Static-Dynamic Stabiliser Joystick Control
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
2Reliability
If stabilisers use wide back supports and restraining straps, then user stability is improved, but user comfort and ease of adjustment are worsened
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
3Adaptability or versatility
If stabilisers use articulated and exposed crank mechanisms, then mechanical functionality is improved, but user safety is worsened
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
4Adaptability or versatility
If wheelchairs and stabilisers are designed with large wheels, then outdoor usability is improved, but indoor manoeuvrability is worsened
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

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.
