Resilient Hook Casing Coupling for Screwless Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coupling structures for electronic device casings that use fastener screws for assembly are difficult to disassemble, leading to labor inefficiencies and potential damage to internal components during repair or replacement.
Innovation Solution
A coupling structure featuring resilient engaging hooks and an L-shaped pushing element allows for easy disengagement of casing parts without screws, using a detachment hole and guiding slots for manual disassembly, enabling the second casing part to be removed without damaging internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If fastener screws are used to fasten the upper and lower casing parts, then the casing structure is strong and secure, but the disassembly process becomes difficult and time-consuming
Solution Approach 1:
The coupling structure is divided into multiple functional elements: resilient engaging hooks for secure attachment, rigid engaging hooks for structural support, and an L-shaped pushing element for controlled disassembly. This segmentation allows each component to perform its specific function optimally while enabling easy separation when needed.
Solution Approach 2:
The coupling structure transitions from a static fastened state to a dynamic disassembly process. The resilient engaging hooks can deform elastically under the action of the pushing element, allowing the casing parts to be separated through controlled movement rather than requiring forceful removal of fixed fasteners.
2Reliability
If conventional fastening methods are used, then the casing is securely assembled, but labor waste occurs during assembly and disassembly operations
Solution Approach 1:
The coupling structure performs self-assembly and self-disassembly functions. The resilient engaging hooks automatically engage with the rigid engaging hooks to secure the casing parts, and the same structure enables easy separation through the pushing element without requiring external fastening tools or complex procedures.
3Ease of repair
If the casing is made easily detachable for repair purposes, then maintenance becomes convenient, but the structural integrity and security of the casing may be compromised
Solution Approach 1:
Different parts of the coupling structure have different properties: the resilient engaging hooks provide flexible, reversible connection for easy maintenance, while the rigid engaging hooks provide strong, stable support for structural integrity. The L-shaped pushing element provides a localized interface for controlled disassembly without affecting the overall structural strength when assembled.

Function Achieved in This Case
Enables easy and efficient disassembly of electronic device casings without the need for fastener screws, reducing labor and minimizing risk to internal components, while maintaining structural integrity.
Implementation Method 1
manually leftwise movement of the pushing element in the left direction along a detachment path results in simultaneous bending of the resilient engaging hook in the left direction so as to disengage the rigid engaging hook from the second engaging groove

AI summary
A coupling structure couples first and second casing parts together. The first casing part is formed with a detachment hole. The coupling structure includes one resilient engaging hook projecting from the first casing part and a coupling member disposed between the first and second casing parts and formed with first and second engaging grooves. The resilient engaging hook hooks the first engaging groove in a right direction. The coupling member has a pushing element tending toward the detachment hole. One rigid engaging hook projects from the second casing part and engaging the second engaging groove in a left direction. Manually leftwise movement of the pushing element in the left direction results in simultaneous bending of the resilient engaging hook in the left direction so as to disengage the rigid engaging hook from the second engaging groove, thereby permitting removal of the second casing part from the first casing part.
