Pivoting Golf Bag Strap Hinge for Easy Retrieval and Compact Stowage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf bags with carry straps, particularly Sunday bags, require frequent bending to retrieve the strap from ground level due to lack of legs, and existing strap elevations lead to tangling or increased storage space.
Innovation Solution
A pivoting hinge assembly that allows the carry strap to be deployed for easy retrieval and stowed for compact storage, with a detachable design that includes a slidable second end and a handle for ergonomic handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the carry strap is positioned near ground level for compact storage, then storage space is reduced, but the user must frequently bend over to reach for the strap
Solution Approach 1:
The carry strap is designed to be movable between two positions: a raised deployed position for easy access and a lowered stowed position for compact storage. The dynamic adjustment mechanism allows the strap to transition between these states, resolving the contradiction between accessibility and storage compactness.
Solution Approach 2:
The carry strap is positioned in a third dimension (vertically adjustable) rather than being fixed at ground level. This dimensional change allows the strap to be raised above ground level when deployed, improving accessibility without permanently increasing storage volume, as it can be lowered when not in use.
2Ease of operation
If the carry strap is raised higher above the ground, then ease of retrieval is improved, but the strap becomes harder to manage and occupies greater storage space
Solution Approach 1:
The carry strap transitions from a fixed raised position to a dynamically adjustable position. When not in use, it can be lowered to minimize storage space occupation, while during use it can be raised for easy retrieval. This dynamic capability resolves the contradiction between accessibility and storage efficiency.
3Ease of operation
If the carry strap is raised higher above the ground, then ease of retrieval is improved, but the strap may become tangled and occupy greater storage space
Solution Approach 1:
The movable design allows the carry strap to be positioned optimally - raised when needed for access, and lowered or secured when not in use to prevent tangling. This dynamic positioning eliminates the harmful effect of tangling while maintaining ease of retrieval when required.

AI summary
A pivoting hinge assembly for a golf bag has a rotable arm connected to a boss on the diver, and a cam mechanism that moves between a deployed and a stowed state. A carry strap has opposite ends attached to the rotable arm and the flat. When the cam engages the first detent, the carry strap is placed in a deployed state in which it protrudes away from the bag to facilitate grasping when the bag is placed on the ground. When the cam engages the second detent, the carry strap is placed in a stowed state wherein the carry strap nests with the bag, creating a compact footprint that facilitates stowing.
