Vehicle Interior Retaining Device with Adhesive Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding devices for vehicle interiors risk damaging vehicle walls due to low structural rigidity, as they require significant prestress to secure objects, which can deform the walls and compromise the hold.
Innovation Solution
A holding device with plate-shaped support members featuring a hook-and-loop fastener system that allows secure attachment without prestress, using flexible adhesive fastener mats and a conical plug-in socket to absorb transverse forces and accommodate uneven wall contours, ensuring stability and easy detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a retaining strut is tightened to secure objects, then the holding force is improved, but the vehicle walls may deform or be damaged due to low structural rigidity
Solution Approach 1:
The patent introduces adhesive fastener surfaces as an intermediary between the retaining strut and vehicle walls. These adhesive surfaces distribute the mounting forces over a larger area, preventing concentration of stress that would deform soft vehicle walls while maintaining secure attachment. The adhesive layer acts as a mediator that transfers loads without damaging the wall structure.
Solution Approach 2:
The patent changes the physical state and distribution of mounting forces by using adhesive bonding instead of mechanical fastening. The adhesive fastener surfaces transform point loads into distributed area loads, fundamentally changing how forces are transmitted to the vehicle walls and preventing deformation.
2Object-affected harmful factors
If adhesive fastener surfaces are used for mounting, then wall damage is prevented, but the fastening strength may be insufficient for heavy loads
Solution Approach 1:
The patent combines multiple fastening mechanisms into a single integrated system. Adhesive fastener surfaces are merged with mechanical interlocking elements (such as hooks, loops, or complementary geometric features) to create a hybrid mounting system that leverages both the distributed load distribution of adhesives and the high strength of mechanical engagement.
Solution Approach 2:
The mounting system uses composite construction, combining adhesive materials with mechanical fastening components. This composite approach allows the system to exhibit both the gentle, distributed attachment characteristics of adhesives and the high strength properties of mechanical fasteners, resolving the contradiction between wall protection and load-bearing capacity.
3Stability of the object's composition
If the rod structure is made rigid to maintain shape, then structural stability is improved, but adaptability to uneven wall contours is reduced
Solution Approach 1:
The patent divides the mounting system into separate functional segments: rigid structural components (rod, support members) maintain overall stability, while flexible adhesive layers and compliant mounting interfaces provide adaptation to surface irregularities. This segmentation allows each component to optimize its function without compromising the other.
Solution Approach 2:
The patent employs flexible adhesive fastener surfaces and thin compliant layers between rigid components. These flexible elements conform to uneven wall contours while the rigid rod structure maintains its structural integrity and load-bearing capability, resolving the contradiction between rigidity and adaptability.
4Object-affected harmful factors
If the support members are made large to distribute forces, then wall protection is improved, but the device complexity increases
Solution Approach 1:
The patent designs support members that serve multiple functions simultaneously: they provide structural support, distribute mounting forces over large areas to protect walls, and incorporate adhesive fastening surfaces for secure attachment. This multi-functionality eliminates the need for separate components for each function, reducing overall device complexity while achieving force distribution.

AI summary
A retaining device which can be fitted in a vehicle interior (1), in particular as part of a storage system, is proposed. Said retaining device contains at least one retaining strut (6) with a length-adjustable rod structure (13) and two plate-like supporting elements (14) attached to the end sides thereof. The supporting elements (14) can be fixed to the vehicle walls (7, 8) by a respective adhesive fastening device (45). This results in a secure support for the retaining struts (6) without it being necessary to brace the retaining struts (6) fixedly between the vehicle walls (7, 8).
