Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional electronic locks use battery power, then the lock can operate independently, but the batteries need frequent replacement which is inconvenient and creates security risks
Solution Approach 1:
The door lock performs self-charging through wireless power transmission from the gateway. The lock contains a power receiving unit that automatically receives power wirelessly when positioned near the gateway, eliminating the need for manual battery replacement and ensuring continuous operation.
Solution Approach 2:
The gateway acts as an intermediary power source between the external power supply and the door lock. It contains a power transmitting unit that wirelessly transmits power to the lock, serving as a mediator that eliminates direct battery dependency while ensuring reliable power supply.
2Adaptability or versatility
If electronic locks use traditional battery power, then the structure can be simple, but the design is limited and maintenance is required
Solution Approach 1:
The gateway serves multiple functions: it acts as a communication interface, a power transmitting station, and a backup power source. The door lock similarly integrates power receiving, processing, and storage functions, making the system more adaptable and versatile while eliminating structural limitations of battery-based designs.
Solution Approach 2:
The power receiving unit and power processing unit are integrated within the door lock structure, with the power receiving unit nested inside the lock body and the power processing unit connected to both the receiving unit and the existing battery system, creating a layered integrated design.
3Duration of action of stationary object
If wireless charging components are integrated into the lock, then battery replacement is eliminated, but the device complexity increases
Solution Approach 1:
The wireless power system is divided into separate functional modules: a power transmitting unit in the gateway and a power receiving unit in the door lock. This segmentation allows each module to be optimized independently and simplifies the overall system integration while ensuring continuous operation.

Implementation Method 1
The first antenna unit outputs the direct current charging pulse wave to generate a magnetic electric field, so that the second antenna unit induces or resonates the magnetic electric field to obtain an induced signal
Implementation Method 2
The first signal-processing unit sends the identification signal to the first antenna unit. The first antenna unit transmits the identification signal to the second antenna unit

AI summary
A lock wireless charging system includes a gateway (10) and a door lock (20). The gateway (10) includes a first micro-processing unit (101), a first signal-fetching unit (102), a first charging unit (103), a first signal-processing unit (104) and a first antenna unit (105). The door lock (20) includes a second micro-processing unit (201), a second signal-fetching unit (202), a second charging unit (203), a second signal-processing unit (204), a second antenna unit (205) and a storage unit (206). The first antenna unit (105) outputs the identification and sensing signals. The door lock (20) fetches and transmits the identification signal to the second micro-processing unit (201) to determine. The second micro-processing unit (201) responds to the first micro-processing unit (101) with a responsive identification signal. If the identification is successful, the sensing signal is converted into electricity, so the second charging unit (203) charges the storage unit (206).
