Solution Overview

Problem

Conventional humidifiers have complex structures that make them difficult to disassemble, clean, and maintain, leading to hygiene issues and inaccurate water level detection due to integrated weight measurement sensors that are prone to malfunction and damage.

Innovation Solution

A humidifier design with a separable flow path structure, where the inner shell and water tank are detachable, allowing for easy cleaning and maintenance, and a load sensor system that separates the water tank from the weight measurement sensors to improve accuracy and durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the humidifier uses an integrated structure with multiple parts assembled inside the case, then the device can be compact, but it becomes difficult to disassemble and clean

Engineering Contradiction:
Improvecase volumeVSAvoiddisassembly ease
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The humidifier is divided into distinct modules: a water tank module that can be detached from the case, and a separate flow path structure. The water tank module includes the water tank and associated components, allowing users to easily remove and clean the water storage area without disassembling the entire device. This segmentation maintains compact overall volume while enabling easy maintenance.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If weight measurement sensors are integrated into the housing to detect water level, then the structure is simplified, but the sensors become prone to malfunction and damage from water exposure

Engineering Contradiction:
Improvestructure complexityVSAvoidsensor reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The weight measurement sensors are extracted from the housing and relocated to the water tank module. This allows the sensors to remain integrated with the water level detection function while being protected from water damage through proper sealing in the removable tank module. The sensors can accurately measure water weight without being exposed to the humid environment inside the main housing.

Inventive Principle:
Principle #2Taking out (Extraction)

3Volume of moving object

If multiple parts are assembled in a complex structure, then the humidifier can be compact, but users find it difficult to reassemble parts after disassembly

Engineering Contradiction:
Improvecase volumeVSAvoidreassembly ease
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The device is segmented into clearly defined modules with standardized connection interfaces. The water tank module attaches to the case through simple mechanical coupling mechanisms that provide tactile feedback and visual alignment guides. This modular design with clear interfaces enables users to easily reassemble the components in the correct configuration without requiring complex alignment procedures.

Inventive Principle:
Principle #1Segmentation
