Throw Weight Bag Hole Design for Velocity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional indoor weight throw equipment limits the velocity of the thrown weight due to the closed bag design, restricting the distance athletes can throw.
Innovation Solution
A throw weight design featuring a handle, a connector, and a bag with a hole at the end opposite the handle, allowing the weight to partially expose and move further away from the athlete during rotation, enhancing velocity and distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the bag is designed with a closed end, then the weight is contained securely, but the velocity and throwing distance are limited
Solution Approach 1:
The patent extracts the end closure from the bag design by introducing a hole at one end, allowing the weight to partially exit the bag during rotation. This extraction enables the weight to extend beyond the bag's boundary, increasing the effective throwing radius and velocity without compromising the bag's structural integrity during the throwing motion.
2Length of moving object
If the weight is fully enclosed in the bag, then the bag structure is simple, but the weight cannot move further away from the athlete during rotation
Solution Approach 1:
The patent segments the bag structure into multiple components: the bag body, the hole at the end, and the connector system. This segmentation allows the weight to interact with both the bag (for secure attachment during rotation) and the external environment (by extending through the hole), effectively increasing the throwing distance while managing structural complexity through modular design.
3Speed
If the weight is allowed to partially expose through the hole, then velocity and distance increase, but the weight may become unstable
Solution Approach 1:
The connector acts as an intermediary element between the bag and the weight, providing a controlled interface that allows the weight to extend through the hole while maintaining secure attachment. This intermediary connection stabilizes the weight's position during rotation, preventing excessive movement or detachment while still enabling the velocity and distance benefits of partial exposure.
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 design enables greater velocity and distance in weight throwing by allowing the weight to partially penetrate the bag's hole, surpassing conventional throw weights with closed ends.
Implementation Method 1
an athlete grabs the handle, and rotates his/her body several times to increase a velocity of the throw weight. Once the athlete achieves a sufficient angular velocity, the athlete lets go of the throw weight.

AI summary
A throw weight includes a handle and a bag rotatably associated with the handle. The bag is designed to hold a weight which can be interchanged with other weights. The bag and handle are particularly constructed and oriented relative to one another for the purpose of correctly stabilizing the weight and to facilitate ease of throwing. The bag may include an opening at an end of the bag opposite the handle.
