Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional interfaces are used for wearable devices, then device functionality is provided, but user interaction intuitiveness and convenience are insufficient
Solution Approach 1:
The patent replaces conventional mechanical touch interfaces with a capacitive sensing system that detects electrical signals through the human body. The wearable device uses capacitive sensors to detect touch inputs, gestures, and body movements by measuring changes in electrical capacitance, eliminating the need for physical buttons or screens while improving ease of operation.
Solution Approach 2:
The patent introduces the human body as an intermediary medium for interaction. The body acts as a conductor that transmits electrical signals from the user's gestures and touches to the wearable device's capacitive sensors, enabling intuitive control without direct mechanical contact with traditional interface elements.
2Measurement precision
If the terminal measures distance and senses contact using capacitive sensing, then touch input detection precision is improved, but device complexity increases
Solution Approach 1:
The patent makes the capacitive sensing system serve multiple functions: detecting touch inputs, measuring distance, recognizing gestures, and sensing body movements. By using a single capacitive sensing mechanism for various detection tasks, the system achieves high measurement precision without proportionally increasing device complexity.
Solution Approach 2:
The patent detects different types of inputs by measuring changes in electrical capacitance parameters. The system distinguishes between various touch inputs, distances, and gestures by analyzing variations in capacitance values, enabling precise detection through parameter analysis rather than requiring separate sensors for each function.

AI summary
A touch input method, a terminal contacting a first body part, a non-transitory computer-readable storage medium, and a chipset are provided. The touch input method includes receiving, by a terminal contacting a first body part, a touch input applied by a second body part; measuring a distance between the terminal and the second body part; sensing, by the terminal, whether the second body part contacts the first body part; and determining input information for controlling the terminal, based on the measured distance between the terminal and the second body part and changed information of an electrical signal transmitted from the terminal to the first body part.
