Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a hydrogen storage container is stored in a fixed location, then hydrogen can be supplied to fuel cells, but the system lacks mobility and cannot provide various services at different locations

Engineering Contradiction:
Improveservice provision capabilityVSAvoidmobile unit weight
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The mobile unit is divided into functional modules: frame structure, movement mechanism with wheels, hydrogen storage tank insert parts, and fuel cell assembly. This segmentation allows the system to be mobile while maintaining all necessary functions for hydrogen storage and supply services at various locations.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple services are integrated into a single mobile unit, then various hydrogen-related services can be provided, but the device complexity increases

Engineering Contradiction:
Improveservice varietyVSAvoidmobile unit structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mobile unit is designed as a multi-functional platform that can perform hydrogen storage, hydrogen supply to fuel cells, lending of hydrogen storage tanks, and returning of used tanks. The frame structure with multiple insert parts and fuel cell integration enables a single device to handle various hydrogen-related services, reducing the need for multiple separate systems.

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

3Ease of operation

If hydrogen storage tanks are made available for lending and returning, then service flexibility improves, but management and tracking complexity increases

Engineering Contradiction:
Improvetank lending convenienceVSAvoidmanagement system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The mobile unit incorporates an electronic control device that automatically manages hydrogen storage tank operations. The system can autonomously control the insertion and removal of tanks into the insert parts, track tank status, and manage lending/returning processes, reducing manual intervention while maintaining service flexibility.

Inventive Principle:
Principle #25Self-service
