Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the lamp size is increased to improve visibility, then the irradiation range and visibility are improved, but the device complexity and installation space requirements increase
Solution Approach 1:
The reverse guide lamp is divided into multiple independent light sources (first reverse guide light source and second reverse guide light source) that can be positioned at different locations. This segmentation allows the lamp to achieve wide coverage and high visibility without requiring a single large lamp structure, thus resolving the contradiction between visibility and device size.
Solution Approach 2:
The patent combines multiple functional elements into an integrated lamp assembly including housing, bezel, multiple light sources, and reflection devices. By merging these components into a coordinated system, the lamp achieves enhanced visibility and irradiation range while maintaining a compact overall structure that doesn't excessively increase device complexity.
2Device complexity
If the lamp is positioned at the rear of the vehicle to maintain compact size, then the device complexity is reduced, but the visibility and stability are deteriorated
Solution Approach 1:
The patent applies local quality by creating a protruding region on the rear surface of the housing that extends beyond the bezel. This localized structural modification allows the first light source to be positioned in a way that optimizes its irradiation angle and visibility without requiring a complete redesign of the entire lamp structure, thus maintaining device simplicity while improving visibility.
Solution Approach 2:
The patent utilizes the protruding region to create a three-dimensional arrangement where the first light source is positioned at a different spatial level relative to the second light source. This dimensional arrangement allows both light sources to achieve optimal irradiation angles and coverage areas, improving overall visibility without increasing the lamp's footprint or structural complexity.
3Illumination intensity
If the optical module is inclined to improve light irradiation angle, then the visibility is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The protruding region is pre-formed as an integral part of the housing structure during the housing manufacturing process. This preliminary action creates a built-in mounting feature that automatically provides the required inclination angle for the first optical module, eliminating the need for separate angle adjustment mechanisms and reducing manufacturing precision requirements for the optical module installation.
Solution Approach 2:
The protruding region acts as an intermediary structure between the housing and the first optical module. It serves as a pre-configured mounting platform that provides the necessary inclination angle, thereby mediating between the housing structure and the optical module to achieve the desired light irradiation angle without requiring high precision adjustment of the optical module itself.
