Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical interface arrangements between vehicles and operating implements, such as tractors and trailers, fail to effectively manage electrical energy transmission, leading to potential overload situations that can endanger operating safety, especially when high-load electrical consumers like electric motors are used.
Innovation Solution
An electrical interface arrangement with a measuring arrangement and actuator associated with the vehicle interface to quantify and vary electrical state variables, including current, voltage, and resistance, allowing for precise energy management and overload prevention by adjusting the internal combustion engine's rotational speed or vehicle speed.

Engineering Contradiction Analysis
1Productivity
If electrical consumers with large energy requirements are connected to the vehicle, then the operational capability of the operating implement is improved, but overload situations occur that endanger operating safety
Solution Approach 1:
The control arrangement proactively monitors electrical state variables (current, voltage, power) before overload conditions occur and preemptively adjusts the engine rotational speed or disconnects consumers to prevent dangerous overload situations, rather than reacting after the problem arises
Solution Approach 2:
The measuring arrangement continuously provides feedback on electrical state variables to the control arrangement, enabling real-time monitoring and dynamic adjustment of the electrical energy supply to maintain safety while supporting high-power operations
2Power
If the rotational speed of the internal combustion engine is increased to respond to high load on electrical consumers, then the electrical energy supply is improved, but the fuel consumption increases
Solution Approach 1:
The system dynamically adjusts the engine rotational speed based on real-time electrical load conditions, optimizing the balance between power supply requirements and fuel consumption by varying engine speed rather than maintaining constant high speed
Solution Approach 2:
The control arrangement changes operational parameters (engine rotational speed, electrical energy supply levels) in response to measured electrical state variables, optimizing the trade-off between power delivery and fuel efficiency under different operating conditions
