Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing evaporation and concentration mechanisms in automatic analyzers fail to adjust the evaporation amount effectively, particularly in environments with varying atmospheric pressures, such as high altitudes, leading to inconsistent evaporation rates.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If depressurization is performed in the concentration process, then evaporation and concentration of the liquid is achieved, but the evaporation amount cannot be adjusted according to atmospheric pressure variations
Solution Approach 1:
The invention introduces a dynamic adjustment mechanism by providing a variable opening degree structure in the discharge unit. The opening degree of the discharge path can be dynamically adjusted based on atmospheric pressure conditions, allowing the system to adapt evaporation rates to different environmental conditions. This resolves the contradiction by making the evaporation amount controllable rather than fixed, enabling the system to maintain optimal performance across varying atmospheric pressures.
Solution Approach 2:
The invention changes the parameter of the discharge path opening degree to control evaporation amount. By adjusting the opening degree parameter of the discharge path in response to atmospheric pressure variations, the system can modulate the evaporation rate. This parameter adjustment mechanism allows the system to compensate for environmental changes and maintain consistent concentration performance.
2Adaptability or versatility
If a complex control mechanism is introduced to adjust evaporation amount, then adaptability to different environments is improved, but device complexity increases
Solution Approach 1:
The discharge unit is designed with multi-functionality, serving both as a simple discharge path and as an adjustable control mechanism. The variable opening degree structure allows the same component to function in different modes (fully open, partially open, closed) depending on atmospheric pressure conditions, eliminating the need for separate complex control mechanisms while maintaining environmental adaptability.
Solution Approach 2:
The system is designed to automatically respond to atmospheric pressure variations through the adjustable opening degree mechanism, without requiring external complex control systems. The mechanism self-adjusts based on environmental conditions, reducing the need for additional sensors, controllers, and actuators that would increase device complexity.
