Adhesive Wall Mounting with Spring Stop for Debonding Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting systems for vertical surfaces face challenges in using intermediate members that can be selectively used with either suction or adhesive fixing, as suction mountings require a different force pattern than adhesive mountings, leading to potential debonding issues when excessive tension is applied.
Innovation Solution
A mounting system with a fixing member having an adhesive layer and a rotatable member with a helical or wedge-shaped surface, where an intermediate member is gripped between them, and a coil spring stop limits movement to prevent deformation, allowing for balanced pressure distribution and compatibility with both suction and adhesive fixings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a rotatable member with helical surface is used to fix the intermediate member to the fixing member, then the suction force is increased, but the adhesive layer may be overloaded and debond prematurely
Solution Approach 1:
The patent introduces a stop mechanism that changes the mechanical parameter of tension force applied to the adhesive layer. By limiting the movement of the rotatable member, the stop prevents excessive tension from being applied to the adhesive layer, thereby maintaining reliable bonding while still allowing sufficient tension for suction force generation.
2Force
If the rotatable member is tightened too much to increase suction, then the adhesive layer adjacent to the helical surface becomes overloaded, but loosening it reduces suction effectiveness
Solution Approach 1:
The stop mechanism acts as a pre-established protective element that cushions against excessive tension. By being in place before the tightening process, it prevents the harmful condition of overloaded adhesive layer from occurring in the first place, allowing the user to tighten the rotatable member confidently without risking premature debonding.
3Adaptability or versatility
If an intermediate member designed for suction mounting is used with adhesive fixing, then the force pattern is mismatched causing edge pressing only, but modifying it for adhesive may compromise suction functionality
Solution Approach 1:
The intermediate member is designed with a uniform pressure distribution feature that makes it universally compatible with both adhesive fixing and suction mounting. This design allows the same intermediate member to work reliably with either fixing method, eliminating the need for different designs while maintaining bonding reliability through balanced pressure distribution across the adhesive layer.

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 system ensures stable attachment to vertical surfaces by preventing deformation and ensuring balanced pressure distribution, allowing for the use of either suction or adhesive fixing without premature debonding, and can be reused with suction members.
Implementation Method 1
a stop is provided for limiting the movement of the fixing member with respect to the rotatable member so that the fixing member is substantially not deformed by the movement of the fixing member with respect to the rotatable member, and wherein the stop member comprises a coil spring

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.
