Weight Lifting Shirt Grid Plate Energy Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bench press shirts restrict proper range of motion and depth during weightlifting, require assistance for proper bar path, and do not effectively transfer load and energy to reduce strain on the rotator cuffs and shoulder girdle.
Innovation Solution
A weight lifting support shirt with a chest support portion, arm support portions, neck relief portion, torso support portion, and lateral extensions made of elastic material, featuring a grid plate and hook and loop fasteners, designed to store and release energy to assist in lifting weights while stabilizing the shoulder and shoulder girdle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If prior art bench shirts use narrower arm sleeve angles and looser chest regions, then the shirt structure is simpler, but the lifter cannot follow a proper bar path and requires spotter assistance
Solution Approach 1:
The shirt incorporates dynamic geometric configurations with adjustable arm sleeve angles and chest regions that adapt during the bench press movement. The sleeves and chest pieces are designed to move and adjust their orientation relative to each other, allowing the shirt to dynamically accommodate the proper bar path while maintaining structural support.
2Use of energy by moving object
If prior art bench shirts use resilient material that stretches across the chest, then energy storage is achieved, but the lifter experiences strain on rotator cuffs and shoulder girdle
Solution Approach 1:
The shirt distributes energy storage and load bearing across multiple localized regions including chest pieces, arm sleeves, and back pieces rather than relying on a single stretching chest plate. Each component is optimized for its specific location, with the back pieces and lateral extensions providing additional support points that reduce concentrated stress on the rotator cuffs and shoulder girdle.
Solution Approach 2:
The shirt combines multiple resilient material components (chest pieces, arm sleeves, back pieces, lateral extensions) working together as a composite system. This distributed composite structure provides energy storage while spreading mechanical loads across broader anatomical regions, reducing strain on vulnerable areas like the rotator cuffs.
3Reliability
If prior art bench shirts require spotter assistance for proper positioning, then safety is improved, but the operation requires external help and loses time
Solution Approach 1:
The shirt is designed with self-adjusting geometric configurations and elastic properties that automatically position the lifter's arms and torso into the correct bench press alignment. The resilient materials and structured pieces work together to guide proper body positioning without requiring external assistance from a spotter, enabling the lifter to independently achieve and maintain proper form.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables proper range of motion and depth during weightlifting, transfers load and energy effectively to the chest and arms, reducing strain on the rotator cuffs and stabilizing the shoulder girdle, allowing for efficient and comfortable lifting of weights without external assistance.
Implementation Method 1
The neck relief portion comprises elastic material that stretches to store energy when a weight is lowered by the lifter. The elastic material of the neck relief portion releases the stored energy and returns to an unstretched state of the elastic material when the weight is raised by the lifter
Implementation Method 2
As the user lowers the weighted bar, the chest plate and sleeves stretch between the user's shoulders and across the chest of the user. The stretching, resilient material of the bench shirt stores energy when the weight is lowered and applies a force in the upward direction to the upper arm of the user proximal to the user's shoulder to counter the downward force of the weighted bar

AI summary
A weight lifting support shirt includes a chest support portion, a first arm support portion, a second arm support portion, a neck relief portion, a torso support portion, a first lateral extension, and a second lateral extension. A grid plate is disposed about a center of the chest support portion. The grid plate resists stretching of material of the chest support portion when a weight is lowered by a lifter and stores energy of the weight when the weight is lowered during a workout. The grid plate rebounds the stored energy into a chest portion and arms of the lifter when the weight is lifted by the lifter during the workout. The grid plate comprises a figure eight stitching. The figure eight stitching directs load and energy received from multiple angles during the workout, towards the center of the chest support portion.
