Automated Analyzer Overflow Outlet Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated analyzers require additional components and increased complexity for liquid reservoir overflow systems, leading to potential operational issues and increased maintenance labor without a corresponding reduction in component count.
Innovation Solution
The automated analyzer incorporates a liquid reservoir design where the overflow outlet is positioned on the inner side of the drain flow path, preventing liquid leakage and allowing for efficient liquid replacement without adding new components, and includes a pan to catch any leaks, thereby reducing operational complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a cleaning liquid discharge port is provided directly below a flow path outlet of an overflow portion, then liquid can be discharged efficiently, but it requires newly preparing a flow path member of a cleaning liquid supply system which increases device complexity
Solution Approach 1:
The patent combines the cleaning liquid discharge function with the existing overflow portion structure. The cleaning liquid discharge port is integrated into the overflow portion rather than being a separate component, thereby merging multiple functions into a single structure and avoiding the need for additional flow path members.
Solution Approach 2:
The overflow portion is designed to serve multiple functions: it allows excess liquid to overflow and also provides the discharge port for cleaning liquid. This multi-functional design eliminates the need for dedicated separate components for each function, reducing overall device complexity.
2Ease of operation
If a liquid reservoir is provided with a discharge flow path, then liquid can be discharged directly, but it requires newly preparing a flow path member of a discharge system which increases device complexity
Solution Approach 1:
The discharge flow path is merged with the existing overflow portion structure. Rather than creating a completely separate discharge system, the patent utilizes the overflow portion as the discharge pathway, thereby combining functions and reducing the number of distinct flow path members.
Solution Approach 2:
The liquid reservoir utilizes its own overflow structure to provide discharge capability, rather than requiring an external separate discharge system. The system serves itself by using the existing structural features for multiple purposes.
3Adaptability or versatility
If additional flow path members are added to the analyzer, then liquid management functionality is enhanced, but it causes an increase in the number of components leading to increased device complexity and size
Solution Approach 1:
The overflow portion is designed to perform multiple functions including liquid overflow, cleaning liquid discharge, and potentially other liquid management tasks. This universal design allows enhanced liquid management functionality without proportionally increasing the number of components.
Solution Approach 2:
Multiple liquid management functions are merged into the existing overflow portion structure rather than being implemented through separate dedicated components. This approach enhances functionality while maintaining a compact component count.

AI summary
[Object] Provided are an automated analyzer for analyzing a substance contained in an unknown sample and a liquid reservoir, the analyzer and the reservoir being capable of saving users' operation without remarkably increasing the number of components. [Solution] A flow path outlet 502a of an overflow portion 502 of liquid reservoirs 404 and 405 projects closer to the inner circumferential side of a drain flow path 264 than to an inner circumferential surface 264a1 side of an outer wall 264a of the drain flow path 264 serving as a destination to which liquid overflows. In addition, the flow path outlet 502a projects so as to come into contact with an outer wall 260a of the inner pipe 260. The flow path outlet 502a of the overflow portion 502 projects into the drain flow path 264 so as to be located below an upper end 264a2 of the outer wall 264a of the drain flow path 264.
