Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If hybrid vehicles are developed by coupling thermal motor and electric motor, then fuel consumption and emissions are reduced, but market penetration remains insufficient and energy endurance is limited
Solution Approach 1:
The system enables the vehicle to automatically manage its own energy resources by intelligently coordinating the thermal engine and electric motor based on real-time operating conditions, optimizing fuel consumption and emissions reduction without requiring complex user intervention or system modifications
Solution Approach 2:
The hybrid powertrain system performs multiple functions: it can operate in pure electric mode for urban driving, switch to thermal engine mode for highway driving, and combine both modes for optimal efficiency, making the vehicle adaptable to various driving conditions and increasing its market appeal
2Use of energy by moving object
If photovoltaic panels are integrated into the vehicle, then solar energy is utilized for energy accumulation, but the power available is much lower than the maximum power of the motorcar
Solution Approach 1:
The photovoltaic panels continuously accumulate solar energy during the day and store it in the battery, preparing energy reserves in advance for periods when the vehicle needs additional power or when solar energy is not available, such as during nighttime or cloudy periods
Solution Approach 2:
The system merges the photovoltaic energy generation system with the existing hybrid powertrain, combining solar energy, battery energy, and thermal engine power into a unified energy management system that optimizes the contribution of each source based on real-time demands
3Adaptability or versatility
If a kit for transforming conventional vehicles is developed, then existing vehicles can be converted into hybrid vehicles, but the original motor control system would need to be modified
Solution Approach 1:
The system introduces an intermediary control unit that communicates with the existing motor control system through standardized interfaces, translating between the legacy system and the new hybrid control requirements without requiring modification of the original control architecture
Solution Approach 2:
The control system is segmented into independent modules: the original motor control system remains unchanged, while a new hybrid control unit manages the electric motor and energy management, with clear separation of functions and communication through standardized protocols
4Measurement precision
If sensors are added to detect driving conditions, then precise control of motorized wheels is achieved, but the system complexity and cost increase
Solution Approach 1:
The system utilizes feedback from existing vehicle sensors and controllers through the OBD interface to infer driving conditions, eliminating the need for additional sensors by cleverly processing available data to determine acceleration, braking, and driving mode with sufficient precision for hybrid control
