Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic sample injection devices have fixed solvent arrangements and methods, limiting user flexibility in customizing cleaning operations to enhance contamination suppression or reduce solvent consumption.
Innovation Solution
The device includes a solvent arrangement unit, a method setting unit, a solvent arrangement setting unit, and a control unit, allowing users to arbitrarily set the method of cleaning operations and the number/types of solvents, enabling customized solvent arrangements suitable for the set method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the types and number of solvents are fixed in the device, then the device structure is simple, but the user cannot arbitrarily set the cleaning operation method
Solution Approach 1:
The solvent arrangement unit is designed to be dynamically reconfigurable, allowing the number and types of solvents to be changed based on user-defined cleaning methods. The system transitions from a fixed solvent configuration to a dynamic one where solvent arrangements can be adjusted to match different cleaning operation requirements, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The system allows users to define cleaning operation methods with specific parameters (number of cleaning steps, solvent types, sequence), and the solvent arrangement unit automatically adjusts its configuration to match these parameters. This parameter-driven approach enables arbitrary setting of cleaning methods while maintaining systematic control over the solvent arrangement.
2Object-affected harmful factors
If the cleaning operation method is changed to enhance contamination suppression, then the contamination suppression effect is improved, but solvent waste occurs
Solution Approach 1:
The system enables optimization of cleaning operation parameters (number of cleaning steps, solvent types, sequence) to achieve the minimum effective cleaning that suppresses contamination. By allowing arbitrary setting of these parameters, users can find the optimal balance between contamination suppression and solvent consumption, avoiding both excessive solvent use and insufficient cleaning.
Solution Approach 2:
The system allows users to independently optimize their cleaning protocols based on their specific needs and observations, enabling them to adjust the cleaning method to achieve effective contamination suppression with minimal solvent waste, rather than being forced to use fixed, potentially excessive cleaning protocols.
3Loss of substance
If the cleaning operation method is changed to save solvent consumption, then the solvent consumption is reduced, but the contamination suppression effect is weakened
Solution Approach 1:
The system allows users to carefully adjust cleaning parameters (reducing number of steps, changing solvent types) to minimize solvent consumption while maintaining adequate contamination suppression. The flexibility to arbitrarily set methods enables users to find the minimum effective cleaning protocol that still protects against contamination.
Solution Approach 2:
The system enables users to apply only the necessary degree of cleaning action required to suppress contamination, avoiding excessive cleaning steps. By allowing arbitrary method setting, users can determine the minimum effective cleaning protocol that achieves adequate contamination suppression with reduced solvent consumption.
