Quick-Dismounting Housing Cover With Rotary Hook Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing housing designs for electronic products, such as all-in-one computers and sound boxes, require time-consuming screw dismounting and exertion to open and close side panels, especially in narrow spaces, making operations inconvenient.
Innovation Solution
A quick-dismounting housing structure featuring a base plate with a retaining portion, a covering plate with a switch recess, and a rotatable switch module with a hook piece and elastic element, allowing the covering plate to be easily locked or disengaged by moving the switch module, which includes a holding portion, hook piece, and elastic element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fix the cover to the housing, then the connection is strong and reliable, but the dismounting and fastening process becomes time-consuming and requires additional tools
Solution Approach 1:
The connection mechanism is segmented into modular components: a retaining portion on the housing, a switch module with hook piece on the cover, and an elastic element. This segmentation allows the cover to be quickly attached and detached without screws, resolving the contradiction between connection reliability and dismounting time.
Solution Approach 2:
The switch module is designed to be movable between locked and unlocked positions. The elastic element provides dynamic force to maintain engagement or release the hook piece from the retaining portion, enabling quick transitions between attached and detached states without requiring tools or excessive time.
2Device complexity
If a switch button is used for unlocking the side panel, then the dismounting structure is simplified, but the user needs to exert force to open the switch and remove the panel
Solution Approach 1:
The elastic element automatically provides the force needed to move the holding portion and disengage the hook piece from the retaining portion. When the user pulls the holding portion outward, the elastic element's restoring force assists in completing the unlocking action and returning the switch module to its original position, reducing the effort the user must exert.
3Device complexity
If the side panel moves laterally or outward for dismounting, then the locking mechanism is simplified, but the user must overcome resistance to move the panel
Solution Approach 1:
The hook piece acts as an intermediary between the cover and housing, providing a controlled engagement and disengagement mechanism. The elastic element serves as a mediator that manages the force interaction, storing energy during engagement and releasing it during disengagement, thereby reducing the force the user must directly apply to move the cover.
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
Enables direct and effortless opening and closing of the covering plate, reducing operational complexity and effort, with the elastic element aiding in returning the switch module to its original position and providing action and reaction forces for smooth operation.
Implementation Method 1
the elasticity of the elastic element of the instance disclosure not only helps the holding portion back to an original position, but also provides action and reaction force between the switch module and the retaining portion

AI summary
A housing having a quick-dismounting structure includes a base plate, a covering plate and a switch module. The base plate has a retaining portion. The covering plate has one side against the retaining portion and a switch recess corresponding to the side. The switch module is rotatably disposed in the switch recess and including a holding portion exposed outside the switch recess, a hooking board extended from the holding portion toward the matching board, and an elastic element. The hooking board has a fastening end faced the retaining portion. When the holding portion is moved, the hook piece shifts accordingly and the hooking end-portion is selectably hooked the retaining portion which then lock or disengage the covering plate, for dismounting the covering plate conveniently.
