Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple physical metal keys are used for different locks, then locking and unlocking functionality is achieved, but key organization becomes difficult and space is occupied
Solution Approach 1:
The patent merges multiple physical keys into a single electronic key device that can store and manage multiple electronic secret keys. The electronic key integrates the functionality of numerous separate physical keys, allowing users to access multiple locks with one unified device, thereby eliminating the need to carry and organize multiple separate keys.
Solution Approach 2:
The patent uses electronic secret keys as digital copies of traditional physical keys. Instead of relying on physical metal keys with unique cuts and shapes, the system creates electronic representations of key functionality that can be stored, copied, and managed digitally, significantly reducing the physical space required for key storage.
2Reliability
If conventional locks with multiple components are used, then locking and unlocking mechanisms are achieved, but production complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts the power source from the lock itself and relocates it to the electronic key. This extraction eliminates the need for complex internal power management components within the lock, simplifying the lock's structure while maintaining functionality. The lock becomes a passive authentication device that relies on the key for power and authentication.
Solution Approach 2:
The patent replaces traditional mechanical locking components (lock pins, sliders, shafts, cams) with an electronic authentication system. Instead of mechanical key-cam interactions, the system uses electronic secret key verification through electrical connection, substituting complex mechanical assemblies with simpler electronic circuits and authentication logic.
3Adaptability or versatility
If electronic locks with computer assistance for setting are used, then pairing configuration is achieved, but setting convenience deteriorates
Solution Approach 1:
The patent implements self-service pairing between the electronic key and electronic lock. When the electronic key is inserted into the electronic lock, the system automatically performs authentication and establishes the pairing relationship without requiring external computer assistance or manual configuration. The devices autonomously complete the pairing process through their built-in communication and authentication protocols.
4Duration of action of stationary object
If power source is built into the electronic lock, then continuous operation is achieved, but reliability and safety rate decrease
Solution Approach 1:
The patent inverts the traditional power source arrangement by placing the power source in the mobile electronic key rather than in the stationary electronic lock. This inversion allows the lock to remain a passive, powerless device that only activates when authenticated by the key. The power source travels with the key, eliminating the security risks associated with having a power source and storage in the lock itself.
