Solution Overview

Problem

Existing seating systems, including wheelchairs, often lack the ability to readily alter the extent and location of contoured cushioning to accommodate individual user needs, leading to discomfort and safety issues for high-needs users, and are typically not adaptable for different users over time.

Innovation Solution

A backrest contouring device featuring a substrate with adjustable pockets that can hold inserts of varying sizes and shapes, allowing for customizable contouring by placing inserts in specific pockets to modify the posture and position of a user, with elasticated fabric for flexibility and a cushioning layer for added comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed contouring is provided in seating systems, then structural simplicity is maintained, but adaptability to individual user needs deteriorates

Engineering Contradiction:
Improveadaptability to user needsVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The backrest is divided into multiple adjustable sections or zones, each capable of independent contouring adjustment. This segmentation allows different regions to be customized for different user needs while maintaining overall structural organization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The contouring elements are designed to be dynamically adjustable rather than fixed, allowing users to modify the shape and position of cushioning areas according to their changing needs over time.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If customised contouring is provided for high needs users, then comfort and safety are improved, but ease of operation deteriorates due to difficulty in adjustment

Engineering Contradiction:
Improveease of adjustmentVSAvoidposture support reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system enables users to independently adjust and customize their own seating contours without requiring caregiver intervention, promoting autonomy while ensuring proper posture support.

Inventive Principle:
Principle #25Self-service

3Productivity

If fixed contouring devices are used, then manufacturing simplicity is maintained, but loss of time deteriorates due to inability to reuse seats for different users

Engineering Contradiction:
Improveseat reuse efficiencyVSAvoidmanufacturing complexity
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The seating system is designed with universal adjustability features that allow a single seat to serve multiple users with different contouring requirements, increasing asset utilization and reducing the need for multiple specialized seats.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The invention relates to a contouring device for a seat base, backrest, or mattress. The device comprises a substrate having a first surface and an opposing second surface, the first and second surfaces each comprising a plurality of pockets adapted to receive one or more inserts therein. Inserts of various sizes and shapes can be placed within selected pockets of the device to provide a contoured surface that suits the needs of the user of the device. For example, the device can be adapted to provide contours that encourage a user to adopt a preferred posture when seated or lying down.
