Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Individuals with disabilities, injuries, or limited mobility face challenges in maintaining proper leg alignment and mobility due to the lack of ergonomic, supportive tools, leading to discomfort, muscle atrophy, ligament deterioration, and hip misalignment, with existing devices failing to provide adequate comfort, stability, or adjustability, and posing risks of injury for both patients and caregivers.

Innovation Solution

A limb wrap device made of durable, soft, and tear-resistant material with a closure mechanism and repositionable handles, designed to securely fasten around the leg or arm, allowing easy adjustment and synchronization of movement, and equipped with handles for caregivers to assist in lifting and positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing slings or supports are used, then basic support is provided, but they fail to provide adequate comfort, stability, or adjustability

Engineering Contradiction:

ImproveadjustabilityVSAvoidstability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The device incorporates adjustable straps with buckles that allow dynamic adjustment of the wrap's fit and positioning. The straps can be lengthened or shortened to accommodate different body sizes and positions, providing both adaptability and stable support simultaneously.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The device allows changing of physical parameters such as wrap tightness, position, and configuration through adjustable straps and multiple fastening points. This enables the same device to adapt to different users and situations while maintaining reliable support.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If caregivers manually assist with leg movement, then positioning is achieved, but physical strain and injury risk increase

Engineering Contradiction:

Improveease of positioningVSAvoidphysical strain

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The device acts as an intermediary tool between the caregiver and the patient's limb. The integrated handles provide mechanical leverage and control, allowing caregivers to position limbs with minimal physical effort while reducing direct contact and strain on their bodies.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The device enables patients to perform some self-positioning through the handles and adjustable mechanisms, reducing the frequency and intensity of caregiver intervention. The self-adjusting features allow patients to make minor positioning adjustments independently.

Inventive Principle:

Principle #25Self-service

3Reliability

If non-ergonomic devices are used, then basic support is provided, but discomfort and skin irritation occur

Engineering Contradiction:

ImprovesupportVSAvoidskin irritation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The device uses a soft, flexible wrap material that conforms to the body's contours rather than rigid structures. This flexible shell design provides stable support while distributing pressure evenly and minimizing friction-induced skin irritation.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The device incorporates different material properties in different areas - softer materials in contact with skin, structured support elements where needed, and smooth surfaces to prevent irritation. This localized optimization provides support where required while minimizing harmful effects in contact areas.

Inventive Principle:

Principle #3Local quality

AI summary

A multifunctional body part wrap device designed to assist individuals with mobility, therapeutic needs, or patient transfers is disclosed. The device includes a wrap body made of durable, tear-resistant material, configurable in various sizes and shapes to accommodate different parts or limbs of the body. A closure mechanism such as hook-and-loop fasteners is used for secure wrapping of the device around a body part (i.e., limb) and at least one handle is attached to the body via sewn seams for providing movement and positioning by the user or a caregiver. One embodiment includes a plurality of apertures and a plurality of adjustable straps to synchronize movement of multiple limb (i.e., arm or leg) wraps for bilateral use. The device can also function as a padded sling support with sewn covers to prevent twisting and reduce friction for patient comfort during transfers.
