Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual signaling (button pushing) is used for elevator control, then the system is simple and easy to operate, but it is inefficient and inappropriate for certain users or security environments
Solution Approach 1:
The patent replaces manual mechanical button pushing with automated optical sensing systems. Depth sensors capture 3D sensor data to automatically detect passenger presence, position, and intent without requiring physical interaction with buttons, thereby improving efficiency while reducing mechanical operation requirements
Solution Approach 2:
The system enables self-service operation where the elevator automatically detects and responds to passenger needs without manual signaling. The depth sensing system autonomously identifies passenger intent and triggers appropriate elevator responses, eliminating the need for users to manually press buttons
2Measurement precision
If depth sensors and biometric data are used for passenger tracking, then destination accuracy and security are improved, but system complexity and data processing requirements increase
Solution Approach 1:
The depth sensing system serves multiple functions simultaneously: it detects passenger presence, determines passenger position, recognizes passenger intent, and provides security verification. This multi-functionality achieves high measurement precision while avoiding the need for separate specialized devices for each function
Solution Approach 2:
The patent combines depth sensing data with biometric data processing in an integrated system. The control system merges information from multiple sensor types to achieve accurate passenger identification and destination recognition, reducing overall system complexity through consolidation
3Reliability
If automated passenger tracking and alerting systems are implemented, then security and passenger experience are enhanced, but the system requires more sophisticated processing and monitoring capabilities
Solution Approach 1:
The system implements continuous feedback loops where depth sensors monitor passenger movement in real-time, the control system processes this data to track passenger progress toward the destination, and alerting mechanisms provide feedback to passengers about their routing status. This automated feedback system enhances reliability while managing complexity through systematic information flow
