Analyzer Probe Position Adjustment With Interlocking Cover Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic analyzers require two operators for position adjustment, complicating the process and posing safety risks due to the separation between the operation controller and the actual position adjustment, as well as the need for interlocking covers that can lead to accidental contact with the analysis mechanism.
Innovation Solution
An automatic analyzer with first and second position adjustment switches and a position adjustment controller that allows for separate operation of the dispensing mechanisms, enabling single-handed adjustment and interlocking cover management to prevent accidental contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the operation controller and position adjustment location are separated, then the operator can check the position adjustment while giving the instruction, but two operators are required and the adjustment work becomes complicated
Solution Approach 1:
The patent combines the operation controller and position adjustment functionality into a single integrated unit. The operation controller includes operation switches for controlling mechanism unit positions, and the controller displays position information on its display unit. This merging eliminates the need for separate position adjustment locations and operators, allowing one operator to both control and monitor positions simultaneously.
2Ease of operation
If the interlocking cover is opened for position adjustment, then the mechanism units can be adjusted, but accidental contact with the analysis mechanism may occur creating safety risks
Solution Approach 1:
The patent implements a dynamic interlocking mechanism where the cover can be opened for position adjustment, but the analysis mechanism is automatically stopped when the cover opening is detected by a cover opening detection unit. This dynamic control allows accessibility when needed while maintaining safety through automatic mechanism stopping, preventing accidental contact during adjustment operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Simplifies the position adjustment process by allowing single-operator control and enhances safety by preventing accidental contact with the analysis mechanism during interlocking cover operations.

AI summary
Position adjustment of an analysis module in an automatic analyzer is performed where a position adjustment instruction and a position where the position adjustment is actually performed are separated from each other. Position adjustment of probe mechanisms is performed by operating probe position adjustment switches formed on a housing of an analysis module. Where interlocking covers (103 and 113) for the module are present, the probe mechanisms of the module are stopped when the closed covers are opened. The position adjustment switches (101A and 101B) and the position adjustment switch (104) are disposed to be separated from each other by a distance at which the switches cannot be operated by a single hand of an operator at the same time. Even when the cover (103) is opened by continuously pressing the position adjustment switch (104), the probe mechanisms of the module are in an operable state for the position adjustment.
