Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel supply systems for vehicles with multiple large-capacity fuel tanks, such as large trucks and buses, face inefficiencies and safety risks due to incomplete communication filling protocols, leading to prolonged filling times and potential hazards.
Innovation Solution
A fuel supply apparatus with two supply systems, each equipped with a control device that determines communication filling status and adjusts fuel supply modes based on vehicle data, ensuring safe and efficient hydrogen delivery to multiple tanks by utilizing data from communicating or non-communicating systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single filling nozzle is used to fill multiple large-capacity fuel tanks, then the filling system complexity is reduced, but the filling time becomes very long
Solution Approach 1:
The filling system is segmented into multiple independent filling systems (first and second filling systems), each with its own filling nozzle, control device, and supply pipe. This allows parallel filling of multiple fuel tanks, significantly reducing total filling time while maintaining manageable complexity through modular design.
Solution Approach 2:
Multiple filling systems are combined to work simultaneously on the same vehicle, with each system connected to different fuel tanks. The control devices coordinate to manage the combined system, achieving rapid filling of all tanks through parallel operation.
2Productivity
If communication filling is attempted in all supply systems, then filling efficiency is maximized, but safety risks increase when communication is not established
Solution Approach 1:
The control mode of each filling system is made dynamic, automatically switching between communication filling and non-communication filling based on whether communication with the vehicle is established. This ensures optimal efficiency when communication is available while maintaining safety through conservative non-communication mode when it is not.
Solution Approach 2:
The control devices receive feedback from communication attempts with the vehicle and adjust their operation accordingly. When communication filling is established, the system operates in high-efficiency mode using vehicle data; when not established, it switches to safe non-communication mode, with the ability to switch modes based on real-time communication status.
3Reliability
If non-communication filling is used as a safe alternative, then filling safety is maintained, but filling time increases due to lack of real-time vehicle data
Solution Approach 1:
Each filling system is designed to perform multiple functions: communication filling when vehicle data is available, and non-communication filling when it is not. This multi-functionality allows the system to adapt to different situations, maintaining safety while minimizing time loss by using the appropriate mode for each specific case.
