Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If hydrogen storage devices are exchanged manually at external filling stations, then refueling can be performed, but the infrastructure is insufficient and user convenience is reduced

Engineering Contradiction:
Improverefueling convenienceVSAvoidinfrastructure requirement
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system enables self-service refueling by automatically generating hydrogen on-site through electrolysis and autonomously exchanging storage devices. The control unit coordinates the generating device, filling device, and loading/unloading device to perform refueling operations without human intervention, eliminating dependence on external filling stations

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent introduces an intermediate storage device that temporarily holds generated hydrogen before transferring it to the vehicle's mounting device. This intermediary component decouples the hydrogen generation process from the vehicle refueling process, enabling automated operation and reducing the need for direct connection to external infrastructure

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If hydrogen is generated on-site via electrolysis, then independence from external infrastructure is achieved, but the device complexity increases

Engineering Contradiction:
Improveindependence from infrastructureVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system is divided into functionally independent modules: a generating device for hydrogen production, a filling device for storage device refilling, and a loading/unloading device for automatic exchange. Each module operates semi-independently under control of a control unit, allowing the system to achieve infrastructure independence while managing complexity through modular architecture

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary hydrogen generation and storage before vehicle refueling is needed. The generating device can produce and store hydrogen in advance in the intermediate storage device, so that when refueling is required, the process can be executed quickly and automatically without needing external infrastructure at the moment of use

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If automatic loading and unloading device is implemented, then user manual work is eliminated, but the device complexity and cost increase

Engineering Contradiction:
Improveautomation levelVSAvoidmechanical system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical operations with an automated loading and unloading device that uses mechanical arms or conveyors to remove emptied storage devices from the vehicle and install filled ones. This substitution eliminates the need for users to manually handle heavy storage devices, achieving high automation while the complexity is managed through integrated control systems

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
