Parking Lock Module PCB Integration for Simpler Vehicle Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing parking lock modules for motor vehicles require complex and labor-intensive installation and cabling, especially in restricted spaces, due to separate components and cables for the solenoid and travel sensor, which increases the effort and difficulty in installation.
Innovation Solution
A parking lock module with an integrated circuit board that serves as both an electrical path for the electromagnetic actuator and a mechanical carrier for the sensor arrangement, allowing for simplified installation and pre-testing, and featuring a plug connector for easy connection, reducing the need for separate cabling and positioning of the sensor system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate components and cables are used for the solenoid and travel sensor, then the installation and cabling effort increases and becomes more complex, but the functional reliability is maintained
Solution Approach 1:
The circuit board integrates multiple functions: it serves as the electrical connection interface for the electromagnetic actuator (solenoid) and simultaneously as the mechanical mounting carrier for the position detector (travel sensor). This merging of functions reduces the number of separate components and eliminates the need for separate cabling, directly reducing installation effort and cabling complexity while maintaining all necessary functions
Solution Approach 2:
The circuit board performs multiple roles within the parking lock module: it acts as an electrical connector for the solenoid, a mechanical support structure for the position detector, and a signal processing unit. This multi-functionality consolidates what would otherwise require separate components and cabling systems, resolving the contradiction between ease of installation and device complexity

Function Achieved in This Case
This design significantly simplifies the installation and contacting of the parking lock module by integrating the sensor and actuator electronics, reducing the number of components and cabling required, and allowing for pre-testing before final installation, thus minimizing effort and improving reliability.
Implementation Method 1
detent element which interacts with the positioning member for this purpose, which detent element is movable at least by means of an electromagnetic actuator between an arresting position and a release position
Implementation Method 2
The electromagnetic actuator is activatable by means of a circuit board which is attached to the housing and which also bears the position detector of the sensor arrangement

AI summary
A parking lock module has a housing, in which, for the actuation of a parking lock, a positioning member is movable between a locking position and an unlocking position. The positioning member is selectively fixable in a position relative to the housing with an arresting device, which has a detent element interacting with the positioning member. The detent element is movable with an actuator between arresting and release positions. A sensor arrangement with a position detector, which is positionally fixed relative to the housing, and a position encoder, which, for the detection of the respective position, is operatively connected to the positioning member or to the detent element. The electromagnetic actuator is activatable with a circuit board attached to the housing and bears the position detector of the sensor arrangement.
