Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fingerprint identification module is arranged on the handle of the smart lock, then the operation is easy, but the design is not suitable for smart locks without handles
Solution Approach 1:
The fingerprint identification module is integrated into the cover structure that can be universally applied to both smart locks with handles and without handles. The cover serves multiple functions: it shields the keyhole and charging port while also providing a mounting position for the fingerprint module, making the design adaptable to different lock types.
Solution Approach 2:
The fingerprint identification module is positioned on the front surface of the cover rather than on the handle, utilizing the front surface dimension. This dimensional relocation allows the module to be accessible and operable on smart locks without handles, while maintaining ease of operation through its prominent front-facing position.
2Shape
If the cover shields the keyhole and charging port, then the appearance is enhanced, but the structure becomes more complex
Solution Approach 1:
The shield cover integrates multiple functions into a single component: it shields the keyhole, shields the charging port, and provides a mounting structure for the fingerprint identification module. By merging these functions into one cover assembly, the design enhances appearance while minimizing the increase in structural complexity compared to separate components.
3Volume of moving object
If the fingerprint module is positioned in the through hole of the front cover, then the volume is reduced, but the wiring becomes more complex
Solution Approach 1:
A wire hole is provided in the rear plate at a position corresponding to the insertion shaft, serving as an intermediary pathway for the wire. The wire extends through this wire hole to connect the circuit in the lock body to the fingerprint identification module, simplifying the wiring route compared to routing wires through the front cover or handle area.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for a compact design with reduced holes in other parts, enhancing the appearance while maintaining simple and convenient operation, and ensuring effective shielding of the lock body's keyhole and charging port.
Implementation Method 1
an elastic resetting assembly positioned between the insertion shaft and the lock body, the elastic resetting assembly including a connecting portion coupled with the insertion shaft and a spring provided between the connecting portion and the lock body
Implementation Method 2
a magnetic attraction assembly mounted on the cover and the lock body, the magnetic attraction assembly comprises a plurality of grooves provided on a rear end face of the cover, each of the plurality of grooves is equipped with a first magnet, and a second magnet is correspondingly provided on the lock body which is located at a rear side of the first magnet
