Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional walking aids and wheelchairs are cumbersome for users who are unable to walk, as they require manual or assisted movement when the device is out of reach, posing a significant burden for users in rehabilitation or medical care settings.
Innovation Solution
A multifunctional walking aid device equipped with a moving body, message receiving element, positioning element, and processor that allows automatic navigation to the user's location, utilizing image sensors, pressure sensing elements, and drive assemblies to adjust position and orientation, enabling autonomous movement and mode switching based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional wheelchairs or walking aids are used, then users can receive support during walking or riding, but users must manually or ask others to move the device when it is too far away, which is troublesome and burdensome
Solution Approach 1:
The walking aid device is equipped with automatic navigation capabilities including message receiving elements, positioning elements, and processors that enable the device to autonomously locate and move toward the user without manual intervention. The device can automatically follow the user's location and navigate to them, making the system serve itself rather than requiring user effort to move the device.
Solution Approach 2:
The patent replaces manual mechanical pushing or pulling of the device with an automated navigation system. The mechanical system of manual operation is substituted with electronic components including message receiving elements, positioning elements, processors, and automatic driving mechanisms that autonomously control the device's movement toward the user.
2Adaptability or versatility
If automatic navigation and mode switching features are added to the walking aid device, then user mobility and independence are enhanced, but the device complexity increases
Solution Approach 1:
The walking aid device is designed to perform multiple functions including automatic navigation to user location, following user movement, mode switching between walking assistance and riding modes, and autonomous operation. This multi-functional design allows a single device to serve various mobility needs without requiring separate specialized equipment.
Solution Approach 2:
The device incorporates dynamic mode switching capabilities that allow it to adapt between different operational states. The processor can switch between navigation mode, following mode, walking assistance mode, and riding mode based on user needs and environmental conditions, making the system flexible and adaptable rather than static.

AI summary
A walking aid device including a moving body, a message receiving element, a positioning element, and a processor is provided. The message receiving element, the positioning element, and the processor are respectively disposed at the moving body, and the message receiving element and the positioning element are respectively electrically coupled to the processor. The message receiving element is configured to receive a message from a target, and the positioning element is configured to locate a position of the moving body. When the message from a target is received by the message receiving element, the processor determines an orientation of the target according to the message, and the positioning element locates the position of the moving body. The processor produces a position data according to the orientation of the target and the position of the moving body, and controls the moving body to move to where the target is located.
