Solution Overview

Problem

Stability balls are limited in providing stability and instability options, tend to roll out of position during exercises, lack a convenient area for grasping, and occupy excessive space due to their spherical shape, making them impractical for certain workouts and storage.

Innovation Solution

A stackable exercise device with a substantially spherical member featuring a flattened portion, internal cavity, and a lip for grasping, allowing for both stability and instability use while being securely stackable and space-efficient.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a spherical shape is used for the exercise ball, then it provides instability for core muscle training, but it rolls out of position during exercises

Engineering Contradiction:

Improveinstability for core muscle trainingVSAvoidposition stability during exercise

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The exercise ball incorporates a flattened portion at a specific location rather than making the entire surface flat. This localized modification provides a stable base area for the ball to rest on during exercises, preventing it from rolling away, while the rest of the spherical surface maintains its instability characteristics for effective core muscle training.

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If a spherical shape is used for the exercise ball, then it provides instability for exercise, but it occupies excessive storage space

Engineering Contradiction:

Improveinstability for exerciseVSAvoidstorage space requirement

Core Design Contradiction:

Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The exercise ball features a recessed cavity that can accommodate another exercise ball or storage items. This nesting capability allows multiple balls to be stored within each other or alongside equipment, significantly reducing the storage space required while maintaining the spherical shape for exercise functionality.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Adaptability or versatility

If a spherical shape is used for the exercise ball, then it provides instability for exercise, but it lacks a convenient area for grasping

Engineering Contradiction:

Improveinstability for exerciseVSAvoidgrasping convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The exercise ball includes a flattened portion with a specific contour that creates a grasping area. This localized feature provides a convenient surface for users to hold onto during exercises, improving ease of operation while the rest of the spherical surface maintains the instability needed for core muscle training.

Inventive Principle:

Principle #3Local quality
