Exercise Ball Textile Cover for Static, Slip, and Stability Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fitness balls used for training and as sitting members are prone to static polarization, breathability issues, and slipping, making them unsuitable for prolonged use at home or office without risking injury.
Innovation Solution
A cover for an exercise device made of high-resistant plastic with a textile cover that is breathable, antistatic, and slip-resistant, featuring an asymmetrical mass distribution for stability, and a zip fastener for easy inflation and cleaning, along with a handle for easy transport and positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fitness ball made of artificial elastic material (PVC) is used, then it maintains its shape through pressurized air and provides unstable support for muscle training, but it polarizes easily through friction, captures dust and dirt through electrostatic attraction, and is not breathable causing significant perspiration
Solution Approach 1:
The patent applies composite materials by combining an inner PVC shell (for shape maintenance and pressurization) with an outer textile cover (for breathability and anti-static properties). This composite structure resolves the contradiction by allowing each material to fulfill its specific function: the PVC provides structural integrity while the textile layer eliminates harmful static effects and improves breathability.
Solution Approach 2:
The patent applies local quality by giving different parts of the ball different properties: the inner shell is made of rigid PVC for shape maintenance, while the outer cover is made of breathable, anti-static textile material. This localized differentiation allows the ball to simultaneously achieve shape stability and eliminate harmful static effects only where needed (at the surface contact points).
2Adaptability or versatility
If a fitness ball is used as a sitting member, then it allows training muscles and maintaining correct posture, but the lower portion slides or rolls with respect to the floor making the user fall with possible risk of injury
Solution Approach 1:
The patent applies asymmetry by creating an asymmetric mass distribution within the ball, with a higher density zone positioned at the lower portion. This asymmetric weight distribution creates a stabilizing effect that prevents the ball from rolling or sliding uncontrollably, while still allowing it to be used as a sitting member for exercise and posture training.
3Stability of the object's composition
If the outer shell material is used, then it maintains shape through pressurized air, but it is not breathable and causes significant perspiration during prolonged use
Solution Approach 1:
The patent applies flexible shells and thin films by using a textile cover as the outer layer. This thin film structure is breathable and allows perspiration to escape, while still maintaining the overall shape of the ball through the underlying pressurized PVC shell. The textile cover acts as a flexible barrier that permits vapor transmission while preserving structural integrity.
