Weightlifting Strap Handle Layout for Reduced Joint Strain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weightlifting equipment causes strain to users' hands, wrists, and fingers, and is unsuitable for individuals with disabilities, leading to joint overstraining during weightlifting.
Innovation Solution
A weightlifting facilitator strap system that secures dumbbells with non-elastic straps featuring handle openings and a self-fastener mechanism, allowing for multiple grip options and distributing weight for balanced lifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional weightlifting equipment (gloves, resistance bands) is used, then weightlifting can be performed, but strain is caused to the user's hand, wrist, and fingers
Solution Approach 1:
The patent introduces a strap system as an intermediary device between the user's hand and the dumbbell. The strap wraps around the dumbbell handle and provides attachment points for the user's hand, acting as a mediator that transfers the lifting force while reducing direct strain on the user's hand, wrist, and finger joints.
Solution Approach 2:
The strap system segments the lifting function into multiple components: the main strap that secures to the dumbbell, handle openings at different positions, and optional wrist straps. This segmentation allows the user to distribute the lifting effort across different body parts and grip positions, reducing concentration of strain on any single joint.
2Adaptability or versatility
If traditional weightlifting equipment is used, then weightlifting can be performed, but it is not suitable for users with disabilities, leading to joint overstraining
Solution Approach 1:
The strap system is designed with multiple handle openings at different positions and optional wrist strap attachments, making it universally adaptable to various user needs and disability types. Users can select different grip positions and configurations based on their specific physical capabilities, allowing the same device to serve multiple users with different requirements.
Solution Approach 2:
The strap system allows dynamic adjustment of grip positions through multiple handle openings at different heights and distances from the dumbbell center. Users can dynamically change their grip configuration during exercise based on their comfort and ability, enabling adaptive use for users with varying levels of mobility and strength.
