Push-Button Housing Lock for Tool-Free Electronic Device Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Minicomputers require tools for disassembly, causing inconvenience when users need to perform hardware upgrades or cleaning, as traditional screw-based housings are not easily accessible without tools.
Innovation Solution
A housing structure with a push-button locking device and elastic member that allows the cover to be rotated upward without tools, using a push rod to disengage the hook and elastic force to lift the cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw-based locking mechanism is used to secure the housing, then the structural strength and reliability are improved, but the ease of operation deteriorates because users require special tools for disassembly
Solution Approach 1:
The locking device enables users to disassemble the housing themselves without requiring external tools. The push button mechanism allows the user to directly actuate the locking device, which automatically releases the hook from the limit hook, enabling tool-free disassembly while maintaining secure locking during normal operation
Solution Approach 2:
The locking device transitions from a static screw-based mechanism to a dynamic push-button mechanism. The push rod and elastic member create a spring-loaded system that can be easily actuated by the user, allowing the hook to be engaged or disengaged from the limit hook through simple button pressing, thereby improving ease of operation while maintaining reliability
2Ease of operation
If a push-button locking device with elastic member is used, then the ease of operation is improved by enabling tool-free disassembly, but the device complexity increases due to additional components
Solution Approach 1:
The locking device merges multiple functions into a single integrated mechanism. The push button, push rod, elastic member, and hook work together as one unified system that combines locking, unlocking, and lifting functions. This integration reduces the need for separate components and mechanisms, thereby limiting the increase in device complexity while achieving tool-free operation
3Reliability
If the hook is designed to buckle the limit hook for secure locking, then the reliability is improved, but the ease of operation worsens because the hook must be manually disengaged
Solution Approach 1:
The locking device enables self-service unlocking where the user's action on the push button directly causes the hook to disengage from the limit hook. The elastic member stores energy that automatically assists in releasing the hook, eliminating the need for manual manipulation or external tools to break the locking engagement
Solution Approach 2:
The locking mechanism uses dynamic elements including the movable push rod and elastic member to create a spring-loaded system. When the push button is pressed, the push rod moves dynamically to withdraw the hook from the limit hook, and the elastic member's stored energy provides the force needed to overcome the locking engagement, making unlocking easy while maintaining secure locking during normal use
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 tool-free disassembly of the housing, enhancing convenience for users performing upgrades or cleaning, addressing the limitations of traditional screw-based designs.
Implementation Method 1
the elastic member pushes the electronic device by elasticity to make the cover to rotate upward

AI summary
A housing structure of electronic device, which accommodates an electronic device. The housing structure of the electronic device includes a housing, a cover, a locking device and an elastic member. The housing includes a limit hook, and the locking device includes a push button and a push rod. By pushing the push button and driving the push rod to slide, the push rod drives the hook that contained in it to leave the limit hook and the elastic member elastically pushes the electronic device to rotate the cover upward, thereby solving the inconvenience of the conventional shell structure that requires the use of tools to disassemble.
