Dual-Strap Vertical Golf Bag for Spinal Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional golf bags distribute weight solely on one shoulder, leading to soft tissue injury, spinal misalignment, and unbalanced movement due to improper weight distribution, making them cumbersome and inefficient for extended use.
Innovation Solution
A vertically carried golf bag design with two shoulder straps mounted equidistantly and a chest strap to secure the bag, distributing weight evenly across both shoulders, and a lifting strap for ease of handling, allowing the bag to be carried upright with the opening behind the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional golf bag is carried on one shoulder, then the bag can be easily accessed and the structure is simple, but the weight distribution becomes unbalanced causing soft tissue injury and spinal misalignment
Solution Approach 1:
The carrying system is segmented into multiple independent straps (first shoulder strap, second shoulder strap, chest strap, and hip strap) that work together to distribute weight. Each strap serves a specific function in the overall weight distribution system, transforming the single-point load into a multi-point distributed load across the user's body.
Solution Approach 2:
The dual shoulder straps positioned equidistantly from the longitudinal axis create a balanced counterweight system. The straps are arranged to provide equal and opposite support forces, counteracting the unbalanced torque that would otherwise cause spinal misalignment and soft tissue injury from single-shoulder carrying.
2Device complexity
If the golf bag weight is concentrated on one shoulder, then the strap structure is simple, but the user experiences unbalanced movement and the bag shifts during walking
Solution Approach 1:
Multiple straps are merged into an integrated carrying system where the first shoulder strap, second shoulder strap, chest strap, and hip strap work together as a unified weight distribution system. This combination provides both structural stability and movement balance, preventing bag shifting during walking while maintaining manageable complexity through systematic integration.
Solution Approach 2:
The straps are positioned asymmetrically relative to the bag's longitudinal axis, with the first shoulder strap attached at a first distance and the second shoulder strap attached at a second distance from the axis. This asymmetric positioning creates balanced force distribution that stabilizes the bag during dynamic movement while allowing the opening to face forward or to the side for ease of access.
3Ease of operation
If the golf bag is carried with the opening facing forward or to the side, then the clubs are easily accessible, but the weight creates a cumbersome load that slows the user down
Solution Approach 1:
The dual shoulder straps positioned equidistantly from the longitudinal axis create an equipotential weight distribution system that balances the center of gravity. This balanced configuration reduces the effective load felt by the user during walking, maintaining walking speed while allowing the bag opening to face forward or to the side for easy club accessibility.
