Ion Analyzer Electrode Mounting for Reproducible Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ion analyzers face challenges in easily attaching and detaching electrodes with high position reproducibility, particularly in narrow spaces, due to the lack of a specific method for fixing these electrodes in the ionization chamber.
Innovation Solution
The ion analyzer employs a first member with a fixing pin and pin hole, a second member with concave parts for engaging with the fixing pin and insertion pin, and a pin member to securely attach and detach electrodes by sliding and fixing the second member, ensuring high position reproducibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electrodes are fixed in the ionization chamber using conventional methods, then the ion intake efficiency is maintained, but the attachment and detachment operations become complex and time-consuming in narrow spaces
Solution Approach 1:
The electrode fixing mechanism is segmented into separate functional components: a fixing member with positioning protrusions, an electrode member with corresponding positioning grooves, and a fastening component. This segmentation allows each part to perform its specific function independently, enabling quick attachment and detachment without complex integrated structures.
Solution Approach 2:
Positioning protrusions and positioning grooves serve as intermediary elements that mediate between the fixing member and electrode member. These intermediaries provide automatic alignment and positioning during attachment, eliminating the need for complex adjustment operations and reducing attachment time.
2Loss of time
If electrodes are easily attachable and detachable, then the operation time is reduced, but the position reproducibility between attachments deteriorates
Solution Approach 1:
The positioning protrusions and grooves are designed to automatically align the electrode member with the fixing member during attachment. This self-aligning mechanism ensures consistent positioning without requiring manual adjustment or complex fixing structures, achieving both quick attachment and high position reproducibility.
Solution Approach 2:
The invention replaces complex mechanical adjustment systems with a simple geometric fitting system based on positioning protrusions and grooves. This substitution maintains position reproducibility through precise geometric relationships rather than mechanical adjustment mechanisms, enabling quick attachment while ensuring consistent positioning.
3Adaptability or versatility
If multiple electrodes are disposed in the ionization chamber, then the ion control capability is improved, but the device complexity increases
Solution Approach 1:
The fixing member is designed as a universal component that can accommodate multiple different electrode members through standardized positioning protrusions and grooves. Each electrode member can be independently attached and detached using the same fixing mechanism, reducing overall system complexity while maintaining the ability to control multiple ion beams.
