Volatile Component Detection in Liquid Discharge Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing discharge apparatuses face limitations in detecting liquid discharge containing volatile compounds, as they require light to be emitted directly below the discharge ports, restricting the layout of detection units.
Innovation Solution
A discharge apparatus that detects liquid discharge by utilizing the volatilization of volatile components from the liquid, allowing detection without emitting light directly below the discharge ports, using a detection unit that captures changes in light refracted or scattered by the volatile components in the air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If light is emitted directly below the discharge ports to detect liquid discharge, then detection accuracy is improved, but the layout flexibility of detection units is restricted
Solution Approach 1:
The patent introduces a mediator substance (volatile compound or particle) that is discharged along with the liquid. This mediator allows indirect detection by scattering or emitting light, enabling the light source and detector to be positioned away from the direct discharge path while maintaining detection capability. The mediator acts as an intermediary that carries detection information from the liquid discharge to the detection unit.
Solution Approach 2:
The patent replaces direct optical detection (mechanical/optical alignment required) with indirect detection using volatile compounds or particles. Instead of requiring precise alignment between light source, discharge port, and detector, the system uses the presence of volatile compounds or particles in the discharged liquid to trigger detection through their optical properties, substituting a rigid mechanical alignment system with a more flexible chemical/biological detection approach.
2Reliability
If light is emitted directly below discharge ports, then detection reliability is improved, but device complexity increases due to restricted positioning options
Solution Approach 1:
The volatile compound or particle serves as an intermediary that enables reliable detection without requiring complex positioning. The mediator substance naturally follows the liquid discharge path and can be detected at various positions, allowing the system to maintain high reliability while simplifying the overall configuration by eliminating the need for precise alignment mechanisms.
Solution Approach 2:
The detection system is designed to be universal and multi-functional, capable of detecting different types of liquids (aqueous or non-aqueous) through their common property of containing volatile compounds or particles. This universal approach simplifies device configuration by using a single detection mechanism that works across multiple applications, rather than requiring specialized configurations for each liquid type.
