Adjustable Sleeve Support Shirt for Weightlifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bench press shirts with taut, inelastic materials pose difficulties in donning and doffing due to their tightness, requiring assistance and compromising between support and ease of use.
Innovation Solution
An adjustable support shirt with longitudinally extending adjustable members, such as laces, zippers, or hook and loop fasteners, that allow for easier ingress and egress while maintaining shoulder and chest support during lifting activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the shirt is made of taut, inelastic materials with high tensile strength to provide support, then the support for lifting is improved, but the difficulty of donning the shirt increases
Solution Approach 1:
The patent applies the dynamics principle by making the sleeve openings adjustable through zippers, laces, or elastic materials. This allows the shirt to transition between a tight, supportive state during lifting and a looser, easier-to-don state during dressing. The adjustable members enable the sleeve opening circumference to be modified, resolving the contradiction between needing tightness for support and requiring looseness for ease of donning.
2Reliability
If the shirt is made tight to provide support during lifting, then the support and safety are improved, but the time required to don the shirt increases
Solution Approach 1:
The adjustable members (zippers, laces, elastic materials) allow the shirt to dynamically adapt its tightness. During donning, the sleeve openings can be loosened to reduce the time required. Once dressed, the adjustments are secured to provide the tight, supportive fit needed for safety during lifting activities.
3Strength
If the shirt is made tight to provide support during lifting, then the support is improved, but the effort required to put on and take off the shirt increases
Solution Approach 1:
The patent employs adjustable members that allow dynamic modification of the sleeve opening circumference. When loosened, the effort required to don and doff the shirt is significantly reduced. When tightened, the shirt provides the necessary support during lifting activities.
4Strength
If the shirt uses taut, inelastic materials to provide support, then the tensile strength is improved, but the ease of manufacture decreases
Solution Approach 1:
The patent segments the shirt into distinct components: the main body made of taut, inelastic material for support, and the sleeve openings with adjustable members for ease of donning. This segmentation allows each component to be optimized independently - the body for tensile strength and the sleeve openings for manufacturability and adjustability.
Solution Approach 2:
The shirt combines different materials and structures - taut inelastic material for the body and adjustable members (zippers, laces, elastic materials) for the sleeve openings. This composite approach allows the shirt to achieve both high tensile strength for support and ease of manufacture through modular components.

AI summary
An adjustable support shirt comprising a shirt body and a pair of shirt body sleeves positioned adjacent to an upper portion of the shirt body is provided. The sleeves include a first end attached to the shirt body at sleeve body holes and a second end having a sleeve opening circumference. Each of the sleeves includes at least one adjustable member which extends generally longitudinally along at least a portion of the sleeves. The at least one adjustable member is adapted to increase or decrease the sleeve opening circumference.
