Sample Introduction Device Tube Heating Movement Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sample introduction devices require complex structures and increased manufacturing costs due to the need for separate mechanisms to move the tube heating unit, complicating the design and prolonging the cooling time of the sample tube.
Innovation Solution
A sample introduction device with a movement mechanism that allows the tube holding unit and tube heating unit to be separately moved using a common connecting member, such as a magnetically attachable nut, which simplifies the configuration and enables independent movement of these units along a straight line, allowing for efficient cooling of the sample tube by separating the heating unit during the cooling process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a separate mechanism is added to move the tube heating unit independently, then the cooling time of the sample tube is reduced, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the movement functions of the tube holding unit and tube heating unit into a single integrated movement mechanism. The connecting member serves as a common attachment point for both units, allowing them to be moved together or separately using the same mechanical structure, thereby reducing device complexity while enabling independent positioning for cooling operations
Solution Approach 2:
The connecting member is designed with universal functionality to attach to both the tube holding unit and tube heating unit. This multi-functional component allows a single movement mechanism to perform multiple operations: moving the tube holding unit to pressing/sampling positions, moving the tube heating unit to heating positions, and enabling independent separation for cooling, thus avoiding the need for separate dedicated mechanisms
2Loss of time
If a separate mechanism is added to move the tube heating unit independently, then the cooling efficiency is improved, but the manufacturing cost increases
Solution Approach 1:
The patent merges the movement mechanisms for the tube holding unit and tube heating unit into a single integrated system. By using a common connecting member and shared mechanical components (support shaft, nut, motor), the manufacturing cost is reduced compared to implementing two completely separate movement mechanisms, while still enabling independent positioning for efficient cooling
3Device complexity
If the tube holding unit and tube heating unit are moved using a common mechanism, then the device structure is simplified, but the ability to separately position them is reduced
Solution Approach 1:
The patent implements dynamic positioning capability where the tube holding unit and tube heating unit can be independently attached or detached from the connecting member during operation. This dynamic reconfiguration allows the system to adapt between different operational modes (joint movement for sampling, separate positioning for heating and cooling) while using a single simplified movement mechanism

AI summary
A sample introduction device includes a tube holding unit 10, a tube heating unit 20, and a movement mechanism 30. The tube holding unit 10 holds a sample tube 1. The tube heating unit 20 comes into contact with the sample tube 1 held in the tube holding unit 10 and heats the sample tube 1 to desorb sample components in the sample tube 1. The tube holding unit 10 and the tube heating unit 20 are attached to the movement mechanism 30 so as to be able to move separately. The movement mechanism 30 includes a nut 32 which can be attached to and detached from the tube holding unit 10 and the tube heating unit 20, and a support shaft 31 which supports the nut 32 such that the nut 32 can move.
