Solution Overview

Problem

Existing golf bag strap systems are either single-strap or double-strap configurations, which are not adaptable for convenient single-strap use on either side of the body, leading to uneven weight distribution and user fatigue, especially for caddies carrying two bags.

Innovation Solution

A convertible strap system for golf bags that can be easily converted between single-strap and double-strap configurations using a back puck mechanism, allowing the second strap to be removably engaged or disengaged to accommodate different carrying needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If a double-strap system is used, then weight distribution is improved, but device complexity increases

Engineering Contradiction:
Improveweight distributionVSAvoidstrap system complexity
Core Design Contradiction:
ForceVSDevice complexity

Solution Approach 1:

The strap system is divided into independent first and second straps that can be used separately or together. Each strap can be independently attached to the bag, allowing the user to segment the loading process and choose which strap to use based on the situation, thereby reducing the perceived complexity while maintaining the option for even weight distribution when both are used

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The strap system transitions from a static fixed configuration to a dynamic reconfigurable system. The straps can be attached, detached, and repositioned based on the user's needs. This dynamic capability allows the same strap system to adapt between single-strap and double-strap modes, improving weight distribution when needed without permanently increasing complexity

Inventive Principle:
Principle #15Dynamics

2Device complexity

If a single strap system is used, then device complexity is reduced, but weight distribution deteriorates

Engineering Contradiction:
Improvestrap system complexityVSAvoidweight distribution
Core Design Contradiction:
Device complexityVSForce

Solution Approach 1:

The strap system is designed to perform multiple functions through a single integrated structure. The same first and second straps can be used individually for single-strap carrying or together for double-strap carrying. This multi-functionality allows the simplified single-strap configuration to provide adequate weight distribution for short distances while maintaining the capability for even weight distribution when both straps are engaged

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Force

If a double-strap system with crisscrossing straps is used, then weight distribution is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveweight distributionVSAvoidsingle strap carrying convenience
Core Design Contradiction:
ForceVSEase of operation

Solution Approach 1:

The crisscrossing strap configuration is segmented into independent first and second straps that can be used separately. When single-strap carrying is needed, the user can detach one strap from the crisscrossing configuration, eliminating the obstruction in the elbow area while maintaining the option for even weight distribution when both straps are used together

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The problematic crisscrossing intersection is extracted or removed from the active configuration when single-strap carrying is needed. By making the straps detachable from the crisscrossing arrangement, the design removes the harmful element (elbow obstruction) while preserving the beneficial double-strap configuration when both straps are engaged

Inventive Principle:
Principle #2Taking out (Extraction)

4Force

If a fixed double-strap configuration is used, then weight distribution is improved, but adaptability deteriorates

Engineering Contradiction:
Improveweight distributionVSAvoidcarrying configuration adaptability
Core Design Contradiction:
ForceVSAdaptability or versatility

Solution Approach 1:

The fixed double-strap configuration is transformed into a dynamic reconfigurable system. The straps can be attached to and detached from the crisscrossing arrangement, allowing the user to adapt the configuration based on the situation. This dynamic capability provides versatility for both single-strap and double-strap carrying modes while maintaining the option for even weight distribution when both straps are engaged

Inventive Principle:
Principle #15Dynamics

AI summary

Embodiments of a strap assembly system for a golf bag are described herein. The strap assembly system can be converted between a single-strap configuration or a double-strap configuration. The strap assembly system comprises a first strap, a second strap, and a back puck. The back puck comprises first and second attachment openings for securing the first strap. The back puck further comprises first and second side openings that define a linear pathway and are configured to receive the second strap. The second strap can move freely along the linear pathway.
