Solution Overview

Problem

Existing tote bags are often not durable, water-resistant, and difficult to clean, and lack structural integrity to remain upright when loaded, making them inconvenient for carrying bulky or large items.

Innovation Solution

A tote bag design featuring a semi-rigid base, water-resistant and antimicrobial materials, easy-clean construction, and internal compartments with waterproof zippers, along with reinforced straps and MOLLE loops for versatility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional tote bags are made from flexible materials for portability, then ease of carrying is improved, but structural integrity and ability to remain upright deteriorates

Engineering Contradiction:

Improveease of carryingVSAvoidstructural integrity

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The base of the tote bag is segmented into a semi-rigid structure that is attached to the bottom of the flexible bag body. This segmentation allows the bag to maintain flexibility for carrying while the segmented base provides structural support and upright stability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The semi-rigid base is applied locally to the bottom portion of the tote bag, providing structural integrity where needed for stability, while the rest of the bag remains made of flexible materials for ease of carrying and portability.

Inventive Principle:

Principle #3Local quality

2Ease of operation

If traditional tote bags are made from non-waterproof materials for comfort, then ease of operation is improved, but resistance to water and ease of cleaning deteriorates

Engineering Contradiction:

Improveease of operationVSAvoidwater resistance

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The material properties of the tote bag are changed to be water-resistant while maintaining flexibility. The semi-rigid base and water-resistant coating or material selection modify the physical parameters of the bag to resist water penetration while preserving ease of operation.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If traditional tote bags lack structural support for carrying bulky items, then adaptability is improved, but stability and durability deteriorates

Engineering Contradiction:

ImproveadaptabilityVSAvoidstability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The semi-rigid base is pre-attached to the tote bag during manufacturing, providing structural support before the bag is used to carry bulky items. This preliminary structural preparation ensures stability and durability from the outset while maintaining adaptability for various carrying needs.

Inventive Principle:

Principle #10Preliminary action

AI summary

A collapsible divider for a bag may include an internal divider panel attached to an interior wall of a bag and may be configured to transition from a first position to a second position in which the first position is a stowed configuration and the second position is an extended configuration. The internal divider panel may include a pull tab positioned at an upper portion of the internal divider panel, the internal divider panel may include an internal divider panel reinforcement layer along a top border of the internal divider panel, and an internal material may be positioned around an upper portion of the interior wall of the bag in which the internal divider panel reinforcement layer is seated beneath a lower portion of the internal material when the internal divider panel is in the first position.
