Ergonomic Pull Handle With Sliding Attachment Track
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pull handles in exercise equipment impose unnatural stress on users' joints and limit mobility, causing discomfort and restricting the range of exercises that can be performed, as they do not account for the natural rotation of hands, wrists, and arms during movements.
Innovation Solution
An ergonomic pull handle design featuring one or more axes of rotation and flexibility, allowing for natural movement of the hand, wrist, and arm, and incorporating a movable point of attachment that alleviates discomfort by rotating and sliding along a track, enabling a wider range of exercises.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed point of attachment is used in existing pull handles, then the structure is simple and stable, but the range of mobility is limited and unnatural stress is created on joints
Solution Approach 1:
The pull handle incorporates a movable attachment point that can slide along a curved track, transforming the fixed attachment into a dynamic system. This allows the attachment point to move relative to the handle body, accommodating the natural rotation and movement of the user's hand, wrist, and arm while maintaining structural integrity through guided motion constraints
2Object-affected harmful factors
If a fixed point of attachment is used in existing pull handles, then the manufacturing is simple, but unnatural stress is created on joints, ligaments and tendons
Solution Approach 1:
The movable attachment point sliding along a curved track creates a dynamic system that adapts to natural body movement patterns, eliminating unnatural stress concentrations on joints, ligaments, and tendons while maintaining manageable structural complexity through guided motion constraints
3Ease of operation
If existing pull handle forms are used, then the design is simple, but discomfort is caused during certain exercises
Solution Approach 1:
The curved track mechanism enables the attachment point to move dynamically during exercise movements, allowing the handle to adapt to different exercise positions and angles, thereby eliminating discomfort while maintaining reasonable design complexity
Solution Approach 2:
The curved track geometry is specifically designed to change the position and orientation parameters of the attachment point throughout the range of motion, optimizing comfort for different exercise types while keeping the overall design manageable
4Adaptability or versatility
If existing pull handles are used, then the device is simple, but the type of exercises that can be performed is limited
Solution Approach 1:
The movable attachment point on the curved track creates a dynamic system that can accommodate various exercise movements and angles, significantly increasing exercise versatility while maintaining manageable structural complexity through guided motion constraints
Solution Approach 2:
The curved track mechanism enables a single handle design to support multiple exercise types and movements, achieving multi-functionality without requiring multiple specialized handles, thereby increasing versatility while controlling overall device complexity

AI summary
A pull handle that is ergonomically designed to avoid unnatural stresses and/or discomfort to the user's body and joints through the range of motion. The invention enables a user to perform exercises that cannot be accomplished with existing handles or may be more difficult or uncomfortable to do so. These objects are achieved by providing one or more axes of rotation or flexibility in the pull handle so that the user's hand, wrist and/or arm (or foot, ankle and/or leg) may bend and/or rotate more naturally through the user's range of motion.
