Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding devices for adhesive attachment to surfaces face challenges with high tightening and removal torques, which can damage the adhesive bond, especially when using threaded screws or nuts, and require drilling holes in walls for installation, causing optical impairments on tiled or newly renovated surfaces.
Innovation Solution
A holding device with an elastic fastening element that can be easily pushed onto or removed from a threaded bolt, featuring a helical rib profile and made of thermoplastic elastomers, allowing for simple assembly and limited torque application, thus protecting the adhesive connection and reducing the need for drilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a threaded screw or nut is used to fix an object to the holding device, then a secure fastening connection is achieved, but high tightening and removal torques are required which can damage the adhesive bond
Solution Approach 1:
The fastening system is divided into two independent parts: the threaded bolt integrated into the holding body and the separate fastening element. This segmentation allows the fastening element to be pushed onto the bolt in a linear motion rather than screwed on, eliminating high torque requirements while maintaining secure fastening connection.
Solution Approach 2:
Instead of screwing the fastening element onto the threaded bolt (rotational motion), the invention inverts the approach by pushing the fastening element linearly onto the bolt. The threaded bolt serves as a guide and positioning element rather than requiring rotational engagement, thus avoiding torque transmission to the adhesive bond.
2Reliability
If a threaded screw or nut is used for fastening, then reliable object fixation is achieved, but the assembly and disassembly process requires significant time and effort
Solution Approach 1:
The invention inverts the traditional screwing operation by using linear pushing motion instead of rotational motion. The fastening element is simply pushed onto the threaded bolt until it engages, and removed by pulling it off linearly. This eliminates the multiple turns required for screwing, dramatically reducing assembly and disassembly time while maintaining reliable object fixation.
Solution Approach 2:
The fastening element skips the time-consuming rotational screwing process and transitions directly onto the threaded bolt in a single linear pushing motion. This 'rushing through' of the fastening operation achieves reliable fixation in seconds rather than requiring multiple rotational cycles.
3Strength
If conventional holding devices are attached to walls using drilling, then secure mounting is achieved, but optical impairments occur on tiled or freshly renovated surfaces
Solution Approach 1:
The invention replaces the mechanical drilling and screwing system with an adhesive bonding system. The holding body is attached to the surface using adhesive strips that distribute loads over a larger area without creating holes or visible damage. This substitution eliminates optical impairments on tiled or freshly renovated surfaces while maintaining secure mounting through the combined adhesive and threaded bolt system.
Applied Scientific Principles
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 solution enables quick and easy fixation of objects with reduced force and time, limits torsional stresses on the adhesive bond, and prevents damage to surfaces by minimizing the forces applied during assembly and disassembly.
Implementation Method 1
the fastening element is elastic at least in the area of the opening, so that the fastening element can be provided with a contour in the area of the opening, which engages in the thread of the threaded bolt when screwing on and off and thus a form-fitting connection forms, while this deforms when plugging and unplugging using their elasticity so far that it slides over the thread of the threaded bolt
