Casing Coupling Structure with Detachment Hole for Tool-Assisted Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coupling structures for electronic device casings require manual labor for assembly and are difficult to disassemble, making them inconvenient for repairs or recycling and vulnerable to theft due to secure fastening mechanisms.
Innovation Solution
A coupling structure featuring a first coupling element with a detachment hole and a second coupling element that can be disengaged using a detachment tool, allowing for easy separation of casing halves by inward bending of the second coupling element relative to the first, facilitated by hooks and hooking grooves for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If fastener screws are used for fastening the casing, then the casing is securely fastened, but manual labor is required during assembly and disassembly is difficult
Solution Approach 1:
The coupling element is divided into a first coupling element fixed to the first casing half and a second coupling element movable within the first coupling element. The second coupling element can be independently engaged and disengaged, allowing tool-free assembly and disassembly while maintaining secure fastening.
Solution Approach 2:
The second coupling element is designed to be movable relative to the first coupling element, transitioning between engaged and disengaged states. This dynamic structure allows the casing to be securely fastened during use but easily opened when needed, resolving the contradiction between strength and ease of operation.
2Reliability
If fastener strap means are used to prevent opening, then theft is prevented, but repair and recycling become inconvenient
Solution Approach 1:
The coupling structure includes a detachment hole that accepts a detachment tool, enabling the user to easily disengage the second coupling element from the first. This self-service mechanism allows quick opening for repair or recycling while maintaining secure fastening during normal use, resolving the contradiction between theft prevention and ease of repair.
3Strength
If manual fastening is used, then assembly security is maintained, but labor intensity increases
Solution Approach 1:
The second coupling element acts as an intermediary mechanism between the first coupling element and the user. It can be easily engaged and disengaged using a simple detachment tool through the detachment hole, eliminating the need for manual screw operations while maintaining secure assembly. This resolves the contradiction between assembly security and productivity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The coupling structure enables quick and convenient disengagement of casing halves, reducing manual labor and theft risks while maintaining security, and simplifying repair and recycling processes.
Implementation Method 1
pressing against the second coupling element with the detachment tool inserted along the detachment direction via the detachment hole in the first coupling element results in inward bending of the second coupling element with respect to the first coupling element

AI summary
A coupling structure for coupling first and second halves into a casing, includes a first coupling element projecting outward from an inner surface of the first casing half and formed with a detachment hole and a second coupling element projecting outward from an inner surface of the second casing half and for engaging with the first coupling element. Insertion of a detachment tool via an opening in the casing and the detachment hole to abut against the second coupling element results in inward bending of the second coupling element with respect to the first coupling element, thereby disengaging the second coupling element from the first coupling element, hence the first casing half disengages from the second casing half.
