Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If hybrid vehicles use combination of fossil fuel engine and electric motor to generate propulsion, then efficiency gains are achieved through proper monitor and control of electrical power, but the complexity of vehicle electrical control systems is exacerbated
Solution Approach 1:
The patent implements self-service by enabling devices to autonomously monitor and control their own electrical power consumption and generation. Each device independently manages its electrical quantities without requiring complex centralized control, thereby reducing overall system complexity while maintaining efficient power utilization in hybrid vehicles.
2Reliability
If priorities are assigned to subsystems to keep highest priority systems operational during power shortages, then reliability of critical systems is improved, but the complexity of power management control increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting electrical limit values based on power availability and system priorities. The control module modifies electrical quantity parameters (such as current or power limits) for different devices according to real-time conditions, enabling reliable operation of critical systems during power shortages without requiring complex manual intervention or rigid control structures.
3Ease of operation
If electrical limit values are transferred to devices for self-regulation, then ease of operation is improved through automated control, but the complexity of communication protocols and interfaces increases
Solution Approach 1:
The patent implements universality by creating a standardized communication interface that can handle multiple functions: transferring electrical limit values, monitoring device status, and coordinating power management across different device types. This multi-functional communication protocol reduces the need for device-specific control mechanisms, thereby simplifying overall system operation despite the added communication capabilities.
