Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door systems lack automated mechanisms for detecting collisions and intrusions, leading to potential damage and operational disruptions, which can cause safety issues and hinder access to buildings.
Innovation Solution
A system comprising movement sensors and processing circuitry that analyze door movements using a movement-to-event model to determine probable events causing the movement, enabling proactive control and maintenance actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual inspection is used to detect door damage, then the system is simple and easy to operate, but the detection is delayed and downtime is increased
Solution Approach 1:
The movement sensor continuously monitors door movements in advance to detect collisions or intrusion attempts before they cause significant damage or operational failure. By performing preliminary detection, the system can alert operators or trigger protective actions before the door becomes non-functional, thus reducing downtime and maintaining reliability.
Solution Approach 2:
The system implements continuous feedback by monitoring door movements and comparing them against normal operation patterns. When abnormal movements are detected (indicating collision or intrusion), the system provides immediate feedback through alerts or notifications, enabling rapid response and minimizing operational disruption.
2Measurement precision
If no automated detection system is installed, then the system complexity is low, but collision and intrusion detection is delayed
Solution Approach 1:
The patent replaces manual inspection (mechanical human labor) with an automated sensor-based system. The movement sensor electronically detects door movements and the processing circuitry automatically analyzes the data to identify collisions or intrusions, providing precise detection without requiring physical inspection of the door.
Solution Approach 2:
The system performs self-monitoring and self-diagnosis by automatically detecting abnormal movements and identifying potential issues without requiring external inspection. The processing circuitry autonomously analyzes sensor data and determines whether a collision or intrusion has occurred, reducing the need for manual intervention.
3Reliability
If the door is manually inspected frequently, then detection reliability is improved, but operational efficiency and productivity decrease
Solution Approach 1:
The movement sensor operates continuously to monitor door movements without interruption, providing constant surveillance of the door's operational status. This continuous monitoring ensures that any collision or intrusion is detected immediately, maintaining high detection reliability while not interfering with normal door operations or access efficiency.
Solution Approach 2:
The automated electronic monitoring system replaces manual inspection processes, enabling simultaneous continuous monitoring and uninterrupted door operation. Unlike manual inspection which requires stopping or observing the door, the sensor system monitors movements electronically without affecting door functionality or access productivity.
