Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple engines are installed to meet high power and torque requirements, then the power and torque of the vehicle are improved, but the available space in the vehicle is reduced
Solution Approach 1:
The patent merges the ignition control functions for multiple engines into a single igniter unit. This igniter is capable of simultaneously controlling multiple ignition coils across different engines, thereby reducing the total number of igniters needed and freeing up vehicle space while maintaining the required power and torque output from multiple engines
2Reliability
If each engine is equipped with dedicated ignition components, then the reliability of ignition control is improved, but the number of components and production costs increase
Solution Approach 1:
The patent implements a universal igniter design that can control multiple ignition coils across multiple engines. This multi-functional igniter reduces the overall number of ignition control units needed in the system, simplifying the device complexity and reducing production costs while maintaining reliable ignition control through centralized management of all ignition events
