Sliding Door Locking Alignment via Position Sensor Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding door systems with toothed belt traction mechanisms face challenges in secure locking due to misalignment of form-fitting elements, requiring labor-intensive adjustments to ensure effective engagement of locking means with the traction means.
Innovation Solution
A method involving a locking device with a position sensor and motorized traction means that automatically adjusts the locking mechanism by moving the traction means relative to the locking means to achieve proper alignment, allowing for automatic detection and correction of locking positions without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking device with positive engagement is used to lock the door drive, then secure locking is achieved, but manual adjustment is required to align locking elements with the deflection pulley
Solution Approach 1:
The system automatically detects the position of the deflection pulley using a sensor and autonomously adjusts the locking device to align the locking elements with the pulley teeth, eliminating the need for manual adjustment while maintaining secure positive engagement locking
Solution Approach 2:
A sensor detects the position of the deflection pulley and provides feedback to the control unit, which then actuates the locking device accordingly to achieve automatic alignment and engagement, replacing manual adjustment procedures
2Reliability
If the locking device is adjusted to ensure proper engagement with the deflection pulley, then reliable locking is achieved, but installation time increases
Solution Approach 1:
The locking device performs self-alignment by automatically detecting the deflection pulley position and adjusting its own locking elements to engage with the pulley teeth, eliminating time-consuming manual adjustment during installation
Solution Approach 2:
The system pre-configures the locking device with automatic detection and adjustment capabilities, so that during installation the device automatically finds its correct position and engages with the pulley without requiring preliminary manual alignment
3Reliability
If the locking element is designed to engage with the toothed belt, then secure locking is achieved, but misalignment prevents effective engagement
Solution Approach 1:
The sensor detects the actual position of the toothed belt and deflection pulley, providing feedback to the control unit which then actuates the locking device to achieve precise alignment between locking elements and belt teeth, compensating for manufacturing tolerances
Solution Approach 2:
The system dynamically adjusts the position of the locking device based on detected parameters of the toothed belt and pulley positions, optimizing the alignment between locking elements and belt teeth to ensure effective engagement
