Optical-Fiber-Embedding Sheet With Wider Adhesive Layer for Stable Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical-fiber-embedding sheets face issues with insufficient temporary fixation during application to placement objects, leading to peeling before the adhesive layer cures, which can disrupt the sensing process and increase labor costs.
Innovation Solution
An optical-fiber-embedding sheet with a base material, adhesive layer, and bonding adhesive layer, where the adhesive layer has a wider width than the bonding adhesive layer, ensuring sufficient temporary fixation until curing is complete, and includes a wire for sheet tearing to facilitate application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the adhesive layer has adhesiveness for temporary fixation, then the sheet can be temporarily fixed to the placement object, but the temporary fixation is insufficient and the sheet may be peeled off before curing is completed
Solution Approach 1:
The adhesive layer is divided into multiple segments along the width direction, creating a segmented adhesive structure that provides distributed fixation points while maintaining overall stability during the curing process
Solution Approach 2:
The adhesive layer has different adhesive properties in different regions, with higher adhesiveness in specific local areas to enhance temporary fixation at critical positions while maintaining overall bonding performance
2Ease of operation
If an optical fiber is fixed between sheets or to a member for placement, then labor for placement operation is reduced, but production cost increases and deformation of the placement object may not be accurately reflected
Solution Approach 1:
The optical fiber is extracted from the complex sheet structure and directly embedded in the adhesive layer, eliminating intermediate sheets or members while maintaining ease of placement operation
Solution Approach 2:
The optical fiber is preliminarily positioned and embedded in the adhesive layer before the adhesive is applied to the placement object, ensuring proper positioning while simplifying the overall structure
