Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If battery device and communication device are integrated in the lockset, then the lockset can provide power supply and communication functions, but the lockset volume increases and repair difficulty increases
Solution Approach 1:
The patent divides the lockset into separate functional modules: the lock body contains only the locking mechanism, while power supply and communication functions are provided by external devices connected through a physical interface. This segmentation reduces the lockset volume while maintaining all necessary functions.
Solution Approach 2:
The patent extracts the battery device and communication device from the lockset and places them outside. The lockset only retains the essential locking function, while external devices provide power and communication through a standardized physical interface, thereby reducing volume and improving repairability.
2Adaptability or versatility
If battery device and communication device are integrated in the lockset, then the lockset can provide power supply and communication functions, but the lockset repair difficulty increases
Solution Approach 1:
By separating the lockset into independent modules (locking mechanism, power interface, communication interface), each module can be repaired or replaced independently. The physical interface allows external devices to be connected or disconnected without affecting the lock body, significantly improving repairability.
Solution Approach 2:
The patent extracts power supply and communication components from the lockset, placing them in separate replaceable modules. This allows technicians to repair or replace only the faulty component rather than the entire lockset, reducing repair time and cost.
3Adaptability or versatility
If all functions are configured in the lockset, then the lockset can operate independently, but the cost increases
Solution Approach 1:
The patent designs a universal physical interface that can connect to various external devices for power supply and communication. This standardized interface allows the same lockset to work with different external devices, reducing development costs and enabling mass production while maintaining independent operation capability.
