Solution Overview

Problem

Existing muscle exercising devices that rely on handles or elastic cords limit the engagement of larger muscles due to reliance on hand and finger strength, and often result in injury from slipping handles or excessive recoil force.

Innovation Solution

A versatile, elastic exercise sleeve with multiple positioning sleeves that accommodate different body parts, providing variable resistance without the need for latches or buckles, allowing users to engage larger muscles through controlled flexion and extension without excessive recoil, using a combination of strong jersey knit and rib knit fabrics for comfort and control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If handles are used to extend the elastic device, then the device can be held and operated, but hand and finger strength becomes the limiting factor preventing engagement of larger muscles

Engineering Contradiction:

Improveability to hold and operate deviceVSAvoidengagement of larger muscles

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The invention removes handles entirely from the elastic exercise device, extracting the limiting component that required hand and finger strength. The elastic band is used directly on the body without intermediary handles, allowing larger muscles to engage without being constrained by grip strength limitations.

Inventive Principle:

Principle #2Taking out (Extraction)

2Force

If elastic cord with handles is used, then resistance exercise can be performed, but handles may slip out of hands with increased pressure resulting in injury

Engineering Contradiction:

Improveresistance forceVSAvoidhandle grip security

Core Design Contradiction:

ForceVSReliability

Solution Approach 1:

The invention eliminates handles that could slip from hands by using the elastic band directly on the body. This extraction of the problematic component removes the safety hazard entirely while maintaining the resistance exercise function through direct body application.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The body itself becomes the intermediary between the elastic band and the exercise motion. Instead of handles mediating the connection between hand and elastic cord, the body directly interfaces with the elastic band, creating a secure connection that cannot slip.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Force

If elastic cord is used for exercise, then resistance can be provided, but excessive recoil force limits the ability to hold maximum resistance

Engineering Contradiction:

Improveresistance forceVSAvoidability to hold maximum resistance

Core Design Contradiction:

ForceVSDuration of action of moving object

Solution Approach 1:

The invention modifies the elastic properties by using a fabric-based elastic band instead of a traditional elastic cord. This parameter change in material composition provides a more controlled recoil characteristic that allows users to hold maximum resistance for longer durations without being overwhelmed by excessive rebound force.

Inventive Principle:

Principle #35Parameter changes

4Adaptability or versatility

If multiple muscle groups are targeted, then comprehensive exercise is achieved, but device complexity increases with additional components

Engineering Contradiction:

Improvemultiple muscle engagementVSAvoidnumber of components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention creates a universal exercise device where a single elastic band can target multiple muscle groups through different application methods and exercise variations. By placing the band at different locations on the body (knees, elbows, wrists, ankles) and performing different movements, one simple component achieves comprehensive muscle engagement without requiring multiple specialized devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

There is provided by this invention a portable, elastic, and resilient exercising sleeve that can be placed around the torso and the extremities of the body for performing muscle strengthening and conditioning exercises that is generally comprised of a large elastic oblong center section having connected at opposite ends thereof a plurality of smaller elastic positioning sections with the large oblong center section and the smaller positioning sections co-joined to form a one piece multiple muscle exercise device. The exercising sleeve is disposed to receive the extremities of the human body for stretching and strengthening the muscles.
