Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tilting inversion exercisers require significant user effort to rotate and maintain the supporting table at desired angular positions, and motorized mechanisms are expensive and complex, increasing manufacturing costs.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a motorized mechanism is used to tilt the user supporting table, then ease of operation is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The actuator is designed to automatically lock the carrier at selected angular positions without requiring user intervention. The release valve mechanism enables the actuator to hold position passively, making the system self-servicing and eliminating the need for complex motorized controls while maintaining ease of operation.
Solution Approach 2:
The patent extracts the motorized mechanism from the system and replaces it with a simplified actuator using a release valve and piston rod. This removes the complex control systems, motors, and power requirements while retaining the essential tilting function, thereby reducing device complexity without compromising ease of operation.
2Ease of operation
If a motorized mechanism is used to tilt the user supporting table, then ease of operation is improved, but manufacturing cost increases
Solution Approach 1:
The actuator uses inexpensive components such as a release valve, piston rod, and linking arm instead of costly motorized systems. These simpler mechanical parts are easier and cheaper to manufacture, assemble, and maintain, significantly reducing production costs while still providing easy operation through the automated locking mechanism.
Solution Approach 2:
By removing the motorized mechanism and replacing it with a simple actuator system, the patent eliminates expensive components like motors, controllers, and power systems. This extraction of complex elements directly reduces manufacturing cost while maintaining ease of operation through the release valve-based automatic locking feature.
3Device complexity
If the user manually rotates and holds the supporting table, then device complexity is reduced, but force and energy requirements increase
Solution Approach 1:
The actuator with release valve automatically locks the carrier at the desired angular position, eliminating the need for the user to continuously apply force to hold the table. The system serves itself by maintaining position passively, reducing the force requirement to merely triggering the release valve rather than continuously supporting the table weight.
Solution Approach 2:
The actuator acts as an intermediary mechanism between the user and the heavy supporting table. Instead of the user directly handling the large forces required to rotate and hold the table, the actuator mediates this interaction by providing mechanical advantage and automatic locking, thereby reducing the force the user must exert while adding only minimal device complexity.

AI summary
A tilting inversion exerciser includes a supporting stand having a primary frame and an auxiliary frame, the primary frame includes two posts, two barrels on the posts, two shafts attached to the barrels, a carrier attached to the shafts for supporting a supporting table, and an actuator is coupled between one of the shafts and one of the posts and includes a release valve for releasing the actuator when the release valve is depressed and actuated, and for locking the actuator when the release valve is released. The user may easily actuate the release valve to release and to lock the actuator without applying much force or energy to rotate the carrier and the supporting table relative to the supporting stand.
