Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional generators are installed in fire service vehicles to ensure power supply, then power availability is improved, but emissions and device complexity increase
Solution Approach 1:
The patent combines multiple voltage sources (batteries, alternators, external power supply) into a single integrated voltage supply system with centralized control. The control apparatus manages the combined operation of these diverse power sources, optimizing their coordination to reduce emissions while ensuring reliable power supply for all vehicle consumers.
Solution Approach 2:
The voltage supply system is designed to universally accept and manage multiple types of power sources including onboard batteries, alternators connected to travel motors, and external power supply units. This multi-functional system can adaptively select and combine different power sources based on operational requirements, eliminating the need for additional dedicated generators.
2Reliability
If multiple voltage sources operate independently without coordination, then power availability is improved, but energy efficiency deteriorates due to inefficient operation
Solution Approach 1:
The control apparatus continuously monitors the operational status, emission values, and power output of each voltage source. Based on this feedback, the control system dynamically adjusts the operation of individual power sources, optimizing their combined performance to minimize energy waste while maintaining sufficient power supply for all consumers.
Solution Approach 2:
The system dynamically adjusts the operational state of each voltage source based on real-time conditions. The control apparatus can connect or disconnect power sources, adjust their output levels, and optimize their coordination according to current power demands and emission considerations, rather than operating in fixed independent modes.
3Power
If all voltage sources are operated simultaneously to meet high power demand, then power availability is improved, but emissions increase
Solution Approach 1:
The control apparatus changes the operational parameters of each voltage source based on emission values and power requirements. By adjusting which power sources are active and at what output levels, the system optimizes the balance between total power output and total emissions, selecting the most emission-efficient combination of power sources for each operational scenario.

AI summary
A voltage supply and drive system for a fire service vehicle or rescue vehicle or special utility vehicle has at least one drive source and having a plurality of voltage sources which are connected to one another by an electrical power system, and a control device. At least one of the voltage sources is formed by a battery, characterized in that the control device is designed to connect or disconnect one or more voltage sources and/or one or more drive sources taking into account at least one emission value of at least one of the voltage sources and/or at least one of the drive sources. As a result, the voltage and/or drive sources which are integrated into the voltage supply and drive system of the fire service vehicle and rescue vehicle or special utility vehicle can be operated, combined in such a way that an overall minimal emission value can be achieved.
