Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If electrical energy is transmitted from power-generating device to power-requiring devices through vehicle battery storage, then energy can be stored and supplied flexibly, but transmission loss and storage loss increase
Solution Approach 1:
The vehicle is divided into multiple sections, each with its own power source control box. Power-generating devices in each section are directly connected to power-requiring devices in the same section through local control boxes, segmenting the energy transmission path and reducing overall transmission loss and storage loss.
Solution Approach 2:
Power source control boxes serve as intermediary devices that manage power distribution locally within each section. These control boxes enable direct power transmission from power-generating devices to power-requiring devices without requiring centralized battery storage, thereby reducing transmission and storage losses.
2Productivity
If power source control boxes are provided to each section and connection wires are used for direct power transmission, then energy efficiency improves, but wiring complexity increases
Solution Approach 1:
The wiring structure is segmented into multiple independent sections, each with its own power source control box and connection wires. This segmentation allows for localized power management and simplifies the overall wiring architecture by distributing control functions across multiple sections rather than requiring a complex centralized wiring system.
Solution Approach 2:
Power source control boxes are designed as universal components that can be installed in each section of the vehicle. Each control box performs multiple functions including power reception from power-generating devices, power distribution to power-requiring devices, and local control operations, thereby simplifying the overall wiring structure through component standardization.
3Loss of energy
If electrical energy is stored in vehicle battery before supply, then power supply stability is improved, but charging loss increases
Solution Approach 1:
The invention extracts the power storage function from the centralized vehicle battery system and implements local power management in each section. By taking out the intermediate battery storage step and enabling direct power transmission from power-generating devices to power-requiring devices, charging loss is eliminated while power supply stability is maintained through local control.
Solution Approach 2:
The system enables continuous direct power transmission from power-generating devices to power-requiring devices without interruption for battery charging cycles. This continuous action eliminates the energy losses associated with charging and discharging cycles while maintaining reliable power supply through real-time local control.
