Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operation of deadbolt is used, then device complexity is reduced, but reliability of security is worsened due to human error and lack of electronic control redundancy
Solution Approach 1:
The door lock system automatically determines whether to lock or unlock based on motion detection and environmental sensor data, eliminating the need for manual user decisions. The system self-manages the locking state by detecting user presence and door opening/closing events, thereby improving reliability without requiring complex user interfaces or manual operation procedures.
Solution Approach 2:
The patent replaces manual mechanical operation of the deadbolt with an automated motor-driven mechanism controlled by electronic sensors and processors. The motor actuates the deadbolt based on signals from motion detectors and environmental sensors, substituting the mechanical hand-turn operation with an electromechanical system that improves reliability through automated control and electronic redundancy.
2Reliability
If electronic control is added to door lock, then reliability of security is improved, but ease of operation is worsened due to dependency on electronic controllers
Solution Approach 1:
The system automatically manages locking and unlocking operations based on sensor inputs, eliminating the need for users to manually operate electronic controls. The processor interprets sensor data and automatically actuates the motor to lock or unlock the deadbolt, making the system both reliable and easy to operate without requiring user interaction with electronic interfaces.
Solution Approach 2:
The system performs preliminary sensing and decision-making before actuation, continuously monitoring environmental conditions and motion patterns. By pre-processing sensor data and determining the appropriate locking state in advance, the system ensures reliable security control while maintaining ease of operation through automated, seamless execution without requiring user intervention at the moment of locking or unlocking.
3Ease of operation
If vibration sensing device is added to mobile device, then ease of operation is improved through remote control, but device complexity is worsened
Solution Approach 1:
The mobile device utilizes its existing vibration sensor, which serves multiple functions including game control, notification feedback, and now door lock control. By leveraging the multi-functionality of the vibration sensor, the system enables remote door locking/unlocking without adding dedicated hardware, thereby improving ease of operation while minimizing the increase in device complexity through software-based implementation.
