Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If optical sensing principles are used for physiological data detection, then the device structure remains simple, but the measurement accuracy deteriorates
Solution Approach 1:
The patent replaces optical sensing principles with pressure sensing technology. Pressure sensors detect pulse beats through physical contact and generate pressure sensing signals, which are then processed to obtain physiological data. This substitution of sensing mechanism directly addresses the accuracy issue while maintaining device feasibility
Solution Approach 2:
The patent employs an air pump and airbag system to apply controlled pressure to the pressure sensors. The air pump inflates the airbag to press the sensors against the user's skin, ensuring consistent contact for accurate measurement. This pneumatic mechanism enables reliable pressure-based detection
2Volume of moving object
If space for accommodating sensors is reduced for compactness, then the device size decreases, but the sensor type diversity and measurement capability deteriorate
Solution Approach 1:
The patent uses a single pressure sensor that can detect multiple physiological parameters including pulse beats, blood pressure, and other vital signs. The pressure sensor serves multiple measurement functions, eliminating the need for various specialized sensors and maintaining device compactness while preserving measurement versatility
Solution Approach 2:
The patent changes the detection parameter from optical properties (light intensity) to mechanical properties (pressure). By measuring pressure changes at different locations and times, the system derives multiple physiological indicators from a single sensor type, expanding measurement capability without adding device volume

AI summary
The present invention is a pressure-sensitive smart electronic bracelet and its application method. The smart electronic bracelet comprises a first body, a second body, and a bracelet band. Two opposite sides of the first body are respectively connected to the second body and the bracelet band. The first body is equipped with an air pump, and the second body is equipped with multiple pressure sensors and an airbag, with each pressure sensor having a contact portion and the airbag connected to the air pump. When a user wears the bracelet and the airbag is inflated, each pressure sensor receives the user's pulse beats information through the contact portion to accordingly generate a pressure sensing signal, and each contact portion can further protrude from an outer surface of the second body to detect the user's blood pressure, pulse condition and other vital signs.
