Modular seating apparatus and corresponding systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional transfer benches lack customization options and interfere with shower curtains, causing instability and water leakage during use by individuals who require assistance with bathing.
Innovation Solution
A modular seating apparatus comprising a detachable bench and seat configuration, where the bench can be separated from the seat to allow for shower curtain closure, and reattached for user egress, made from durable materials like polyurethane and steel, with adjustable legs and drainage features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional transfer bench straddles the edge of the tub, then the user can slide from wheelchair into the tub, but the bench interferes with the shower curtain causing instability and water leakage
Solution Approach 1:
The transfer bench is divided into two separate components: a tub-side seat and a floor-side bench. These segments can be attached together for transfer operations or separated to allow shower curtain closure, eliminating the interference problem while maintaining transfer functionality.
Solution Approach 2:
The system transitions from a static traditional bench to a dynamic modular system where components can be attached and detached. This allows the configuration to change based on operational needs: attached during transfer, separated during showering to ensure stability and prevent water leakage.
2Adaptability or versatility
If a traditional transfer bench is used, then the user can access the tub, but the design lacks customization options for personal needs
Solution Approach 1:
The transfer system is segmented into multiple independent components (tub-side seat, floor-side bench, connecting mechanism) that can be configured in different arrangements. This segmentation enables customization for various user needs while the standardized connection interfaces keep the system manageable.
Solution Approach 2:
The modular components are designed with universal connection interfaces that allow them to be attached in different configurations. The same basic components can serve multiple functions: attached for transfer, separated for showering, or configured at different distances from the tub edge to accommodate various user requirements.
3Strength
If the bench is made from durable materials like polyurethane and steel, then the device gains strength and stability, but the device complexity increases
Solution Approach 1:
The system uses composite construction combining different materials for different components: polyurethane for the seating surfaces (providing durability and water resistance), steel for the structural frame and legs (providing strength and stability), and appropriate connection mechanisms. This composite approach achieves the required strength while managing complexity through material-appropriate component design.

AI summary
A device (100) includes a substantially planar portion (101) defining a seat (106). One or more legs (110,111,112,113) are coupled to, and support, the seat. The seat includes a first seat edge (104) defining a bench receiver (122) that is selectively attachable to a seat receiver (422) of a bench (400) to extend the substantially planar portion along a plane (107) defined by the substantially planar portion by a predefined additional width (601).
