Automatic Analyzer Detachable Interlock for Locked-Cover Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic analyzers lack maintainability due to difficult access to the interlock mechanism when the cover is locked, hindering repairs and maintenance.
Innovation Solution
An automatic analyzer with an interlock unit that includes a movable operation member, an electromagnetic driving unit, and a driving connecting unit, allowing the interlock unit to be detachable from the housing for easy access and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the interlock unit is integrated into the housing with the cover locked, then the safety and locking function is maintained, but the maintainability and accessibility for repair deteriorates
Solution Approach 1:
The interlock unit is segmented from the main housing structure and mounted separately on the front surface. This allows the interlock unit to be independently accessed, removed, and repaired without disassembling the entire housing or forcing the cover open, thus resolving the contradiction between maintaining locking reliability and enabling easy repair access.
Solution Approach 2:
The interlock unit is extracted from the internal structure and positioned on the external front surface of the housing. This extraction enables direct access to the interlock unit for maintenance purposes while the housing and cover remain intact, preserving the safety locking function during normal operation.
2Reliability
If the cover is locked to prevent opening, then the safety during operation is improved, but the accessibility for maintenance deteriorates
Solution Approach 1:
The interlock unit is separated from the cover assembly and mounted independently on the housing front surface. This segmentation allows maintenance personnel to access and service the interlock unit without needing to open or manipulate the locked cover, thus maintaining safety during operation while improving maintenance accessibility.
Solution Approach 2:
The front surface mounting position of the interlock unit serves as an intermediary access point. It is positioned on the housing front surface between the locked cover and the external environment, allowing maintenance access without compromising the cover's locking function or requiring disassembly of the safe operating configuration.
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
Facilitates improved maintainability by enabling easy access and detachment of the interlock unit, enhancing repairability and reducing downtime.
Implementation Method 1
an electromagnetic driving unit for driving the operation member; and a driving connecting unit for connecting the operation member to the electromagnetic driving unit and driving the operation member by conveying an operation of the electromagnetic driving unit to the operation member

AI summary
An automatic analyzer capable of improving maintainability by facilitating access to an interlock unit. The interlock unit includes an operation member configured to be movably supported between a lock position and a lock release position, and obstruct rotation to an open position of a cover; an electromagnetic driving unit configured to drive the operation member, and a driving connecting unit configured to connect the operation member and the electromagnetic driving unit and drive the operation member by conveying an operation of the electromagnetic driving unit to the operation member. The interlock unit is provided to be attachable and detachable to and from the housing.
