Storage device and system comprising a storage device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage devices for room corners, particularly in wet rooms, damage tiles and allow moisture penetration when installed using mechanical fixing elements, and removal often leaves residue or damages tiles when using adhesives.
Innovation Solution
A flat storage device with fixing sections that insert into the narrow gap between tiles, using joint compound for secure attachment without mechanical intervention, allowing for residue-free removal and maintenance access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mechanical fixing elements (screws, dowels) are used to attach the storage device, then the storage device can be securely fixed in the corner of the room, but the tiles on the side walls are damaged and moisture can penetrate the side wall
Solution Approach 1:
The invention uses a chemical adhesive as an intermediary substance between the storage device and the tile surface. This adhesive mediator transfers the fixing force without requiring mechanical penetration of the tiles, thus avoiding damage to the tile structure and preventing moisture penetration pathways that would be created by drilling holes.
Solution Approach 2:
The invention replaces the mechanical fixing system (screws and dowels that physically penetrate the tiles) with a chemical bonding system (adhesive). This substitution eliminates the need for mechanical intervention in the tile structure, preserving the integrity of the tiles and their water-repellent properties while still achieving secure fixation.
2Object-affected harmful factors
If chemical adhesives are used to mount the storage device, then damage to the side walls from drilling is avoided, but residue-free removal is still only possible to a limited extent since removing adhesive residue usually damages the tile surface
Solution Approach 1:
The invention changes the parameters of the adhesive used - specifically selecting an adhesive with controlled bonding strength that provides sufficient fixation during use but allows for clean removal later. The adhesive formulation is optimized to balance initial bonding strength with removable properties, enabling residue-free removal without damaging the tile surface.
Solution Approach 2:
The adhesive exhibits dynamic properties where its bonding characteristics change over time or under different conditions. The adhesive provides strong initial bonding for secure mounting, but its bonding strength can be reduced or modified to allow for clean removal, thus adapting to different operational phases (installation vs. removal).
3Reliability
If drilling is performed to install mechanical fixing elements, then secure fixation is achieved, but the water-repellent intermediate layers of the wet room are penetrated, allowing moisture to penetrate the side wall
Solution Approach 1:
The invention replaces the mechanical penetration method (drilling through tiles and intermediate layers) with a chemical bonding method. The adhesive bonds to the surface of the tiles without penetrating the water-repellent intermediate layers, thus maintaining the moisture barrier integrity while still achieving reliable fixation of the storage device.
Solution Approach 2:
The chemical adhesive serves as an intermediary that transfers loads and secures the storage device without creating direct mechanical pathways through the moisture barrier. This intermediary bonding method preserves the continuity of the water-repellent layers, preventing moisture penetration and subsequent mold growth.
