Solution Overview

Problem

Conventional inversion tables are inaccessible and unsafe for individuals with disabilities, as they require upper extremity strength to invert and maintain positions, lacking immobilization and stability features.

Innovation Solution

A disability standing device with a mounting bracket, backrest, ankle clamp, wheels with locks, support rod, grip handles, and a locking device, allowing assistants to safely invert and lock users in standing or lying positions, enabling mobility and secure positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional inversion table is used, then inversion function is provided, but it is inaccessible and unsafe for individuals with disabilities who lack upper extremity strength

Engineering Contradiction:

Improveaccessibility to individuals with disabilitiesVSAvoidrequirement for upper extremity strength

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces an assistant-operated hand grip mechanism as an intermediary between the user and the inversion table. The assistant uses the hand grip to control the backrest rotation, eliminating the need for the disabled user to exert upper extremity force. This mediator transfers the operational burden from the user to the assistant, enabling accessibility for individuals with limited physical strength

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The locking device automatically secures the backrest at inverted and upright positions without requiring manual intervention from the user. The system self-locks at predetermined angles, eliminating the need for continuous manual effort to maintain positions, thereby enabling individuals with disabilities to benefit from inversion therapy safely

Inventive Principle:

Principle #25Self-service

2Reliability

If a conventional inversion table is used, then inversion function is provided, but there is no way to lock the backrest in position

Engineering Contradiction:

Improveposition stabilityVSAvoidlocking mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The locking device automatically engages at predetermined positions (inverted and upright) without requiring manual operation. The system self-secures the backrest at these positions, providing reliable position stability while minimizing the complexity of user interaction. The automatic locking mechanism ensures consistent positioning every time the backrest reaches the predetermined angles

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The locking device is pre-positioned to engage automatically when the backrest reaches predetermined angles. The locking mechanism is prepared in advance at specific positions, so that when the backrest rotates to these angles during inversion or return to upright, the locking action occurs automatically without requiring real-time manual intervention

Inventive Principle:

Principle #10Preliminary action

3Reliability

If a conventional inversion table is used, then inversion function is provided, but there is no way to immobilize or harness the user's body for safety

Engineering Contradiction:

Improvesafety and stabilityVSAvoidimmobilization system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The immobilization system is divided into separate functional components: stability straps for securing the user to the backrest, ankle clamps for securing the lower extremities, and arm rests for supporting the upper body. Each component addresses a specific body region independently, providing comprehensive immobilization while keeping the overall system manageable and not overly complex

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The stability straps serve multiple functions: they secure the user to the backrest, prevent sliding during inversion, and can be adjusted to accommodate different body sizes. The ankle clamps provide both immobilization and positioning functions. This multi-functionality increases safety without proportionally increasing device complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of operation

If a conventional inversion table is used, then inversion function is provided, but it is difficult to maintain upright position for those with disabilities

Engineering Contradiction:

Improveability to maintain upright postureVSAvoidarm and leg strength requirement

Core Design Contradiction:

Ease of operationVSForce

Solution Approach 1:

The locking device automatically secures the backrest in the upright position without requiring the user to exert force to maintain it. When the assistant rotates the backrest to the upright position using the hand grip, the locking mechanism automatically engages, holding the position stable. This eliminates the need for the disabled user to continuously engage arm and leg muscles to maintain upright posture

Inventive Principle:

Principle #25Self-service

AI summary

A disability standing device has a mounting bracket with strap holes, arm rests, an ankle clamp assembly, wheels with locks, a support rod, grip handles, a grip bar and a locking device. The mounting bracket has a rear supporting frame, a front supporting frame, arms rests for the user, grip handles for the assistant to push or pull the device for mobility, a grip bar for the assistant to pull the backrest in an up or downward motion and a locking device to lock the backrest into the desired position. Wherein the rear support frame houses the support rod to limit a patient's motion beyond being parallel with the floor so that their feet are limited to raising above parallel with the floor.
