Display Frame Diagonal Restraint Bezel Width Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses have a wide bezel width due to the exposure of the pad portion for signal connection, which increases the overall thickness and reduces the display's aesthetic appeal and usability.
Innovation Solution
A frame for display is designed with first to fourth frame members connected in a diagonal band shape, featuring restraint members with protrusions and grooves to prevent twisting and sliding, allowing for a compact assembly that minimizes bezel width by integrating the panel support frame and rear cover, thus hiding the pad portion from view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the pad portion is exposed for signal connection, then electrical connection is achieved, but the bezel width increases
Solution Approach 1:
The pad portion is extracted from the front viewable area and positioned at the rear of the display apparatus. The rear cover includes a pad portion receiving structure that houses the exposed pad portions, separating the electrical connection function from the front aesthetic area, thereby reducing bezel width while maintaining connection reliability
Solution Approach 2:
The pad portion connection is moved from the front dimension (visible area) to the rear dimension (hidden area). The rear cover structure provides a three-dimensional space to accommodate the pad portions, transitioning the connection interface from a front-facing exposure to a rear-facing integrated structure
2Length of moving object
If the front case covers the driving circuit and pad portion, then protection is achieved, but the bezel width increases
Solution Approach 1:
The protection function is moved from the front case (which increased bezel width) to the rear cover structure. The rear cover includes a pad portion receiving structure and driving circuit receiving structure that provide protection in the rear dimension, eliminating the need for a protruding front case
Solution Approach 2:
The protection functions for the pad portion and driving circuit are merged into the rear cover structure. The rear cover integrates multiple protective features (pad portion receiving structure, driving circuit receiving structure) into a single component, providing comprehensive protection without increasing front bezel width
3Stability of the object's composition
If frame members are connected with twisting and sliding, then assembly is simple, but structural stability deteriorates
Solution Approach 1:
The connection structure uses asymmetric features (protrusions and corresponding grooves) on the frame members. This asymmetric design prevents twisting and sliding by ensuring that components can only be assembled in the correct orientation, providing inherent stability while maintaining relatively simple assembly
Solution Approach 2:
The connection structure uses intermediary elements (protrusions and grooves) that mediate between frame members. These features act as mechanical intermediaries that guide alignment and prevent misalignment during assembly, ensuring structural stability without requiring complex assembly procedures
