Display Panel Module Removable Mount for Damage-Free Rework
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panel modules for tablet computers face challenges in disassembly due to precise alignment and adhering issues, leading to high manufacturing costs and potential damage to touch panels during rework, especially with large-area and thin designs.
Innovation Solution
A display panel module design featuring a removable element with one end fixed on the display panel and the other end removably attached to the frame's inner wall, using locking holes, embedding components, and viscous materials to allow for easy disassembly without direct contact, thus preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If glue (double sided tape) is used to adhere the touch panel and the frame, then assembling time is saved, but disassembly becomes difficult and causes damage to the touch panel and frame
Solution Approach 1:
The invention introduces a removable element that segments the connection between the touch panel and the frame. Instead of direct adhesive bonding between the panel and frame, the removable element acts as an intermediate component that can be independently removed, allowing the touch panel to be separated from the frame without damage while maintaining assembly efficiency.
Solution Approach 2:
The removable element serves as an intermediary component between the touch panel and the frame. It provides the adhesive bonding function while being designed as a separate, removable piece. This mediator allows the system to benefit from adhesive assembly speed while enabling damage-free disassembly by removing the intermediary element rather than separating directly bonded components.
2Device complexity
If the touch panel and the frame are directly adhered by glue, then the structure is simple, but rework becomes difficult and manufacturing cost increases
Solution Approach 1:
By segmenting the connection system into the removable element and the adhesive layer, the invention achieves a balance between structural simplicity and reworkability. The removable element is a simple component that enables easy removal and rework, while the overall structure remains straightforward without requiring complex mechanisms.
Solution Approach 2:
The removable element is designed to be discarded or replaced rather than permanently bonded. This allows for easy rework by removing the removable element, recovering the touch panel and frame for reuse, and reducing manufacturing costs associated with damaged components.
3Ease of operation
If force is used to disassemble the adhered touch panel and frame, then disassembly can be achieved, but fragmentation of glass substrate, scratch of ITO conductive film, or fracture of the frame occurs
Solution Approach 1:
The removable element acts as a sacrificial intermediary that absorbs the disassembly process. By removing this intermediate component rather than forcing separation of the touch panel and frame, the harmful forces are directed at the removable element which is designed to be removed without causing damage to the valuable components.
Solution Approach 2:
The removable element provides beforehand cushioning by being positioned between the touch panel and frame during assembly. This intermediate layer prevents direct force transmission to the fragile components during disassembly, cushioning them from damage while enabling the necessary separation.
