Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a measurement portion is immersed into suspension liquid for diffuse reflected light measurement, then measurement can be performed on suspension liquids, but the measurement portion becomes complicatedly structured and suspension liquid adheres to and contaminates the measurement portion
Solution Approach 1:
The invention extracts the measurement function from a complex immersed probe structure and relocates it to a simple external configuration. The light source and detector are positioned outside the suspension liquid flow path, with light passing through the pipe wall to measure the liquid without physical contact, thereby eliminating contamination and structural complexity while maintaining measurement capability
2Ease of operation
If light is transmitted through window material for measurement, then non-contact measurement is enabled, but light absorption by window material and reflected light at surfaces affect measurement accuracy
Solution Approach 1:
The invention introduces a variable mechanism that dynamically adjusts the angle and position of light irradiation and detection relative to the pipe window. This allows the optical system to adapt to different pipe geometries, materials, and suspension liquid properties, optimizing the measurement path to minimize window material absorption and reflection effects while maintaining non-contact measurement capability
Solution Approach 2:
The invention changes the parameters of light irradiation (angle, position, wavelength) and detection to optimize measurement conditions. By varying these parameters, the system can compensate for window material effects and adapt to different measurement scenarios, thereby maintaining high measurement accuracy in non-contact configuration
3Adaptability or versatility
If probe structure is designed in advance for various pipes and suspension liquids, then comprehensive measurement coverage is achieved, but duration and cost increase
Solution Approach 1:
The invention creates a universal measurement system with adjustable optical parameters that can measure various pipe types, shapes, and suspension liquids using a single standardized probe design. The variable mechanism allows one probe to adapt to multiple measurement conditions, eliminating the need for custom-designed probes for each application and significantly reducing design and manufacturing time and cost

AI summary
To provide: a device which performs spectroscopic measurement on a suspension liquid handled in the field of pharmaceutical products, foods, or chemistry without taking out the suspension liquid from the inside of a pipe, and is capable of accurate measurement even when the device is attached to pipes of various shapes and materials; and a measurement condition adjustment method, the following configuration is adopted. A measurement device for measuring an optical spectrum of a liquid flowing in a pipe provided with a window material includes: a measurement probe having a light irradiation unit and a light reception unit; and a movement mechanism for moving the measurement probe, in which the movement direction of the measurement probe includes a rotation angle for changing the direction of the probe and a direction different from the axial direction of the pipe. The position of the measurement probe is adjusted by using both or one of the S/N ratio and the intensity of the measured values at the wavelength of interest.
