Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the internal combustion engine is adjusted to provide a fixed rated output for reliable operation under worst-case conditions, then the reliability of the charging system is improved, but the adaptability to varying environmental conditions and demands deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of the internal combustion engine's output by establishing a maximum output that exceeds the rated output. The engine controller receives environmental condition information (temperature, humidity, altitude) and dynamically adjusts the engine output between the rated output and the maximum output based on current conditions. This allows the system to adapt to varying environmental conditions while maintaining reliable operation, resolving the contradiction between fixed reliability and environmental adaptability.
2Productivity
If the generator controller demands higher output from the internal combustion engine to meet charging defaults, then the productivity of the charging system is improved, but the reliability of the engine operation deteriorates due to exceeding rated output
Solution Approach 1:
The system dynamically adjusts the engine's maximum output based on environmental conditions. When conditions are favorable (lower temperature, lower altitude), the engine controller permits higher output up to the maximum, enabling faster charging. When conditions are unfavorable (higher temperature, higher altitude), the controller reduces the maximum output to maintain reliable engine operation. This dynamic adjustment resolves the contradiction between charging productivity and engine reliability.
Solution Approach 2:
The patent changes the operating parameters of the internal combustion engine by establishing a variable maximum output that exceeds the fixed rated output. The engine controller modifies engine parameters (fuel injection, air intake) based on environmental conditions to achieve optimal performance. This parameter adjustment allows the engine to operate reliably across different conditions while maintaining high charging productivity when possible.
3Productivity
If the charging system operates at maximum output under unfavorable environmental conditions, then the productivity is improved, but the harmful effects on the engine increase
Solution Approach 1:
The system takes preliminary anti-action by having the engine controller receive environmental condition information before the engine operates at high output. Based on this advance information about temperature, humidity, and altitude, the controller pre-adjusts the maximum output limits to prevent excessive engine stress and overheating. This preventive approach allows the system to maintain high productivity when conditions permit while protecting the engine from harmful effects when conditions are unfavorable.

Function Achieved in This Case
This solution allows for dynamic adjustment of charging output, voltage, and current, enhancing the flexibility and efficiency of the charging system, enabling faster charging under favorable conditions and maintaining reliability under unfavorable conditions by varying the internal combustion engine's maximum output based on environmental parameters.
Implementation Method 1
An electric generator is mechanically connected with the output shaft of the internal combustion engine. The generator serves to convert the mechanical energy that is generated by the internal combustion engine and that is transferred to the generator, into electrical energy.
