Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate optical components (reflecting component, light-shielding plate, lens, mounting bracket) are used to form the lighting module, then the lighting function can be achieved, but the device complexity increases and manufacturing precision requirements increase
Solution Approach 1:
The patent merges the reflecting component, light-shielding plate, lens, and mounting bracket into a single integrated optical component. The optical component includes a housing with an integrated reflecting surface, light-shielding plate, and lens that work together as one unified structure, eliminating the need for multiple separate parts and their associated mounting brackets.
Solution Approach 2:
The integrated optical component performs multiple functions simultaneously: the housing provides structural support and reflection, the integrated light-shielding plate controls light distribution, and the lens focuses and shapes the light beam. This multi-functional design replaces what previously required multiple specialized components.
2Reliability
If multiple separate optical components are assembled together, then the lighting module can be constructed, but manufacturing and assembling errors increase affecting light shape precision
Solution Approach 1:
By integrating the reflecting surface, light-shielding plate, and lens into a single molded optical component, the patent eliminates cumulative assembly errors that would occur when multiple separate parts are fitted together. The light path is precisely controlled within the integrated structure without requiring high-precision assembly between multiple components.
3Reliability
If traditional separate components are used, then optical functions are achieved, but the length of the lighting module increases due to long light propagation distance
Solution Approach 1:
The patent redesigns the light path to fold back on itself within the integrated optical component. The light reflects off the reflecting surface, interacts with the light-shielding plate, and passes through the lens in a compact folded configuration rather than a linear arrangement, significantly reducing the overall length of the lighting module.
4Reliability
If additional components like light-shielding plate and mounting bracket are added, then lighting control is improved, but the cost of the lighting module increases
Solution Approach 1:
The patent combines the light-shielding plate with the housing and optical elements into a single integrated component that is molded as one piece. This integration eliminates the need for separate manufacturing and assembly of the light-shielding plate and mounting bracket, reducing part count, assembly steps, and overall manufacturing cost while maintaining precise light control functionality.
