Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Entrance systems with automatic door operators face challenges in ensuring compliance with safety standards due to improper installation or mounting, leading to potential accidents and component wear, as the torque transfer characteristics of the linkage are non-linear and dependent on various factors, and human errors can result in non-compliance with mounting requirements.
Innovation Solution
A testing system for entrance systems that includes a controller configured to operate in a testing mode, utilizing a sensor unit with a door angle sensor to determine test parameters, such as door leaf angles, and evaluate the installation's compliance with safety standards by measuring and comparing against predefined thresholds, adjusting the system if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual settings or learn cycle methods are used to obtain control input data, then the controller can operate the automatic door operator, but the torque transfer characteristics of the linkage cannot be accurately determined due to their non-linear nature
Solution Approach 1:
The testing system performs preliminary measurements of the linkage's torque transfer characteristics during installation or maintenance. The controller executes a learn cycle that systematically varies the door position and measures the actual torque required, storing this data for future operational adjustments. This preliminary characterization enables accurate control without requiring complex real-time calculations during normal operation.
Solution Approach 2:
The system uses its own motor and controller to automatically perform the testing and measurement process. The controller drives the motor through various positions while sensors measure the actual torque and position, allowing the system to self-characterize its torque transfer properties without external testing equipment or manual intervention.
2Reliability
If the linkage mounting is not compliant with mounting requirements due to human errors, then the entrance system may fail to satisfy technical standard requirements and increase accident risk, but implementing comprehensive testing increases system complexity
Solution Approach 1:
The testing system incorporates sensors that provide real-time feedback on actual door position, torque requirements, and operational parameters during the testing phase. The controller compares measured values against expected ranges and provides feedback on compliance status. This automated feedback mechanism verifies mounting compliance and identifies deviations without requiring complex manual inspection procedures.
Solution Approach 2:
The system performs comprehensive safety and compliance testing during the installation or maintenance phase before normal operation begins. The controller executes a series of predetermined test sequences that verify mounting compliance, torque transfer characteristics, and safety requirements. Any deviations are identified and corrected before the system enters regular service, preventing safety issues from developing during operation.
3Ease of operation
If the controller needs various control input data including non-linear torque transfer characteristics, then accurate control can be achieved, but the complexity of obtaining and processing this data increases
Solution Approach 1:
The controller automatically performs the data collection process by executing a learn cycle that systematically varies motor output and measures actual door position and torque requirements using integrated sensors. The system self-generates the test sequences and automatically processes the measured data to create the torque transfer characteristic curves, eliminating the need for external testing equipment or manual data entry.
Solution Approach 2:
The system replaces complex manual measurement procedures with electronic sensing and automated data processing. Instead of requiring physical torque measurement devices and manual recording, the controller uses electronic sensors to measure position and current, then calculates torque transfer characteristics through software algorithms. This substitution of mechanical measurement systems with electronic ones simplifies the overall complexity while maintaining accuracy.
