Solution Overview

Problem

Existing bag systems are difficult to manufacture, assemble, access stored items, couple efficiently, detach, and provide a secure mechanism for additional items, often requiring additional straps and being cumbersome.

Innovation Solution

A bag system featuring a connector with a buckle and latch assembly that securely couples a supplemental bag to a main bag through a slit in the main bag, requiring actuation of two buttons to detach, ensuring secure and efficient coupling and protection of items.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional coupling mechanisms (straps, zippers, hooks, snaps, belts, buckles) are used to secure bags together, then the bags can be coupled for transporting items, but the mechanism is difficult to manufacture, assemble, and detach

Engineering Contradiction:
Improvesecure couplingVSAvoidmanufacturing and assembly difficulty
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The coupling mechanism is divided into separate components: a connector with a tongue on the supplemental bag and a buckle with latch means on the main bag. This segmentation allows independent manufacturing and assembly of each component while maintaining secure coupling functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connector acts as an intermediary element between the supplemental bag and main bag. The connector with its tongue engages with the buckle's latch means, providing a secure coupling mechanism that is easier to manufacture and assemble than traditional integrated mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If additional straps are used to secure supplemental bags, then the coupling can be secure, but the system becomes cumbersome and difficult to operate

Engineering Contradiction:
Improvesecure couplingVSAvoiddifficulty to detach
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The latch assembly incorporates two buttons that, when actuated simultaneously, automatically release the latch means and disconnect the connector from the buckle. This self-service mechanism eliminates the need for manual manipulation of complex fastening systems while maintaining secure coupling during transport.

Inventive Principle:
Principle #25Self-service

3Volume of stationary object

If items are stored together in a single large compartment, then storage capacity is maximized, but it is difficult to access specific items and items may be lost

Engineering Contradiction:
Improvestorage capacityVSAvoidaccess to specific items
Core Design Contradiction:
Volume of stationary objectVSEase of operation

Solution Approach 1:

The bag system is divided into a main bag and a supplemental bag that can be coupled together. This segmentation allows items to be distributed across two separate compartments, maintaining overall storage capacity while enabling easier access to specific items by opening only the supplemental bag when needed.

Inventive Principle:
Principle #1Segmentation

4Adaptability or versatility

If multiple separate pieces are carried separately, then each bag can function independently, but the handling becomes less manageable

Engineering Contradiction:
Improveindependent functionalityVSAvoidhandling manageability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The coupling mechanism is designed to be dynamic rather than permanent. The supplemental bag can be coupled to the main bag when additional storage or manageable handling is needed, and easily detached when independence is required. The two-button release system enables quick transition between coupled and separate states.

Inventive Principle:
Principle #15Dynamics

AI summary

There is a bag system, comprising: a main bag, including a front side, wherein: a slit is disposed along the front side; and a buckle is coupled to an interior surface of the front side; and a supplemental bag, removably coupled to the main bag, and including a connector, wherein: the connector is disposed along a back side of the supplemental bag; and the connector is disposed through the slit and removably coupled to the buckle, the connector and the buckle thereby comprising a latch assembly.
