Inclined Sample Container Holder With Rotation Stopper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mass spectrometers, when multiple sample containers are installed in an inclined state to optimize space and maintainability, they are prone to rotation around the hook member, leading to potential lid removal and sample leakage, causing contamination and scattering issues.
Innovation Solution
A sample container holding mechanism featuring a hook member and stopper members that suspend and restrict the rotation of the sample container, with vertically disposed stopper members to guide and drain any leaked samples, preventing contamination and fixing connected pipes to prevent unintended flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sample container is installed in an inclined state by suspending with a hook member, then space utilization and maintainability are improved, but the sample container becomes prone to rotation around the hook member
Solution Approach 1:
The stopper member is pre-positioned on the hook member to prevent rotation before it can occur. This preliminary constraint ensures the sample container remains stable in its inclined position while still allowing installation and maintenance operations to be performed.
Solution Approach 2:
The stopper member acts as an intermediary element between the hook member and the sample container. It mediates the connection by providing a stopping surface that prevents rotation while allowing the container to hang in the desired inclined position.
2Ease of repair
If the sample container is suspended in an inclined state, then maintainability is improved, but the lid member may come off and sample may leap out due to rotation
Solution Approach 1:
The stopper member is installed in advance to prevent rotation before it can cause the lid to come off or sample to leak. This preliminary protective measure ensures containment reliability is maintained while preserving ease of maintenance.
Solution Approach 2:
The stopper member provides preliminary anti-action against the rotational force that would otherwise cause the lid to detach and sample to leap out. By counteracting this harmful rotation in advance, the system maintains both reliability and maintainability.
3Stability of the object's composition
If a stopper member is added to restrict rotation, then rotational stability is improved, but device complexity increases
Solution Approach 1:
The holding mechanism is segmented into distinct functional elements: the hook member for suspension and the stopper member for rotation prevention. This segmentation allows each component to be simple in itself while collectively providing the required stability without excessive complexity.
Solution Approach 2:
The stopper member provides localized constraint only where needed - at the point where rotation would occur around the hook member. This local quality approach prevents unnecessary complexity by applying constraint only in the specific location required for stability.

Function Achieved in This Case
Effectively restricts sample container rotation, prevents lid removal and sample leakage, and ensures containment of leaked samples, reducing contamination risks and manufacturing costs by integrating the stopper members for dual functionality.
Implementation Method 1
The stopper member restricts the rotation of the sample container when the sample container is rotated around the hook member
Implementation Method 2
a first inclined surface that guides the sample received by the first receiving surface to a direction away from the first receiving surface
Implementation Method 3
a second inclined surface that receives and guides the sample that has fallen from the first drain port to the second receiving surface side

AI summary
A sample container holding mechanism is for holding a sample container 6, and includes a hook member 9 and a stopper member 10. The hook member 9 suspends and holds the sample container 6 in a state where the sample container 6 is inclined with respect to a vertical direction. The stopper member 10 restricts the rotation of the sample container 6 when the sample container 6 is rotated around the hook member 9.
