Auxiliary Mounting Structure for Stable Wall-Hole Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall-mounted devices are prone to falling due to unstable support, as they rely solely on a rod through a wall mounting hole, which cannot provide sufficient stability against external forces like earthquakes or accidental impacts.
Innovation Solution
An auxiliary mounting device with a first and second engaging element and a connecting mechanism that divides a housing hole into an installing space and a constricting space, allowing the engaging regions to expand and change the constricting gap width, securely fixing a mounting member within the constricting space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rod is used to pass through a wall mounting hole for installation, then the device can be mounted on the wall, but the device is prone to fall off when shaken by external forces due to insufficient stability
Solution Approach 1:
The mounting device is segmented into multiple functional components: a housing with mounting hole, a rod receiving structure, and an auxiliary mounting device comprising first and second engaging elements. This segmentation allows each component to perform its specific function - the housing provides structural support, the rod receiving structure enables wall mounting, and the auxiliary engaging elements provide additional stabilization, thereby resolving the contradiction between mounting reliability and structural complexity
Solution Approach 2:
The auxiliary mounting device acts as an intermediary mechanism between the housing and the rod. The first engaging element with first engaging region and the second engaging element with second engaging region create constricting spaces that interact with the rod, providing additional stabilization without directly modifying the rod or housing structures, thus improving reliability while maintaining relatively simple overall structure
2Adaptability or versatility
If the engaging regions are expanded in opposite directions due to external force, then the constricting gap width changes to accommodate the mounting member, but the structure must be flexible enough to deform
Solution Approach 1:
The first engaging element and second engaging element are designed with dynamic characteristics that allow them to expand in opposite directions when external forces are applied. This dynamic behavior enables the constricting gap width to change adaptively - narrowing to constrain the mounting member during installation, then expanding to accommodate thermal expansion or external forces, thereby resolving the contradiction between adaptability and structural strength
Solution Approach 2:
The width of the constricting gap is designed as a variable parameter rather than a fixed dimension. The gap width can change from a first width (when engaging elements are in initial position) to a second width (when engaging elements expand due to external force), allowing the structure to adapt to different mounting conditions and external forces while maintaining sufficient structural strength through controlled deformation

AI summary
An auxiliary mounting device is configured for coupling to a housing and includes a first engaging element, a second engaging element and a connecting mechanism. The first engaging element has a first engaging region. The second engaging element corresponds to the first engaging element and has a second engaging region. The connecting mechanism is connected to the first engaging element and the second engaging element and configured for being detachably fixed on a surface of the housing. There is a constricting gap between the first engaging region and the second engaging region, and the first engaging region and the second engaging region divide a hole of the housing into an installing space and a constricting space.
