Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The actuation of blocking slides in vehicle brakes, especially in electrically operated systems, is not always optimal, leading to potential issues with engagement and release, particularly when engaging with structured surfaces.
Innovation Solution
A method using an electromagnet to actively move a structured surface into a specified orientation, allowing the blocking slide to engage easily and prevent rotation in a controlled manner, combined with an actuating unit and vehicle brake system that includes an angular position sensor for precise positioning and calibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the blocking slide is actuated without active orientation control, then the actuation process is simple, but engagement reliability deteriorates due to improper positioning on projections
Solution Approach 1:
The structured surface is actively moved into a specified orientation before the blocking slide is actuated. This preliminary positioning ensures that the blocking slide engages properly with the structured surface, avoiding improper engagement on projections and thereby improving engagement reliability without requiring complex additional components
2Manufacturing precision
If the blocking slide engages without controlled orientation, then the actuation mechanism remains simple, but actuation precision deteriorates leading to improper engagement
Solution Approach 1:
An angular position sensor detects the actual angular position of the structured surface and provides feedback to the control device. The control device uses this feedback to determine when the specified orientation has been achieved, ensuring precise engagement of the blocking slide with the structured surface
3Measurement precision
If no orientation monitoring is implemented, then the system structure remains simple, but positioning accuracy deteriorates causing engagement issues
Solution Approach 1:
The angular position sensor continuously monitors the angular position of the structured surface and communicates this information to the control device. This feedback mechanism enables precise measurement and control of the orientation, ensuring that the blocking slide engages at the correct position

AI summary
The invention relates to a method for actuating a blocking slide which is actuatable by means of an electromagnet and which, in at least one position, engages into a structured surface, whereby the blocking slide prevents a rotation of the structured surface in at least one direction of rotation, wherein, before a deployment of the blocking slide, the structured surface is moved into a specified orientation. The invention furthermore relates to an actuating unit for carrying out such a method, and to a vehicle brake having such an actuating unit.
