Solution Overview

Problem

Existing golf bag designs may fail to deploy their legs properly on uneven or irregular ground surfaces, leading to instability and difficulty in supporting the bag.

Innovation Solution

A golf bag design featuring a frame with a manipulation member installed on the upper portion and a transmission member extending along the side edge of the opening, allowing the legs to be easily switched from a standby to a deployed position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the pressing member is installed on the bottom to automatically open legs when tilted, then the legs can be deployed on flat ground, but the legs fail to deploy reliably on uneven ground where the pressing member is not sufficiently pressed

Engineering Contradiction:
Improveleg deployment reliabilityVSAvoidmanual leg deployment
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The manipulation member allows the user to manually activate the transmission member, which then automatically actuates both legs simultaneously. This hybrid approach combines manual initiation with automatic execution, solving the reliability issue on uneven ground while maintaining ease of operation through simple manual input.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The transmission member acts as an intermediary mechanism between the manipulation member and the legs. It transmits the user's manual input to both legs, ensuring synchronized and reliable deployment regardless of ground conditions, thereby overcoming the limitation of direct pressing member activation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the transmission member is installed across the opening to connect legs, then the legs can be switched simultaneously, but the opening is narrowed

Engineering Contradiction:
Improvesimultaneous leg switchingVSAvoidopening area
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The transmission member is routed along the side edge of the opening rather than across it, changing the spatial dimension of the transmission path. This allows the transmission member to connect both legs and enable simultaneous switching while preserving the full opening area for club insertion and removal.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The design enables users to easily deploy the legs of the golf bag, ensuring stability on various ground conditions without narrowing the opening of the bag, thus facilitating easy storage and use.

Implementation Method 1

a support member (stand) rotatably connected to the frame... a pressing member rotatably installed on the bottom... an elastic member, which in turn rotates the support member to protrude from the frame

AI summary

A golf bag includes a golf bag body into which a golf club is inserted; a frame body supporting the golf bag body with an opening of the golf bag body located on an upper side; a pair of legs rotatably supported on one side of the frame body to switch between a stand-by position and a deployed position where the pair of legs are capable of supporting the frame body; a manipulation member installed at the upper portion of another side of the frame body so as to be switchable in a predetermined direction; and a transmission member at least partially extending along a side edge of the opening, so that the legs can be switched from the stand-by position to the deployed position by switching the manipulation member.
