Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional key-operated locking core cylinders are used, then physical security is maintained through mechanical key control, but convenience is reduced due to the need for physical keys and limited access methods
Solution Approach 1:
The patent replaces the traditional mechanical key-based locking system with a wireless electronic system. The locking core cylinder integrates a wireless receiver, processor, and motor that communicate with portable electronic devices via wireless signals. This substitution eliminates the need for physical keys while maintaining security through electronic authentication and proximity-based access control.
Solution Approach 2:
The locking core cylinder is designed to perform multiple functions: it serves as both a traditional locking mechanism and a wireless communication device. The same cylinder body houses both mechanical locking components and electronic wireless components, allowing it to operate in both key-based and keyless modes, thereby providing universal access methods.
2Ease of operation
If wireless-enabled interchangeable locking core cylinders are developed, then keyless operation and convenience are improved through Bluetooth technology and pattern-based authentication, but device complexity increases due to integration of wireless components
Solution Approach 1:
The patent merges the wireless communication components (receiver, processor, antenna) directly into the existing locking core cylinder structure. By combining the electronic authentication system with the mechanical locking mechanism in a single integrated unit, the design avoids the complexity of separate wireless locking systems while maintaining ease of operation through keyless access.
3Reliability
If pattern-based authentication is implemented, then security is enhanced through multiple authentication factors, but ease of operation is reduced due to the need for pattern input
Solution Approach 1:
The system uses pattern-based authentication as an intermediary step between the user and the locking mechanism. Instead of requiring physical key insertion or complex multi-step verification, users simply draw a pattern on a touch-sensitive surface, which the system translates into an authentication signal. This intermediary pattern input method balances security with ease of operation.

AI summary
A wireless, electronic interchangeable locking core that includes an outer housing and a locking core that is rotatable via an external handle between a locked position and an unlocked position. The handle is prevented from rotating the locking core unless wirelessly-provided authorization credentials are validated and/or a pattern of physical input interactions with an electronic sensor is matched with a stored pattern. The pattern may be defined, for example, as a sequence of short and long interactions with a button, light sensor, touch panel, or the like. The electronic interchangeable locking core may include a battery and be configured for installation in small format interchangeable core (SFIC) housings.
