Golf Bag Crush Zone Structure for Anti-Tangle Club Access

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing golf bags with ground-flush bases experience club tangle due to fabric bunching and constriction when the legs are extended, making it difficult to remove individual clubs without resistance or pulling multiple clubs.

Innovation Solution

The golf bag incorporates a crush zone in the fabric flat that collapses outward, a base with a tall ring to prevent inward folding, and a reinforced divider sleeve to maintain club positions, along with dividing ribs to reduce shifting during deployment and retraction of the stand assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the legs are extended to support the bag in a deployed position, then the bag can stand freely and provide easy access to clubs, but the fabric bunches up near the base causing club tangle

Engineering Contradiction:

Improveease of access to clubsVSAvoidclub tangle

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The base is divided into a first base portion and a second base portion that can move relative to each other. The second base portion is configured to move away from the first base portion in response to leg extension, creating space that prevents fabric bunching and club tangling while maintaining ground-flush contact.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The second base portion is made movable relative to the first base portion, allowing the base structure to dynamically adapt to the deployed position. This movement accommodates the fabric redistribution that occurs during leg extension, preventing harmful fabric bunching.

Inventive Principle:

Principle #15Dynamics

2Object-affected harmful factors

If a rigid base is used to prevent fabric bunching, then club tangle is reduced, but the base lifts partially off the ground reducing stability

Engineering Contradiction:

Improvefabric bunchingVSAvoidbase stability

Core Design Contradiction:

Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The base is segmented into two portions where the second portion can move independently. This allows the base to maintain ground contact (first portion) while creating internal space (second portion movement) to prevent fabric bunching, achieving both stability and tangle prevention.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different portions of the base have different functions: the first base portion maintains ground contact for stability, while the second base portion moves to prevent fabric bunching. This local differentiation resolves the contradiction between stability and tangle prevention.

Inventive Principle:

Principle #3Local quality

3Stability of the object's composition

If the base is designed to remain completely flush against the ground, then stability is maintained, but fabric bunching occurs causing club tangle

Engineering Contradiction:

Improvebase stabilityVSAvoidclub tangle

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The base is divided into two portions that can move relative to each other. The first portion remains ground-flush for stability, while the second portion moves to accommodate fabric and prevent bunching, resolving the contradiction between ground-flush stability and tangle prevention.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The movable second base portion acts as an intermediary mechanism between the ground-flush first base portion and the fabric. It mediates the conflict by moving to create space, preventing fabric bunching while maintaining the ground-flush contact of the first portion for stability.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Productivity

If multiple golf clubs are placed together in a single golf bag, then storage efficiency is improved, but the clubs can tangle and become difficult to remove

Engineering Contradiction:

Improvestorage efficiencyVSAvoidclub removal

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The base is segmented into movable portions that create expanding space. This segmentation allows multiple clubs to be stored efficiently while the movable base portions prevent fabric bunching that would cause club tangling, enabling easy club removal.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The movable second base portion is configured to proactively move away from the first base portion in response to leg extension, preemptively creating space before fabric bunching can occur. This preliminary action prevents club tangling before it happens, maintaining ease of club removal.

Inventive Principle:

Principle #10Preliminary action

AI summary

Described herein is a golf bag with a deployable stand assembly and anti-tangle features that prevent clubs from tangling within the golf bag, and in particular, prevent golf club grips from crossing over and other and making it difficult to pull out a particular club. When clubs are tangled, it becomes hard to remove a single golf club without either facing resistance or pulling a second club out. During a golf round, fabric portions of the bag can crumple, especially near the base, restricting the available area for the golf clubs. The area restriction can shift the grips and aggravate entanglement. The golf bag described herein comprises features that alleviate club tangle by preserving grip and shaft positions during bag use.
