Humidifier Disc Assembly for Direction-Free Stacking Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional disc assemblies in evaporative humidifiers are inconvenient to assemble due to directional requirements, making the assembly process cumbersome.
Innovation Solution
The design incorporates a disc assembly with a ring-shaped disc member divided into sectors by assembly parts, featuring alternately formed protrusion parts on opposite surfaces, allowing for easy stacking and alignment without considering directionality, facilitated by plate members that secure the discs together.

1Reliability
If conventional disc assemblies are designed with directional requirements for assembly, then the structural stability and functional performance are improved, but the assembly convenience and operational ease deteriorate
Solution Approach 1:
The disc assembly utilizes asymmetric protrusion parts positioned at specific locations on each disc. These protrusions are designed to fit into corresponding recesses only in one orientation, ensuring proper alignment and structural stability while guiding the assembly process. The asymmetric design inherently provides directional guidance during assembly, making the assembly process simpler despite the directional requirements.
Solution Approach 2:
The disc assembly design incorporates self-aligning features where protrusion parts on one disc automatically fit into recesses of adjacent discs during the stacking process. This self-service mechanism guides the discs into the correct orientation without requiring external alignment tools or complex assembly procedures, thereby maintaining both structural stability and assembly convenience.
2Productivity
If multiple discs are stacked to form the disc assembly, then the humidifying performance is improved, but the assembly complexity increases due to directional considerations
Solution Approach 1:
The disc assembly is segmented into multiple identical or similar disc units, each equipped with protrusion parts at standardized positions. This segmentation allows for modular stacking where each disc performs the same humidifying function. The repetitive structure simplifies manufacturing and assembly, as workers only need to stack identical components without complex directional considerations beyond the simple protrusion-recess alignment.
Solution Approach 2:
Multiple disc units are merged together through the stacking process, with protrusion parts of one disc fitting into recesses of the next disc. This merging creates a unified disc assembly that maintains the rotational integrity and functional performance required for effective humidification, while the simple interlocking mechanism keeps the assembly process straightforward.
