Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spectrometers are limited in analyzing luminescent samples as they rely on light attenuation, which is not applicable to samples that emit their own radiation, and lack the capability to measure photoluminescent or chemiluminescent samples effectively.
Innovation Solution
A portable measuring device equipped with a housing, sample container, illuminating device, radiation receiver, and evaluation device, featuring a camera and control system for capturing and analyzing luminescent samples, allowing for wireless data transmission and storage of measurement data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional spectrometers use light attenuation measurement method, then they can measure non-luminescent fluid samples, but they cannot measure luminescent samples that emit their own radiation
Solution Approach 1:
The measuring device is designed to perform multiple measurement functions: it can measure both non-luminescent samples using light attenuation (spectrophotometry) and luminescent samples using radiation detection. The device includes a light source for illuminating non-luminescent samples and a radiation receiver for detecting luminescence from luminescent samples, making it a universal measuring instrument that adapts to different sample types without requiring separate specialized equipment.
2Measurement precision
If spectrometers measure light beam attenuation through samples, then they determine analyte concentration in non-luminescent samples, but the method fails for samples that emit their own radiation
Solution Approach 1:
The device uses an illuminating device as an intermediary to excite luminescent samples to emit radiation, which is then detected by the radiation receiver. For non-luminescent samples, the same illuminating device provides light that passes through the sample, and the radiation receiver detects the transmitted light. This intermediary illumination approach allows the device to measure different sample types through different physical mechanisms while using a unified hardware platform.
3Ease of operation
If a portable measuring device is designed with integrated components, then it achieves compactness and portability, but adding camera and data recording functions increases device complexity
Solution Approach 1:
The device merges multiple functions into a single integrated portable unit: the measuring head combines the radiation receiver, illuminating device, and evaluation electronics; the base part integrates the camera, microphone, display, and control unit; and these components communicate through wireless or wired connections. This merging approach maintains portability while adding documentation capabilities, as the camera and microphone are integrated into the handheld base part rather than requiring separate external devices.
Solution Approach 2:
The control unit serves multiple functions: it controls the illuminating device and radiation receiver for measurements, processes measurement data, controls the camera and microphone for documentation, and manages wireless data transmission. This multi-functional control unit reduces the need for separate dedicated controllers for each function, thereby managing device complexity while providing comprehensive capabilities.
4Loss of information
If measuring device includes camera and microphone for documentation, then it enhances field measurement capability, but it increases power consumption and energy source requirements
Solution Approach 1:
The camera and microphone are activated periodically or on-demand based on measurement events rather than continuously. The control unit triggers the camera to capture images or video at specific measurement moments and activates the microphone for voice documentation when needed, rather than keeping these components running continuously. This periodic activation significantly reduces power consumption compared to continuous operation while still providing comprehensive documentation of measurement contexts.
