Exercise Device Handle Assembly with Rotational Track Follower

Solution Overview

Problem

Conventional resistance training equipment often imposes unnatural stresses on joints, tendons, and ligaments due to fixed points of attachment, limiting movement and potentially causing injury.

Innovation Solution

An exercise device with a device frame and handle assembly that includes a track follower formation for movement along a curved device track, allowing rotational and pivotal motion, and connectors for adjustable orientation to accommodate various exercises and reduce stress on the user's body.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed point of attachment is used in conventional handles, then the structure is simple and stable, but the range of movement is limited and unnatural stresses are imposed on joints

Engineering Contradiction:

Improverange of movementVSAvoidhandle structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The handle assembly incorporates a rotation mechanism that allows the handle to dynamically adjust its orientation during exercise movements. The handle can rotate about an axis perpendicular to the plane of movement, enabling it to adapt to the user's hand and wrist rotation throughout the range of motion, thereby maintaining natural joint alignment while performing resistance training exercises.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a fixed handle design is used, then manufacturing is simple, but it cannot accommodate different exercises or user preferences

Engineering Contradiction:

Improveexercise varietyVSAvoidhandle assembly

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The handle assembly incorporates a rotation mechanism that allows the handle to dynamically adjust its orientation during exercise movements. The handle can rotate about an axis perpendicular to the plane of movement, enabling it to adapt to the user's hand and wrist rotation throughout the range of motion, thereby maintaining natural joint alignment while performing resistance training exercises.

Inventive Principle:

Principle #15Dynamics

3Reliability

If conventional fixed handles are used, then the device is simple to operate, but injury risk increases due to unnatural joint stresses

Engineering Contradiction:

Improveinjury preventionVSAvoidoperation simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The handle assembly incorporates a rotation mechanism that allows the handle to dynamically adjust its orientation during exercise movements. The handle can rotate about an axis perpendicular to the plane of movement, enabling it to adapt to the user's hand and wrist rotation throughout the range of motion, thereby maintaining natural joint alignment while performing resistance training exercises.

AI summary

An exercise device includes a device frame for operative coupling to a load during a strength training exercise. The device frame defines a device track and a handle assembly for operative attachment to the device frame. The handle assembly including a hand grip to be held by a user during the strength training exercise, and a track follower formation attached to the hand grip. The track follower formation is operatively adapted for movement along the device track during the strength training exercise.
