Vehicle Door Locking Mechanism with Eccentric Pin and Sensor Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking mechanisms for sliding doors in vehicles are prone to causing injuries due to complex and error-prone emergency interruptions, which can lead to jamming if sensor devices fail.
Innovation Solution
A locking mechanism with a start-stop control device that queries power consumption and stops the drive if a threshold is exceeded, combined with an optical or pressure-sensitive detection system to prevent door closure when obstacles are detected, and a locking pin designed as an eccentric for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensor devices are used for emergency interruption, then safety is improved, but reliability deteriorates due to sensor failure and jamming
Solution Approach 1:
The patent introduces a monitoring device as an intermediary between the sensor and the control system. This monitoring device independently verifies sensor signals and can detect sensor failures, preventing false emergency interruptions or failure to interrupt when needed. The monitoring device acts as a mediator that filters and validates sensor inputs before they trigger the emergency release mechanism.
Solution Approach 2:
The system implements feedback through the monitoring device that continuously checks sensor functionality and signal validity. When the sensor detects an obstacle, the monitoring device verifies this signal before triggering the emergency release. This feedback loop ensures that only valid obstacle detections trigger the release mechanism, preventing jamming from false signals while maintaining safety from true obstacles.
2Reliability
If complex emergency interruption mechanisms are used, then safety is improved, but device complexity increases
Solution Approach 1:
The monitoring device performs self-verification of sensor signals and can detect its own operational status. The system monitors itself for proper functioning, reducing the need for additional complex external monitoring systems. The control unit integrates the monitoring function, allowing the system to self-regulate and reduce overall complexity while maintaining safety.
Solution Approach 2:
The monitoring device is integrated with the control unit, combining multiple functions into a single control system. Rather than having separate independent monitoring and control systems, the patent merges them into one integrated control unit that handles both normal operation and emergency interruption logic, thereby reducing device complexity while maintaining safety functions.
3Ease of operation
If manual emergency release is provided, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The actuating element serves multiple functions: it can manually release the locking mechanism for emergency opening, and it can also be actuated by the automated emergency release mechanism when sensors detect obstacles. This multi-functional design allows the same component to handle both manual and automated emergency release, reducing the need for separate mechanisms and thereby reducing overall device complexity while maintaining ease of manual operation.
