Display Frame Projection and Cutaway for Tool Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid crystal display devices face difficulties in easily detaching the upper frame from the lower frame during manufacturing or reworking due to insufficient gaps for tool insertion, making the process challenging.
Innovation Solution
The display device design incorporates a first frame with a projection and a second frame with a cut-away section, allowing for easy fitting and detachment by ensuring a larger interval for tool access, enhancing the fitting strength and ease of disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the upper frame and lower frame are fit tightly to each other, then the fitting strength is improved, but the gap for tool insertion becomes insufficient making detachment difficult
Solution Approach 1:
The side wall of the lower frame is segmented by forming a through-hole that divides it into upper and lower portions. This segmentation allows a detaching tool to be inserted through the hole to apply force to the claw, enabling detachment while maintaining the overall tight fit between frames for structural strength.
Solution Approach 2:
A detaching tool is introduced as an intermediary element that passes through the through-hole in the lower frame's side wall. This tool mediates the detachment process by allowing external force to be applied to the claw from the inside, facilitating separation without compromising the tight fitting design.
2Strength
If the claw is engaged deeply with the opening for strong fixation, then the fitting strength is improved, but the gap for tool insertion becomes insufficient
Solution Approach 1:
The side wall is segmented by creating a through-hole that passes completely through it, providing a dedicated pathway for tool insertion. This segmentation allows the claw to engage deeply with the opening for strong fixation while simultaneously providing access for detachment tools through the hole.
3Volume of moving object
If the side walls are positioned close together for compact design, then the device size is reduced, but the gap for tool insertion becomes insufficient
Solution Approach 1:
The side wall is segmented by forming a through-hole, creating a localized access point that allows detachment tools to reach the claw engagement. This segmentation enables compact overall device dimensions while providing the necessary access for manufacturing and reworking operations.

AI summary
A display device includes a display panel provided with a display surface on which an image is displayed, a back light provided below the display panel, a first frame provided with a first edge enclosing the display surface above the display panel and a first side plate portion provided on the first edge so as to extend in a direction orthogonal to the display surface, and a second frame provided with a second edge enclosing a light transmissive surface of the back light and a second side plate portion provided on the second edge to be opposed to an inner surface of the first side plate portion. The first side plate portion includes a first projection, and the second side plate portion includes a cut-away section in a position opposed to the first projection.
