Undulating Strap Slots for Object Retention

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing systems for carrying multiple objects, such as purses and handbags, often cause objects to fall to the bottom, making them difficult to retrieve, and liquid-filled bottles risk leaking if not kept upright.

Innovation Solution

A system comprising flexible sheets with undulating straps and elastic material, coupled with fasteners and hook-and-loop fasteners, which creates slots for object retention and allows secure attachment to surfaces, ensuring objects remain upright and accessible.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If multiple objects are placed into a purse or handbag, then the capacity to carry multiple objects is improved, but the objects fall to the bottom making them difficult to retrieve

Engineering Contradiction:

Improvenumber of objects carriedVSAvoidease of retrieving objects

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The interior of the bag is segmented into multiple compartments using dividers that create separate slots or sections. Each compartment can hold specific objects, preventing them from falling to the bottom and making retrieval easier by knowing exactly where each item is located.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of allowing objects to堆叠 vertically to the bottom, the system uses horizontal dividers and multiple layers to distribute objects across different dimensional planes. This creates accessible zones at various heights and positions, eliminating the need to dig through accumulated objects at the bottom.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Quantity of substance

If bottles filled with liquid are placed in a bag, then the capacity to carry multiple objects is improved, but the bottles may leak if not kept upright

Engineering Contradiction:

Improvenumber of objects carriedVSAvoidprevention of liquid leakage

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

Specific compartments or slots are designed with upright orientations and specialized structures (such as vertical walls or cradles) that accommodate bottles in an upright position. This localized design ensures that liquid-containing objects maintain their proper orientation while other compartments can be configured differently for non-liquid items.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

Instead of relying on the bag's overall structure to keep bottles upright, the system inverts the approach by creating individual upright cradles or slots within the bag that actively support bottles in the correct orientation, regardless of how the bag itself is positioned.

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of operation

If objects are retained in an organized manner with dividers, then the ease of retrieving objects is improved, but the device complexity increases

Engineering Contradiction:

Improveease of retrieving objectsVSAvoidstructural complexity of holding system

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The dividers and organizational structures are made from flexible, thin materials that can be easily manufactured and integrated into the bag. These flexible partitions provide effective separation and organization while adding minimal weight and structural complexity compared to rigid dividing systems.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The divider system is designed to be multi-functional, serving both as organizational separators and as structural support elements for the bag. The same components that create compartments also provide reinforcement and shape maintenance, reducing the need for additional complex structural elements.

Inventive Principle:

Principle #6Universality (Multi-functionality)
