Magnetic Joint Support Positioning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing joint support adjustable devices struggle to maintain stable positioning, especially for elderly or children, due to difficulty in precise operation and accidental disengagement of positioning pins under impact.
Innovation Solution
A joint support adjustable device featuring a base with arcuately arranged toothed recesses and a magnetic positioning mechanism, allowing for easy angle adjustment and stable positioning through magnetic attraction, preventing disengagement from impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a positioning pin is inserted into a positioning hole to adjust and position the joint support adjustable device, then the device can be positioned, but it cannot be positioned firmly when used on elderly or children who are incapable of moving deftly and operating the device precisely
Solution Approach 1:
The patent replaces the traditional mechanical positioning pin system with a magnetic positioning system. The positioning assembly includes a magnetic component that interacts with a corresponding magnetic component in the base, enabling automatic positioning and firm engagement through magnetic attraction without requiring precise manual insertion by the user.
Solution Approach 2:
The magnetic positioning system enables self-positioning functionality where the positioning assembly automatically aligns and engages with the base through magnetic attraction. This eliminates the need for users to manually insert positioning pins into precise holes, allowing the device to self-correct and maintain proper positioning even with imprecise user input.
2Ease of operation
If a pressing button radially protrudes out of the plate body to allow angle adjustment, then the device can be adjusted, but the positioning pin may be disengaged from the toothed recess under accidental impact
Solution Approach 1:
The patent replaces the mechanical pressing button system with a magnetic positioning system. The magnetic attraction between the positioning assembly and base provides continuous holding force that maintains engagement under impact conditions, eliminating the vulnerability of mechanical buttons that can accidentally disengage the positioning pin from the toothed recess.
Solution Approach 2:
The magnetic positioning system provides preliminary anti-action by creating a magnetic field that continuously counteracts external impact forces before they can cause disengagement. The magnetic attraction force acts in advance to prevent the positioning assembly from being knocked out of engagement, rather than relying on mechanical interlocking that can fail under impact.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances user safety and reliability by ensuring the positioning assembly remains engaged, facilitating easy operation and precise adjustments even under unexpected impacts.
Implementation Method 1
at least one of the positioning assembly and the fixation member is magnetic to attract the other so that the positioning assembly has a tendency to move toward the center
