Counterweight Bag for Hitting Trainer Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hitting trainers struggle to maintain stability on uneven ground while being convenient for movement and storage, as the suction-based systems are ineffective on such surfaces.
Innovation Solution
A counterweight device featuring an annular counterweight bag with telescopic portions that can be extended or compressed, allowing it to be securely attached to the trainer for stability and easily detached for storage, utilizing liquid to increase weight and maintain balance on uneven terrain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a hollow base with large volume is used to firm the base, then the hitting trainer is stable, but it is inconvenient for movement and storage
Solution Approach 1:
The base is divided into two functional parts: a small rigid base unit for portability and a separate counterweight bag for stability. The counterweight bag can be detached and filled with water or other materials to provide stability only when needed, while the base itself remains compact for easy movement and storage.
Solution Approach 2:
The stability of the hitting trainer is dynamically adjusted by changing the weight parameter through the counterweight bag. The bag can be filled with water or other materials to increase weight and improve stability on uneven ground, then emptied or removed when stability is not needed, allowing the base to be lightweight and portable.
2Stability of the object's composition
If a sucking disc unit is used to attach to the ground, then the hitting trainer is stable and convenient for storage, but it cannot be effectively attached to uneven ground
Solution Approach 1:
The counterweight bag acts as a counterweight device that compensates for the effects of uneven ground. By filling the bag with water or other materials, weight is added to the base, creating a lower center of gravity and improving stability on uneven surfaces without requiring suction or complex attachment mechanisms.
3Stability of the object's composition
If the counterweight bag is extended to increase volume, then the hitting trainer is stable on uneven ground, but the counterweight bag occupies more space for storage
Solution Approach 1:
The counterweight bag is designed as a separate, detachable component from the base. When not in use, the bag can be removed from the base, compressed to minimize its volume, and stored separately or attached in a compact state. This segmentation allows the stability function to be added only when needed without permanently increasing the storage volume of the base unit.
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 counterweight device ensures stability on uneven ground and facilitates convenient storage and transport by adjusting volume based on usage needs, effectively addressing the limitations of previous systems.
Implementation Method 1
The inner annular wall and the outer annular wall each have a plurality of spaced telescopic portions for the counterweight bag to be extended or compressed
Implementation Method 2
external liquid is poured into the accommodation room through the water inlet to increase the weight of the counterweight bag

AI summary
A counterweight device is mounted to a hitting trainer. The hitting trainer includes a base, an upright rod disposed on the base, and a hitting member connected to the upright rod. The counterweight device includes a counterweight bag which can be extended or compressed. When in use, the counterweight bag is fitted on the base and then the counterweight bag is pulled to unfold. Finally, external liquid is poured into the counterweight bag to increase the weight of the counterweight bag, such that the hitting trainer can be placed on the uneven ground stably. When the counterweight device is not used, the counterweight bag is detached from the hitting trainer and compressed to reduce the volume of the counterweight bag for storage and carrying.
