Innovation Solution

A remotely controlled ball picking machine equipped with a frame mechanism, suction mechanism, sensors, and a controller that allows for automated movement, ball collection, and foreign object separation, enabling efficient and controlled ball collection without manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual ball collection is used, then simplicity of device is maintained, but labor intensity increases and collection efficiency decreases

Engineering Contradiction:
Improveball collection efficiencyVSAvoidmanual labor intensity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The ball picking machine autonomously navigates to ball locations, detects balls using sensors, and collects them using a suction mechanism without requiring human operators to physically move or position collection devices, thereby eliminating manual labor while maintaining high collection efficiency

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical collection methods with an automated system that uses sensors for detection, a controller for decision-making, and a suction mechanism for ball collection, substituting human physical effort with automated mechanical and electronic systems

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Extent of automation

If automated ball picking machine is deployed, then labor intensity is reduced, but device complexity increases

Engineering Contradiction:
Improveautomation levelVSAvoidsystem complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The automated ball picking system is divided into distinct functional modules: a moving unit for navigation, a sensing unit with multiple sensors for ball detection, a controller for coordination, and a suction mechanism for collection. This segmentation allows each component to perform its specific function independently while working together as an integrated system, managing complexity through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The moving unit serves multiple functions by both navigating to ball locations and positioning the suction mechanism for collection. The controller coordinates all components including movement, sensing, and suction operations, consolidating control functions to manage system complexity through multi-functional integration

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

3Productivity

If ball collection continues without monitoring, then collection speed is maintained, but ball overflow and foreign object contamination increase

Engineering Contradiction:
Improvecollection speedVSAvoidball collection accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The sensing unit continuously monitors the collection box to detect when it is full or when foreign objects are present. This feedback information is sent to the controller, which automatically stops the collection process when necessary, preventing overflow and contamination while maintaining high collection speed during normal operation

Inventive Principle:
Principle #23Feedback

AI summary

A ball picking machine (200) is adapted for picking ball bodies (901) by remote control, and includes a moving unit (31), a suction device (42), a ball overflow sensor (51), a controller (8), and a collection box unit (32) that defines a ball collecting space (323). The ball overflow sensor (51) generates a full-ball signal when a height of the ball bodies 901 that accumulate in the ball collecting space (323) is greater than a predetermined height. The controller (8) is signally connected to the moving unit (31), the suction device (42), and the ball overflow sensor (51), and includes a communication module (81) and a control module (82). The control module (82) turns off the suction device (42) and sends a full-ball message outwardly through the communication module (81) when triggered by the full-ball signal.
