Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the punching bag uses a fixed integrated base structure, then the support stability is improved, but the transportation cost and storage convenience deteriorate due to large size and weight
Solution Approach 1:
The base is divided into multiple detachable support legs that can be separated from the punching bag body. Each support leg can be independently stored or transported, reducing the overall size and weight during transit while maintaining stability during use through the multi-leg configuration
Solution Approach 2:
The support legs are designed to be movable and adjustable rather than fixed. They can be extended or retracted, and their positions can be adjusted to optimize both storage compactness and operational stability, allowing the structure to adapt between transport and use states
2Ease of manufacture
If the punching bag uses a movable structure with detachable base, then the transportation cost and storage convenience are improved, but the support stability deteriorates
Solution Approach 1:
Different parts of the base structure have different properties - the connection points between support legs and the punching bag body are designed with reinforcement rings and welding structures to maintain local stability, while other parts remain flexible and detachable for easy transport
Solution Approach 2:
The punching bag body and base are made of elastic materials (such as Hypalon) that provide both flexibility for movement and structural integrity for stability. The combination of elastic material properties with the multi-leg geometry creates a structure that is both movable and stable
3Volume of moving object
If the punching bag body and base are made of elastic materials, then the foldability and storage space are improved, but the hardness and support strength deteriorate
Solution Approach 1:
The support legs contain inflation cavities and water injection cavities that can be filled with air or water to increase hardness. The elastic isolation layer separates these cavities, allowing independent control of inflation to adjust the hardness and support strength of each leg as needed
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 reduces transportation costs and space occupation while providing improved support stability and combat simulation through elastic deformation and water compression, enhancing the training experience.
Implementation Method 1
the elastic isolation layer is deformed towards the water injection cavity to gradually compress water in the water injection cavity
Implementation Method 2
compress water in the water injection cavity, and at this time, a hardness of the water injection cavity is greatly increased
Implementation Method 3
the punching bag body is weldedly connected with the base by hot melting
Implementation Method 4
the elastic isolation layer is welded with an inner wall of each of the plurality of support legs by hot melting

AI summary
A multi-leg movable punching bag includes a punching bag body and a base. An interior of the punching bag body is communicated with an interior of the base, and the punching bag body and the base are both hollow. The punching bag body is welded with the base by hot melting. The punching bag body and the base are both made of an elastic material. The base includes a plurality of support legs, and any two adjacent support legs are arranged at a fixed angle. The punching bag body and the base are both made of an elastic material so that the they can be folded and stored when the punching bag is not in use.
