Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If water containing minerals is used in the steam module, then the steam generation function is achieved, but scale accumulates on the heater and water level sensor causing malfunction and fire risk

Engineering Contradiction:
Improvesteam module operation reliabilityVSAvoidscale accumulation
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent applies preliminary action by performing scale cleaning before the scale causes malfunction or fire hazards. The controller automatically initiates a cleaning cycle using a cleaning agent and heating element to dissolve and remove scale deposits from the heater and water level sensor, preventing the harmful effects before they occur.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent converts the harmful scale accumulation into a beneficial cleaning process. By introducing a cleaning agent that reacts with scale deposits and using the heating element to activate this reaction, the harmful scale is transformed into soluble substances that can be flushed away, turning a problematic byproduct into part of the solution.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

2Measurement precision

If scale accumulates on the water level sensor, then sensor energization occurs causing erroneous operation, but the water level detection function is compromised

Engineering Contradiction:
Improvewater level detection accuracyVSAvoidsensor energization error
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary cleaning of the water level sensor by circulating cleaning agent through the steam module before scale accumulation affects sensor accuracy. The controller monitors cleaning cycle completion to ensure the sensor is free from scale deposits that could cause erroneous energization.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The cleaning agent acts as an intermediary substance that selectively reacts with scale deposits on the water level sensor without affecting the sensor's electrical properties. This intermediary chemical process removes the harmful scale layer while preserving the sensor's measurement function.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If scale accumulates in the steam device, then fire risk increases due to heater malfunction, but the steam generation capability is maintained

Engineering Contradiction:
Improvefire safetyVSAvoidfire hazard
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The system implements preliminary fire prevention by automatically cleaning scale from the heater surface before it can build up to dangerous levels. The cleaning cycle uses chemical agents and heating to dissolve scale deposits, eliminating the fire hazard before it threatens the steam generation system.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent converts the potentially harmful scale buildup on the heater into a controlled cleaning process. By using chemical reactions initiated by the cleaning agent and activated by the heater itself, the scale is transformed into removable substances, turning a fire hazard into a routine maintenance opportunity.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

4Ease of operation

If scale is not cleaned regularly, then odor flows into the clothes care apparatus, but the steam function continues operating

Engineering Contradiction:
Improveodor controlVSAvoidodor contamination
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The system performs preliminary odor prevention by cleaning scale deposits before they decompose and generate odors. The regular cleaning cycle removes scale from all steam module surfaces, preventing the conditions that lead to odor formation and maintaining a fresh environment for clothes care.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent converts the potential odor problem from scale decomposition into a beneficial cleaning opportunity. By using the steam heating function to activate cleaning agent reactions with scale deposits, the system prevents odor formation while utilizing the existing steam generation capability for a dual-purpose benefit.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)
