Engineering Contradiction Analysis
1Duration of action of moving object
If a non-user changeable battery is built-in for continuous monitoring, then the device provides continuous monitoring capability, but the battery life is limited and cannot be extended by user intervention
Solution Approach 1:
The device is divided into separable modules: a main body unit and interchangeable wristband modules. Each wristband module contains its own battery, allowing users to replace just the wristband module when the battery is depleted, rather than replacing the entire device or dealing with built-in battery constraints.
Solution Approach 2:
The system allows changing the battery parameter by providing multiple wristband modules with different battery capacities or types. Users can select and attach wristbands with appropriate battery characteristics based on their needs, effectively changing the power supply parameters of the device.
2Reliability
If the device structure is fixed for continuous monitoring, then the monitoring function is stable, but the device cannot adapt to different user requirements or peripheral additions
Solution Approach 1:
The main body unit is designed with universal interfaces and standardized connection mechanisms that can accommodate multiple types of wristband modules and peripheral devices. This allows a single core unit to serve multiple functions and adapt to different user requirements while maintaining stable monitoring capabilities.
Solution Approach 2:
The device structure transitions from fixed to dynamic through the interchangeable wristband modules. Users can attach, detach, and swap modules based on their current needs, making the device configuration adaptable while the core monitoring function remains stable and reliable.
3Reliability
If sensors are permanently integrated for activity sensing, then the sensing function is reliable, but the device cannot accommodate additional sensors or modified sensing requirements
Solution Approach 1:
Sensing functions are segmented between the main body unit (which contains core processing and stable sensors) and the interchangeable wristband modules (which can contain additional or different sensors). This segmentation allows reliable core sensing while enabling flexible addition of specialized sensors through module replacement.

AI summary
A wearable device for sensing and transmitting physical activities of a user to a computing device is provided. The wearable device includes a first wristband worn around the wrist of the user, a left connecter assembly attached to the first wristband, a center assembly having sensors for sensing physical activities of the user attached to the left connecter assembly, a right connecter assembly attached to the center assembly and a second wristband worn interchangeably on the exhaustion of the primary battery inside the center assembly. The center assembly includes one or more sensors for sensing user activities. Examples of sensors include but not limited to heart rate sensor and the galvanic sensor. Further, the center assembly also includes a finger sensor to measure heart rate.
