantilevers in the receptacle substrate automatically engage with the cassette light unit when inserted, creating a self-locking mechanism that secures the light unit without requiring additional fasteners or tools. This self-service feature greatly enhances ease of operation while keeping the structural complexity manageable.
Solution Approach 2:
The elastic cantilevers act as an intermediary mechanism between the receptacle substrate and the cassette light unit. They provide both mechanical engagement and electrical connection functions, simplifying the overall interface design while enabling easy assembly and disassembly operations.
4Reliability
If insulation material is added between metal plates, then reliability improves for electrical isolation, but device complexity increases
Solution Approach 1:
The receptacle substrate employs a composite structure combining conductive metal plates with insulating material layers. This composite design ensures reliable electrical isolation between different conductive elements while maintaining structural integrity and enabling compact integration of multiple functional layers within the receptacle assembly.
