Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different mounting equipment is used for various semiconductor light emitting device packages and heat sinks, then the light source module can be adapted to different automobile models, but manufacturing costs increase and quality control becomes difficult
Solution Approach 1:
The patent applies universality by designing a standardized mounting structure that can accommodate different semiconductor light emitting device packages and heat sinks through a single type of mounting equipment. The mounting structure includes a mounting board with standardized connection interfaces that can interface with various package types, eliminating the need for model-specific equipment while maintaining adaptability to different automobile lighting requirements
Solution Approach 2:
The patent utilizes parameter changes by incorporating adjustable mounting positions and configurable connection configurations on the mounting board. The mounting structure allows modification of electrical connection parameters and mechanical mounting parameters through software or reconfigurable hardware, enabling the same physical equipment to adapt to different package sizes and heat sink configurations without requiring different mounting equipment
2Ease of manufacture
If standardized mounting equipment is used for all light emitting device packages, then manufacturing costs decrease and quality control improves, but the ability to accommodate different automobile models may be limited
Solution Approach 1:
The mounting board is designed with universal interfaces and standardized connection protocols that can work with multiple package types and heat sink configurations. The standardized design enables consistent manufacturing processes across different product variants while the configurable connection options maintain compatibility with various automobile model requirements
Solution Approach 2:
The mounting structure is segmented into modular components including the mounting board, connection interfaces, and support structures. This segmentation allows the standardized mounting equipment to be configured for different applications by assembling appropriate modules, maintaining manufacturing simplicity while achieving adaptability to different automobile models through modular reconfiguration
