Lightweight Junction Box With Folding Wings for Secure Wall Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lightweight boxes for building technology installations, particularly electrical devices, face challenges in maximizing internal volume while adhering to strict installation dimensions, and their complex assembly processes lead to increased costs and material requirements.
Innovation Solution
A lightweight box design featuring a can body with a support flange and wing structure that allows for secure attachment to a building wall without tilting feet, simplifying assembly and reducing material needs by using a wing that deflects radially upon screwing, thereby eliminating the need for additional components and steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate screw channels and recesses for tilting feet are provided, then the lightweight box can be securely attached to the building wall, but the internal volume of the box body is reduced
Solution Approach 1:
The patent combines the attachment function and the support function into a single integrated wing structure. The wing serves both as a support element that presses against the building wall and as a structural component that eliminates the need for separate screw channels and recesses, thereby maximizing internal volume while maintaining secure attachment
Solution Approach 2:
The wing structure performs multiple functions simultaneously: it provides mechanical support, enables secure attachment to the building wall, and serves as a structural element that eliminates the need for additional components. This multi-functionality resolves the contradiction by achieving secure attachment without sacrificing internal volume
2Reliability
If tilting feet and associated screws are used, then the lightweight box can be securely fixed in the building wall, but additional components and work steps are required, increasing costs
Solution Approach 1:
The patent merges the functions of tilting feet and attachment screws into a single wing structure that is integrated with the box body. This eliminates the need for separate components and reduces assembly complexity while maintaining secure attachment to the building wall
Solution Approach 2:
The invention extracts and eliminates the unnecessary tilting feet and associated screws from the design, retaining only the essential attachment function through the simplified wing structure. This reduces component count and assembly steps while achieving the same attachment security
3Volume of stationary object
If the box body circumference is expanded to increase internal volume, then more electronics can be accommodated, but compliance with installation dimension standards becomes difficult
Solution Approach 1:
The patent utilizes the wall thickness dimension by extending the wing structure into the building wall recess. This allows the box body to maintain standard external dimensions for compliance while the wing structure provides additional attachment capability and the box body interior maximizes internal volume for accommodating electronics
