Solution Overview

Problem

Existing hand strength devices do not effectively enhance grip strength for video game controller users, particularly in mimicking the form and function of a video game controller.

Innovation Solution

A hand strength device designed to resemble a video game controller, featuring grips, connection points for elastic members, and adjustable resistance through multiple elastic bands, allowing users to perform exercises that mimic controller usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing hand strength devices are used, then hand exercise function is provided, but they do not effectively enhance grip strength for video game controller users

Engineering Contradiction:

Improveadaptability to video game controller usageVSAvoideffectiveness in enhancing grip strength

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The device copies the form factor and layout of a video game controller, creating a familiar interface that users can grasp and manipulate in the same way. This includes replicating the dual-hand grip configuration and button arrangement, making the exercise device directly adaptable to video game controller usage patterns

Inventive Principle:

Principle #26Copying

2Strength

If adjustable resistance is provided through multiple elastic bands, then grip strength training effectiveness is improved, but device complexity increases

Engineering Contradiction:

Improvegrip strength training effectivenessVSAvoidstructure complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The resistance system is segmented into multiple independent elastic bands, each attachable at different connection points on the device body. This allows the resistance mechanism to be divided into modular components that can be independently selected and combined, providing adjustable resistance without requiring a monolithic complex structure

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The elastic bands serve multiple functions: they provide resistance for grip strength training, allow for adjustable difficulty levels, and can be configured for different exercise types. This multi-functionality reduces the need for separate mechanisms for each training parameter

Inventive Principle:

Principle #6Universality (Multi-functionality)
