Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a flat, springy net surface is used to return the ball, then the device can provide a rebound function, but the return accuracy is insufficient and requires users to spend unnecessary time and energy chasing the ball

Engineering Contradiction:
Improveball return accuracyVSAvoidtime spent chasing ball
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the flat net surface with a curved, conical reflector surface. This curvature allows the reflector to guide the ball along a controlled arc trajectory, improving return accuracy by directing the ball precisely back to the user rather than relying on simple rebound from a flat surface.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The patent employs an adjustable tension mechanism that modifies the physical parameters of the reflector surface. By changing tension, the reflector's shape and elasticity can be adjusted to optimize ball return characteristics for different ball types and user preferences, thereby improving reliability of ball return.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If a fixed design is used for ball return devices, then the structure is simple, but the device is limited in application to one or few sports and has restricted return trajectory

Engineering Contradiction:
Improveapplicability to various sportsVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent incorporates multiple adjustable components including tension mechanisms, rotating bases, and height-adjustable legs. These dynamic elements allow the device to adapt its structure and function for different sports and training scenarios, transforming a static device into a versatile multi-sport tool.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent designs the device with universal applicability across multiple sports through its adjustable reflector angles, variable tension settings, and configurable height. This multi-functionality allows the same device to serve basketball, tennis, soccer, and other ball sports without requiring sport-specific modifications.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A ball return device having a frame and an elastic reflector supported on the frame. The elastic reflector has a first open end that is connected to a rim, and an opposite second end that is downwardly tapered from the first end to form a vertex at the second end. The elastic reflector is connected at the second end to the frame by a tension cord that supplies tension to the elastic reflector. The degree of tension in the tension cord, as well as the location of the attachment point of the tension cord on the frame, are adjustable.
