Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional suitcases with front pockets either lack access to the front compartment or reduce the main storage compartment's volume when an opening is provided, leading to potential damage of stored articles and inefficient use of space.

Innovation Solution

A suitcase design featuring a first and second body part that are movable relative to each other, a cover that pivots between open and closed positions, and a divider that adjusts to vary the size of the interior spaces, allowing for a larger front pocket and adaptable storage configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the front pocket is made deeper to increase storage volume, then the storage capacity is improved, but the front pocket becomes vulnerable to impact damage

Engineering Contradiction:

Improvefront pocket storage volumeVSAvoidimpact damage risk

Core Design Contradiction:

Volume of moving objectVSObject-affected harmful factors

Solution Approach 1:

The suitcase is divided into a main compartment and a front pocket compartment separated by a divider. The front pocket is further segmented into an upper portion (accessible when main compartment is open) and a lower portion (accessible when main compartment is closed), allowing independent access and protection strategies for each section.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The front pocket is designed with sufficient depth and structural support to cushion articles against impact damage before the impact reaches critical levels. The divider and pocket structure create a protective buffer zone that absorbs accidental impacts.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Ease of operation

If an opening is provided in the front pocket for access, then accessibility is improved, but the main storage compartment volume is significantly reduced

Engineering Contradiction:

Improvefront pocket accessibilityVSAvoidmain storage compartment volume

Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

Instead of creating a horizontal opening that would reduce main compartment width, the design provides vertical access through the front pocket's upper portion. The front pocket is positioned in the vertical dimension above the divider, allowing access without compromising the horizontal storage space of the main compartment.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The front pocket is segmented into an upper portion accessible when the main compartment is open and a lower portion accessible when closed. This segmentation allows independent access to front pocket items without requiring opening the main compartment, eliminating the need for large openings that would reduce main storage volume.

Inventive Principle:

Principle #1Segmentation

3Object-affected harmful factors

If the front pocket is made shallower to protect articles from damage, then impact protection is improved, but storage capacity is reduced

Engineering Contradiction:

Improveimpact protectionVSAvoidfront pocket storage capacity

Core Design Contradiction:

Object-affected harmful factorsVSVolume of moving object

Solution Approach 1:

The front pocket is designed with optimal depth that provides sufficient cushioning for article protection while maximizing storage capacity. The structure includes supportive elements that distribute impact forces, allowing the pocket to be deeper without proportionally increasing vulnerability to damage.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

4Stability of the object's composition

If the divider is made fixed to maintain stable compartment sizes, then structural stability is improved, but storage space adaptability is reduced

Engineering Contradiction:

Improvecompartment structural stabilityVSAvoidstorage space adaptability

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The divider is designed with movable engagement features that allow it to be repositioned along the inner peripheral surface of the first body part. The divider can be adjusted to different positions and secured at each position, providing both stability when fixed and adaptability when repositioned. The loop-shaped member with contact surfaces enables discrete positioning while maintaining structural integrity.

Inventive Principle:

Principle #15Dynamics
