Solution Overview

Problem

Existing golf bag transport solutions, such as pull carts and electric carts, are not compact, stable, convenient, or lightweight, and often damage golf course turf, limiting their usability and convenience for golfers.

Innovation Solution

A pedal-powered, motor-assisted riding golf bag cycle that is symmetrical, collapsible, and steerable, with a minimal footprint, featuring a frame, personal support, wheel assemblies, and a motor-assist system, allowing easy transport and storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If traditional pull carts or electric carts are used, then golf bags can be transported, but the carts are not compact, stable, or lightweight and often damage golf course turf

Engineering Contradiction:

Improveturf damageVSAvoidconvenience

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent replaces traditional mechanical cart systems with a gyroscopic two-wheeled balancing system that uses rotational momentum and computer control to maintain stability and navigate terrain without damaging turf

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention changes the operational parameters by using dynamic balance control and adaptive steering mechanisms that adjust to terrain conditions, allowing the cart to operate on grass surfaces without the harmful mechanical contact of traditional carts

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If riding carts are used, then rider comfort is improved, but the carts have large footprint and are not compact for storage

Engineering Contradiction:

Improverider comfortVSAvoidfootprint

Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

The patent employs dynamic balancing technology that allows the two-wheeled cart to maintain stability in a compact configuration, enabling rider comfort without requiring the large static footprint of traditional riding carts

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The gyroscopic system provides self-balancing capability, allowing the cart to maintain its riding position and stability automatically without requiring additional support structures that would increase its footprint

Inventive Principle:

Principle #25Self-service

3Productivity

If pedal-powered carts are used, then exercise benefits are provided, but the carts lack sufficient power for difficult terrain

Engineering Contradiction:

Improveexercise benefitVSAvoidpower assist

Core Design Contradiction:

ProductivityVSPower

Solution Approach 1:

The patent creates a multi-functional system that combines pedal-powered exercise capability with electric motor assistance, allowing the cart to provide both health benefits and sufficient power for various terrain conditions

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention introduces an electric motor as an intermediary power source that supplements pedal power, enabling the system to deliver both exercise benefits and adequate power for difficult terrain without relying solely on human effort

Inventive Principle:

Principle #24Intermediary (Mediator)
