Stretchable Weight Plate Strap for Secure Low-Bulk Barbell Collars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weight training devices, such as barbells, face issues with heavy and bulky collars that lack durability, are prone to being lost or broken, and do not accommodate all barbell sizes due to limited clamping force, leading to insecure weight plate attachment.
Innovation Solution
A stretchable rubber or rubber-like weight plate securing strap with a post and apertures that forms a circular collar around the barbell, providing a secure and adjustable attachment method for weight plates without adding significant weight or bulk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional metal or plastic collars are used to secure weight plates, then the weight plates are securely attached to the barbell, but the collar adds significant weight and bulk to the barbell assembly
Solution Approach 1:
The patent uses a thin, flexible strap made of nylon webbing or similar material to replace traditional rigid metal or plastic collars. This flexible strap wraps around the barbell sleeve and secures the weight plate with minimal added weight and bulk, while still providing secure attachment through friction and tension.
Solution Approach 2:
The invention extracts the essential securing function from the heavy collar structure, keeping only the necessary strap component that provides security without the excess weight. The strap is a simplified version that removes unnecessary material while maintaining the core function of preventing weight plate detachment.
2Reliability
If traditional collars with multiple parts are used to secure weight plates, then the weight plates are securely attached, but the collar is prone to being lost or broken due to multiple small parts
Solution Approach 1:
The patent merges all the securing functions into a single integrated strap component, eliminating multiple small parts such as screws, springs, or separate locking mechanisms. The strap performs both the securing and locking functions in one continuous piece, reducing the risk of parts being lost or broken.
Solution Approach 2:
The strap is designed as a simple, inexpensive component that can be easily replaced if worn or damaged. Using a basic nylon webbing strap rather than complex metal mechanisms makes it more durable in terms of resistance to breaking, and easier to replace if needed.
3Reliability
If collars with long sleeve length are used to fasten securely, then the weight plates are securely attached, but the apparatus becomes bulky
Solution Approach 1:
The flexible strap can be wrapped around the barbell sleeve multiple times or adjusted to the appropriate length, providing secure attachment without requiring a long fixed structure. The flexibility allows it to conform to the sleeve length needed, minimizing bulk while maintaining security.
4Device complexity
If collars with fixed clamping force are used, then the structure is simple, but the collar does not accommodate all sizes of barbell sleeves equally
Solution Approach 1:
The strap uses a dynamic adjustment mechanism where the user can slide the strap along the barbell sleeve and adjust the tension to accommodate different sleeve diameters. The friction-based holding mechanism allows the strap to adapt to various sizes while maintaining a relatively simple structure without complex springs or adjustable components.
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
The strap offers easy installation and removal, high resistance to weight plate movement, and secure attachment for plates up to 100 pounds, while being lightweight and durable, accommodating various barbell sizes without damaging the equipment.
Implementation Method 1
The nature of the rubber or rubber-like texture of the strap and its being wound stretched around the barbell creates a high resistance to movement along the length of the barbell
Implementation Method 2
The strip is, preferably, stretchable, made of rubber, or is rubber-like

AI summary
A weight plate securing strap having a strip with a first end and a second opposite end. A post is on the first end and a plurality of apertures are near the second opposite end, wherein, when the strap is curved so that the post on the first end is inserted into an aperture near the second opposite end, the strap forms a circular collar for a weight plate on a barbell and wherein the strip is stretchable, made of rubber, or is rubber-like. A gripping flap on the first end and on the second opposite end facilitate installation of the strap around a barbell. The nature of the rubber or rubber-like texture of the strap and its being wound and stretched around the barbell creates a high resistance to movement along the length of the barbell.
