Solution Overview

Problem

Existing clothes dryers lack an efficient mechanism for separating and cleaning the lint removal apparatus, leading to reduced drying performance due to lint accumulation.

Innovation Solution

A clothes dryer with a lint removal apparatus that includes a coupler structure with a first and second coupler, an elastic member, and a link member, allowing for easy separation and cleaning by rotating a front cover and using a holder and link member to decouple the components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the lint removal apparatus is made separable for easy cleaning, then the ease of operation is improved, but the device complexity increases due to additional coupling and separation mechanisms

Engineering Contradiction:
Improveease of cleaningVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The lint removal apparatus is divided into separable components including a filter assembly, lint box, and coupling mechanisms. The filter can be detached from the lint box, and the lint box can be separated from the dryer body, enabling easy cleaning and maintenance without disassembling the entire dryer.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A coupling mechanism serves as an intermediary between the lint box and the dryer body, allowing for easy connection and separation. The coupling device includes coupling protrusions and recesses that facilitate quick attachment and detachment while maintaining structural integrity during operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the filter is provided to be directly removed by users, then the ease of operation is improved, but lint may accumulate and drying performance deteriorates if not cleaned regularly

Engineering Contradiction:
Improvefilter removalVSAvoiddrying performance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system enables users to easily remove and clean the filter themselves without requiring professional service. The filter is designed with simple attachment and detachment mechanisms that allow users to access, clean, and reinstall the filter regularly to maintain optimal drying performance.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The design anticipates user cleaning needs by providing easy access to the filter and lint box before lint accumulation becomes problematic. The separable structure allows users to perform maintenance proactively, preventing performance degradation rather than addressing it after problems arise.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If a separate filter cleaning module is added to the dryer, then the ease of operation is improved, but the device complexity and manufacturing cost increase

Engineering Contradiction:
Improvefilter cleaningVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

Instead of integrating a complex automated cleaning module into the dryer, the solution extracts the cleaning function to be performed manually by users. The filter and lint box are designed to be easily removable and cleanable outside the dryer, eliminating the need for additional motors, sensors, and control systems while maintaining effective lint removal.

Inventive Principle:
Principle #2Taking out (Extraction)
