Magnetic Golf Bag Leg Retention for Droop-Free Stand Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf bags with retractable stands often experience leg drooping or inadvertent deployment during transport, requiring manual intervention for leg retention, which can be cumbersome and inefficient.
Innovation Solution
A retractable stand assembly with magnetic leg retention assemblies that utilize magnets to securely hold the legs in a retracted position without manual actuation, featuring a push rod mechanism and high-friction soles for stability, allowing hands-free operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual intervention is used to retain legs in retracted position, then leg retention can be achieved, but user convenience deteriorates and operation becomes cumbersome
Solution Approach 1:
The magnetic leg retention assembly automatically retains the leg in the retracted position without requiring manual intervention. The magnet embedded in the foot portion attracts to the metal plate on the leg, providing self-retaining functionality that eliminates the need for users to manually secure the leg.
Solution Approach 2:
The patent replaces manual mechanical retention (straps, clips, or manual positioning) with a magnetic retention system. The magnetic force between the magnet in the foot portion and the metal plate on the leg provides the retaining force, eliminating the need for complex mechanical retention mechanisms requiring manual operation.
2Ease of operation
If retractable stand assembly is used, then ease of carrying is improved, but leg stability deteriorates during transport
Solution Approach 1:
The magnetic retention assembly provides preliminary retention force to counteract the natural tendency of the leg to droop or deploy during transport. By continuously applying magnetic attraction force, the system prevents the leg from moving into an unstable position before the user needs to use the stand.
Solution Approach 2:
The magnetic field acts as an intermediary force between the foot portion and the leg. This magnetic intermediary provides a continuous retaining force that stabilizes the leg in the retracted position during transport, eliminating the need for manual intervention while maintaining stability.
3Reliability
If magnetic leg retention assembly is added, then leg retention reliability is improved, but device complexity increases
Solution Approach 1:
The magnetic retention system is segmented into two simple components: a magnet embedded in the foot portion and a metal plate attached to the leg. This segmentation allows each component to be simple and easy to manufacture, while their interaction provides effective retention functionality without requiring a complex integrated mechanism.
Solution Approach 2:
The patent extracts the retention function from complex mechanical systems and implements it through a simple magnetic interaction. By taking out the essential retention function and implementing it through magnetism rather than complex mechanical linkages, the system achieves reliable retention with minimal complexity.
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 magnetic leg retention system effectively prevents leg drooping and inadvertent deployment, ensuring the golf bag remains stable during transport and use, enhancing user convenience and reliability.
Implementation Method 1
A magnet may be embedded in the foot portion to retain the leg in a retracted position
Implementation Method 2
The sole may include a high-friction surface to prevent slipping when the leg is in the deployed position

AI summary
Examples of golf bags and methods to manufacture stand golf bags are generally described herein. A golf bag may include a body portion. A first leg and a second leg may be pivotally coupled to the body portion and moveable between a retracted position against the body portion and a deployed position away from the body portion. The first leg may couple with a first foot portion having a first leg retention portion configured to aid in retaining the first leg in the retracted position through magnetic attraction between the first leg retention portion and the body portion. The second leg may couple with a second foot portion having a second leg retention portion configured to aid in retaining the second leg in the retracted position through magnetic attraction between the second leg retention portion and the body portion. Other examples may be described and claimed.
