VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional electronic lock uses multiple driven wheels, torsion springs, and sensor switches to achieve manual and automatic operation, then the functionality and user-friendliness are improved, but the device complexity and manufacturing cost increase

Engineering Contradiction:
Improvemanual and automatic operation capabilityVSAvoidconfiguration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates unnecessary components from the conventional electronic lock system. Specifically, it removes the first driven wheel, second driven wheel, torsion spring, and sensor switches that were present in the prior art. The simplified design achieves manual and automatic operation capability through a more streamlined configuration that does not require these multiple separate components, thereby reducing device complexity while maintaining versatility

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges multiple functions into a simplified integrated system. Instead of using separate driven wheels and torsion springs for manual and automatic operation, the invention combines these functions into a unified mechanism that achieves the same operational versatility with fewer parts, thereby reducing overall configuration complexity

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If a conventional electronic lock uses multiple driven wheels, torsion springs, and sensor switches to achieve manual and automatic operation, then the functionality is improved, but the manufacturing cost increases

Engineering Contradiction:

AI summary

An electronic lock includes a deadbolt, a driver mechanism, a transmission mechanism and a control mechanism. The transmission mechanism includes a transmission gear that is driven by the driver mechanism to rotate, a resilient unit that is mounted to and co-rotatable with the transmission gear, and a rotary member that is operable to rotate relative to the transmission gear between a locking position and an unlocking position, and that is connected to the deadbolt. The control mechanism is connected to the rotary member, and ceases operation of the driver mechanism when detecting that the rotary member has been rotated to one of the locking and unlocking positions.
