Solution Overview

Problem

Household dehumidifiers produce loud noises due to the operation of the compressor, affecting their performance and user experience.

Innovation Solution

A dehumidifier design featuring a main body with a compressor at its bottom, a lower seal panel for noise shielding positioned between the main body and the front panel, and elastic plastic parts for secure and noise-reducing assembly, where the elastic plastic parts are fixedly disposed on the lower seal panel and engage with a latching slot on the front panel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the compressor is arranged in the main body of the dehumidifier, then the device structure is simplified and integration is improved, but noise is increased and affects user experience

Engineering Contradiction:
Improvedevice structureVSAvoidcompressor noise
Core Design Contradiction:
Device complexityVSObject-generated harmful factors

Solution Approach 1:

The lower seal panel is nested within the main body structure, positioned between the front panel and compressor. This nested arrangement allows the seal panel to serve as both a structural component and a noise-blocking barrier, effectively containing compressor noise within the main body while maintaining integrated device design.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The lower seal panel acts as an intermediary element between the front panel and compressor. It provides a noise-blocking barrier that prevents direct sound transmission, while also serving as a structural support component. The elastic members further mediate by providing vibration isolation between the seal panel and front panel, reducing noise transmission to the exterior.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-generated harmful factors

If the lower seal panel is positioned between the main body and front panel, then compressor noise is blocked and electrical safety is improved, but the assembly structure becomes more complex

Engineering Contradiction:
Improvecompressor noiseVSAvoidassembly structure
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The lower seal panel combines multiple functions into a single component: noise blocking, electrical safety isolation, and structural support. By merging these functions into one integrated panel rather than using separate components, the design reduces overall assembly complexity while achieving multiple protective goals.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lower seal panel serves multiple purposes simultaneously: it blocks compressor noise from reaching the front panel, provides electrical safety isolation, and acts as a structural support element. This multi-functional design eliminates the need for separate noise barriers and safety components, simplifying the overall assembly structure.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Object-generated harmful factors

If elastic members are disposed between the lower seal panel and front panel, then noise reduction is improved through vibration isolation, but manufacturing complexity increases

Engineering Contradiction:
Improvenoise reductionVSAvoidmanufacturing complexity
Core Design Contradiction:
Object-generated harmful factorsVSEase of manufacture

Solution Approach 1:

The elastic members change the physical parameters of the connection between the seal panel and front panel by introducing flexibility and vibration isolation. This parameter change allows the rigid seal panel to be mounted on the front panel with noise-reducing elastic elements, achieving superior noise isolation without requiring complex active noise control systems.

Inventive Principle:
Principle #35Parameter changes
