Display Apparatus Hook Coupling for Thin Bezel Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display apparatuses require a significant area on the side surfaces for screw coupling, which increases the width of the bezel and conflicts with the need to minimize the side surface width except for the active display area.
Innovation Solution
The display apparatus incorporates a heat sink plate with a catch portion and a mold frame with a first hook, and optionally a top chassis with a second hook and window, allowing for coupling without the need for extensive side surface area, thereby reducing the overall width of the side surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to couple the top chassis, mold frame, heat sink plate, and bottom chassis, then reliable mechanical coupling is achieved, but the side surface width increases due to the required assembly area
Solution Approach 1:
The patent extracts the screw coupling function from the traditional assembly method and replaces it with hook-shaped coupling structures integrated into the chassis and mold frame. The first and second hooks are built into the top chassis and bottom chassis respectively, eliminating the need for separate screw fastening mechanisms and reducing the side surface width required for assembly.
Solution Approach 2:
The patent merges the coupling function with the structural components themselves. The top chassis includes integrated first hooks, and the bottom chassis includes integrated second hooks, combining the structural support function with the mechanical coupling function in a single integrated design, thereby eliminating the need for additional coupling components that would increase side surface width.
2Length of stationary object
If the side surface width is reduced for compact design, then device compactness is improved, but the area available for screw assembly is insufficient
Solution Approach 1:
The patent transitions from a two-dimensional screw insertion approach (requiring lateral access through the bezel) to a three-dimensional interlocking approach where hooks extend vertically and engage with corresponding receptacles. This dimensional change allows coupling to occur within the depth of the device rather than requiring lateral assembly space, enabling compact side surfaces while maintaining assembly feasibility.
3Length of stationary object
If hooks are used instead of screws for coupling, then side surface width is reduced, but coupling strength may be compromised
Solution Approach 1:
The patent implements a nested coupling mechanism where the first hooks of the top chassis extend downward and nest within corresponding receptacles in the mold frame, while the second hooks of the bottom chassis extend upward and nest within receptacles in the mold frame. This nested arrangement creates interlocking engagement that distributes mechanical loads effectively, maintaining coupling strength while eliminating the need for external screw fastening.
