Fitness Stool with Sliding System and Limiting Mechanism for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fitness equipment with sliding systems and elastic devices for damping and reset lacks stability, leading to excessive movement and management difficulties when used as indoor or outdoor fitness stools.
Innovation Solution
A fitness stool design incorporating a sliding system with a support and connection frame that moves upwards and downwards, combined with an elastic device for damping and return, along with rotatable wing plates and a pulley or linkage mechanism, to provide stability and prevent shifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the support and connection frame is allowed to move freely with sliding system and elastic device, then the fitness equipment provides exercise functionality, but the equipment becomes unstable and shifts around
Solution Approach 1:
The patent applies dynamics by allowing the support and connection frame to move vertically through the sliding system and elastic device for exercise functionality, while simultaneously using the limiting mechanism to constrain horizontal movement, creating a dynamically controlled motion system that provides both freedom and stability
2Ease of operation
If the sliding system allows upward and downward movement, then exercise motion is enabled, but the equipment can be easily moved and lost
Solution Approach 1:
The patent implements dynamics by enabling vertical movement through the sliding rod and elastic device for exercise purposes, while the limiting mechanism prevents excessive displacement and horizontal shifting, ensuring the equipment remains secured during operation
Solution Approach 2:
The patent applies parameter changes by modifying the degrees of freedom of the support frame - allowing movement in the vertical direction (y-axis) while constraining horizontal movement (x-axis and z-axis), thus changing the motion parameters to achieve both exercise functionality and equipment security
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
The design results in a firm and stable fitness stool that prevents movement and loss, facilitating easy management by restricting excessive movement while allowing for effective exercise through controlled upward and downward motion.
Implementation Method 1
The elastic device for elastic damping and elastic return is provided between the ground and the support and connection frame
Implementation Method 2
The elastic device for elastic damping and elastic return is provided between the ground and the support and connection frame

AI summary
A fitness stool includes a sliding system, a support and connection frame and an elastic device. One end of the sliding system is inserted into and fixed to the ground of the earth and the other end of the sliding system is connected with the support and connection frame. The support and connection frame can be moved upwards and downwards relative to the ground, and the sliding system comprises a sliding rod and a sliding cavity. The elastic device realizes elastic damping and elastic return between the ground and the support and connection frame.
