Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional smart lock technologies are used, then the basic locking and unlocking function is provided, but the ability to accurately detect whether the lock is fully unlocked or locked is lacking
Solution Approach 1:
The patent divides the lock state detection into multiple discrete sensing positions (first position for unlocked state, second position for locked state, and third position for intermediate states). Each position has a dedicated sensing component that detects a specific trigger component position, enabling precise segmentation of the lock state detection process and improving measurement accuracy without creating a single complex detection system.
Solution Approach 2:
The patent introduces a trigger component as an intermediary element that carries detection marks at different positions. This trigger component rotates with the lock mechanism and serves as a mediator between the mechanical lock state and the sensing components. The detection marks on the trigger component enable the sensing components to accurately detect lock state without direct complex mechanical coupling.
2Reliability
If the controller continuously monitors lock state, then real-time detection is achieved, but power consumption increases
Solution Approach 1:
The patent implements periodic monitoring of lock state through the rotation of the trigger component. The sensing components are activated at specific periodic positions (first, second, and third positions) during the rotation cycle, rather than continuous monitoring. This periodic action maintains real-time detection capability while significantly reducing power consumption by keeping the sensing components in a low-power state between activation points.
Solution Approach 2:
The rotating component and trigger component serve themselves by their own motion. The rotation of the rotating component automatically positions the trigger component to pass by the sensing components, generating detection signals without requiring additional active monitoring or power consumption. The mechanical motion itself provides the detection mechanism.
3Measurement precision
If the lock system includes multiple sensing components for comprehensive state detection, then detection accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent designs the trigger component to serve multiple functions: it acts as a mechanical link between the rotating component and the sensing components, carries detection marks for different lock states, and enables the sensing components to detect both locked and unlocked states. This multi-functionality reduces the need for separate dedicated components for each detection function.
Solution Approach 2:
The patent places sensing components at specific local positions (first position, second position, third position) around the rotation path. Each sensing component is optimized for detecting a specific local state, and the trigger component has detection marks positioned accordingly. This localized approach allows accurate detection without requiring sensing components throughout the entire rotation path, reducing overall device complexity.

AI summary
This disclosure provides a lock having a rotating component, the rotation of which drives the retractable movement of a latch bolt, and the rotating component is equipped with a trigger component; a first sensing component, fixedly set or arranged at the first position of the lock, where the first position is the position indicated by a knob fixedly connected to the rotating component when the lock is in the unlocked state, and when the trigger component is at the first position, the first sensing component generates a first trigger signal; a second sensing component is fixedly set or arranged at the second position of the lock, where the second position is the position indicated by the knob when the lock is in the locked state, and when the trigger component is at the second position, the second sensing component generates a second trigger signal.
