Tackling Bag Cable Shroud Dynamics for Rugby Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tackling apparatuses used in football and rugby training do not accurately simulate live game tackling, leading to unreliable and ineffective player training due to limited player-on-player contact during practice.
Innovation Solution
A tackling apparatus comprising a pair of support members, a cable, a rolling mechanism, and a tackling bag, where the rolling mechanism is connected to the cable and configured to traverse it, with pulley systems and weights providing resistance to simulate live game tackling, and a cable shroud that changes its length upon force application to the bag, ensuring accurate and reliable simulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional tackling apparatuses are used, then player training can proceed without player-on-player contact, but the simulation accuracy of live game tackling deteriorates
Solution Approach 1:
The cable system acts as an intermediary between the fixed support members and the tackling bag, enabling realistic movement and resistance simulation. The cable transmits force from the support members through the rolling mechanism to the bag, creating authentic tackling dynamics without requiring player-on-player contact
Solution Approach 2:
The rolling mechanism transforms the static cable system into a dynamic one, allowing the tackling bag to move freely along the cable while maintaining tension. This dynamic setup replicates the unpredictable movement patterns of live game tackling, improving simulation accuracy while maintaining training reliability
2Ease of operation
If the rolling mechanism is allowed to traverse the cable freely, then the tackling bag can move smoothly, but the mechanism cannot provide resistance when force is applied
Solution Approach 1:
The rolling mechanism transitions from a free-rolling state during setup to a constrained state during tackling. When force is applied to the bag, the mechanism engages with the cable to provide resistance, creating a dynamic system that adapts to operational needs
Solution Approach 2:
The rolling mechanism is designed to preemptively engage with the cable when force is applied, creating resistance before the tackling action completes. This preliminary engagement ensures that the mechanism provides immediate feedback and resistance during the tackling motion
3Stability of the object's composition
If the cable shroud is made rigid to maintain structure, then the apparatus is stable, but it cannot accommodate force application and length changes
Solution Approach 1:
The cable shroud is constructed from flexible material that can stretch and compress in response to applied forces. This flexibility allows the shroud to accommodate the dynamic movements and force applications during tackling while maintaining its structural integrity and guiding the cable properly
Solution Approach 2:
The cable shroud transitions from a static protective covering to a dynamic component that actively responds to force application. The material properties enable the shroud to elongate under tension and return to its original state, providing both stability and adaptability

AI summary
An apparatus includes support members, a cable, a rolling mechanism and a tackling bag. The cable is configured to extend between the support members. The rolling mechanism is configured to traverse the cable and includes first and second sets of wheels. The cable is configured to extend between two wheels of the first set of wheels and between two wheels of the second set of wheels. The tackling bag is configured for attachment to the rolling mechanism. When a downward force is applied to the tackling bag, the pulley device detaches from the wheel housing and a portion of the cable extends around one of the two wheels of the first set of wheels and around one of the two wheels of the second set of wheels to prevent the rolling mechanism from further traversing the cable once the downward force is applied to the tackling bag.
