Solution Overview
Problem
Optical fibers are prone to breakage or cracking due to length changes caused by environmental conditions, leading to deterioration in light distribution performance and unintended image shape changes.
Innovation Solution
An optical fiber fixing device with a sub-bracket, main bracket, and elastic member that allows the sub-bracket to slide within the main bracket, using an elastic member to accommodate length changes, preventing breakage and unintended image shape changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the optical fiber is fixed rigidly to prevent movement, then the fiber position is stable, but the fiber breaks or cracks when length changes occur due to temperature variations
Solution Approach 1:
The bracket is designed with a sliding mechanism that allows dynamic adjustment of the optical fiber's position. The sub-bracket can slide along the main bracket in response to fiber length changes, transforming the rigid fixed structure into a dynamic adaptive system that prevents fiber breakage while accommodating thermal expansion and contraction.
Solution Approach 2:
The device utilizes the elastic properties of the elastic member to respond to changes in fiber length. When the fiber expands or contracts due to temperature variations, the elastic member deforms accordingly, allowing the sub-bracket to move and maintain proper fiber tension without causing breakage or cracking.
2Reliability
If the optical fiber is allowed to expand and contract freely, then the fiber is protected from breakage, but the image shape becomes distorted and unclear
Solution Approach 1:
The sliding bracket mechanism provides controlled dynamic movement that allows the fiber to expand and contract without excessive tension or compression. This controlled movement prevents fiber breakage while maintaining the fiber's proper positioning, thereby preserving image shape accuracy and preventing distortion.
Solution Approach 2:
The elastic member acts as an intermediary element between the fixed main bracket and the movable sub-bracket. It absorbs the mechanical stress caused by fiber length changes, mediating between the need for fiber freedom to prevent breakage and the need for stable positioning to maintain image quality.
3Ease of manufacture
If a fixed bracket structure is used to hold the optical fiber, then the installation is simple, but the device cannot respond to length changes causing fiber deformation
Solution Approach 1:
The bracket structure incorporates a sliding mechanism that adds dynamic responsiveness while maintaining relatively simple installation. The sub-bracket can slide along the main bracket to accommodate fiber length changes, preventing deformation without requiring complex adjustment procedures or installation processes.
Solution Approach 2:
The elastic member introduces flexibility into the bracket system, allowing it to respond to changes in fiber length. This parameter change capability is integrated into the simple bracket structure, enabling the device to adapt to thermal expansion and contraction while maintaining ease of installation and fiber deformation prevention.

AI summary
An optical fiber fixing device is capable of immediately responding to changes in the length of an optical fiber caused by environmental changes. Breakage or cracking of the optical fiber attributable to changes in the length of the optical fiber and unintended changes in the shape of an image may thereby be prevented.
