Solution Overview

Problem

The existing base assemblies for dryers are complex, making assembly and maintenance difficult, and the connection between the air duct shell and the base is intricate, leading to low assembly efficiency and high weight.

Innovation Solution

A modular design for the base assembly with a detachable bottom plate and air duct shell, where the connection members allow for independent formation and replacement of components, enabling easier assembly and maintenance, and allowing different materials for each part to reduce overall weight.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the base assembly is designed as an integrally molded piece, then the structural strength is improved, but the overall weight increases and the assembly and maintenance become inconvenient

Engineering Contradiction:
Improvestructural strengthVSAvoidoverall weight
Core Design Contradiction:
StrengthVSWeight of stationary object

Solution Approach 1:

The base assembly is divided into separate components: a base and an air duct shell that can be detached from each other. This segmentation allows each part to be optimized independently - the base can be made of lighter materials while the air duct shell maintains its structural integrity, thereby reducing overall weight while preserving necessary strength

Inventive Principle:
Principle #1Segmentation

2Strength

If the base assembly is designed as an integrally molded piece, then the structural strength is improved, but the disassembly and maintenance become inconvenient

Engineering Contradiction:
Improvestructural strengthVSAvoidmaintenance convenience
Core Design Contradiction:
StrengthVSEase of repair

Solution Approach 1:

The base assembly is segmented into a base and an air duct shell connected by detachable connection members. This allows the air duct shell to be easily removed for maintenance or replacement of the heat exchanger, while the base remains intact, thus improving maintenance convenience without compromising overall structural strength

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection between the base and air duct shell is made dynamic through detachable connection members that allow the structure to be assembled and disassembled as needed. This dynamic connection enables easy maintenance and replacement of components while maintaining structural integrity during operation

Inventive Principle:
Principle #15Dynamics

3Productivity

If the air duct shell and base are designed as separate pieces, then the assembly efficiency is improved, but the connection structure becomes complicated

Engineering Contradiction:
Improveassembly efficiencyVSAvoidconnection structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The base assembly is segmented into a base and an air duct shell that are separately manufactured and then assembled using simple connection members. This segmentation enables independent manufacturing of each component, improving assembly efficiency, while the connection structure is kept simple through the use of straightforward detachable fasteners

Inventive Principle:
Principle #1Segmentation

4Ease of repair

If the air duct shell and base are designed as separate pieces, then the maintenance convenience is improved, but the assembly difficulty increases

Engineering Contradiction:
Improvemaintenance convenienceVSAvoidassembly difficulty
Core Design Contradiction:
Ease of repairVSEase of operation

Solution Approach 1:

The base assembly is segmented into separately manufacturable components (base and air duct shell) that are connected through simple detachable connection members. This segmentation allows easy maintenance by detaching the air duct shell, while the assembly process remains simple due to the straightforward connection design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The detachable connection members enable the structure to transition between assembled and disassembled states easily. This dynamic design simplifies both assembly and maintenance operations, allowing workers to quickly connect or disconnect the air duct shell from the base without complex procedures

Inventive Principle:
Principle #15Dynamics
