Stretch-Release Adhesive Tape Handle for Display Panel Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The detachment of a handle member from double-sided adhesive tape during the removal of a display panel in electronic devices, such as laptops, is problematic, especially when structural constraints hinder the placement of a tab for stretching, leading to adhesive residue and difficulty in panel removal.
Innovation Solution
A tape member with a sheet-shaped handle member connected to double-sided adhesive tape, wound in a direction intersecting the tape's longitudinal direction, and a dumbbell-shaped portion to secure the handle member, preventing detachment during stretching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sheet-shaped handle member is connected to the double-sided adhesive tape to enable stretching release, then the ease of operation is improved, but the reliability deteriorates because the handle member may come off the adhesive tape during stretching
Solution Approach 1:
The handle member is wound around the double-sided adhesive tape in a nested configuration, where the handle member surrounds the tape in a direction intersecting the tape's longitudinal direction. This nesting structure ensures that the handle member remains securely attached to the adhesive tape during stretching operations, preventing detachment while maintaining ease of operation.
2Ease of operation
If the handle member is made long to extend to the lateral of the display panel, then the ease of operation is improved, but the reliability deteriorates because the handle member is more likely to come off the adhesive tape during stretching
Solution Approach 1:
The handle member is wound around the double-sided adhesive tape in a nested configuration, where the handle member surrounds the tape in a direction intersecting the tape's longitudinal direction. This nesting structure ensures that the handle member remains securely attached to the adhesive tape during stretching operations, preventing detachment while maintaining ease of operation.
3Ease of operation
If a tab is used to hold when stretching the tape, then the ease of operation is improved, but the device complexity increases due to structural constraints hindering tab placement
Solution Approach 1:
The handle member is extracted as a separate component that can be independently positioned and connected to the adhesive tape. This extraction allows the handle member to be placed in optimal positions for operation without being constrained by the chassis structure, eliminating the need for complex tab integrations into the chassis while maintaining ease of operation.
