Solution Overview

Problem

Existing ball collecting systems require workers to manually lift heavy loads of balls from a pit, increasing workload and labor intensity.

Innovation Solution

A ball collecting system that allows workers to move baskets containing balls horizontally, reducing the need to lift them, using a configuration with sloping surfaces and a distribution structure to guide balls into multiple baskets, ensuring even weight distribution and easy transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If golf balls are left on the green after putting, then they may be lost or stolen, but collecting them manually increases labor time and reduces efficiency

Engineering Contradiction:
Improveball recovery rateVSAvoidtime to collect balls
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system enables automatic ball recovery through sensors that detect when a ball has been putted and mechanically retrieve it without human intervention. The ball retrieval mechanism automatically activates when a ball crosses the putting line, transports it to the collection area, and resets without requiring manual collection by staff.

Inventive Principle:
Principle #25Self-service

2Difficulty of detecting and measuring

If ball markers are placed on the green to indicate ball locations, then balls can be located more easily, but it adds complexity to the system setup and maintenance

Engineering Contradiction:
Improveball location detectionVSAvoidmarker system complexity
Core Design Contradiction:
Difficulty of detecting and measuringVSDevice complexity

Solution Approach 1:

The system replaces manual ball markers with an electronic sensor network embedded in the green. Optical or electromagnetic sensors detect ball positions automatically through the putting surface, eliminating the need for physical markers and their associated setup and maintenance complexity.

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

3Productivity

If a ball retrieval mechanism is installed on the green, then balls are automatically collected improving efficiency, but it increases device complexity and installation cost

Engineering Contradiction:
Improveball collection efficiencyVSAvoidretrieval system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The ball retrieval mechanism is integrated with the existing putting green infrastructure and ball storage systems. The retrieval mechanism combines sensing, transport, and storage functions into a unified system that works seamlessly with the course layout, reducing overall complexity compared to separate independent systems.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A ball collecting system 1 comprises a picker 2, and a pit 5 configured to enable balls BL discharged from the picker 2 to be collected in a ball-collecting space 51. At least one basket BS whose upper part is open is disposed in the ball-collecting space 51 to allow the discharged balls BL to be dropped and stored in the basket BS. The ball-collecting space 51 is configured such that one end thereof in a horizontal direction is formed as an open zone, to allow the basket BS to be taken out from the ball-collecting space 51 through the open zone 52.
