Solution Overview
Problem
Existing smart wearable devices suffer from inaccurate and incomplete health data detection due to the placement of detection chips on the back of the wrist, which is not the optimal position for detecting human health parameters, and the design compromises wearing comfort.
Innovation Solution
A wearable detection device with a flexible circuit board and ring-shaped chips positioned on a belt system that connects on the inner side of the wrist, allowing for accurate detection of parameters like pulse, heart rate, and blood pressure while enhancing comfort through a flexible material and secure buckle mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the detection chip is placed on the back of the wrist to ensure contact with the body, then the device structure is simple, but the detection accuracy deteriorates because the back of the wrist is not the optimal position for detecting health parameters
Solution Approach 1:
The device is divided into a main body and a separate detection component (detection chip on the band). The detection chip is segmented from the main body and placed at the optimal detection position on the wrist, allowing accurate health parameter detection while keeping the main body structure simple.
Solution Approach 2:
A flexible band serves as an intermediary carrier to transport the detection chip from the main body to the optimal detection position on the wrist. The band acts as a mediator that connects the detection chip to the user's wrist without requiring the main body to directly contact the detection site.
2Measurement precision
If the detection chip protrudes from the device body to ensure full contact with the human body, then the detection coverage is improved, but the wearing comfort deteriorates
Solution Approach 1:
The detection chip is mounted on a flexible band made of soft material that can conform to the wrist's contour. This flexible structure provides full contact with the skin for accurate detection while eliminating the discomfort caused by rigid protruding chips.
Solution Approach 2:
The detection chip and band are designed with a curved profile that matches the natural contour of the wrist. This curvature allows the detection chip to make full contact with the skin surface while maintaining a comfortable, non-intrusive fit that does not protrude awkwardly.
3Measurement precision
If the detection chip is positioned at the arterial position for accurate detection, then the detection accuracy is improved, but the device design becomes more complex
Solution Approach 1:
The detection chip is designed with a dynamic conduction mechanism that is activated only when the band is buckled onto the wrist. The chip transitions from a non-conducting state during storage/transport to a conducting state during use, automatically adapting to the operational condition without requiring complex external control.
Solution Approach 2:
The detection chip's conduction state is automatically determined by the mechanical condition of the band buckling. The system self-regulates the chip's activation based on whether the device is being worn or stored, eliminating the need for external switches or complex control circuits.
4Measurement precision
If multiple to-be-conducted chips are disposed in the first belt body for complete health parameter detection, then the detection completeness is improved, but the device complexity increases
Solution Approach 1:
Multiple detection chips are integrated into a single flexible band, allowing the device to perform multiple health parameter detections (pulse, blood pressure, temperature, etc.) simultaneously. The flexible circuit board provides a universal platform that can accommodate various types of detection chips in a compact arrangement.

AI summary
A wearable detection device includes a main body, a first belt body, and a second belt body. The first belt body and the second belt body are connected to two sides of the main body. The main body includes a power source, a control circuit connected to the power source, and a processor connected to the control circuit. The wearable detection device further includes a flexible circuit board and a plurality of to-be-conducted chips. The flexible circuit board is disposed in the first belt body and is connected to the main body. The plurality of to-be-conducted chips are disposed in the first belt body and are connected to the flexible circuit board. When the first belt body and the second belt body are interconnected, the to-be-conducted chip positioned at a junction point is connected.
