Solution Overview

Problem

Conventional golf bags with reduced storage space for a few clubs lack reliable portability and convenience, especially when a golfer carries them without a caddy, particularly during approach shots or on public courses.

Innovation Solution

A compact golf bag design featuring a tubular main body frame, a foldable or rollable pocket, and a detachable handle, along with optional support legs, allowing for easy carrying and minimal storage volume when not in use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a golf bag is designed with sufficient storage space for a full set of golf clubs, then the storage capacity is improved, but the size and weight of the golf bag increase

Engineering Contradiction:
Improvestorage capacityVSAvoidweight of golf bag
Core Design Contradiction:
Quantity of substanceVSWeight of moving object

Solution Approach 1:

The golf bag employs a telescopic main body frame that can extend and retract. When clubs are stored, the frame extends to provide sufficient storage space. When not in use or when carrying only a few clubs, the frame retracts to minimize size and weight, thus resolving the contradiction between storage capacity and portability

Inventive Principle:
Principle #15Dynamics

2Weight of moving object

If a half golf bag is designed with smaller size, then the portability is improved, but the storage space is reduced

Engineering Contradiction:
ImproveportabilityVSAvoidstorage space
Core Design Contradiction:
Weight of moving objectVSQuantity of substance

Solution Approach 1:

The telescopic main body frame allows the bag to dynamically adjust its size. In compact mode, it provides portability similar to a half golf bag. When needed, it can extend to provide adequate storage space, thus resolving the contradiction between portability and storage space

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If the main body frame is made rigid to maintain structure, then the structural stability is improved, but the foldability and compactness are reduced

Engineering Contradiction:
Improvestructural stabilityVSAvoidfoldability
Core Design Contradiction:
Stability of the object's compositionVSShape

Solution Approach 1:

The main body frame uses a telescopic design with segments that can extend and retract while maintaining structural integrity. The frame includes reinforcement ribs that provide structural stability when extended, yet the entire frame can be folded or collapsed into a compact form when not in use, resolving the contradiction between structural stability and foldability

Inventive Principle:
Principle #15Dynamics

AI summary

Disclosed is a golf bag having a minimum volume when not in use. The golf bag includes a main body frame (10) having a tubular shape and a pocket (50) made of a foldable or rollable material, the pocket being connected to a lower portion of the main body frame and being configured to support a golf club stored therein through the main body frame, and a handle (30) detachably installed on one side of the main body frame (10) and configured to be held by a user or hung on a device of a golf cart. The golf bag further includes a support (40) detachably coupled to the main body frame and configured to support the main body frame such that the main body frame is in a state of being spaced apart from the ground.
