Solution Overview
Problem
Conventional particle size distribution analyzers face challenges with poor operability due to inadequate sealing, leading to instability in measurements caused by air currents and temperature changes, and require laborious optical alignment and maintenance, limiting the introduction of new measurement formats and precision.
Innovation Solution
A particle size distribution analyzer with a sealed construction separating the cell storage space from the equipment storage space, featuring a base construction body with separate cases for the light source and detector, and a cell support mechanism allowing for easy cell exchange and flexible measurement formats, along with a light track adjustment mechanism for precise optical alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cell storage space is surrounded by other equipment in a single case construction, then the device structure is compact, but access to the sample chamber is limited and operability deteriorates
Solution Approach 1:
The device is divided into two separate cases: the first case houses the light source, light detectors, and optical equipment, while the second case (sample chamber) houses the cell storage space. This segmentation allows independent access to the sample chamber from the front without interfering with the optical equipment, thereby improving operability while maintaining a compact overall structure.
2Reliability
If the cell storage space is not sealed from the equipment storage space, then construction is simpler, but air currents and temperature changes cause measurement instability
Solution Approach 1:
The device is divided into two separate cases: the first case houses the light source, light detectors, and optical equipment, while the second case (sample chamber) houses the cell storage space. This segmentation allows independent access to the sample chamber from the front without interfering with the optical equipment, thereby improving operability while maintaining a compact overall structure.
3Ease of repair
If optical equipment is housed in a single case with the sample chamber, then the device is more compact, but maintenance and alignment become laborious
Solution Approach 1:
The device is divided into two separate cases: the first case houses the light source, light detectors, and optical equipment, while the second case (sample chamber) houses the cell storage space. This segmentation allows independent access to the sample chamber from the front without interfering with the optical equipment, thereby improving operability while maintaining a compact overall structure.
4Adaptability or versatility
If the sample chamber is removed and exchanged for new measurement formats, then new formats can be introduced, but the operation becomes more complex and time-consuming
Solution Approach 1:
The device is divided into two separate cases: the first case houses the light source, light detectors, and optical equipment, while the second case (sample chamber) houses the cell storage space. This segmentation allows independent access to the sample chamber from the front without interfering with the optical equipment, thereby improving operability while maintaining a compact overall structure.

AI summary
In a measurement system, by suppressing the environmental changes of counter-flow of air, and temperature changes and the like, measurement can be accomplished with stable high precision and replication, and by providing a transparent cell 2 which stores a particles dispersed in a dispersion medium, and a light source which irradiates light onto the particles within the transparent cell 2, and multiple light detectors 5 scattered and arranged to detect the intensity of diffracted/scattered light produced by the irradiation of light, and a computer device 6 which calculates the particle size distribution of the particles based on the light intensity signal output from the light detectors 5, in addition to the establishment of cell storage space S which stores the transparent cell 2 and the equipment storage spaces S1 and S2 which store the light source 41a, the light detector 5, and the optical device 6, the equipment storage spaces S1 and S2 are given tight closed construction separate from the cell storage space S.
