Housing Assembly Quick-Release Mechanism for Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional housing assemblies for electronic devices are time-consuming to assemble and disassemble due to reliance on screws, which can loosen or get damaged, and existing solutions do not allow for quick and easy disengagement or replacement of housing parts.
Innovation Solution
A housing assembly design featuring a first and second housing with positioning holes, engaging devices with resilient members, and an operation device that includes release members and a link mechanism to facilitate easy disengagement by shifting the operation member, allowing for quick removal of both housings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple screws are used to connect housing parts, then the connection strength is improved, but the assembly time increases and the reliability decreases due to screw loosening or damage
Solution Approach 1:
The housing connection system is segmented into multiple engaging devices, each with independent engaging members that can be actuated separately. This allows the housing to be divided into modular sections that can be assembled or disassembled independently, reducing overall assembly time while maintaining strong connections through distributed engagement points
Solution Approach 2:
The engaging members are designed with resilient properties, allowing them to dynamically adjust during assembly and disassembly. The resilient engaging members can be elastically deformed to engage with positioning holes and return to their original shape to maintain constant connection force, enabling quick assembly without screws while preserving connection strength
2Strength
If multiple screws are used to connect housing parts, then the connection strength is improved, but the reliability worsens due to screw loosening or threaded hole damage
Solution Approach 1:
The screw fastening mechanism is completely extracted from the housing connection system. Instead of using screws that can loosen or damage threaded holes, the patent employs resilient engaging members that directly engage with positioning holes through elastic deformation, eliminating the reliability issues associated with screw-based connections while maintaining adequate connection strength
Solution Approach 2:
The resilient engaging members are self-actuating and self-locking. When engaged with positioning holes, they automatically exert elastic force to maintain connection without requiring additional fastening elements. The resilient nature provides self-compensation for misalignment and self-locking against disengagement, improving reliability without sacrificing connection strength
3Ease of operation
If a slidable element with notches is used to engage housing portions, then the assembly ease is improved, but the disengagement speed worsens as housings must be completely separated
Solution Approach 1:
The connection system is segmented into multiple independent engaging devices distributed along the housing. Each engaging device can be actuated independently through the operation device, allowing partial disengagement of housing sections. This segmentation enables quick removal of specific housing portions without requiring complete disassembly of the entire housing assembly
Solution Approach 2:
The engaging members are designed with resilient properties that allow dynamic engagement and disengagement. The resilient members can be easily deformed to release from positioning holes when actuated, enabling rapid disengagement. The elastic energy stored in the resilient members assists the disengagement process, reducing the force and time required compared to rigid connection systems
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 rapid and efficient disassembly and replacement of housing components, improving assembly quality and user convenience by using a mechanism that securely engages and disengages the housings without the need for screws.
Implementation Method 1
A first resilient member is applied to the first engaging member so that the first engaging member is orientated toward one of the first positioning holes of the first housing. A second resilient member is applied to the second engaging member so that the second engaging member is orientated toward one of the second positioning holes of the second housing.
Implementation Method 2
A link is connected to the assembly unit and connected with the first and second release members. An operation member is connected to the link so as to move the link and the first and second release members. When the operation member is shifted toward the first direction, the first and second release members are moved by the link, and the first engaging member of each engaging device is disengaged from the first positioning holes of the first housing
