Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of sensors and detection modules is increased to improve detection accuracy, then detection precision is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple detection functions into a single integrated detection module. The detection module integrates optical sensors, infrared sensors, and other detection elements into one unified structure that can detect multiple parameters (presence, temperature, humidity) simultaneously, thereby improving detection accuracy without proportionally increasing device complexity
Solution Approach 2:
The detection module is designed with multi-functionality to perform various detection tasks using a single device. It can detect human presence, measure temperature, measure humidity, and trigger different responses based on the detected parameters, reducing the need for multiple separate sensors and modules
2Adaptability or versatility
If scenario detection modules are added to detect and respond to various scenarios, then adaptability is improved, but device complexity increases
Solution Approach 1:
The escalator system dynamically adjusts its operation based on detected scenarios. The control unit receives data from the detection module and automatically modifies escalator parameters (speed, direction, or shutdown) according to the detected scenario, enabling adaptive response without requiring complex mechanical modifications
Solution Approach 2:
The system implements a feedback mechanism where the detection module continuously monitors the environment, sends data to the control unit, and the control unit adjusts escalator operation accordingly. This closed-loop feedback system enables the escalator to adapt to various scenarios (pedestrian crossing, emergency situations, maintenance modes) through intelligent control rather than complex hardware
