Atomization Unit Electrode Insulation for Conduction Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The reliability of conduction between pin electrodes and planar electrodes in non-combustion suction devices is not adequately secured, leading to potential short circuits and inconsistent performance.
Innovation Solution
The design incorporates a configuration where pin electrodes are positioned to avoid direct contact with multiple planar electrodes, with a wider insulation area and semicircular planar electrodes to absorb dimensional variations, along with a restriction portion to prevent rotation and ensure stable contact, and a tapered restriction portion for easy alignment and attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pin electrodes are positioned closer to planar electrodes to improve conduction reliability, then electrical connection stability improves, but risk of short circuit between multiple planar electrodes increases
Solution Approach 1:
An insulation portion is introduced as an intermediary element between the pin electrodes and planar electrodes. This insulation portion prevents direct contact between multiple planar electrodes while still allowing the pin electrode to maintain reliable electrical connection with the planar electrode through controlled contact points.
Solution Approach 2:
The insulation portion is strategically positioned only in specific locations where short circuit risk exists, rather than providing uniform insulation everywhere. This localized insulation approach maintains good electrical contact where needed while preventing short circuits only where necessary.
2Object-affected harmful factors
If insulation portion width is increased to prevent short circuits, then short circuit prevention improves, but dimensional variation absorption capability decreases
Solution Approach 1:
The insulation portion width is optimized to provide just enough insulation to prevent short circuits while leaving sufficient space for dimensional variations. The insulation is positioned strategically rather than uniformly, allowing the planar electrodes to accommodate manufacturing tolerances while still being protected from short circuits.
3Reliability
If restriction portion is added to prevent rotation, then connection stability improves, but device complexity increases
Solution Approach 1:
The restriction portion is integrated into the existing electrode assembly structure rather than being added as a separate component. This merging approach prevents rotation and improves connection stability while minimizing the increase in device complexity by using the same structural elements for multiple functions.
