Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional instrumentation and devices are used for sensing health factors and materials, then sensing capabilities are provided, but the devices become bulky, slow, inaccurate, and expensive
Solution Approach 1:
The patent combines conventional sensing instrumentation with a smartphone platform, integrating optical transmitters, optical receivers, and processing circuits into a unified handheld device. This merging allows the system to achieve laboratory-grade measurement precision while eliminating the bulkiness of separate conventional instruments, as the smartphone provides the computational power and user interface in a compact form factor.
Solution Approach 2:
The sensing device is designed as a multi-functional platform that can perform various types of sensing (optical, biometric, material composition) using a single integrated system. The smartphone's general-purpose computing capabilities combined with specialized sensing components allow the device to adapt to multiple sensing applications, reducing the need for multiple separate specialized instruments and thereby reducing overall device complexity and bulkiness.
2Ease of operation
If conventional instrumentation is used for materials sensing, then sensing functionality is provided, but the devices are too slow and expensive for everyday use
Solution Approach 1:
The system leverages the smartphone's existing capabilities (processor, display, user interface) to perform sensing operations autonomously. The smartphone's built-in processing power rapidly analyzes spectral data and provides immediate results without requiring external computing equipment or manual data processing, thereby increasing sensing speed while maintaining ease of operation through the familiar smartphone interface.
Solution Approach 2:
The patent replaces traditional mechanical or manual sensing systems with electronic and optical sensing combined with digital processing. The optical transmitter and receiver use electromagnetic fields rather than mechanical contact, and the smartphone's digital processor rapidly analyzes the data, eliminating the slowness associated with conventional manual or mechanical sensing methods while providing results instantly through the smartphone display.
3Adaptability or versatility
If conventional sensing devices are used, then measurement capabilities are provided, but they fail to leverage smartphone functionality and convenience
Solution Approach 1:
The patent introduces supplemental circuitry as an intermediary between the optical components and the smartphone's processing systems. This intermediary layer includes circuits for transmitting optical signals, receiving reflected light, converting optical signals to electrical signals, and processing the data before presenting it to the smartphone's display and processing capabilities. This intermediary ensures reliable measurement while fully leveraging the smartphone's versatility and user interface.
