Sliding Stop Switch for Adjustable Wearable Chair Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable robots are heavy, require complex control, and have limited stability and adjustable sitting angles, making it difficult to support heavy loads while being lightweight and allowing for variable sitting positions.
Innovation Solution
A sliding stop switch mechanism with a switch member that slides and fixes along a rod to stop the rotation of another rod, allowing for adjustable sitting angles and secure support, using coupling protrusions and recesses with magnetic attraction for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional wearable chair structure is used, then the chair can support heavy loads, but the sitting angle cannot be changed and the structure becomes complex
Solution Approach 1:
The switch member is designed to be movable along the first rod, allowing the system to transition between different fixed positions. This dynamic element enables angle adjustment without requiring a completely reconfigurable structure, resolving the contradiction between adaptability and complexity by providing controlled variability through a simple sliding mechanism with magnetic stopping points
Solution Approach 2:
The adjustment mechanism is segmented into discrete fixed positions along the first rod, where the switch member can be positioned and fixed at multiple locations. This segmentation allows for multiple sitting angles while maintaining structural simplicity, as the mechanism doesn't require continuous adjustment capability but rather discrete positional options
2Adaptability or versatility
If a switch member is added to enable angle adjustment, then adaptability improves, but the device complexity increases
Solution Approach 1:
The magnetic attraction mechanism replaces complex mechanical locking systems with a simpler magnetic field-based stopping mechanism. The magnets on the first rod and switch member create automatic stopping points without requiring additional mechanical latches, springs, or cam mechanisms, thus improving adaptability while minimizing the increase in complexity
Solution Approach 2:
The switch member utilizes its own weight and the magnetic attraction force to automatically position and fix itself at the desired locations along the first rod. The user simply needs to slide the switch member to the appropriate position, and the magnetic force automatically holds it there, eliminating the need for additional actuating mechanisms or complex locking systems
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables a lightweight wearable chair with adjustable sitting angles and secure support, enhancing stability and usability by allowing easy movement and fixation of the switch member along the rod.
Implementation Method 1
At each position of the switch member at which the coupling protrusion on the switch member is inserted into one of the coupling recesses in the first rod, the switch member and the first rod may be provided with magnets, which face each other to attract each other.

AI summary
A sliding stop switch may include a first rod extending in the longitudinal direction thereof, a second rod coupled to the first rod such that one end portion thereof is slidable in the longitudinal direction of the first rod, and a switch member coupled to the first rod to slide in the longitudinal direction of the first rod and to be fixed at a plurality of points on the first rod to stop the sliding of one end portion of the second rod.
