Pre-Assembled Screw Retention Structure for Repeated Display Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Screws in existing assemblies require separate packaging and transportation, leading to additional costs and potential loss, and pre-assembled screws are difficult to repeatedly assemble due to limited mounting space and detachment issues.
Innovation Solution
A structure with a screw, including a limiting structure, assembly member, and elastic member, where the screw is pre-assembled and can return to its original position after detachment, using an elastic member to push the screw back into place, allowing for repeated assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a screw is pre-assembled, then assembly efficiency is improved and separate packaging is eliminated, but the screw cannot return to its original position after detachment due to limited mounting space
Solution Approach 1:
The screw is nested within a cavity formed by the first and second connecting portions, allowing it to be stored in place and return to its original position after detachment. The elastic component provides a restoring force that pushes the screw back into the cavity, enabling repeated assembly operations within the limited mounting space.
Solution Approach 2:
The elastic component introduces dynamic behavior to the screw assembly system. The elastic force dynamically pushes the screw toward the cavity, allowing the screw to automatically return to its storage position after being detached, thus enabling repeated assembly without requiring additional mounting space.
2Ease of manufacture
If a screw is kept separate, then storage and transportation are simpler, but additional packaging costs are incurred and the screw is easy to lose
Solution Approach 1:
The screw is merged with the connecting structure by being stored within the cavity formed by the first and second connecting portions. This integration eliminates the need for separate packaging, reduces the risk of loss, and maintains simplicity in storage and transportation while improving reliability.
Solution Approach 2:
The cavity structure serves multiple functions: it stores the screw, provides structural connection between components, and prevents the screw from being lost. This multi-functionality eliminates the need for separate packaging while ensuring screw retention.
3Volume of moving object
If mounting space is limited, then device compactness is improved, but pre-assembled screws cannot return to their original position after detachment
Solution Approach 1:
The screw is nested within the cavity formed by the connecting portions, allowing it to be stored in the limited mounting space. The elastic component ensures the screw returns to this nested position after detachment, enabling repeated assembly without requiring additional space.
Solution Approach 2:
The elastic component provides a dynamic restoring force that pushes the screw back into the cavity within the limited mounting space, enabling the screw to return to its original position after detachment and facilitating repeated assembly operations.
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 solution ensures stable and efficient assembly by preventing the screw from falling off and facilitating repeated assembly, reducing costs and improving assembly efficiency by eliminating the need for separate screw packaging and handling.
Implementation Method 1
an elastic member, wherein one end of the elastic member is configured to abut against the abutting step and the other end of the elastic member is configured to abut against the screw
