Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual button press or swipe operation is used to control terminal screen locking, then the terminal can be locked or unlocked, but the operation process is slow and consumes more power
Solution Approach 1:
The patent replaces manual mechanical operations (button pressing, swiping) with electromagnetic signal transmission through human body communication. The wearable device transmits electromagnetic signals that pass through the user's body to the terminal, enabling automatic locking control without mechanical user input, thereby improving speed and reducing power consumption.
Solution Approach 2:
The system enables self-service locking by detecting when the terminal is placed in the wearable device through automatic electromagnetic signal recognition. The terminal automatically locks itself when it detects the presence of the wearable device, eliminating the need for active user control actions and reducing overall power consumption.
2Ease of operation
If manual unlocking operation is performed on terminal screen, then the screen can be unlocked, but the operation requires user interaction which increases power consumption
Solution Approach 1:
The patent replaces manual unlocking operations with electromagnetic signal-based automatic unlocking. When the wearable device is removed from the terminal or a specific signal is transmitted, the terminal automatically unlocks through electromagnetic communication, eliminating the need for manual screen interaction and associated power consumption.
Solution Approach 2:
The human body acts as an intermediary medium for transmitting electromagnetic signals between the wearable device and terminal. The user's body conducts the electromagnetic signals during the unlocking process, enabling contactless and automatic unlocking without direct manual operation on the terminal screen.
3Reliability
If traditional locking method is used, then screen locking can be achieved, but unintended touch operations may occur increasing power consumption
Solution Approach 1:
The patent eliminates mechanical touch-based locking control by using electromagnetic signal transmission through the body. The wearable device sends specific electromagnetic signals that are uniquely recognized by the terminal, ensuring accurate locking control without the risk of unintended touch operations, thereby improving reliability and reducing unnecessary power consumption.
