Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the internal combustion engine is frequently turned on and off in micro HEV, then fuel consumption is reduced during deceleration or braking, but voltage instability occurs more frequently during engine start
Solution Approach 1:
The voltage boost unit is activated in advance when a voltage-drop signal is detected from the vehicle computer unit, before the actual voltage drop occurs. This preliminary action ensures that the load unit receives stable voltage during engine start without interrupting the fuel-saving on-off operation of the internal combustion engine
Solution Approach 2:
The voltage boost unit acts as an intermediary between the vehicle battery unit and the load unit. When voltage instability is detected, the boost unit intervenes by providing boosted voltage to the load unit, isolating the load from the battery's voltage fluctuations during engine start
2Productivity
If the engine starts (ignites), then the vehicle can operate, but the battery voltage experiences an abrupt drop causing load interruptions
Solution Approach 1:
The microcontroller unit detects the voltage-drop signal from the vehicle computer unit in advance of the actual voltage drop, and activates the voltage boost unit before the engine start causes battery voltage to plummet. This timing ensures continuous stable power to the load unit
Solution Approach 2:
The voltage boost unit changes the voltage parameter by providing boosted voltage to the load unit when the battery voltage drops during engine start. This parameter change compensates for the battery's voltage decline and maintains stable operation of the load unit
