Sliding Door Control System with Dynamic Movement and Edge Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door systems, particularly sliding door systems, often experience inappropriate opening or closing movements due to delayed or premature responses from sensor units, leading to inefficiencies and potential collisions with people or objects.
Innovation Solution
A control system with dual control modules, where a first module dynamically controls door movement based on person position, movement, and contour, and a second module ensures closing edge protection by independently evaluating sensor data to prevent collisions, using a redundant sensor setup with overlapping detection areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple sensor unit is used to detect person presence, then the device complexity is reduced, but the door movement response becomes inappropriate (too early or too late)
Solution Approach 1:
The control system is divided into multiple independent control modules (first control module for movement control, second control module for safety protection) that each process sensor data separately and can operate autonomously. This segmentation allows each module to optimize its response timing without interfering with the other, resolving the contradiction between simple sensor design and precise response timing.
Solution Approach 2:
The system continuously monitors sensor data and adjusts door movement parameters in real-time based on feedback from the sensor unit. The control modules receive continuous updates on person position, movement, and contour, allowing dynamic adjustment of door operation timing to match actual user needs, eliminating premature or delayed responses.
2Device complexity
If a single sensor unit is used for person detection, then the device complexity is reduced, but the safety protection function cannot react sufficiently quickly
Solution Approach 1:
The control system is divided into multiple independent control modules (first control module for movement control, second control module for safety protection) that each process sensor data separately and can operate autonomously. This segmentation allows each module to optimize its response timing without interfering with the other, resolving the contradiction between simple sensor design and precise response timing.
Solution Approach 2:
The second control module is specifically designed to evaluate sensor data in advance before door movement occurs, identifying potential collision risks beforehand. This preliminary safety assessment allows the system to prevent collisions before they happen, ensuring rapid response for closing edge protection without requiring additional sensor units.
3Productivity
If the door system responds quickly to sensor detection, then productivity is improved, but the risk of collision with people or objects increases
Solution Approach 1:
The system continuously monitors sensor data and adjusts door movement parameters in real-time based on feedback from the sensor unit. The control modules receive continuous updates on person position, movement, and contour, allowing dynamic adjustment of door operation timing to match actual user needs, eliminating premature or delayed responses.
Solution Approach 2:
The second control module is specifically designed to evaluate sensor data in advance before door movement occurs, identifying potential collision risks beforehand. This preliminary safety assessment allows the system to prevent collisions before they happen, ensuring rapid response for closing edge protection without requiring additional sensor units.
