Solution Overview

Problem

Existing hand exercisers are unable to effectively cross-train between all muscle groups of the hand, including finger-strength, grip-strength, wrist-strength, extension-strength, and finger-hand dexterity, requiring users to utilize multiple devices and often leading to imbalanced muscle development.

Innovation Solution

A hand exerciser with an arc-shaped flexible frame, detachable resistance member, half-rounded vertical rails, and an adjustable support strap, which provides resistance and texture for fingers and thumb, allowing for balanced development of hand muscles and dexterity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a hand exerciser is designed to focus on a specific muscle group, then it can effectively develop that muscle group, but it cannot develop other muscle groups, requiring multiple devices

Engineering Contradiction:
Improveability to cross-train between muscle groupsVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hand exerciser is designed with a flexible frame and multiple platforms that can accommodate different finger and thumb configurations, allowing a single device to target multiple muscle groups including finger-strength, grip-strength, wrist-strength, extension-strength, and finger-hand dexterity through various exercise modes

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple hand exercisers are used to develop all muscle groups, then comprehensive hand development is achieved, but time and money are wasted

Engineering Contradiction:
Improvecomprehensive muscle group coverageVSAvoidtime to use multiple devices
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The device combines multiple exercise functions into a single hand exerciser, integrating capabilities that would traditionally require separate devices for finger strength, grip strength, wrist strength, extension strength, and dexterity training, thereby eliminating the need to switch between multiple devices and reducing total training time

Inventive Principle:
Principle #5Merging (Combining)

3Force

If resistance is provided for finger compression, then finger-strength is developed, but extension-strength muscles receive insufficient counter-balance exercise

Engineering Contradiction:
Improvecompression resistanceVSAvoidextension strength development
Core Design Contradiction:
ForceVSAdaptability or versatility

Solution Approach 1:

The device provides counter-balancing resistance for extension movements through its flexible frame structure that offers resistance in both compression and tension directions, allowing the extension-strength muscles to receive adequate exercise that balances the compression resistance provided for finger-strength development

Inventive Principle:
Principle #8Anti-weight (Counterweight)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables efficient and effective cross-training between all hand muscle groups, improving finger and thumb strength and dexterity, reducing the need for multiple devices and promoting overall hand health.

Implementation Method 1

a resistance member removably secured to the inner surface of the flexible frame between the first and second platforms when the flexible frame is in the arc-shaped configuration to provide resistance between the first and second platforms

Methodology Applied
Scientific EffectCompression: Compression

AI summary

A hand exerciser that is structured and arranged to strength the various muscle groups of the user's hand and to improve dexterity of the user's fingers and thumb. The hand exerciser comprises a flexible frame formed into an arc-shaped configuration having an outer surface and an inner surface. On the outer surface of the frame is a first platform at one end and a second platform at the opposite end. A resistance member, such as compressible foam, a bag or the like, is removably positioned against the inner surface inside the arc-shaped frame between the two platforms such that when the user presses the platforms between the fingers and thumb, the resistance member resists compression to exercise the hand. Rails and elongated members on the first platform assist with the improving strength and dexterity. Sensor pads, light and/or audio generators and a cell phone support apparatus can be utilized.
