Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a key or magnetic card is used to unlock door locks or switches, then security is maintained, but ease of operation deteriorates due to the need to carry specific keys/cards and risk of mistakes
Solution Approach 1:
The patent replaces the mechanical key/card insertion system with a wireless communication system. The host device uses a wireless transmission unit to communicate with the switch control device, eliminating the need for physical keys or magnetic cards. This substitution improves ease of operation while maintaining security through wireless authentication protocols.
Solution Approach 2:
The patent introduces a wireless communication system as an intermediary between the user and the door lock/switch control system. The host device acts as a mediator that transmits authentication information wirelessly to the switch control device, replacing the direct mechanical interaction with an intermediate wireless communication layer that simplifies user interaction while maintaining security.
2Ease of operation
If wireless communication is used for door control, then ease of operation is improved, but power consumption increases due to continuous wireless signal transmission and reception
Solution Approach 1:
The patent implements periodic action by having the host device and switch control device establish wireless connections only when needed (upon approach or authentication requirement) rather than maintaining continuous communication. The wireless transmission unit transmits authentication information on-demand, allowing the host device to enter low-power states between authentication events, thereby reducing overall power consumption while maintaining ease of operation.
3Reliability
If directional antennas are used for wireless communication, then security against incorrect operations is improved, but device complexity increases due to directional antenna requirements
Solution Approach 1:
The patent applies local quality by using directional antennas that focus wireless communication in specific directions toward the intended target (switch control device). This directional focus ensures that authentication signals are transmitted and received only in the intended location, preventing unauthorized access from other directions while using standard directional antenna technology that does not significantly increase overall system complexity.
Data Source
AI summary
A wireless control method includes steps as follows. A connection with an authentication device is built through a directional antenna of a wireless host device. Information, which is received by the wireless host device from the authentication device, is transmitted to a switch control device through a data transmission interface. The switch control device is utilized to control a switch according to the information, which is received by the wireless host device from the authentication device. The present invention also discloses a wireless host device and a switch control device.
