Solution Overview

Problem

Luggage cases are inflexible in terms of size, requiring multiple cases of different sizes for varying travel needs, leading to inconvenience for frequent travelers.

Innovation Solution

An adaptable luggage case design featuring detachably connected lateral section structures that can be disassembled and reassembled into various reduced size configurations, allowing for adjustable dimensions by removing specific components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single luggage case is designed with fixed size, then manufacturing and storage are simplified, but the traveler must own multiple cases of different sizes to meet varying travel needs

Engineering Contradiction:
Improvesize adaptabilityVSAvoidcase structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The luggage case is divided into multiple detachable lateral section structures (first, second, third, fourth, and fifth lateral section structures) that can be selectively assembled or disassembled. Each lateral section structure contains detachably connected components that can be configured in different arrangements, enabling the case to be transformed between full-size and reduced-size configurations while simplifying manufacturing of individual modular components.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple luggage cases of different sizes are owned, then different travel needs are met, but the number of cases to maintain and transport increases

Engineering Contradiction:
Improvetravel configuration optionsVSAvoidnumber of luggage cases
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

A single luggage case is designed to perform multiple functions by accommodating different travel needs through reconfigurable lateral section structures. The case can be assembled in full-size configuration for extended trips requiring more space, or disassembled into reduced-size configurations for shorter trips, eliminating the need to maintain multiple separate luggage cases while providing diverse travel configuration options.

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

3Adaptability or versatility

If lateral section structures are detachably connected to enable size reduction, then versatility increases, but assembly and disassembly time increases

Engineering Contradiction:
Improvesize reconfigurabilityVSAvoidassembly time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The lateral section structures are pre-configured with standardized detachable connection mechanisms and complementary engagement features that enable quick assembly and disassembly. The connection structures are designed beforehand to align and engage rapidly, minimizing the time required to transform between full-size and reduced-size configurations while maintaining secure connections.

Inventive Principle:
Principle #10Preliminary action

AI summary

An adaptable luggage case includes a complete plurality of detachably connected components, including a first reduction group of components and a first reduced plurality of components that includes a second reduction group of components and second reduced plurality of components; such that the first reduced plurality of components assembles into a first reduced size luggage case, which is smaller than the adaptable luggage case; such that the second reduced plurality of components assembles into a second reduced size luggage case, which is smaller than the first reduced size luggage case.
