Wall Mounting Structure for Suction and Adhesive Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mountings for vertical surfaces, particularly those using suction or adhesive methods, face issues when combined, as suction mountings require edge pressure and vacuum creation, while adhesive mountings need even load distribution to prevent premature debonding, and existing designs can lead to overloading and deformation.
Innovation Solution
A mounting system with a fixing member, a rotatable member, and an intermediate member, where the intermediate member has a formation for pressing the fixing member within its outer periphery to distribute pressure evenly and includes a stop to limit movement and prevent deformation, and extends beyond the adhesive layer for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the intermediate member presses the fixing member at the outer periphery to create suction, then the suction force is improved, but the adhesive layer becomes overloaded and debonds prematurely
Solution Approach 1:
The intermediate member features a dual-zone pressing structure: an first formation that presses at the outer periphery to generate suction force, and a second formation that presses at an inner position within the periphery to distribute load away from the adhesive layer edges. This local differentiation allows simultaneous optimization of suction performance and adhesive bonding reliability.
2Force
If the rotatable member is tightened to increase suction, then the suction effectiveness is improved, but the fixing member becomes deformed
Solution Approach 1:
The intermediate member's dual formation structure creates localized pressure zones that prevent excessive deformation. The first formation at the periphery allows sufficient tightening for suction effectiveness, while the second formation at the inner position acts as a mechanical stop to prevent over-tightening and deformation of the fixing member.
3Reliability
If the adhesive layer is made soft to improve bonding, then the bonding capability is improved, but the adhesive layer becomes vulnerable to damage
Solution Approach 1:
The intermediate member extends beyond the periphery of the adhesive layer, creating a protective overhang that shields the soft adhesive layer from external mechanical damage during cleaning or handling. This beforehand protection allows the adhesive to remain soft for optimal bonding without sacrificing durability.
4Adaptability or versatility
If a single intermediate member design is used for both suction and adhesive fixing, then the inventory is simplified, but the load distribution is suboptimal for adhesive fixing
Solution Approach 1:
The intermediate member incorporates two distinct formations with different functions: the first formation at the periphery optimized for suction engagement, and the second formation at an inner position optimized for even load distribution across the adhesive layer. This allows a single component design to achieve optimal performance for both suction and adhesive fixing methods.

Function Achieved in This Case
This solution allows for flexible use with either suction or adhesive fixing, preventing premature debonding and deformation, while protecting the adhesive layer from damage, enhancing the mounting system's reliability and versatility.
Implementation Method 1
a fixing member (1), having an adhesive layer (4) for contacting and bonding to a surface
Implementation Method 2
it is known to use suction mountings (for example as shown in GB 2426784), in which a suction pad is drawn away from the wall to create a partial vacuum which fixes the mounting to the wall

AI summary
The present invention provides a mounting for attachment to a substantially vertical surface, comprising a fixing member (1), having an adhesive layer (4) for contacting and bonding to a surface, a rotatable member (10) comprising a substantially helical or wedge shaped surface (22) engaged with a corresponding substantially helical or wedge shape surface (2) of the fixing member (1), and an intermediate member (5), gripped between the rotatable member (10) and the fixing member (1), in use, wherein the intermediate member (5) has a formation (15) for pressing the fixing member (1) at a position (3) within the outer periphery (23) of the fixing member, so that the fixing member (1) and adhesive layer (4) are not deformed excessively. A stop (25) in the form of a helical spring may be provided for limiting the movement of the fixing member (1) with respect to the rotatable member (10) so that the fixing member is substantially not deformed by the movement of the fixing member with respect to the rotatable member. The periphery (24) of the intermediate member may extend outside the periphery of the adhesive layer (4) in a plane parallel to the surface, in use, to protect it.
