Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measuring instruments for analyzing particle quality in industrial productions, such as seed quality, face challenges in accurately separating particles before analysis, leading to inaccuracies in computer-based methods due to overlapping particles.
Innovation Solution
A measuring instrument with dosing chutes and vibration generators, where a camera and light source are placed above the chutes to monitor particle density and control vibration intensity, ensuring particles are separated before entering the analysis area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If particles are conveyed through dosing chutes to the analysis area, then particle quality analysis can be performed, but particles may overlap leading to inaccurate analysis
Solution Approach 1:
The patent applies vibration to the dosing chutes to control particle flow and separation. By mechanically vibrating the chutes, particles are separated into individual units as they fall through the analysis area, preventing overlap and ensuring accurate imaging and analysis of each particle's quality parameters.
2Measurement precision
If light sources and cameras are placed below dosing chutes, then particle density can be measured, but the flow of particles cannot be monitored
Solution Approach 1:
The patent positions the camera above the dosing chutes instead of below, changing the observation dimension. This overhead positioning allows the camera to capture both the particle density on the chutes and the flow of particles as they move through the analysis area, providing comprehensive monitoring capability in a single viewpoint.
3Manufacturing precision
If vibration intensity is increased to separate particles, then particle separation improves, but control precision becomes more difficult
Solution Approach 1:
The patent implements a feedback control system where the camera continuously monitors particle density and flow on the dosing chutes. This visual information is fed back to control the vibration intensity, allowing precise adjustment of vibration levels to achieve optimal particle separation while maintaining accurate control through real-time observation and adjustment.
