Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple separate partitions are used to divide the cabinet into washing spaces, then the structural stability and separation of functions are improved, but the device complexity and assembly time increase

Engineering Contradiction:
Improvestructural stabilityVSAvoidnumber of partitions
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate partition walls into a single integrated partition structure that divides the cabinet into a washing space and a drying space. This single partition wall performs the function of multiple separate partitions while reducing the total number of components, simplifying assembly, and maintaining structural stability through its integrated design.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If multiple separate partitions are used to divide the cabinet, then the functional separation is improved, but the assembly time and manufacturing costs increase

Engineering Contradiction:
Improvefunctional separationVSAvoidassembly time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The single partition wall integrates multiple functions including space division, structural support, and air flow management. By combining these functions into one component, the patent reduces assembly time while maintaining clear functional separation between the washing space and drying space through the partition's design features.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If a single partition wall is used to divide the cabinet, then the device complexity and assembly time are reduced, but the structural stability may be compromised

Engineering Contradiction:
Improvenumber of partitionsVSAvoidstructural stability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The single partition wall is designed as a robust integrated structure that combines space division and structural support functions. The partition includes features such as air supply units and flow paths integrated into its structure, providing both simplified assembly and adequate structural stability to maintain cabinet integrity.

Inventive Principle:
Principle #5Merging (Combining)

4Reliability

If the air supply unit is permanently fixed to the partition wall, then the structural stability is improved, but the ease of repair and maintenance deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidair supply unit replacement
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The air supply unit is designed as a detachable component that can be separated from the partition wall. This segmentation allows the air supply unit to be easily removed and replaced for maintenance or repair while maintaining a stable connection during normal operation. The detachable design enables independent access to the air supply unit without disassembling the entire partition structure.

Inventive Principle:
Principle #1Segmentation
