Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hydrogen-storing container and hydrogen fuel stack are added to achieve high range endurance and zero emission, then the energy management system becomes more complex, but the failure rate increases and user experience deteriorates
Solution Approach 1:
The energy management system is divided into multiple independent control modules: a first control module manages the hydrogen fuel cell system (controlling hydrogen flow, air supply, and electrical output), while a second control module manages the lithium battery pack (controlling charging and discharging). This segmentation allows each module to operate independently with specialized control logic, reducing the failure rate by isolating potential issues to specific modules rather than a monolithic complex system.
Solution Approach 2:
The system incorporates multiple sensors (temperature sensors, humidity sensors, pressure sensors) that continuously monitor the state of the hydrogen fuel cell and lithium battery, feeding this information back to the respective control modules. The control modules adjust their operation based on this feedback, enabling dynamic optimization and early detection of abnormal conditions, thereby improving reliability without requiring excessive system complexity.
2Reliability
If a simple management system is used to reduce device complexity, then manufacturing costs decrease, but the failure rate increases and user experience worsens
Solution Approach 1:
The control system is segmented into standardized modular units that can be manufactured independently and assembled during final integration. The first control module for the hydrogen fuel cell system and the second control module for the lithium battery pack are designed as separate manufacturable entities with standardized interfaces, reducing overall manufacturing complexity while enabling sophisticated control functions that improve reliability.
Solution Approach 2:
The control modules are designed with multi-functional capabilities that reduce the need for specialized components. For example, the control modules can manage both normal operation and abnormal condition response, and can control multiple subsystems (hydrogen flow, air supply, electrical output) using unified control architecture, thereby simplifying manufacturing processes while maintaining high reliability through comprehensive control functions.
