Solution Overview

Problem

Travelers face challenges with bulky luggage and the need for adaptable carrying capacity, as existing luggage systems do not efficiently adjust to changing requirements during trips, often resulting in unnecessary bulk or the need to carry multiple items.

Innovation Solution

A modular expandable luggage system with a removable item and an expandable section that can increase the volumetric space by 25% to 200% through a flexible material and support mechanisms, allowing for adjustable capacity by deploying an expandable side from a stored configuration to define a larger volumetric space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If travelers carry multiple items of luggage to meet changing needs, then carrying capacity is sufficient, but the number of items and overall bulk increases

Engineering Contradiction:

Improvecarrying capacityVSAvoidnumber of luggage items

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The luggage item incorporates an expandable section that can be deployed or retracted to change the internal volume dynamically. This allows a single luggage item to adapt its carrying capacity based on travel needs, eliminating the requirement to carry multiple separate items.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The expandable section is constructed with expandable walls that can be divided into multiple panels or segments. These segments can be independently adjusted to create different volume configurations, providing versatile carrying capacity while maintaining a compact form when collapsed.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If luggage volume is increased to meet carrying needs, then carrying capacity is sufficient, but the bulk and size of the luggage increases

Engineering Contradiction:

Improvecarrying capacityVSAvoidluggage volume

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The expandable section is nested within the main body of the luggage item when in its collapsed state. The expandable walls are stored inside the existing volumetric space, allowing the luggage to maintain a compact size during transport while providing expanded capacity when needed.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The expandable section uses expandable walls that can be deployed outward from the main body to increase volume dynamically. This allows the luggage to transition between compact and expanded states, providing large carrying capacity only when actually needed rather than always maintaining large size.

Inventive Principle:

Principle #15Dynamics

3Volume of stationary object

If an expandable section is added to increase volumetric space, then carrying capacity is improved, but the device complexity increases

Engineering Contradiction:

Improvevolumetric spaceVSAvoidluggage structure

Core Design Contradiction:

Volume of stationary objectVSDevice complexity

Solution Approach 1:

The expandable walls are constructed from flexible materials that can be easily folded, expanded, and stored. This flexibility simplifies the mechanical structure compared to rigid expandable components, reducing overall device complexity while still achieving significant volume increase.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The expandable section is divided into multiple expandable walls or panels that can be independently controlled. This segmentation allows for simpler individual components rather than one complex monolithic structure, making the overall system easier to manufacture and maintain.

Inventive Principle:

Principle #1Segmentation

AI summary

An item of luggage, comprising: a plurality of sides sufficient to define a first volumetric space, an expandable section disposed within the space between first and second opposing sides, wherein at least the first opposing side defines a boundary for the volumetric space and provides an exterior surface for the item of luggage; the expandable section having a first configuration wherein it is stored within the space and has an expandable side that is adjacent to the first opposing side, and a second configuration wherein the expandable side extends a predetermined distance from the first opposing side to define a boundary for a second volumetric space that is the same as or different from the first volumetric space.
