Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate sensor devices are used for different measurements, then each device can be optimized for its specific function, but the device size and complexity increase
Solution Approach 1:
The patent combines multiple sensor devices (optical sensor, temperature sensor, electrical sensor) into a single integrated sensor device with a common housing and shared components. This merging approach enables multiple measurements to be performed simultaneously on the same target with a single device, reducing overall system complexity while maintaining versatility
Solution Approach 2:
The sensor device is designed with multi-functionality by incorporating different types of sensors (optical, temperature, electrical) that can perform various health-related measurements. The device can simultaneously determine optical measurements, temperature, and electrical properties, making it a universal measurement tool
2Measurement precision
If separate sensor devices are used for different measurements, then each measurement can be optimized independently, but spatial misalignment and temporal discrepancies occur
Solution Approach 1:
By merging multiple sensors into a single device with a common housing, the patent ensures that all sensors are positioned at the same location and perform measurements simultaneously on the same target. This eliminates spatial misalignment and temporal discrepancies that would occur with separate devices, improving both measurement precision and reliability
Solution Approach 2:
The sensor device automatically performs multiple measurements simultaneously without requiring external coordination or alignment procedures. The integrated design ensures that all sensors operate together as a unified system, self-correcting potential alignment and timing issues
3Adaptability or versatility
If multiple separate sensor devices are used, then comprehensive measurements can be obtained, but costs and device size increase
Solution Approach 1:
The patent merges multiple sensor devices into a single integrated unit, combining optical sensors, temperature sensors, and electrical sensors in one housing. This reduces the total weight and size compared to using separate devices, while maintaining the ability to perform comprehensive health-related measurements
Solution Approach 2:
The sensor device employs a nested structure where smaller sensors are positioned within or alongside larger components. For example, temperature and electrical sensors are integrated within the same housing and operational framework as the optical sensor, creating a compact nested arrangement that minimizes overall device size
