Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional walking assist devices require the user to lift them off the ground for movement, lacking the ability to automatically follow the user's movements and provide stable support.

Innovation Solution

A power-assisted walking device with an electromotive system that responds to user movements, using a tactile joystick mechanism to control direction and speed, maintaining contact with the ground and providing self-leveling capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a conventional walking assist device uses a flat bottom for stable support, then stability is improved, but the device cannot automatically follow user movements and requires manual lifting for repositioning

Engineering Contradiction:

ImprovestabilityVSAvoidease of operation

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent replaces the purely mechanical flat-bottom support system with an electromotive device that uses electrical motors and control systems to achieve automatic following of user movements, eliminating the need for manual lifting while maintaining stability through active control mechanisms

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The electromotive device enables the walking assist device to automatically follow and adapt to user movements without requiring manual intervention for repositioning, allowing the device to serve itself by detecting and responding to user intent through sensors and control algorithms

Inventive Principle:

Principle #25Self-service

2Device complexity

If a walking assist device is designed to be manually operated, then device complexity is reduced, but automation and responsiveness to user movements are limited

Engineering Contradiction:

Improvedevice complexityVSAvoidautomation

Core Design Contradiction:

Device complexityVSExtent of automation

Solution Approach 1:

The patent segments the walking assist device into distinct functional modules including the electromotive device, sensor systems, control unit, and support structure, allowing each component to be optimized independently while working together to achieve automatic following functionality

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The electromotive device serves multiple functions including propulsion, steering, and automatic following of user movements, consolidating what would traditionally require separate mechanical systems into a single integrated platform that enhances automation without proportionally increasing complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)
