Detachable Display Panel Mounting for Damage-Free Rework
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in efficient reworking without damaging the cover member and display panel, leading to issues like cracks and shrinkage during low-temperature disassembly and the need for additional materials in reassembly.
Innovation Solution
A display device design featuring attachable and detachable adhesive members, such as Velcro fasteners or dual locks, allows for easy separation and reassembly of the display panel and cover member without low-temperature processes, reducing material residues and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional adhesive methods are used to fix the display panel to the cover member, then strong bonding is achieved, but reworking causes damage such as cracks and shrinkage
Solution Approach 1:
The adhesive member is divided into two separate parts: a first adhesive member attached to the display panel and a second adhesive member attached to the cover member. These segmented adhesive parts can be independently removed and reattached, enabling reworking without damage while maintaining bonding strength during normal use
Solution Approach 2:
The adhesive system transitions from a static permanent bond to a dynamic reversible bond. The first and second adhesive members can be detached and reattached multiple times, providing adaptability for reworking while maintaining stable bonding during operation
2Ease of operation
If low-temperature disassembly is used to separate the display panel and cover member, then separation is achieved, but defects such as cracks and shrinkage occur
Solution Approach 1:
By segmenting the adhesive into removable first and second adhesive members, the display panel and cover member can be separated at room temperature without applying stress or heat that would cause cracks or shrinkage, maintaining product integrity during separation
Solution Approach 2:
The detachable adhesive members act as intermediaries that facilitate separation without direct mechanical stress on the display panel or cover member, eliminating the need for low-temperature disassembly processes that cause damage
3Ease of manufacture
If additional materials are used for reassembly, then bonding is restored, but material costs and complexity increase
Solution Approach 1:
The first and second adhesive members are pre-attached to the display panel and cover member respectively during initial assembly. This preliminary action ensures that when reworking is needed, the adhesive components are already in place and can be simply reattached without requiring additional materials or complex reassembly procedures
Solution Approach 2:
Instead of discarding the adhesive system after separation, the first and second adhesive members are recovered and reused for reassembly. This eliminates the need for additional materials while maintaining reassembly feasibility
