Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing matrix illumination modules use complex mounting structures to achieve precise positioning, then positioning accuracy is improved, but device complexity increases and assembly/disassembly becomes difficult
Solution Approach 1:
The patent divides the illumination module into separate functional components: LED light sources, primary optical elements, and a projection system. Each component has its own mounting bracket with independent positioning features. This segmentation allows each part to be precisely positioned and adjusted independently, achieving high positioning accuracy without requiring an overly complex integrated structure.
Solution Approach 2:
The patent employs a nested mounting structure where the LED circuit board mounts on a first bracket, the primary optical element mounts on a second bracket that integrates with the first, and the projection system mounts on the same bracket. This nested arrangement achieves precise positioning through multiple levels of integrated mounting brackets with positioning holes and locating features, while maintaining structural compactness.
2Device complexity
If existing matrix illumination modules use integrated mounting structures, then structural compactness is achieved, but disassembly and assembly become very difficult
Solution Approach 1:
The patent segments the mounting structure into multiple independent brackets (first mounting bracket for LED circuit board, second mounting bracket for primary optical element, third mounting bracket for projection system). Each bracket can be independently assembled and disassembled, maintaining structural compactness while enabling easy maintenance and replacement of individual components without disassembling the entire module.
Solution Approach 2:
The patent incorporates adjustable and removable mounting features including positioning holes, locating pins, and detachable connections between brackets. These dynamic mounting mechanisms allow the structure to be compact during operation but easily separated for assembly and disassembly, transforming the static integrated structure into a modular system with flexible configuration.
3Device complexity
If existing matrix illumination modules lack independent auxiliary light pattern design, then device complexity is reduced, but adaptability to different driving environments decreases
Solution Approach 1:
The patent designs the illumination module with multi-functional capabilities: the LED light sources can operate in multiple modes (high beam, low beam, auxiliary lighting), the primary optical elements can be configured for different light patterns, and the projection system can display various auxiliary light patterns. This universal design allows a single module structure to adapt to different driving environments and lighting requirements without increasing overall structural complexity.
Solution Approach 2:
The patent implements dynamic control of light patterns through independent control of LED groups and projection system configurations. The module can dynamically switch between high beam, low beam, and auxiliary lighting modes, and adjust light patterns based on driving conditions. This dynamic adaptability is achieved through control circuits that manage different LED groups and projection elements, allowing the system to respond to varying environmental requirements.
