Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all necessary sensors are installed in the mobile electronic device, then comprehensive sensing results can be obtained, but the device size and power consumption increase
Solution Approach 1:
The sensing system is divided into two segments: a host device that performs data processing and analysis, and detachable sensors that perform physical sensing. This segmentation allows the mobile electronic device to offload sensor functionality to external detachable sensors, reducing device size while maintaining comprehensive sensing capabilities through the host device connection.
Solution Approach 2:
A connecting interface serves as an intermediary between the host device and detachable sensors. This intermediary enables communication and data transfer between the host device and external sensors, allowing comprehensive sensing results to be obtained without installing all sensors directly in the mobile device.
2Measurement precision
If all necessary sensors are installed in the mobile electronic device, then comprehensive sensing results can be obtained, but power consumption increases
Solution Approach 1:
The system segments sensing functions from the mobile electronic device and places them in separate detachable sensors. Only the host device remains active for data processing, while detachable sensors can be activated only when needed and connected, significantly reducing overall power consumption while maintaining comprehensive sensing capabilities.
Solution Approach 2:
The connecting interface acts as an intermediary that enables power-efficient communication between the host device and detachable sensors. The host device can control when detachable sensors are activated and retrieve data only when needed, avoiding continuous power consumption.
3Measurement precision
If the electronic device is tightly connected to the user, then accurate physical state sensing can be obtained, but the device cannot be detached when needed
Solution Approach 1:
The connection between the host device and sensors is made dynamic through detachable sensors with connecting interfaces. The connection state can change from attached to detached based on user needs, allowing the system to adapt between maintaining tight contact for accurate sensing and being detached when the device is not needed, thus resolving the contradiction between sensing accuracy and detachability.

AI summary
A sensing system is provided. The system includes an electronic device and a detachable sensor. The detachable sensor could be connected to the electronic device through a connecting interface. When the electronic device detects that the detachable sensor is connected to the electronic device, the electronic device obtains a plurality of sensing data, and transforms the sensing data into a plurality of sensing results. Also, when the electronic device is connected to a host device, the electronic device sends the sensing results to the host device.
