Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If modular connectors are used to connect cable harness modules, then adaptability and ease of assembly are improved, but sealing performance and vibration resistance deteriorate
Solution Approach 1:
The patent merges multiple cable harness modules into a single integrated connector housing that accommodates all modules simultaneously. The housing provides a unified sealing environment for all connector interfaces, eliminating the need for separate sealing at each modular interface while maintaining adaptability through the modular module arrangement within the housing.
2Adaptability or versatility
If modular connectors are used to connect cable harness modules, then adaptability and ease of assembly are improved, but vibration resistance deteriorates
Solution Approach 1:
The patent combines multiple modular connectors into a single rigid housing structure that provides unified mechanical support and vibration resistance for all connected modules. The housing acts as a single robust unit rather than multiple separate connections, thereby maintaining adaptability while improving vibration resistance.
3Adaptability or versatility
If individual plugs and sockets are used for each cable harness module, then adaptability is improved, but device complexity and production effort increase
Solution Approach 1:
The patent implements a universal housing design that can accommodate multiple different cable harness modules with varying configurations. The housing provides standardized mounting and connection interfaces for all modules, allowing the same housing structure to serve multiple functions and support different module arrangements without requiring separate specialized connectors for each variant.
Solution Approach 2:
The patent merges multiple individual plug and socket interfaces into a single integrated housing unit that provides all necessary connections simultaneously. This reduces the overall number of separate components and assembly steps while maintaining the adaptability to connect different module types through the unified housing structure.
4Adaptability or versatility
If cables for all possible variants are included in a wiring harness, then adaptability is improved, but weight and complexity increase
Solution Approach 1:
The patent segments the cable harness into separate modular units, each containing only the cables needed for specific variants. This allows selective assembly of modules based on the required configuration, eliminating unnecessary cables and reducing weight while maintaining adaptability through the modular architecture that can be configured for different variants.
