Rotating Hole Members for Portable Analyzer Cleaning Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable analyzers face challenges in easy and proper cleaning of the interior hole when stained, leading to impaired analysis due to specimen adherence and lack of effective cleaning mechanisms, which complicates maintenance and increases the risk of hygiene issues.
Innovation Solution
A portable analyzer design featuring rotating first and second members that switch between a closed and flared open state, allowing for easy access and cleaning of internal components without disassembly, including slide guide and auxiliary guide mechanisms to facilitate this process and a locking mechanism to maintain the correct positional relation, along with a determination system for proper alignment and an alarm for notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the portable analyzer uses a fixed hole structure for sampling implement insertion, then the device maintains structural simplicity and compactness, but the interior of the hole becomes difficult to clean when stained
Solution Approach 1:
The patent applies the dynamics principle by making the first and second members rotatable relative to each other, transforming the static hole structure into a dynamic one. When the members rotate to a separated position, the hole opens up allowing easy access for cleaning the internal surfaces, while maintaining structural simplicity when closed
Solution Approach 2:
The patent divides the hole-forming structure into two separate members (first member and second member) that can move independently. This segmentation allows the internal surfaces of the hole to be exposed for cleaning by rotating the members apart, while maintaining a unified compact structure during normal operation
2Ease of repair
If the portable analyzer allows easy cleaning access, then maintenance becomes simpler, but the device structure becomes more complex
Solution Approach 1:
The rotatable mechanism allows the device to transition between a compact closed state and an open cleaning state. The same dynamic structure that enables cleaning access does not require separate disassembly mechanisms, thus adding minimal structural complexity while greatly improving maintenance ease
Solution Approach 2:
The rotatable members serve dual functions: forming the sampling hole during analysis operation and enabling cleaning access during maintenance. This multi-functionality eliminates the need for separate cleaning mechanisms, maintaining structural simplicity while improving maintenance ease
3Ease of operation
If the first and second members can rotate freely, then cleaning access is improved, but the positional relation between members may become incorrect
Solution Approach 1:
The determination means detects whether the first and second members are in the correct positional relation after rotation. This feedback mechanism ensures that even after free rotation for cleaning, the members return to and maintain the precise alignment required for accurate specimen analysis
Solution Approach 2:
The locking mechanism is designed to automatically engage when the members return to the correct positional relation. This preliminary action of locking prevents subsequent displacement, ensuring positional precision is maintained without requiring continuous active control

AI summary
A portable analyzer A1 includes: hole forming means designed to form a hole 3 for insertion of a specimen sampling implement 6 therein; and analyzing means capable of analyzing a specimen when the sampling implement 6 is inserted into the hole 3, the hole forming means including a first member 1 having a first region R1 corresponding to a portion of an internal surface of the hole 3, and a second member 2 having a second region R2 corresponding to another portion of the internal surface of the hole 3. The first and second members 1 and 2 are capable of relative movement while being coupled to each other, the relative movement causing at least one of the first and second regions R1 and R2 to be exposed to outside for easy cleaning thereof.
