Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple separate partitions are used to divide the cabinet into washing spaces, then the structure provides clear spatial separation, but the device complexity and assembly time increase

Engineering Contradiction:
Improvespatial separationVSAvoidpartition structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate partition walls into a single integrated partition wall that simultaneously divides the cabinet into a washing space and a drying space. This single partition wall structure achieves the same spatial separation function as multiple separate partitions would provide, thereby reducing device complexity and assembly requirements while maintaining reliable space division.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If multiple separate partitions are used to divide the cabinet, then clear spatial separation is achieved, but assembly time and costs increase

Engineering Contradiction:
Improvespatial separationVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent merges multiple separate partition walls into one integrated partition wall structure that performs all necessary spatial divisions. This reduces the number of components that need to be assembled, directly decreasing assembly time and associated costs while maintaining the required spatial separation between washing and drying areas.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If a single partition wall is used to divide the cabinet, then device complexity and assembly time are reduced, but the interior volume distribution may be limited

Engineering Contradiction:
Improvepartition structureVSAvoidinterior volume
Core Design Contradiction:
Device complexityVSVolume of moving object

Solution Approach 1:

The single partition wall is designed to extend in multiple dimensions within the cabinet space, creating efficient three-dimensional spatial division. By strategically positioning and dimensioning the partition wall, the design maximizes the usable volume of both the washing space and drying space, ensuring optimal interior volume distribution despite using a single partition structure.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
