Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional ball-returning systems are used, then balls can be returned, but the structure becomes complex and difficult to use
Solution Approach 1:
The ball-returning net is divided into separate functional components: a vertical net for intercepting balls, a slope net for guiding them down, side barrier nets for preventing sideways deflection, and a floor net for catching balls. This segmentation allows each component to perform its specific function independently, simplifying the overall system while maintaining effectiveness.
Solution Approach 2:
The patent extracts and removes unnecessary complex mechanisms from conventional ball-returning systems, retaining only the essential net structures and support frames. By taking out overly complicated components and replacing them with simple net-and-frame constructions, the system achieves ease of operation while reducing structural complexity.
2Productivity
If conventional ball-returning systems are used, then balls can be returned, but they become difficult to collect and manage
Solution Approach 1:
The slope net introduces a dimensional element by creating an inclined surface that guides balls from the vertical net downward toward the user. This dimensional change in the net configuration enables automatic ball return without requiring complex mechanical collection systems, thereby improving productivity while maintaining simplicity.
Solution Approach 2:
The ball-returning net system is designed to automatically intercept, guide, and return balls to the user through its geometric configuration. The vertical net intercepts balls, the slope net automatically directs them down, and the floor net collects them, creating a self-service system that improves ball collection efficiency without requiring complex external mechanisms.
3Reliability
If a sturdy structure is used to prevent ball deflection, then ball management improves, but the structure becomes more complex
Solution Approach 1:
Instead of using a complex overall structure, the patent applies local quality by positioning specific net components at critical locations: the vertical net at the intercept point, the slope net at the guidance angle, and side barrier nets at the edges. Each local component is simple in design but strategically positioned to prevent ball deflection and ensure reliable return, avoiding the need for complex structural systems.

Function Achieved in This Case
The system provides a simple, sturdy, and efficient means to manage balls, saving time and reducing stress during practice by effectively guiding balls back and preventing deflections, while being easy to assemble and disassemble.
Implementation Method 1
a slope net disposed over the floor wire frame so as to be tilted from an elevated lower portion of the vertical net to a front edge portion of the floor wire frame, so as to be configured that a ball hitting the vertical net falls down on the slope net and rolls down in a direction of the front edge portion of the floor wire frame

AI summary
A ball-returning net comprises a vertical wire frame, a vertical net, a floor wire frame, a slope net, two side barrier nets, and a detachable strap. The vertical net is fixed to the edge portion of the vertical wire frame and blocking the opening of the vertical wire frame. The slope net is disposed over the floor wire frame so as to be tilted from an elevated lower portion of the vertical net to a front edge portion of the floor wire frame, so as to be configured that a ball hitting the vertical net falls down on the slope net and rolls down in a direction of the front edge portion of the floor wire frame. The detachable strap holds the slope net and the vertical wire frame tightly, bending a rear portion of the slope net in a V shape.
