Solution Overview

Problem

Current luggage designs face challenges in achieving a balance between lightweight durability and resistance to wear and damage, particularly during loading, unloading, and movement, as they often compromise on either weight or durability.

Innovation Solution

The introduction of interchangeable luggage perimeters featuring a modular base element that can securely and releasably couple with exchangeable components such as foot pads, wheels, and handles, allowing for repositioning at multiple edges of the luggage piece, thereby enhancing versatility and durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional rigid frame construction is used, then durability is improved, but weight increases

Engineering Contradiction:
ImprovedurabilityVSAvoidweight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The luggage frame is divided into modular components including a modular frame structure with interchangeable perimeters and exchangeable components (wheels, handles, foot pads). This segmentation allows for optimized weight distribution and selective replacement of worn parts without replacing the entire frame, resolving the contradiction between durability and weight.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs composite construction combining rigid frame elements with flexible exchangeable components. The modular frame integrates different materials and structures (rigid perimeter frames with flexible exchangeable parts) to achieve optimal strength-to-weight ratio, where the rigid frame provides structural integrity while lighter exchangeable components reduce overall weight.

Inventive Principle:
Principle #40Composite materials

2Adaptability or versatility

If exchangeable components are added, then adaptability is improved, but device complexity increases

Engineering Contradiction:
ImproveversatilityVSAvoidcomplexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The interchangeable base element serves multiple functions: it provides structural support, enables attachment of various exchangeable components (wheels, handles, foot pads), and allows repositioning at different edges. This multi-functionality increases versatility without proportionally increasing complexity, as a single base element design supports multiple applications.

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

Solution Approach 2:

The system incorporates dynamic reconfigurability through the interchangeable base element that can be repositioned at multiple edges and combined with various exchangeable components. This dynamic adaptability allows the luggage to be customized for different needs while maintaining a relatively simple base design, managing the complexity-versatility trade-off.

Inventive Principle:
Principle #15Dynamics

AI summary

Interchangeable luggage perimeters are disclosed. Example interchangeable luggage perimeters may comprise an interchangeable base element adapted to securely and releasably couple with exchangeable components such as exchangeable foot pads, exchangeable wheels, or exchangeable handles. The interchangeable base element may be interchangeable by having a configuration supporting repositioning of the interchangeable base element at multiple different edges of a luggage piece, e.g., any of at least two or four edges of a luggage piece.
