Atomization Module Adhesive Groove Structure Against Vibration Peeling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The bonding surfaces between the atomization component and the support member in nebulizers are prone to peeling off due to long-term vibration, leading to gaps and moisture permeation, which can cause short circuits between the positive and negative electrodes of the piezoelectric component, reducing the service life of the atomization component.
Innovation Solution
An atomization module design featuring a main fixing member, auxiliary fixing member, and piezoelectric component, with adhesive grooves and adhesive filling to enhance bonding strength and prevent moisture ingress, thereby stabilizing the structure and preventing short circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the atomization component is bonded to the support member using conventional bonding methods, then the assembly is simple to manufacture, but the bonding surface is easily peeled off under long-term vibration, resulting in gaps and moisture permeation
Solution Approach 1:
The support member is divided into a main body and a protruding portion that extends into the adhesive groove, creating a mechanical interlocking structure. This segmentation allows the bonding interface to be divided into multiple contact areas, preventing peeling under vibration while maintaining manufacturing simplicity.
Solution Approach 2:
The protruding portion of the support member is nested within the adhesive groove, creating a nested structural relationship. This nested design provides mechanical reinforcement to the bonding interface, preventing peeling without requiring additional external components or complex assembly procedures.
2Reliability
If gaps form at the bonding interface due to peeling, then moisture can penetrate into the atomization component, but the bonding structure itself remains simple
Solution Approach 1:
The adhesive groove and protruding portion are pre-formed during manufacturing, creating a built-in moisture barrier structure before assembly. This preliminary action ensures that even if peeling occurs, the adhesive material remains contained within the groove structure, preventing moisture penetration without requiring additional protective components.
Solution Approach 2:
The adhesive material acts as an intermediary substance that is contained within the adhesive groove structure. This intermediary design allows the adhesive to maintain its bonding function while being protected from displacement, thereby preventing moisture pathways without requiring separate sealing components.
3Duration of action of moving object
If the atomization component vibrates continuously, then atomization function is maintained, but the bonding surface peels off due to long-term vibration
Solution Approach 1:
The adhesive groove structure provides beforehand cushioning by creating a mechanical interlock that absorbs and distributes vibration stresses. The protruding portion acts as a stress-dissipating feature that prevents crack propagation at the bonding interface, thereby extending service life under continuous vibration conditions.
Solution Approach 2:
The adhesive material forms a flexible bonding layer within the groove structure that can accommodate vibration-induced deformations. This flexible bonding interface maintains adhesion under dynamic vibration conditions, preventing peeling and extending the operational life of the atomization component.
