Modular Wheelchair Contouring System for Adaptable Seating Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing contouring systems for wheelchair seats are labor-intensive and expensive, requiring bespoke manufacturing, which is inflexible to changes in user needs over time, such as growth or posture changes.
Innovation Solution
A contouring system comprising a support element with attachable contouring units and stabilizers, allowing for customizable and adjustable contouring through a modular design with air vents for breathability, enabling easy reconfiguration to meet individual user needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If bespoke manufacturing is used to create customised wheelchair seats, then the seating can be tailored to individual user needs, but the process becomes labour intensive and expensive
Solution Approach 1:
The seat is divided into multiple modular elements including base layers, contouring layers with adjustable contours, and cover layers. Each layer can be independently selected and configured to meet specific user requirements, allowing customisation without bespoke manufacturing of the entire seat.
Solution Approach 2:
The modular elements are designed with standardised interfaces and configurations that can be combined in various ways to serve different user needs. The same set of modular components can be reconfigured to accommodate growth, posture changes, or different users, replacing the need for completely new bespoke seats.
2Adaptability or versatility
If bespoke manufacturing is used for wheelchair seats, then individual user requirements are met, but the user must wait while the seat is being manufactured
Solution Approach 1:
The modular seat elements are pre-manufactured and stored in ready-to-assemble configurations. When a user needs a customised seat, the pre-prepared modules can be quickly selected and assembled, eliminating the lengthy manufacturing wait time associated with bespoke seats while still meeting individual user requirements.
3Reliability
If traditional contouring systems are used, then seating support is provided, but the system lacks flexibility to adapt to changes in user needs over time
Solution Approach 1:
The contouring layers incorporate adjustable and reconfigurable elements that can be modified as user needs change. The modular design allows contours to be repositioned, added, or removed without replacing the entire seat, providing both reliable support and adaptability to growth or posture changes over time.
4Ease of operation
If customised wheelchair seats are manufactured, then user comfort is improved, but the process is labour intensive
Solution Approach 1:
By segmenting the seat into pre-manufactured modular elements, the labour intensity is shifted from custom assembly to standardized production of individual components. This allows comfortable, customised seats to be assembled from pre-prepared modules rather than manufactured entirely to order.
