Solution Overview

Problem

Existing methods for managing challenging behaviors in individuals with intellectual and developmental disabilities, such as physical and chemical restraints, are traumatic, costly, and pose health risks, while alternative solutions are lacking.

Innovation Solution

A fabric material composed of nylon, cotton, and modacrylic fibers, woven in a herringbone pattern, providing inherent flame retardancy and strength, used in an intervention apparatus with a rolling mechanism to deflect and absorb aggressive behavior without restraint.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical restraint is used to manage challenging behaviour, then safety of carers and individuals is improved, but trauma and reinforcement of behavioural issues increase

Engineering Contradiction:

ImprovesafetyVSAvoidtrauma

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The bean bag intervention apparatus serves as an intermediary tool between the carer and the individual displaying challenging behaviour. It provides physical protection and safety without requiring direct physical restraint of the individual, thereby preventing trauma while maintaining safety for both parties.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical system of physical restraint with a different mechanical approach using a soft, absorbent bean bag apparatus that dissipates force through deformation rather than constraining the individual's body.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Speed

If chemical restraint is used to manage challenging behaviour, then immediate control is improved, but health risks and side effects increase

Engineering Contradiction:

Improvecontrol speedVSAvoidhealth risks

Core Design Contradiction:

SpeedVSObject-affected harmful factors

Solution Approach 1:

The patent substitutes chemical intervention with a mechanical/physical intervention using a bean bag apparatus that provides control through physical absorption and dissipation of force, eliminating health risks associated with chemical substances while maintaining control capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If mechanical restraint devices are used to manage challenging behaviour, then control effectiveness is improved, but injury risk and dehumanisation increase

Engineering Contradiction:

Improvecontrol effectivenessVSAvoidinjury risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The bean bag intervention apparatus uses flexible, soft material that can deform and absorb force, providing control effectiveness without the rigid, potentially injurious structures of traditional mechanical restraint devices. The flexible nature prevents injury while maintaining control capability.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The bean bag apparatus inherently provides cushioning protection before contact occurs, with its soft, deformable structure designed to absorb and dissipate force during interaction, preventing injury before it can occur rather than mitigating injury after contact.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

4Reliability

If fire retardant chemical treatments are applied to fabric, then flame safety is improved, but toxicity risks increase

Engineering Contradiction:

Improveflame safetyVSAvoidtoxicity

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent converts the potential harm of chemical treatments into a benefit by using inherently flame-retardant natural fibers (modacrylic and cotton) that do not require toxic chemical coatings, thereby achieving flame safety while eliminating toxicity risks associated with chemical treatments.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The fabric uses a composite blend of naturally flame-retardant fibers (modacrylic and cotton) combined with nylon for strength, achieving fire safety through the inherent properties of the composite material rather than through toxic chemical treatments.

Inventive Principle:

Principle #40Composite materials

5Reliability

If restrictive practices are used to manage challenging behaviour, then immediate safety is improved, but quality of life and staff turnover increase

Engineering Contradiction:

ImprovesafetyVSAvoidquality of life

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The bean bag apparatus serves as a mediator that provides safety without the negative impacts of restrictive practices on quality of life. It enables carers to manage challenging behaviour effectively while maintaining a more humane and adaptable approach that does not compromise the individual's well-being or staff retention.

Inventive Principle:

Principle #24Intermediary (Mediator)
