Technique Plate Design for Barbell Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional barbell technique plates with proportionally related weights and diameters result in an unsuitable distance between the barbell and the ground for beginners practicing clean and jerk, leading to potential waist injuries during squats and catches.
Innovation Solution
A technique plate design featuring a dimension ring with a clamping protrusion, clamping disks, and a sleeve, which allows for a lighter weight configuration, increasing the distance between the barbell and the ground by adjusting the clamping mechanism to prevent injuries and promote proper technique.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional technique plates with proportionally related weights and diameters are used, then the barbell structure is simple and standard, but the distance between the barbell and the ground becomes too short (8-10 cm), causing injury risk for beginners
Solution Approach 1:
The patent changes the weight parameter of the technique plate while maintaining the same diameter specification. By reducing the weight from conventional standards to 0.5-2 kg range while keeping the outer diameter at 40-50mm and inner diameter at 25-35mm, the center of gravity shifts upward, increasing the distance between the barbell and ground to prevent beginner injuries during clean and jerk exercises
2Length of moving object
If lighter technique plates are used to increase barbell height, then beginner safety is improved, but the plate structure becomes more complex with dimension rings, clamping disks, and sleeves
Solution Approach 1:
The technique plate is divided into multiple functional segments: a dimension ring providing structural support and diameter control, clamping disks for securing the plate to the barbell, and a sleeve for mounting. This segmentation allows each component to be optimized independently while maintaining overall functionality
Solution Approach 2:
The patent employs composite construction combining metal components (dimension ring, clamping disks, sleeve) with fastening mechanisms. The dimension ring and clamping disks form a composite structure that achieves both weight reduction and structural integrity through material selection and design integration

AI summary
A technique plate in accordance with the present invention has a dimension ring, two clamping disks and a sleeve. The dimension ring has an internal edge, two side surfaces and a clamping protrusion. The clamping protrusion is formed on and protrudes from the internal surface. The clamping disks are mounted on and clamp the clamping protrusion of the dimension ring. Therefore, compared to a conventional technique plate of the same diameter, the technique plate of the present invention is lighter, so the distance between a bar of a barbell and the ground is higher to prevent beginner's injury.
