Solution Overview

Problem

Existing training devices do not effectively utilize a chest worn harness with resiliently stretchable bands to restrict and position a runner's arms for proper running form.

Innovation Solution

A training device comprising a chest worn harness with a pair of arm cuffs tethered to each side via resiliently stretchable bands, which draw the arms towards the harness to restrict movement and promote proper running form.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If nonelastic straps are used to limit arm range of motion, then arm movement is restricted, but the device cannot dynamically adapt to running form variations

Engineering Contradiction:

Improveadaptability to running formVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent changes the physical parameter of the connecting element from nonelastic to resiliently stretchable, allowing the band to dynamically adjust its length and tension based on arm position and running form, providing adaptability without complex mechanical adjustments

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The resiliently stretchable bands introduce dynamic behavior to the device, allowing it to adapt to varying arm positions and running forms during exercise, transforming a static restriction device into a dynamic training aid

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If resiliently stretchable straps are used for muscle strengthening, then dynamic movement is allowed, but arm positioning control is insufficient for proper running form

Engineering Contradiction:

Improveease of useVSAvoidarm positioning control

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The patent applies different qualities to different parts of the device: the bands provide elasticity for comfort and range of motion, while the cuffs provide localized constraint at the wrists to maintain proper arm positioning, combining ease of movement with positioning control

Inventive Principle:

Principle #3Local quality

3Reliability

If arms are restricted toward the harness, then proper running form is promoted, but arm movement freedom is reduced

Engineering Contradiction:

Improvetraining effectivenessVSAvoidmovement restriction

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The device applies partial restriction rather than complete immobilization, allowing necessary arm movement for natural running while providing enough guidance to maintain proper form, avoiding excessive restriction that would harm comfort and effectiveness

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A running form training device for training a runner to properly position and move their arms includes a harness, a pair of bands, and a pair of cuffs. The harness can be donned by a user so that the harness is removably engaged to a torso of the user. The bands are resiliently stretchable. Each band is engaged to the harness so that the band extends from proximate to a front of a respective shoulder of the user. Each cuff is engaged to a first end of a respective band and is removably engageable to a respective wrist of the user. The bands draw the arms of the user toward the harness, thereby restricting movement and positioning of the arms to promote proper running form.
