Display Module with Buffer Support for Adhesive-Free Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable devices with displays, such as electronic watches, require adhesive fixation of the display, making it difficult to repair or replace the display without replacing other components.
Innovation Solution
A module comprising a display unit, a circuit board with a shield member covering circuit elements, and a buffer member sandwiched between the display and the circuit board, allowing stable holding without adhesive fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display is adhesively fixed to the windshield member, then the display is stably supported and not movable, but the display cannot be removed and repaired when defective
Solution Approach 1:
The display assembly is segmented into separable components: the display unit, the windshield member, and the circuit board with shield member. This segmentation allows the display to be independently removed and replaced without adhesives, while maintaining stable support through the modular structure where the display rests on the shield member and is positioned between the windshield member and circuit board.
2Reliability
If the display is adhesively fixed to the windshield member, then the display is securely held, but many components must be replaced including the windshield member
Solution Approach 1:
The device is divided into independent modules: display unit, windshield member, circuit board, and shield member. The display rests on the shield member which is positioned on the circuit board, creating a modular stack. This segmentation means that if the display is defective, only the display unit needs replacement, not the entire assembly including the windshield member.
Solution Approach 2:
The display unit is extracted as a separate, removable component from the overall assembly. By removing adhesive fixation and positioning the display on the shield member with space for access, the display can be independently taken out and replaced without affecting other components like the windshield member or circuit board.
3Reliability
If adhesive fixation is used, then the display is firmly attached, but assembly time and component count increase
Solution Approach 1:
The adhesive fixation process is extracted and removed from the assembly. Instead, the display is held in position by the modular structure where it rests on the shield member and is positioned between the windshield member and circuit board, eliminating the need for adhesive application and curing time.
Solution Approach 2:
The shield member and the positioning structure between the windshield member and circuit board provide self-contained support for the display. The display is held firmly by the mechanical arrangement of these components rather than requiring additional adhesive materials or complex fixation mechanisms.

AI summary
It is possible to stably hold a display inside a device without adhesively fixing the display. A module as a holding structure of a display unit 4 which is a display includes: the display unit 4 which is the display having a flat plate shape; a circuit board 6 disposed below the display unit 4 to overlap the display unit 4, and equipped with a shield member 7 that covers a circuit element 61 on a surface facing the display unit 4; and a buffer member 8 that is disposed on an upper surface of the shield member 7 and abuts on a lower surface of the display unit 4.
