Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing balancing devices, such as seat pads and sitting balls, are unstable and pose a risk of rolling away, making them unsuitable for balancing exercises, and therapy tops with smooth surfaces lack dynamic movement, limiting their effectiveness for training balance and proprioception.
Innovation Solution
A fluid-filled balancing device with a one-piece hollow body, featuring a concavely curved floor surface, an outwardly directed flange for enhanced stability, and adjustable fastening options, allowing for dynamic balancing and integration with therapy gyroscope functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a smooth rounded surface is used for therapy tops, then balance exercises can be performed, but dynamic movement is limited and effectiveness for training balance and proprioception is reduced
Solution Approach 1:
The patent applies the dynamics principle by using a fluid-filled hollow body that can dynamically adapt its shape and resistance in response to user movement. The fluid inside the hollow body creates dynamic resistance that changes with the speed and direction of movement, providing both stability for balance exercises and dynamic challenge for proprioception training.
Solution Approach 2:
The patent implements parameter changes by allowing the physical parameters of the balancing device to change in response to user interaction. The fluid-filled chamber changes its internal pressure distribution and shape characteristics based on the force and speed of user movement, thereby adapting the device's mechanical properties during use.
2Ease of operation
If sitting balls are used, then seating is possible, but the unstable shape causes rolling away and creates accident risks
Solution Approach 1:
The patent uses a controlled curvature approach with a flanged base design. The hollow body has a rounded upper surface for comfort but transitions to a flanged base structure that prevents rolling. This combines the beneficial curved surface for seating with a stable base geometry that eliminates the rolling hazard of pure spherical designs.
Solution Approach 2:
The patent segments the balancing device into distinct functional zones: an upper hollow body portion for seating and balancing, and a lower flanged base portion for stability. This segmentation allows each part to optimize its function - the rounded upper part provides comfort while the flanged base provides anti-roll stability.
3Strength
If seat pads with enclosed fluid volume are used, then elastic rigidity is achieved, but positioning stability on the floor is insufficient
Solution Approach 1:
The patent extends the device into a new dimensional space by adding a flanged base that protrudes below the main body. This flange creates a broader footprint on the floor surface, providing geometric stability that complements the elastic rigidity provided by the enclosed fluid volume in the vertical dimension.

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 device provides ergonomic and dynamic balancing, reducing the risk of injury and promoting neuromuscular function, proprioception, and deep muscle engagement, suitable for therapeutic and sports applications.
Implementation Method 1
A fluid-filled balancing device with a one-piece hollow body... The hollow body defines at least one fluid-fillable chamber that is filled with fluid
Implementation Method 2
Such seat cushions are either filled with elastic or resilient materials, for example feathers, foam or the like
Implementation Method 3
A plastic ring made of soft plastic is molded onto the underside of the floor element in the edge area, which ensures soft, elastic and at the same time non-slip floor contact
