Solution Overview

Problem

Existing shopping bags lack efficient organization and handling features for differentiating and transporting various types of products, particularly in self-service retail environments, and there is a need for a solution that allows easy access to larger compartments without disturbing smaller items inside.

Innovation Solution

A multiple bag design comprising a first bag with a first compartment and two handles, and a second bag with a second compartment and two handles, where the second bag is housed inside the first bag and attached by one handle, allowing easy access to the larger bag while keeping smaller items secure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate bags are used to organize different products, then organization capability is improved, but the number of handles increases making handling more difficult

Engineering Contradiction:
Improveorganization capabilityVSAvoidhandling difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent combines multiple separate bags into a single integrated multiple bag structure where a first bag and second bag are connected through shared handles. The first handle serves as both a handle for the first bag and as a connecting element to the second bag, reducing the total number of handles from four to three while maintaining separate compartments for organizing different products.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The first handle performs multiple functions: it serves as a carrying handle for the first bag, as a connecting element to attach the second bag, and as a structural link between the two bags. This multi-functionality reduces the overall number of handles needed while maintaining organization capabilities.

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

2Volume of moving object

If a small bag is placed inside a large bag, then space utilization is improved, but access to the large bag requires removing the small bag first

Engineering Contradiction:
Improvespace utilizationVSAvoidaccess difficulty
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The multiple bag is divided into two independent but connected segments: a first bag and a second bag. Each bag maintains its own opening and can be accessed independently. The second bag is attached to the first bag through the first handle, allowing the first bag to be opened and accessed without removing the second bag, as they are separate compartments rather than nested containers.

Inventive Principle:
Principle #1Segmentation

3Ease of manufacture

If all handles are made identical, then manufacturing is simplified, but users cannot quickly identify which handles are free for carrying

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoididentification time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The patent introduces asymmetry by making the first handle different from the second and third handles. The first handle includes a fastening element and serves as a connecting element, while the second and third handles are simple carrying handles. This differentiation allows users to quickly identify which handles are free for carrying versus which handle is used for connection, without significantly complicating the manufacturing process.

Inventive Principle:
Principle #4Asymmetry

AI summary

The invention relates to a multiple bag consisting of a first bag and a second, smaller bag located inside the first bag and attached to it by one of the handles, whereby the multiple bag has only three handles. The multiple bag comprises a first bag (1) with a first compartment (3) and two first handles (4) and a second bag (2) with a second compartment (6) and two second handles (7), wherein the second bag (2) is housed inside the first bag (1), and the two bags (1, 2) are fastened by one of the handles (4, 7), turning the multiple bag into a bag with three handles.
