Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If additional adjusting tools are used to align the optical axis, then the alignment precision is improved, but the device complexity and assembly inconvenience increase
Solution Approach 1:
The patent merges the optical component adjustment function directly into the housing structure by integrating rotatable elastic members that abut against the optical component. This eliminates the need for separate external adjusting tools, as the housing itself provides the adjustment mechanism through its built-in elastic members that can be rotated to push the optical component in radial directions.
Solution Approach 2:
The housing structure provides self-service adjustment capability through the rotatable elastic members that are built into the housing. The elastic members can be rotated by the user to automatically adjust the optical component orientation without requiring external adjusting tools or complex assembly procedures.
2Measurement precision
If external adjusting tools are used for optical axis calibration, then the alignment accuracy is improved, but the assembly process becomes more inconvenient
Solution Approach 1:
The patent combines the calibration function with the housing structure by integrating rotatable elastic members that can be directly manipulated during assembly. This eliminates the need for separate external adjusting tools, making the assembly process more convenient while maintaining calibration accuracy through the precise radial adjustment capability of the elastic members.
Solution Approach 2:
The housing structure enables self-service calibration by incorporating rotatable elastic members that can be directly adjusted during assembly. The elastic members provide a user-friendly interface for calibration without requiring complex external tools, thereby improving assembly convenience while maintaining measurement precision.
3Volume of moving object
If the laser emitter size is reduced, then the device miniaturization is improved, but the adjustment difficulty increases
Solution Approach 1:
The patent addresses the adjustment difficulty of miniaturized laser emitters by integrating rotatable elastic members directly into the housing structure. These elastic members provide a user-friendly adjustment mechanism that works effectively with small optical components, eliminating the need for complex external adjusting tools and making the adjustment process easier despite the reduced size of the laser emitter.

Implementation Method 1
The first elastic member is rotatably disposed on the first end and abuts against the third end. The second elastic member is rotatably disposed on the second end and abuts against the fourth end. A user may selectively rotate the first elastic member and/or the second elastic member to push the optical component to move in a radial direction of the through hole
