Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steering lock devices for vehicles require multiple detection units to determine the position of the actuating element, which increases complexity and cost, and lack efficient methods for noise minimization during operation.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple detection units are used to determine the position of the actuating element, then the reliability of position detection is improved, but the device complexity and cost increase
Solution Approach 1:
The patent combines multiple detection functions into a single detection unit by using a circumferential detection area that can detect the actuating element at multiple positions during its rotation. This merging approach maintains position detection reliability while reducing the number of separate detection units required
Solution Approach 2:
The single detection unit is designed with a circumferential detection area that performs multiple detection functions - it can detect whether the actuating element is in a first end position, second end position, or intermediate position by detecting the presence or absence of the actuating element at different angular positions during rotation
2Device complexity
If a single detection unit is used to reduce complexity and cost, then the device complexity is reduced, but the ability to accurately determine actuating element position may be compromised
Solution Approach 1:
The detection system uses the dynamic rotation of the moving element to enable a single stationary detection unit to detect the actuating element at multiple positions throughout its rotation cycle. The detection unit evaluates signals at different times during rotation to determine the current position, transforming a static single-point detection into a dynamic multi-point detection system
Solution Approach 2:
The evaluation unit uses feedback from the detection unit's signals, combined with knowledge of the moving element's rotation state, to accurately determine the actuating element's position. The system monitors whether the actuating element is detected during rotation and uses this feedback information to infer the current position state

AI summary
The invention relates to a steering locking device (1) for a vehicle, comprising at least one electric motor, a movement element (2) and an adjusting element (3), wherein the electric motor and the adjusting element (3) are in mechanical operative connection with one another indirectly via the movement element (2), in such a way that the adjusting element (3) can move between a first end position (P1) releasing the steering of the vehicle and a second end position (P3) blocking the steering of the vehicle. According to the invention, a detection unit (4) is provided which can detect whether the adjusting element (3) is in one of the end positions (P1, P3), wherein the detection unit (4) can be switched between two states and a position of the adjusting element (3) depends on the state in which the detection unit (4) is switched, and wherein the detection unit (4) has a detection range and the detection unit (4) can be transferred into another state by means of a movement of the movement element (2) through the detection range.
