Deformable Frame Coupling Mechanism for Tool-Free LCD Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display television coupling mechanisms make it difficult to disengage the middle frame from the back plate without tools, as the protruding hook engages tightly with the engagement hole, preventing easy removal.
Innovation Solution
A coupling mechanism featuring a deformable frame unit with engaging members that extend through stepped engaging holes on the back plate, allowing for disengagement and removal of the frame from the back plate without screws or tools, by creating a gap between the frame and back plate to facilitate deformation and disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the protruding hook engages tightly with the engagement hole to secure the frame to the back plate, then the coupling strength is improved, but the ease of disengagement deteriorates
Solution Approach 1:
The frame body is designed to be deformable, allowing it to change shape during disengagement. When force is applied, the frame body deforms to create a gap between itself and the back plate, which enables the engaging member to be pulled out from the engaging hole. This dynamic deformation capability allows the structure to transition from a tightly coupled state to an easily disengaged state without requiring tools.
Solution Approach 2:
The material properties of the frame body are selected to allow controlled deformation under applied force. By changing the physical state or shape of the frame body through deformation, the engagement between the engaging member and engaging hole can be broken. This parameter change enables the system to switch between a secure coupled state and a disengaged state.
2Ease of operation
If the frame is designed to be removable without tools for ease of assembly, then the ease of operation is improved, but the coupling strength may deteriorate
Solution Approach 1:
The frame body's deformability allows it to maintain structural integrity during assembly while enabling easy disassembly. During normal operation, the frame remains rigid and securely coupled. During disassembly, controlled deformation is applied to create a gap, allowing tool-free removal. This dynamic behavior ensures both strong coupling during use and easy disengagement when needed.
Solution Approach 2:
The frame body is designed with flexible or deformable characteristics, allowing it to bend or change shape under applied force. This flexibility enables the frame to be deformed sufficiently to create a gap between the frame and back plate, facilitating easy disengagement of the engaging member from the engaging hole without requiring tools.

AI summary
A coupling mechanism includes a back plate and a frame unit. The back plate is formed with at least one engaging hole. The frame unit has at least one frame body, and at least one engaging member extending from the at least one frame body, and engaging the at least one engaging hole for coupling fixedly the at least one frame body to the back plate. The at least one frame body is deformable for disengaging the at least one engaging member from the at least one engaging hole, thereby permitting removal of the at least one frame body from the back plate.
