Solution Overview

Problem

Current mobility aids for individuals with motor difficulties, such as stabilizers and wheelchairs, often lack ergonomic design, are cumbersome, and do not allow for easy transition from seated to standing positions, nor do they provide independent outdoor use or adequate support for upper limbs, leading to safety hazards and limited functionality.

Innovation Solution

A compact stabilizer device with a central vertical frame, adjustable saddle, and actuated seat, equipped with joystick control and safety features, allowing users to transition from seated to standing positions and move independently indoors and outdoors, while protecting electrical connections and providing lateral support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If stabilisers are designed to lift and hold users in a static upright position, then user support and stability are improved, but user mobility and independence are worsened

Engineering Contradiction:
Improveuser supportVSAvoiduser mobility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The stabiliser transitions from a static design to a dynamic one, enabling the seat to move between horizontal and vertical positions. The device allows users to transition from seated to standing position and move independently indoors using joystick control, transforming the device from a fixed support structure to an adaptable mobility aid that responds to user needs

Inventive Principle:
Principle #15Dynamics

2Reliability

If stabilisers use wide back supports and restraining straps, then user stability is improved, but user comfort and ease of adjustment are worsened

Engineering Contradiction:
Improveuser stabilityVSAvoidadjustability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The stabiliser enables users to independently adjust and operate the device without assistance from companions. Users can control the seat position transitions and movement independently through joystick control, eliminating the need for external assistance while maintaining stability and support

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If stabilisers use articulated and exposed crank mechanisms, then mechanical functionality is improved, but user safety is worsened

Engineering Contradiction:
Improvemechanical functionalityVSAvoidsafety hazards
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent removes the exposed crank mechanisms and articulated linkages from the user environment. The mechanical functionality is retained through motorized actuators that operate internally, eliminating the safety hazards of exposed moving parts while maintaining the ability to transition between seating positions

Inventive Principle:
Principle #2Taking out (Extraction)

4Adaptability or versatility

If wheelchairs and stabilisers are designed with large wheels, then outdoor usability is improved, but indoor manoeuvrability is worsened

Engineering Contradiction:
Improveoutdoor usabilityVSAvoidindoor manoeuvrability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The stabiliser is designed to function universally across different environments - both indoors and outdoors. The device combines features that enable narrow manoeuvring for indoor use while maintaining stability and support for outdoor applications, creating a multi-functional mobility solution that adapts to various usage contexts

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

AI summary

This invention consists of a mobile device that allows users with motor difficulties to easily, gradually and independently change their posture from sitting to standing, with the option of stopping in any intermediate condition, to maintain the acquired position with bi-podalic load as well as to move around indoors, independently and without any assistance, by using the joystick steering control, moving in an upright position, or in any that is deemed to be the most suitable for one's needs.
