Door System with Motion and Object Recognition Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door systems in secure areas face challenges in preventing unauthorized access from unsecured to secured areas, relying heavily on human security personnel which is manpower-intensive and prone to human error.
Innovation Solution
A door system equipped with a sensor system that includes motion sensors and object recognition sensors connected to a door controller, allowing for selective access and automatic locking mechanisms to prevent wrong-way movement, potentially replacing human security personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security personnel are stationed at exits to prevent unauthorized access, then security reliability is improved, but operational cost and complexity increase due to manpower requirements
Solution Approach 1:
The patent replaces human security personnel with an automated sensor-based system. Motion sensors detect movement in the corridor, object recognition sensors identify objects or persons, and the door controller automatically responds by locking the door. This mechanical/automated substitution eliminates the need for continuous human monitoring while maintaining or improving security reliability.
2Difficulty of detecting and measuring
If human security personnel are used to monitor exits, then detection capability is improved, but human error susceptibility increases
Solution Approach 1:
The system replaces human detection with automated sensors that have consistent, repeatable detection capabilities. Motion sensors provide reliable motion detection without fatigue or distraction, and object recognition sensors consistently identify objects or persons. This eliminates human error susceptibility while maintaining high detection capability.
3Productivity
If automated sensor systems are implemented, then operational efficiency is improved by reducing manpower needs, but system complexity increases
Solution Approach 1:
The system is divided into distinct functional modules: motion sensors for detecting movement, object recognition sensors for identifying objects or persons, and a door controller for executing security decisions. This segmentation allows each component to perform its specific function efficiently, improving operational efficiency while making the overall system more manageable despite increased automation.
