Solution Overview

Problem

Existing clothing dryers have fiber lint removal parts and collection containers arranged at scattered positions, occupying large space and affecting the overall layout and user experience.

Innovation Solution

A clothing drying apparatus with an annular filter member connected to the drying drum, a lint cleaning member, and a lint collecting member, where the lint cleaning member and collecting member are integrated on an installation member, optimizing the layout by centralizing the components and improving user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the fiber lint removal part and collection container are arranged at scattered positions on the clothing dryer, then the lint can be effectively removed and collected, but the overall layout is affected and the structure becomes not concise

Engineering Contradiction:
Improvelint removal effectivenessVSAvoidoverall structure layout
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines the fiber lint removal part and the collection container into an integrated assembly where the removal part is positioned at the drum outlet and the collection container is directly connected beneath it. This merging of previously scattered components into a unified structure achieves effective lint removal while maintaining a concise overall layout, directly resolving the technical contradiction between removal effectiveness and structural complexity

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If the fiber lint removal part and collection container are arranged at scattered positions, then lint collection is achieved, but they occupy a large space

Engineering Contradiction:
Improvelint collection capabilityVSAvoidspace occupation
Core Design Contradiction:
Ease of manufactureVSVolume of moving object

Solution Approach 1:

The patent implements a nested arrangement where the collection container is positioned directly beneath the fiber lint removal part, with the removal part extending into the container's space. This nesting of components vertically rather than horizontally reduces the overall space occupation while maintaining full lint collection capability, resolving the contradiction between collection effectiveness and volume

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If the lint removal part is directly arranged on the clothing throw-in port, then lint can be scraped into the collection container, but the structure becomes scattered and occupies large space

Engineering Contradiction:
Improvelint scraping functionVSAvoidcomponent arrangement
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges the lint removal part with the collection container by positioning the removal part directly above and connected to the container. This integrated arrangement maintains the scraping function at the throw-in port area while eliminating the scattered layout, achieving ease of operation with a concise structure

Inventive Principle:
Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary

A clothes drying device, wherein a lint cleaning component (6) and a lint collecting component are both arranged on a mounting component, and the mounting component is arranged on a box body assembly, so that the lint cleaning component (6) and the lint collecting component are arranged at a centralized position in the clothes dryer. The present invention solves the problem in existing clothes dryers that a fiber removing component and a collecting container are arranged at dispersed positions on a clothes dryer and occupy a large amount of space, which affects the overall layout of the clothes dryer such that the overall structure of the clothes dryer is not compact, and downgrades the user experience.
