Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If active coupling method is used, then coupling precision can be achieved, but device complexity and cost increase due to requiring special coupler
Solution Approach 1:
The patent extracts and removes the special coupler component from the coupling system. Instead of using a coupler to adjust and maintain the position of the optical lens module, the invention directly fixes the optical lens module to the PCB through a fixing bracket, eliminating the need for the coupler while maintaining coupling precision through direct mechanical positioning.
Solution Approach 2:
The patent introduces a fixing bracket as an intermediary component between the optical lens module and the PCB. This fixing bracket provides direct mechanical support and positioning, replacing the need for active coupling mechanisms while ensuring stable and precise optical path coupling.
2Manufacturing precision
If passive coupling method is used, then coupling precision can be achieved, but device complexity and cost increase due to requiring two cameras
Solution Approach 1:
The patent extracts and removes the camera-based measurement system from the coupling process. Instead of using two cameras to capture images and calculate positions, the invention uses direct mechanical positioning through the fixing bracket and lens bracket assembly, eliminating complex optical measurement equipment.
Solution Approach 2:
The patent replaces the optical measurement system (cameras) with a mechanical positioning system. The fixing bracket and lens bracket provide direct mechanical alignment and positioning of the optical lens module, substituting complex optical measurement and calculation with simple mechanical structures.
3Loss of time
If UV glue is used for fixing, then fast curing is achieved, but fixation strength is insufficient leading to potential deviation during manual operations
Solution Approach 1:
The patent performs preliminary mechanical positioning and fixation using the fixing bracket and lens bracket assembly before any glue curing takes place. The mechanical structures provide immediate and sufficient fixation strength to prevent deviation during manual operations, eliminating the need for UV glue as the primary fixation method.
Solution Approach 2:
The patent replaces the chemical fixation method (UV glue) with a mechanical fixation system consisting of the fixing bracket and lens bracket. This mechanical system provides immediate and sufficient fixation strength without relying on the slow-curing properties of adhesives, preventing any potential deviation during assembly operations.
