Solution Overview

Problem

Conventional luggage solutions lack an efficient way to transport additional luggage items while maintaining compact storage, as they do not have a collapsible and extendable mechanism to form a cart within the suitcase.

Innovation Solution

A suitcase with a rolling telescopic platform that is collapsible and storable within the exterior surfaces, forming a cart to transport additional luggage items, featuring a semi-rigid shell, casters, a stowing berth for storage, and adjustable telescopic beams for length adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a suitcase is designed to transport additional luggage items, then the transportation capability is improved, but the device complexity and storage space requirements worsen

Engineering Contradiction:

Improvetransportation capabilityVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rolling telescopic platform is nested within the suitcase body when collapsed, with the platform structure fitting inside the suitcase's exterior surfaces. The casters are stored within the platform frame, and the entire assembly retracts into the suitcase without protruding, allowing the suitcase to maintain its compact form while gaining extended transportation capability when needed

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The suitcase is designed to perform multiple functions: it serves as a standard carry-on luggage item for personal belongings, and simultaneously functions as a cart capable of transporting additional luggage items when the rolling telescopic platform is extended. This multi-functionality eliminates the need for separate cart equipment

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a rolling platform is extended to form a cart, then the transportation capability is improved, but the compact storage capability worsens

Engineering Contradiction:

Improvecart formation capabilityVSAvoidstorage compactness

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The rolling telescopic platform features movable telescopic beams that can extend and retract. When transportation of additional luggage is needed, the beams extend outward to form the cart structure. When not in use, the beams retract completely into the suitcase, allowing the platform to collapse to minimal dimensions and store within the suitcase's exterior surfaces without increasing its storage volume

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If adjustable telescopic beams are added for length adjustment, then the adaptability is improved, but the manufacturing complexity worsens

Engineering Contradiction:

Improvelength adjustabilityVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The telescopic beams are divided into multiple segments that can slide relative to each other. Each segment contains internal tracks or grooves that guide the movement of adjacent segments. This segmentation allows for adjustable length while using standardized modular components that simplify manufacturing and assembly processes

Inventive Principle:

Principle #1Segmentation
