Holding, supporting or seating arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding, support, and seat arrangements in sanitary areas, particularly for individuals with disabilities or those using wheelchairs, face challenges in securely attaching and pivoting devices without visible fasteners or sharp edges, and in distributing loads effectively to prevent joint overload.
Innovation Solution
A swivel joint bearing system with two parallel bearing plates forming an 'L' or 'T' configuration, guided through slots in a wall cover, and a support element to distribute weight, ensuring secure attachment and load distribution while hiding fasteners and preventing sharp edges, using a spring-elastic mounting to facilitate smooth pivoting and secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bearing plates are directly attached to the wall structure, then the attachment is secure and reliable, but the fasteners and sharp edges become visible and accessible, compromising aesthetics and safety
Solution Approach 1:
A wall cover is introduced as an intermediary element between the bearing plates and the wall structure. The bearing plates are attached to the wall cover instead of directly to the wall, and the wall cover is then fixed to the wall structure. This intermediary layer hides the fasteners and sharp edges of the bearing plates, eliminating the aesthetic and safety issues while maintaining the secure attachment through the wall cover's connection system
2Device complexity
If the swivel joint is mounted with simple bearing plates, then the device complexity is low, but the load distribution is insufficient, risking joint overload
Solution Approach 1:
The bearing structure is segmented into two parallel bearing plates instead of a single plate. These two plates are arranged parallel to each other and connected to the swivel joint, creating a distributed load path. The segmentation allows the load to be spread across multiple contact points and a larger surface area, improving load distribution and joint capacity while maintaining relatively simple individual plate designs
3Manufacturing precision
If the bearing plates are guided through slots in the wall cover, then the positioning precision and load guidance are improved, but the device complexity increases
Solution Approach 1:
Slots are introduced as intermediary guiding elements between the bearing plates and the wall cover. The bearing plates are guided through these slots during assembly and operation, providing precise positioning and load guidance. The slots act as mediators that constrain the movement of the bearing plates to the desired path, improving positioning precision and load distribution while the modular slot design keeps the complexity manageable

Function Achieved in This Case
The solution provides a secure, load-distributing, and aesthetically pleasing attachment system for holding, support, or seat devices in sanitary areas, allowing for safe and efficient use by individuals with mobility issues, while protecting the joint from overload and maintaining a clean appearance.
Implementation Method 1
a support element which is spring-elastic in relation to the rotatable part and/or the bearing plate is stored in that this support element is pressed against the bearing plate or the rotatable part

AI summary
The present invention relates to a bearing (1) for a swivel joint (2) for attaching a holding, supporting or seat device (3) to a structure in the sanitary area, comprising two parallel bearing plates (1a, 1b), each of the bearing plates ( 1a, 1b) has at least one fastening surface (1ca; 1cb). This bearing is designed according to the present invention in that the pivot joint (2) is mounted via the two parallel bearing plates (1a, 1b), each of the bearing plates (1a; 1b) being connected to the at least one fastening surface (1ca; 1cb) assigned to it. forms an "L". The two bearing plates (1a, 1b) are guided through slots (4a, 4b) in a wall cover (4) that correspond to the bearing plates in such a way that the fastening surfaces (1ca, 1cb) of the respective "L" are on the side of the wall cover facing the structure (4) located. The rotatable part (2a) of the swivel joint (2) is arranged between the two bearing plates (1a, 1b). The two L-shaped parts can also be connected to form a single U-shaped part.
