Solution Overview

Problem

Existing exercise devices lack upper body support during core muscle exercises, limiting the effectiveness and variety of movements that can be performed.

Innovation Solution

A hemispherical base with wheels and a locking mechanism, combined with an upper body platform and adjustable support, allows for dynamic core muscle exercises by maintaining balance and enabling controlled movements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the base is made stationary on a flat surface, then stability is improved, but core muscle engagement and balance training effectiveness deteriorate

Engineering Contradiction:

Improvebase stabilityVSAvoidcore muscle engagement

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The base features a hemispherical upper surface instead of a flat surface. This curved geometry creates an unstable platform that requires the user to actively engage core muscles to maintain balance, while the spherical shape provides multi-directional movement capability for comprehensive core training.

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The base is designed to be dynamically movable on the support surface through wheels, transitioning from a static stable platform to a dynamic unstable platform. This allows the base to move in response to user movements, providing active balance training while maintaining controllability.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the base is made movable on the support surface, then core muscle engagement is improved, but stability and control deteriorate

Engineering Contradiction:

Improvecore muscle engagementVSAvoidbase stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

Wheels are introduced as an intermediary mechanism between the base and the support surface. This allows the base to move smoothly and controllably in response to user movements while maintaining stability through the rolling contact, rather than sliding or tipping uncontrollably.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If upper body support is added to the exercise device, then exercise variety and effectiveness are improved, but device complexity increases

Engineering Contradiction:

Improveexercise varietyVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The upper body support structure is merged with the base assembly, integrating the support function into the existing movable platform. This combination allows the support structure to move with the base, providing stable upper body support during dynamic core exercises without requiring a separate fixed support system.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An exercise device for exercising generally with particular attention to the core muscles of the torso and abdomen includes a base. An upper surface of the base is hemispherical to require a person kneeling on the base to flex core muscles to maintain balance on the base. Each of a plurality of wheels is coupled to a bottom of the base. A stand includes a pedestal having a receiver complementary to the base. An upper body platform includes a pair of arm rests and a pair of grips. A support extends between the upper body platform and the pedestal. A locking mechanism secures the base to the pedestal such that the base is in a static position relative to the stand when the locking mechanism is engaged.
