Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional battery is used to start the diesel engine, then the engine can be started, but the battery requires frequent replacement and has limited cycle life
Solution Approach 1:
The patent combines a super-capacitor module and a battery module into a hybrid power module. The super-capacitor handles high-current starting demands while the battery provides sustained energy, allowing the battery to operate within optimal voltage ranges and extend its cycle life while maintaining reliable engine starting.
Solution Approach 2:
The hybrid power module dynamically allocates power between the super-capacitor and battery based on real-time demands. During engine starting, the super-capacitor provides the initial high current surge, then transitions to supporting the battery, optimizing the battery's operational parameters and extending its lifespan.
2Use of energy by moving object
If the truck alternator directly powers the refrigeration system, then power is available, but the system relies heavily on the alternator and truck engine
Solution Approach 1:
The hybrid power module extracts the energy storage function from the alternator-truck-engine system. It includes a super-capacitor module connected to the alternator and a battery module, creating an independent energy buffer that reduces direct reliance on the truck alternator and engine for refrigeration system power.
Solution Approach 2:
The super-capacitor module charges in advance during truck operation and provides immediate power during engine starting and refrigeration system operation, preparing energy beforehand to reduce dependency on the alternator and truck engine.
3Object-affected harmful factors
If environmental regulations limit engine idling, then emissions are reduced, but the refrigeration system cannot operate continuously when stationary
Solution Approach 1:
The hybrid power module accumulates energy in advance during truck operation when the engine is running. This stored energy in the super-capacitor and battery modules enables the refrigeration system to operate continuously during stationary periods without requiring the truck engine to idle, thus reducing emissions while maintaining refrigeration reliability.
Solution Approach 2:
The system converts the limitation of not being able to idle into an opportunity to use the hybrid power module's stored energy. The super-capacitor and battery store energy during operation, which is then utilized during stationary periods to maintain refrigeration without engine idling, turning a regulatory constraint into a benefit for both emissions reduction and system reliability.
4Reliability
If a hybrid power module with super-capacitor and battery is used, then battery life is extended and power availability is improved, but the device complexity increases
Solution Approach 1:
The power system is segmented into distinct functional modules: a super-capacitor module with first and second terminals, and a battery module with corresponding terminals. This segmentation allows each module to be optimized independently while working together, managing complexity through modular design.
Solution Approach 2:
The hybrid power module serves multiple functions: the super-capacitor provides high-current bursts for engine starting, the battery provides sustained energy for refrigeration systems, and together they extend battery cycle life and reduce alternator dependency. This multi-functionality justifies the increased complexity by delivering comprehensive power management solutions.
