Wall Casing Fastening Mechanism for One-Sided Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening mechanisms for plug-in unit assemblies require work on both sides of the wall and use loose accessories, making the mounting process complicated and time-consuming.
Innovation Solution
A fastening mechanism featuring a rotating and longitudinally movable pressing element that allows the casing to be secured from one side of the wall, with integrated accessories to prevent loss and simplify the mounting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate fixing clips and screws are used to fasten the casing, then the fastening reliability is improved, but the device complexity and ease of operation deteriorate due to multiple loose accessories
Solution Approach 1:
The patent combines multiple separate fastening accessories (fixing clips and screws) into an integrated fastening mechanism that is part of the casing structure. The pressing element and collar work together as a unified system, eliminating the need for separate loose accessories and simplifying the mounting process while maintaining fastening reliability.
Solution Approach 2:
The integrated fastening mechanism serves multiple functions: the collar provides both structural support and fastening attachment points, while the pressing element performs both positioning and securing functions. This multi-functionality reduces the number of separate components needed and simplifies the overall mounting operation.
2Reliability
If separate fixing clips and screws are used, then the fastening reliability is improved, but the productivity deteriorates due to slower mounting process
Solution Approach 1:
By integrating the fastening mechanism into the casing structure, the patent reduces the number of separate assembly steps. The pressing element and collar work together as a pre-integrated system, allowing for faster installation while maintaining secure fastening through the coordinated action of these components.
3Reliability
If the casing is fastened from both sides of the wall, then the fastening reliability is improved, but the ease of operation deteriorates due to requiring work on both sides
Solution Approach 1:
The patent extracts the fastening function from requiring access to both sides of the wall and concentrates it in the pressing element, which can be operated from the front side only. The pressing element is designed to engage with the collar and secure the casing while applying force through the wall thickness, eliminating the need for backside access.
4Adaptability or versatility
If loose accessories are used for mounting, then the adaptability is improved, but the loss of substance increases due to accessories coming loose and being lost
Solution Approach 1:
By integrating the fastening mechanism components into the casing structure, the patent eliminates the problem of loose accessories being lost. The pressing element and collar are designed to work together as a unified system where components remain attached to the casing throughout the mounting process and do not become loose or misplaced.

AI summary
A fastening mechanism for fastening a casing (2) into an opening in a wall (4), the mechanism comprising a collar element (6) fastened to the casing and arranged to be in contact with a first side of the wall, a pressing element (8) arranged to be in contact with a second side of the wall, the collar element and the pressing element being arranged to co-operate to direct a pressing force towards the w all, and a screw means (10) arranged to move the pressing element. The pressing element is arranged to rotate between a normal position and a mounting position; in the normal position the pressing element is capable of coming into contact with the second side of the wall to achieve a force keeping the casing (2) in place and in the mounting position it allows the casing to be pushed into the final mounting depth.
