Solution Overview

Problem

Existing upper body workout devices require the use of hands, limiting exercises that can be performed without hand involvement, particularly for individuals who need to focus on hand-free workouts or have hand injuries.

Innovation Solution

A forearm sleeve with a securing unit and attachment members that allows for hand-free engagement with weight lifting apparatuses by securing the forearm and attaching to cabling at various angles, enabling different upper body workouts without using hands.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing upper body workout devices are used, then hand involvement is required for operation, but this limits exercises for individuals with hand injuries or those needing hand-free workouts

Engineering Contradiction:

Improveadaptability to hand-free operationVSAvoidoperation without hand involvement

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces a forearm-mounted interface device as an intermediary between the user's body and the weight lifting apparatus. This device includes a securing unit that attaches to the forearm and attachment members that engage with the cabling, allowing the forearm to control the exercise equipment without requiring hand involvement. The intermediary device transfers the control function from the hand to the forearm.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the forearm is used to control weight lifting apparatus instead of hands, then hand-free workouts are enabled, but the forearm must be securely stabilized to prevent sliding

Engineering Contradiction:

Improvehand-free workout capabilityVSAvoidstability of forearm positioning

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The securing unit is designed to be applied to the forearm before the workout begins, establishing a secure attachment that prevents sliding during exercise. The securing unit includes straps or fastening mechanisms that are tightened and positioned in advance to ensure the forearm interface remains stable throughout the workout session.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The securing unit is designed to conform to the curved surface of the forearm, utilizing the natural cylindrical shape of the limb. This curved design allows the securing unit to wrap around and grip the forearm effectively, distributing pressure evenly and preventing sliding during movement.

Inventive Principle:

Principle #14Spheroidality (Curvature)

3Adaptability or versatility

If attachment members are positioned on the securing unit, then engagement with cabling at various angles is enabled, but the device structure becomes more complex

Engineering Contradiction:

Improvevaried exercise anglesVSAvoidstructure of sleeve assembly

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The attachment members are designed to provide multiple functions: they secure the cabling to the forearm interface, allow adjustment of cable angles for different exercises, and maintain tension during movement. This multi-functionality reduces the need for separate components for each function, thereby limiting the increase in overall device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A cable attachable forearm cover assembly for performing upper body workouts without using a person's hands includes a sleeve that is worn on a forearm of a person. A securing unit is positioned on the sleeve and secures a hand of the person to the sleeve to inhibit the sleeve from sliding along the forearm. A plurality of attachment members is positioned on the securing unit and engages cabling of a weight lifting apparatus.
