Backplane Clamping Member with Breakable Structure for Frame Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spliced frame structures in display devices are difficult to disassemble due to non-reversible metal buckles, making it challenging to separate the backplane from the middle frame once integrated.
Innovation Solution
Incorporating a breakable structure within the clamping member of the backplane's skirt, allowing for separation from the middle frame when an external force is applied, utilizing a clamping tongue structure that breaks free from a groove and elastic sheets for secure engagement and disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a metal buckle is designed for easy mounting, then the ease of operation is improved, but the reliability of permanent connection deteriorates
Solution Approach 1:
The clamping member transitions from a static permanent connection to a dynamic reversible connection. The elastic sheet allows the clamping member to be mounted by elastic deformation and dismounted by breaking the breakable structure, enabling the connection state to change from fixed to reversible based on operational needs.
Solution Approach 2:
The clamping member is segmented into distinct functional parts: an elastic sheet for reversible mounting, a breakable structure for controlled dismounting, and a clamping portion for securing. This segmentation allows each part to perform its specific function independently, resolving the contradiction between easy mounting and permanent connection.
2Strength
If a metal buckle provides strong clamping force, then the strength of connection is improved, but the ease of dismounting deteriorates
Solution Approach 1:
The strength of the connection is changed through parameter modification. The breakable structure is designed with specific material properties and geometric parameters that allow it to maintain strong clamping force during normal operation but break under controlled external force during dismounting, enabling transition from strong connection to easy dismounting.
Solution Approach 2:
The breakable structure functions as a disposable component that is intentionally designed to break for dismounting. This sacrificial element provides strong connection during use but allows easy dismounting when needed, embodying the principle of using a consumable part to achieve reversible connection.
3Ease of operation
If the clamping member is designed for easy separation, then the ease of operation is improved, but the reliability of connection deteriorates
Solution Approach 1:
The connection reliability is made dynamic rather than static. The elastic sheet provides reliable connection during normal operation through elastic deformation, while the breakable structure enables easy separation when needed. The system transitions from a reliably connected state to an easily separable state based on operational requirements.
Solution Approach 2:
The breakable structure acts as an intermediary element between the elastic sheet and the external environment. It mediates between the need for reliable connection (providing strong clamping force) and the need for easy separation (allowing controlled breaking), enabling the system to achieve both contradictory requirements through this intermediate component.
