Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional analysis devices face a trade-off between measurement resolution and circuit scale, where improving measurement resolution in the rotating direction of a specimen analysis disc increases the circuit scale, and existing methods indirectly measure nanoparticle distribution, which may not accurately represent the reaction region.
Innovation Solution
The analysis device employs a method to shift gate signals in the rotating direction of the specimen analysis disc, dividing the reaction region into multiple sub-regions with adjusted gate widths and shift amounts, allowing for precise measurement of nanoparticle distribution without increasing circuit complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the gate width of the gate signal is decreased to improve measurement resolution, then the measurement resolution in the rotating direction is improved, but the number of gate signals generated increases resulting in an increase in circuit scale
Solution Approach 1:
The reaction region is divided into multiple divided regions in the rotating direction, with each region associated with a specific gate signal. By shifting gate signals in the rotating direction and assigning them to specific divided regions, the system achieves fine measurement resolution without requiring a proportional increase in the total number of gate signals, thus avoiding circuit scale expansion.
Solution Approach 2:
The patent introduces a spatial dimension (rotating direction) for gate signal arrangement by shifting gate signals to different angular positions. This dimensional approach allows multiple gate signals to share the same radial track while being differentiated by their angular positions, improving measurement resolution without increasing circuit complexity.
2Ease of manufacture
If conventional indirect measurement methods are used to count nanoparticles per gate signal, then the measurement process is simplified, but the accuracy of nanoparticle distribution representation in the reaction region is reduced
Solution Approach 1:
The reaction region is segmented into multiple divided regions, each monitored by a specific gate signal. This segmentation allows the system to capture spatial distribution information of nanoparticles across different regions while maintaining the simplicity of counting-based measurement methods. The divided regions provide a structured framework that preserves measurement simplicity while enhancing distribution accuracy.
Solution Approach 2:
The patent creates a virtual representation of the reaction region by mapping nanoparticle counts from multiple divided regions to their corresponding spatial positions. This copying approach reconstructs the nanoparticle distribution pattern without requiring complex direct imaging, thus maintaining measurement simplicity while improving distribution representation accuracy.

AI summary
An analysis device includes an optical disc drive, a gate information processing unit, a detection circuit, and a gate shift processing unit. The optical disc drive rotates a specimen analysis disc and detects a measurement radial position for an optical pickup. The detection circuit generates gate signals shifted by a gate shift amount in each measurement radial position in a rotating direction of the specimen analysis disc, and generates count values of the respective gate signals. The gate shift processing unit divides a gate signal-corresponding region of the corresponding gate signal by a unit gate shift amount in the rotating direction of the specimen analysis disc to define a plurality of divided regions, and sets count values of the divided regions based on the count values of the gate signals.
