Sample Heating Device Cover Sliding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sample heating devices require manual operation for mounting and unmounting sample boats, necessitating additional mechanisms for opening and closing the mounting port cover, which complicates the system and lacks automation.
Innovation Solution
A cover sliding mechanism using a guide rail inclined relative to the vertical direction, combined with a roller and an opening/closing cover pushing portion, allows the sample boat conveying portion to move the cover horizontally by utilizing its upward and downward movements, eliminating the need for a dedicated drive mechanism for the cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual operation is used for mounting and unmounting sample boats, then the device structure remains simple, but automation is lost and additional mechanisms are required for cover operation
Solution Approach 1:
The patent combines the cover opening/closing function with the sample boat conveying motion. The guide rail is integrated into the conveying mechanism, and the roller on the conveying portion engages with the guide rail to simultaneously achieve both cover movement and sample boat transport, eliminating the need for a separate cover drive mechanism
Solution Approach 2:
The sample boat conveying portion is designed to perform multiple functions: it conveys the sample boat horizontally and simultaneously operates the cover opening/closing mechanism through its engagement with the inclined guide rail. This multi-functional design reduces overall system complexity while achieving automation
2Extent of automation
If a dedicated drive mechanism is added for the cover, then automation is achieved, but the device structure becomes more complex
Solution Approach 1:
The patent merges the cover drive function into the existing sample boat conveying mechanism. The inclined guide rail and roller combination allows the conveying motion itself to drive the cover, eliminating the need for a dedicated cover motor or actuator
Solution Approach 2:
The system uses its own conveying motion to automatically operate the cover. The sample boat conveying portion, while performing its primary function of transporting the sample boat, automatically opens and closes the cover through its engagement with the inclined guide rail, making the system self-sufficient
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
This solution simplifies the device structure by automating the opening and closing of the mounting port cover, reducing the complexity and cost of the system while enabling efficient horizontal movement of the cover, thus enhancing operational efficiency.
Implementation Method 1
a guide rail that is attached to the opening/closing cover and inclined with respect to the vertical direction as a structure to be engaged with the part of the sample boat conveying portion, the part of the sample boat conveying portion being engaged with the guide rail and sliding along the guide rail when the sample boat conveying portion moves up and down to thereby move the opening/closing cover in the horizontal direction
Implementation Method 2
A roller that can rotate in a vertical plane is preferably provided to the part of the sample boat conveying portion to be engaged with the guide rail. In this way, the part of the sample boat conveying portion smoothly slides along the guide rail
Implementation Method 3
an opening/closing cover pushing portion that moves up and down with the sample boat conveying portion and pushes the opening/closing cover from above in synchronization with the downward movement of the sample boat conveying portion so that the opening/closing cover coming to the position above the opening of the mounting port to seal the opening

AI summary
A sample heating device includes: an opening/closing cover provided to be movable in a horizontal direction between a position above an opening of a mounting port and a position displaced from the position above the opening, and a cover sliding mechanism that is engaged with a part of a sample boat conveying portion when the sample boat conveying portion comes to a predetermined position in a horizontal plane and moves the opening/closing cover in the horizontal direction according to upward and downward movements of the sample boat conveying portion so that the opening/closing cover is provided at the position directly above the opening of the mounting port when the sample boat conveying portion comes to a predetermined height.
