Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple treating apparatuses are stacked vertically to save space, then the productivity and functionality are improved, but the risk of electrical short circuits and malfunctions increases due to potential unintentional electrical connections between units

Engineering Contradiction:
Improvelaundry treatment capacityVSAvoidelectrical connection safety
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

An insulating support structure is introduced as an intermediary element between the upper and lower treating apparatuses. This support structure includes insulating members that physically separate the two units and prevent electrical contact, while still providing mechanical support for stacking. The insulating support acts as a mediator that enables the beneficial stacking arrangement while eliminating the harmful electrical connection risk.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If each treating apparatus has its own separate manipulation unit and display, then the operational independence of each unit is improved, but the user convenience deteriorates due to the need to separately identify and control multiple apparatuses

Engineering Contradiction:
Improveoperational independenceVSAvoiduser control convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The manipulation units and displays of the upper and lower treating apparatuses are merged into a single integrated control panel. This unified interface allows users to control and monitor both washing and drying operations simultaneously through one display and one set of controls, eliminating the need to separately interact with multiple independent control systems while maintaining the functional independence of each treating unit.

Inventive Principle:
Principle #5Merging (Combining)

3Stability of the object's composition

If treating apparatuses are directly coupled without insulating supports, then the structural stability is improved, but the electrical insulation between units is compromised leading to potential short circuits

Engineering Contradiction:
Improvestructural coupling stabilityVSAvoidelectrical short circuit risk
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The support structure is designed as a composite system combining insulating materials with mechanical support elements. The insulating support structure includes insulating members made of non-conductive materials that provide both structural stability for coupling the upper and lower apparatuses and electrical insulation to prevent short circuits. This composite approach integrates both mechanical and electrical protection functions into a single support system.

Inventive Principle:
Principle #40Composite materials
