Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are integrated into wearable devices or swallowed capsules to obtain non-invasive measurements, then sensing ability is achieved, but size and weight increase
Solution Approach 1:
The patent combines the sensing element and signal processing component into a single integrated device structure, where the sensing element detects biosignals and the active component processes signals within the same flexible element, eliminating the need for separate sensor modules and reducing overall device weight
Solution Approach 2:
The sensing element and active component are nested within the flexible element structure, with the active component positioned adjacent to and integrated with the sensing element, creating a compact nested arrangement that minimizes device size and weight while maintaining sensing functionality
2Measurement precision
If non-invasive measurements are performed through sensors, then physical activity and health information can be obtained, but signal-to-noise ratio decreases due to weak signals and background noise
Solution Approach 1:
The patent extracts and removes noise from the detected biosignal through the active component, which processes the raw signal from the sensing element to separate the weak biosignal from background noise, thereby improving signal-to-noise ratio
Solution Approach 2:
The active component acts as an intermediary between the sensing element and the external system, processing and conditioning the biosignal to enhance its quality before transmission, thereby preserving information while eliminating noise
3Measurement precision
If sensors are used for non-invasive measurements, then health information can be obtained, but signal attenuation occurs during transmission
Solution Approach 1:
The active component performs preliminary signal processing and amplification immediately after the sensing element detects the biosignal, before the signal is transmitted outward, thereby compensating for potential attenuation and preserving signal strength
Solution Approach 2:
The patent replaces passive mechanical signal transmission with active electronic signal processing, where the active component electronically processes and amplifies the biosignal, eliminating signal attenuation that would occur in passive mechanical transmission systems
4Measurement precision
If traditional sensor integration methods are used, then sensing functionality is achieved, but device complexity and area increase
Solution Approach 1:
The patent merges the sensing element and signal processing component into a single integrated structure within the flexible element, reducing device complexity by eliminating separate modules and simplifying the overall system architecture
Solution Approach 2:
The flexible element serves multiple functions simultaneously: it provides the structural substrate, houses the sensing element for biosignal detection, and contains the active component for signal processing, thereby reducing device complexity through multi-functionality
