Solution Overview
Problem
Existing electropneumatic two-circuit brake value transmitters require complex and power-intensive central modules that need to be individually programmed for each vehicle type, increasing complexity and power requirements.
Innovation Solution
An electropneumatic control valve with an application-specific electronic and/or electromechanical measuring unit housed in a partially closed electronics housing, which can be easily exchanged and connected to the control valve, allowing for universal use without adapting the central module, and autonomously generating signals for the braking system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal central module is used for different vehicle types, then the device complexity and power requirements increase, but the adaptability to different vehicle types decreases
Solution Approach 1:
The system is divided into a universal control valve and exchangeable application-specific measuring units. The measuring unit contains vehicle-specific parameters and is replaced rather than reprogrammed, separating the universal control logic from vehicle-specific adaptations.
Solution Approach 2:
Instead of reprogramming the central module for different vehicle types, the invention changes the physical measuring unit component. Each measuring unit is pre-configured with specific parameters for its vehicle type, allowing parameter changes through component replacement rather than software modification.
2Adaptability or versatility
If the central module is individually programmed for each vehicle type, then the adaptability to different vehicle types improves, but the ease of operation and adjustment decreases
Solution Approach 1:
The vehicle-specific programming is extracted from the central module and placed into separate measuring units. This allows the central module to remain universal and unchanged, while vehicle-specific adaptations are handled by simply replacing the measuring unit component.
Solution Approach 2:
The measuring unit is designed as a self-contained, pre-configured component that automatically provides the correct parameters for its specific vehicle type. The system serves itself by using the measuring unit's inherent configuration rather than requiring external programming or adjustment.
3Adaptability or versatility
If the central module is made more powerful to handle different vehicle types, then the adaptability improves, but the power requirements increase
Solution Approach 1:
The system segments the computational and parameter-storing functions into separate measuring units that are exchanged based on vehicle type. The central module only needs to execute standard control algorithms, reducing its power requirements while maintaining overall system adaptability through unit replacement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Simplifies the adjustment and reduces the power requirements of the electropneumatic control valve by allowing the measuring unit to be set up as an application-specific sub-unit, enabling direct signal generation for the braking system without modifying the central module, thus reducing complexity and power consumption.
