Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple separate supports are used for substrate, primary optical means, and secondary optical means, then each component can be independently positioned, but the positioning process becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple separate supports into a single integrated support structure that simultaneously holds the substrate, primary optical means, and secondary optical means. This single support features integrated positioning elements such as indexing pins and clamping mechanisms that can precisely position all optical components relative to each other in one operation, eliminating the need for multiple separate positioning operations and reducing overall complexity.
Solution Approach 2:
The single support structure serves multiple functions: it supports the substrate, positions the primary optical means, positions the secondary optical means, and provides clamping mechanisms for securing all components. This multi-functional design consolidates what would otherwise require multiple specialized fixtures or supports, streamlining the positioning process while maintaining precision.
2Manufacturing precision
If precise positioning of primary optical means is required, then light beam formation is accurate, but the assembly process becomes time-consuming
Solution Approach 1:
The single support is designed with pre-configured positioning features such as indexing pins,定位 holes, and clamping mechanisms that are already in place before component assembly. These pre-prepared positioning elements guide the optical components into their correct positions automatically during assembly, eliminating the need for time-consuming manual alignment and adjustment operations.
Solution Approach 2:
By integrating multiple positioning and clamping functions into a single support structure, the patent enables simultaneous positioning of multiple optical components in one assembly operation. This combined approach allows all optical elements to be positioned and secured together rather than individually, significantly reducing assembly time while maintaining precise alignment.
3Manufacturing precision
If multiple positioning mechanisms are used for different optical components, then positioning accuracy is maintained, but the device structure becomes more complex
Solution Approach 1:
The patent integrates multiple positioning functions into a single unified support structure. Instead of using separate positioning mechanisms for the substrate, primary optical means, and secondary optical means, the single support incorporates all positioning features (indexing pins, clamping elements, positioning holes) in one integrated component, reducing the overall number of parts and simplifying the device structure.
Solution Approach 2:
The single support structure is designed as a multi-functional component that performs positioning, support, and clamping functions for all optical elements simultaneously. This universal design eliminates the need for multiple specialized positioning devices, reducing structural complexity while maintaining the ability to precisely position all components through its integrated multi-functional features.
