Solution Overview

Problem

Existing robotic golf caddies lack the ability to autonomously follow a golfer while avoiding collisions with objects and unauthorized locations on a golf course, as they rely on primitive navigation and collision avoidance systems.

Innovation Solution

An autonomous robotic golf caddy equipped with a receiver arrangement, processor unit, sensors, and drive mechanism that uses radio, ultrasonic, or infrared signals to track a golfer and navigate, incorporating LIDAR, ultrasonic, and ultra-wide band sensors for collision avoidance and navigation, allowing it to maintain a predetermined distance and avoid obstacles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If a human caddy carries golf clubs and equipment, then the golfer can have all necessary equipment available, but the golfer's mobility and speed are limited by the caddy's physical capacity

Engineering Contradiction:
Improvegolfer's movement speedVSAvoidcaddy system complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The patent replaces the human caddy's mechanical carrying system with an automated robotic system. The robotic caddy uses sensors, processors, and automated mechanisms to transport clubs and equipment, eliminating the need for human physical effort and enabling faster, more consistent movement throughout the golf course.

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

Solution Approach 2:

The robotic caddy is designed to autonomously perform tasks without human intervention. It automatically follows the golfer, identifies required clubs using image recognition, retrieves them from storage, and delivers them to the golfer, creating a self-service system that operates independently.

Inventive Principle:
Principle #25Self-service

2Productivity

If a human caddy manually retrieves and delivers clubs, then the golfer receives assistance, but the process is slow and inefficient

Engineering Contradiction:
Improveclub retrieval efficiencyVSAvoidtime for club retrieval
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The robotic caddy performs preliminary actions by pre-organizing clubs in the storage compartment according to their likely usage sequence and maintaining readiness for immediate retrieval. This preliminary preparation enables rapid response when the golfer needs a club, eliminating search and manual organization time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system maintains continuous useful action through the automated conveyor mechanism and robotic arm, which can continuously retrieve and deliver clubs without interruption. The golfer's mobile device continuously communicates club needs to the system, ensuring uninterrupted service throughout the round.

Inventive Principle:
Principle #20Continuity of useful action

3Adaptability or versatility

If traditional caddies are used, then golfers have equipment support, but the experience lacks personalization and real-time assistance

Engineering Contradiction:
Improvepersonalization capabilityVSAvoidsystem technology complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The robotic caddy incorporates feedback loops where sensors detect the golfer's club usage, the image recognition system identifies club types, and the mobile device communicates preferences and requirements. This continuous feedback enables the system to adapt and personalize service to each golfer's specific needs and playing style.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system achieves universality by integrating multiple functions into a single platform: club storage, image recognition, automated retrieval, navigation, communication, and personalized service. This multi-functional design allows the same system to serve different golfers with varying needs while maintaining a unified technological architecture.

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