Solution Overview
Problem
Conventional tilting inversion exercisers require significant user effort to maintain the supporting table at desired angles and lack adjustable structures that can accommodate varying user sizes and weights, leading to discomfort and increased manufacturing complexity and costs.
Innovation Solution
A tilting inversion exerciser with a supporting stand featuring a primary and auxiliary frame forming an inverted V structure, pivotally coupled carriers with guiding devices and spring biasing members to adjust the supporting table's position automatically, ensuring secure and comfortable use for users of different weights by adjusting the center of gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a typical inversion suspension exerciser with a pivotally attached supporting table is used, then the structure is simple and easy to manufacture, but the user has to spend a lot of force and energy to rotate and hold the table at selected angular positions
Solution Approach 1:
A spring biasing member is engaged between the carrier and supporting table to automatically adjust the center of gravity of the carrier relative to the supporting table. This counterbalances the weight of the user and the table, allowing effortless rotation and positioning without requiring the user to manually hold the table against gravity.
Solution Approach 2:
The spring biasing member automatically adjusts the center of gravity based on user weight, eliminating the need for manual adjustment mechanisms. The system self-regulates to accommodate different user sizes and weights without requiring complex adjustable structures or user intervention.
2Adaptability or versatility
If an adjustable structure is added to accommodate different user sizes and weights, then the exerciser can suitably support users of different dimensions, but the structure becomes complicated and manufacturing cost increases
Solution Approach 1:
The spring biasing member acts as a passive adaptive mechanism that automatically adjusts to different user weights. Instead of requiring active sensors, motors, or complex mechanical adjustment systems, the spring's elastic properties naturally accommodate varying loads, maintaining simplicity while achieving versatility.
Solution Approach 2:
The spring biasing member changes its compression state and the center of gravity position based on the user's weight. This passive parameter adjustment allows the system to adapt to different users without requiring structural modifications or complex control systems.
3Ease of operation
If a spring biasing member is engaged to automatically adjust the center of gravity, then the supporting table can be effortlessly adjusted to suitable positions, but the device structure becomes more complex
Solution Approach 1:
The spring biasing member provides automatic counterbalancing by adjusting the center of gravity of the carrier relative to the supporting table. This single passive component eliminates the need for motors, sensors, or complex control systems, achieving effortless operation with minimal added complexity.
