Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a leaf spring is fixed to the housing by use of a screw, then the optical component can be mounted, but the size of members increases and the mounting operation becomes complicated
Solution Approach 1:
The invention extracts and eliminates the screw and hole-forming operations from the mounting structure. The elastic member is designed to be mounted without any fastening elements, directly pressing the optical component against the base through its elastic deformation, thereby removing the complexity of screw fixation while maintaining secure mounting.
Solution Approach 2:
The elastic member serves itself by using its own elastic deformation to both mount itself to the base and secure the optical component. The holding portion of the elastic member automatically engages with the base through elastic deformation, eliminating the need for separate fastening operations or tools.
2Reliability
If a leaf spring is fixed to the housing by use of a screw, then the optical component can be mounted, but the size of members increases
Solution Approach 1:
The invention removes the need for holes and screws from the elastic member design, allowing for a more compact and streamlined structure. The elastic member can be designed as a continuous piece without openings for screw insertion, reducing its overall volume and simplifying its geometry.
3Reliability
If pressure is applied to the optical component by the elastic member, then the component is securely held, but the component may be damaged if pressure is too high
Solution Approach 1:
The elastic member provides dynamic pressure application through its elastic deformation capabilities. The pressure is automatically adjusted based on the component's position and the elastic member's material properties, ensuring sufficient holding force without exceeding damage thresholds. This dynamic adaptation eliminates the need for precise pre-calculation of fixed pressure values.
Solution Approach 2:
The invention utilizes changes in the elastic member's physical parameters (deformation amount, material elasticity) to control the pressing force. By selecting appropriate elastic materials and geometries, the system achieves optimal pressure levels that secure the component without causing damage, adapting to different component requirements.

AI summary
An optical component mounting structure includes an elastic member and a mounting portion. The elastic member applies pressure to an optical component toward a flat surface portion of a base. The mounting portion is provided at the base and mounts the elastic member. The elastic member has a pressing portion, a holding portion, and a positioning hole. The pressing portion has a tongue piece shape and elastically comes in contact with a light guide member. The holding portion supports one end of the pressing portion and holds elastically the mounting portion of the base. The positioning hole is formed through the holding portion and is to be engaged with each of a pair of positioning convex portions provided at the mounting portion of the base.
