Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If delivery routes are optimized based only on efficient circuit routes, then delivery efficiency is improved, but fuel efficiency of hybrid vehicle is not maximized
Solution Approach 1:
The patent changes the optimization parameters from purely delivery efficiency metrics to a composite metric that includes fuel consumption characteristics. The route determination unit calculates fuel consumption for each candidate route by considering the hybrid vehicle's specific characteristics (electric motor and internal combustion engine usage patterns), and selects routes that optimize the balance between delivery efficiency and fuel efficiency.
2Use of energy by moving object
If electric motor is used for all traveling, then fuel efficiency is improved, but delivery productivity decreases due to limited range and power
Solution Approach 1:
The patent implements dynamic power source selection that adapts to real-time conditions. The vehicle control unit determines the optimal combination of electric motor and internal combustion engine usage based on route characteristics, vehicle state, and delivery requirements. This allows the system to flexibly switch between power sources to maintain both fuel efficiency and delivery productivity.
Solution Approach 2:
The hybrid vehicle system integrates multiple power sources (electric motor and internal combustion engine) into a unified propulsion system. The control unit can utilize either power source or both simultaneously depending on the situation, making the vehicle capable of operating efficiently across diverse delivery scenarios ranging from short urban routes to longer inter-city deliveries.
3Productivity
If internal combustion engine is used for all traveling, then delivery productivity is maintained, but fuel efficiency deteriorates
Solution Approach 1:
The patent modifies the operational parameters of the internal combustion engine by integrating it with an electric motor system. The control unit adjusts engine operating points to maintain high efficiency zones while using the electric motor to handle peak power demands and low-speed operations, thereby improving overall fuel efficiency without compromising delivery productivity.
4Device complexity
If route determination considers only map information and past delivery records, then delivery planning is simplified, but fuel efficiency optimization is insufficient
Solution Approach 1:
The patent implements a feedback mechanism where the vehicle control unit receives actual fuel consumption data and vehicle state information during deliveries, and uses this feedback to refine future route selections. The system accumulates data on actual fuel consumption patterns and uses this information to continuously improve route optimization accuracy.
Solution Approach 2:
The route determination unit performs preliminary calculations of fuel consumption for multiple candidate routes before the actual delivery begins. By pre-evaluating routes based on the hybrid vehicle's characteristics and expected operating conditions, the system can select the optimal route in advance without adding complexity to real-time decision-making during delivery operations.
