Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent introduces an intermediary device that maintains both analog and digital forms of sensing data simultaneously. This intermediary acts as a bridge between analog biological information sensors and digital processing systems, allowing data to be converted to digital form for compatibility while preserving the original analog signal characteristics for accurate measurement and synchronization.

Inventive Principle:
