Solution Overview

Problem

Existing bags fail to adequately protect personal items and professional equipment from physical impacts and external environments during travel, and do not facilitate easy and stable transport of multiple bags simultaneously.

Innovation Solution

The bags are designed with protective covers, wheels or rollers, handle assemblies, and connector systems that allow for linking multiple bags together, forming a self-stabilizing assembly for easy transport and protection from damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If bags are designed with protective covers and connector systems to protect contents and enable linking, then protection reliability and transport stability are improved, but device complexity increases

Engineering Contradiction:
Improveprotection reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The bag system is divided into modular components including protective covers, connector assemblies, handle assemblies, and wheel assemblies that can be independently designed, manufactured, and attached. This segmentation allows each component to be optimized for its specific function while maintaining overall system reliability without excessive complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connector assembly serves multiple functions: it links bags together in series, provides structural support for the protective cover, and integrates with the handle assembly for unified transport. This multi-functionality improves protection reliability while minimizing the addition of separate components.

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

2Ease of operation

If multiple bags are linked together to form a self-stabilizing assembly for easy transport, then transport stability and ease of operation are improved, but device complexity increases

Engineering Contradiction:
Improvetransport easeVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Multiple bags are merged into a single self-stabilizing assembly through the connector system that links them in series. The combined assembly functions as one unified transport unit with a single handle, improving ease of operation by allowing one person to transport multiple bags simultaneously without complex coordination.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The linked bag assembly is designed to be self-stabilizing, meaning the configuration of multiple bags connected in series automatically provides structural stability and balance during transport without requiring active intervention or adjustment by the user. The system serves itself by maintaining stability through its own geometry and connector design.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If bags are designed with retractable handle assemblies and protective covers, then ease of operation and protection are improved, but manufacturing complexity increases

Engineering Contradiction:
Improvehandle operation easeVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The handle assembly is designed to retract into the protective cover when not in use, with the handle, support members, and housing nested within the cover structure. This nesting approach provides the functionality of a retractable handle while minimizing the number of separate manufacturing processes by integrating components into existing structural elements.

Inventive Principle:
Principle #7Nested doll (Nesting)
