Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a glove box with high airtightness is used to reduce residual water content, then the analysis environment quality is improved, but the cost and device complexity increase significantly
Solution Approach 1:
The system divides the airtight space into two independent sections: a sample preparation section that can be opened to the atmosphere, and an analysis section that maintains controlled atmosphere. This segmentation allows standard analytical instruments to be used without requiring a complete glove box system.
Solution Approach 2:
A transfer mechanism acts as an intermediary between the atmospheric preparation area and the controlled analysis area. This intermediary enables sample transfer while maintaining atmospheric separation, allowing standard devices to function without direct connection to a glove box.
2Reliability
If a glove box with high airtightness is used to reduce residual water content, then the analysis environment quality is improved, but the running cost increases
Solution Approach 1:
By segmenting the airtight space into preparation and analysis sections, the system eliminates the need for continuous purge gas supply throughout the entire system. Only the analysis section requires atmosphere control, significantly reducing running costs while maintaining analysis quality.
3Ease of operation
If standard devices are used without glove box connection, then the ease of operation is improved, but the residual water content control deteriorates
Solution Approach 1:
The preparation section is designed to be accessible to the atmosphere for easy sample handling, while the analysis section maintains controlled atmosphere through sealing. This segmentation enables standard devices to be operated easily while still achieving low residual water content in the analysis area.
Solution Approach 2:
Atmosphere control is applied locally only to the analysis section where it is critically needed, rather than throughout the entire system. This local quality approach maintains measurement precision while simplifying sample preparation operations.
4Reliability
If the airtight section is modified to connect to a glove box, then the residual water content control is improved, but the device complexity and modification requirements increase
Solution Approach 1:
The system provides a modular airtight section that can function independently without glove box connection. This segmentation eliminates the need for complex modifications to connect standard devices to glove boxes, simplifying manufacturing while maintaining atmosphere control capability.

AI summary
An analysis system and an analysis method, capable of setting a sample in an atmosphere where the residual water content is reduced, without using a glove box with high airtightness. An analysis system 100 according to this disclosure includes: a sample holding section 10 that holds a sample to be analyzed; an airtight section 20 that has an opening portion (lower opening 23a) to internally house the sample holding section 10 through the opening portion; and a surrounding section 30 having flexibility and visible light permeability that separates the sample holding section 10 and the opening portion of the airtight section 20 from the outside. The airtight section 20 can transition in state between a housing state where the airtight section 20 internally houses the sample holding section 10 and airtightly closes the opening portion with respect to the inside of the surrounding section 30 and a non-housing state where the sample holding section 10 is located outside the airtight section 20. When at least the airtight section 20 is in the non-housing state, a cooling section is arranged inside the surrounding section 30 but outside the airtight section 20.
