Solution Overview

Problem

Conventional dual carrying strap golf bags and similar shoulder-borne articles are difficult to place over both shoulders due to the fixed connection of straps, leading to discomfort and tripping hazards when carrying with one strap, and lack ease in single strap use.

Innovation Solution

A dual strap system where the second strap is pivotally movable with respect to the first strap, allowing for easier placement and removal over the shoulder, using a pivot snap buckle mechanism for adjustable and secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the straps are fixedly connected to provide stable dual strap carrying, then the load distribution is improved, but the ease of placement and removal is worsened

Engineering Contradiction:
Improvestrap connection stabilityVSAvoidease of placement and removal
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent applies a movable connection mechanism between the two shoulder straps, allowing the straps to dynamically adjust their relative positions. The second strap can move freely along the first strap within a defined range, enabling easy placement and removal while maintaining stable load distribution when worn.

Inventive Principle:
Principle #15Dynamics

2Stress or pressure

If dual straps are used to distribute load evenly, then spine stress is reduced, but the complexity of the carrying system is increased

Engineering Contradiction:
Improvespine stressVSAvoidcarrying system complexity
Core Design Contradiction:
Stress or pressureVSDevice complexity

Solution Approach 1:

The patent divides the strap system into two independent yet connected components. Each strap can be adjusted and positioned independently, with the second strap moving relative to the first strap. This segmentation allows for simplified adjustment mechanisms while achieving even load distribution across both shoulders.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If the second strap is fixedly attached to the first strap, then the structural simplicity is maintained, but the adaptability for single strap use is reduced

Engineering Contradiction:
Improvestructural simplicityVSAvoidsingle strap use capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The movable connection between the straps enables the system to adapt between different carrying configurations. The second strap can be positioned alongside the first for dual strap carrying, or moved to allow single strap use, providing versatility while maintaining relatively simple structure.

Inventive Principle:
Principle #15Dynamics

AI summary

Dual-strap carrying assemblies and devices including such assemblies are provided herein. The carrying devices may be embodied in dual carrying strap golf bags that allow the bearer to more easily don and remove the bag. The secondary strap of the dual strap assembly is connected to the primary strap by a movable engagement assembly, such as an assembly that rotates to allow the secondary strap to more easily become within the reach of the bearer of the bag. In some embodiments, the movable engagement assembly may include a movement limiting device that prevents the secondary strap from moving too far out of the bearer's reach. The strap assemblies may be used in combination with a flexible base stand to make a self-standing carrying device that is easy to don and doff.
