Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromechanical wheel brakes are designed for specific applications and adapting them to new operating requirements often requires substantial and expensive re-design, making it difficult to achieve functional testing only in the installed state.
Innovation Solution
The wheel brake is composed of modular components, including an electromotive drive assembly, transmission assembly, and clamping device, which can be checked for function independently and connected via standardized interfaces, allowing for flexible adaptation to different requirements without extensive re-design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wheel brake is designed as a specific application scenario with fixed dimensions and components, then the braking power meets the established specifications, but the adaptation to new operating requirements requires substantial and expensive new construction
Solution Approach 1:
The wheel brake is divided into independent functional modules: an electromechanical drive unit, a transmission unit with gear stages, and a clamping device. Each module can be independently selected, tested, and replaced to adapt to different application requirements without redesigning the entire brake system.
Solution Approach 2:
The standardized interfaces between modules enable a universal design where the same basic modular components can serve multiple different application scenarios. By changing only the transmission ratio or clamping device geometry while keeping other modules unchanged, the system adapts to various braking power requirements.
2Reliability
If the wheel brake components are designed as integrated fixed units, then the functional testing can only be performed in the installed state, but the adaptation to different requirements becomes complex and costly
Solution Approach 1:
Each functional module (drive unit, transmission unit, clamping device) is designed as a separate testable component that can be independently verified before assembly. This segmentation allows functional testing at the module level rather than requiring complete system installation for testing.
Solution Approach 2:
The functional modules are pre-tested and pre-configured independently before final assembly. This preliminary action ensures that each module meets functional requirements separately, simplifying the overall system integration and reducing the complexity of post-assembly adjustments.
3Power
If the electromechanical drive, transmission assembly, and clamping device are designed as fixed integrated units, then the wheel brake meets specific braking power specifications, but the response speed and torque cannot be easily adjusted
Solution Approach 1:
The transmission unit incorporates selectable gear stages with different transmission ratios, allowing the system to dynamically adjust the relationship between motor speed and clamping force. This enables optimization of both response speed and torque output depending on the specific application requirements.
Solution Approach 2:
By changing the transmission ratio through different gear stage selections or modifying the clamping device geometry, the system can adjust key performance parameters such as response speed and torque without replacing the entire brake assembly. The electromechanical drive unit can also be exchanged for models with different power characteristics.

AI summary
An electromechanical wheel brake for a motor vehicle, has an electromotive drive assembly designed to impinge a drive shaft with a torque. A transmission assembly transmits a torque acting on the drive shaft to an output shaft. A clamping device converts a torque acting on the output shaft into a clamping force acting along a clamping direction. A clamping force sensor system determines the clamping force generated by the clamping device. A control unit controls the drive assembly on the basis of a brake request and an applied clamping force. The drive assembly, the transmission assembly and the clamping device are each functional modules which can be checked for their respective function and, in the installed state, enter into operative connection via correspondingly designed interfaces. In the installed state of the wheel brake the interfaces establish a signal connection between the control unit and the clamping force sensor system.
