Convertible Bag Strap System for Backpack and Messenger Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag designs that convert between single-strap over-the-shoulder and dual-strap backpack configurations require additional straps or components, and often necessitate disconnecting and reconnecting straps, making the transition inefficient.
Innovation Solution
A combination bag with a strap system that is fixedly attached to the bag body at one connection point and slideably coupled at another, allowing for easy switching between configurations without additional components or disconnection, using a strap with connectors and securing mechanisms like hoops or loops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a bag uses a single-strap over-the-shoulder configuration, then it is stylish and fashionable, but the weight load is not evenly distributed causing back pain
Solution Approach 1:
The bag strap system is designed to be dynamically reconfigurable, allowing the user to switch between a single-strap over-the-shoulder configuration for style and a dual-strap backpack configuration for balanced weight distribution. The straps can be easily adjusted and repositioned to transform the bag's carrying configuration based on the user's needs.
2Adaptability or versatility
If a bag converts between single-strap and dual-strap configurations using additional straps or components, then it provides versatility, but the conversion process becomes complicated and time-consuming
Solution Approach 1:
The bag's existing strap system is designed to serve multiple functions: it can be configured as a single over-the-shoulder strap for fashionable carry, or reconfigured as two backpack straps for balanced carrying. The same strap components perform both roles without requiring additional specialized parts, simplifying the conversion process.
Solution Approach 2:
The invention merges the functions of multiple strap configurations into a single integrated strap system. The same strap structure and components are used for both the single-strap and dual-strap configurations, eliminating the need for separate straps or additional conversion components.
3Adaptability or versatility
If a bag requires disconnecting and reconnecting straps to convert configurations, then it provides adaptability, but it slows down the transition and complicates operation
Solution Approach 1:
The strap system is pre-configured with attachment points and connection mechanisms that enable quick reconfiguration. The straps are designed with predetermined connection points on the bag body, allowing the user to rapidly switch between configurations by simply moving the straps to different pre-positioned attachment points rather than disconnecting and reconnecting components.

AI summary
The present invention relates to bags, including backpacks and messenger bags. Specifically, the present invention relates to methods and apparatus for converting a bag between backpack and over-the-shoulder configurations. A combination bag may comprise a bag body having a front panel, a back panel, a bottom panel, and an opening opposite the bottom and a strap, wherein the strap is fixedly attached to the bag body at a first connection point and slideably coupled to the bag body at a second connection point, thereby enabling a wearer to alternate between an over-the-shoulder and a backpack configuration without requiring that the wearer disconnect or reconnect the strap.
