Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If general sensing devices are used to detect arterial acceleration pulse waves, then basic sensing function is achieved, but the ability to compare normal values with abnormal values is lacking
Solution Approach 1:
The patent implements a feedback mechanism by storing normal arterial acceleration pulse wave values in memory and comparing real-time detected values against these stored references. The system provides feedback through visual displays and audible signals when abnormalities are detected, enabling continuous health monitoring with automatic comparison and alerting functionality.
2Adaptability or versatility
If multi-functional sensing devices are added with comparison and alerting functions, then health monitoring applicability is enhanced, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single integrated device: the arterial acceleration pulse wave sensor, memory for storing reference values, processing unit for comparison, display device for visual output, and speaker for audible alerts are all combined into one cohesive system. This integration achieves multi-functionality without requiring separate devices for each function.
Solution Approach 2:
The sensing device is designed with universal health monitoring capabilities by incorporating reference value storage and automatic comparison functions that can detect various abnormal conditions (such as arrhythmia, hypertension indicators) using the same arterial acceleration pulse wave sensor, making the device adaptable to multiple health monitoring scenarios.

AI summary
A capacitive accelerometer device is provided, and includes a capacitive accelerometer module, a display device and a signal line. The capacitive accelerometer module includes one or more capacitive accelerometers for sensing an arterial acceleration pulse wave of a user. The display device includes a displayer and a speaker. The displayer is used to display the arterial acceleration pulse wave of the user. The speaker emits an audible signal according to a change value of the arterial acceleration pulse wave. The display device electrically connects to the capacitive accelerometer module via the signal line. The display device automatically senses the arterial acceleration pulse wave of the user and correspondingly generates the change value. The display device generates a prompt signal when the change value is equal to or larger than a predetermined value.
