Bent Connection Member for Display Board Thickness Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display device board fixing methods result in increased thickness due to the need for a protrusion and direct contact with engagement members, leading to potential damage and electrical shorts.
Innovation Solution
A board supporting structure with a receiving portion on the main frame and a connection member that includes a protrusion inserted into a slot on the board, allowing for secure fixation without direct contact and minimizing thickness, using a separate connection member that can be bent to support the board at a height equal to or lower than the main frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protrusion is used to fix the board to the main frame, then the board can be securely fixed and insulated from the main frame, but the display device thickness increases
Solution Approach 1:
The connection member is bent at least once in the vertical direction, changing its shape from a straight line to a three-dimensional form. This allows the connection member to connect the board to the main frame while accommodating the thickness constraint, as the bent configuration enables the board to be fixed at a height equal to or lower than the main frame surface.
2Strength
If engagement members are used to fix the board, then the board can be securely attached, but the board may be damaged due to direct contact with the engagement members
Solution Approach 1:
The connection member serves as an intermediary component between the engagement member (screw) and the board. The engagement member fastens the connection member to the main frame, while the connection member's bent structure and positioning prevent the engagement member from directly contacting the board, thus eliminating the risk of board damage while maintaining fixation strength.
3Ease of operation
If a separate connection member is used instead of direct protrusion coupling, then board damage is prevented and installation is facilitated, but the device complexity increases
Solution Approach 1:
The fixing structure is segmented into distinct functional components: the connection member with its specific bent shape that facilitates easy board installation, and the engagement member for secure attachment to the main frame. This segmentation allows each component to perform its specific function optimally while maintaining overall simplicity.
Solution Approach 2:
The connection member is designed with a specific bent shape that enables it to automatically position and support the board at the correct height relative to the main frame. The vertical bend allows the connection member to self-adjust to the thickness constraints, eliminating the need for complex adjustment mechanisms or precise manual positioning during installation.

AI summary
Provided are a display device and a board supporting structure. The board supporting structure includes: a board; a main frame to which the board is fixed; a receiving portion formed at the main frame and on which the board is placed; and a connection member being a separate component fixing the board to the main frame and including a first portion coupled to the main frame and a second portion coupled to the board. Accordingly, an increase in thickness of the display device due to installation of the board is reduced, the performance reliability of the board is improved, the installation of the board is facilitated, and damage to the board is prevented.
