Solution Overview

Problem

Existing steam generators for ironing stations face challenges with calcification, leading to high maintenance requirements, reduced service life, safety risks, and ineffective decalcification, especially in regions with hard water, due to the inability to reliably remove deposits from the boiling chamber and boiler walls.

Innovation Solution

An automatic decalcification system that uses a control device to activate the water supply, heating element, and outlet means to perform decalcification without pressure, with a descaling solution, and includes user guidance and sensors to ensure timely and effective descaling based on water hardness and usage parameters, preventing calcification buildup.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual maintenance is required for decalcification, then the system structure remains simple, but maintenance burden increases and reliability decreases

Engineering Contradiction:
Improvemaintenance burdenVSAvoidsystem structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system automatically performs decalcification by activating the water supply device, heating element, and outlet means through a control device, eliminating the need for manual intervention. The control device monitors operating parameters and triggers decalcification cycles automatically, allowing the system to maintain itself without user involvement.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs decalcification at predetermined maintenance intervals before calcification becomes severe. The control device schedules and executes decalcification cycles proactively based on accumulated operating time or usage parameters, preventing calcification buildup rather than reacting to it after it occurs.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If regular manual decalcification is performed, then calcification is reduced, but time loss and operational interruption increase

Engineering Contradiction:
Improveservice lifeVSAvoidmaintenance time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system implements periodic decalcification cycles at predetermined intervals determined by the control device. These cycles are scheduled automatically based on operating parameters such as total operating time or water usage volume, ensuring maintenance occurs regularly without requiring user attention or causing operational disruption.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The decalcification process is integrated into the normal operation schedule without requiring system shutdown or user intervention. The control device manages the decalcification cycles to maintain continuous operational capability, minimizing interruption to the useful function of the steam generator.

Inventive Principle:
Principle #20Continuity of useful action

3Ease of operation

If simple rinsing is used for decalcification, then the system remains simple to operate, but it is insufficient for hard water regions

Engineering Contradiction:
Improveoperational simplicityVSAvoideffectiveness of decalcification
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system changes the parameters of the water in the boiling chamber during decalcification by heating it to specific temperatures and controlling the duration of heating cycles. The control device adjusts temperature and time parameters to create conditions that effectively dissolve and remove calcification deposits, making the process effective for hard water regions while remaining automatic and simple to operate.

Inventive Principle:
Principle #35Parameter changes

4Reliability

If pressure is applied during decalcification, then water penetration improves, but safety risks and device complexity increase

Engineering Contradiction:
Improvedecalcification effectivenessVSAvoidsafety risks
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system uses temperature and time parameter changes rather than pressure to achieve effective decalcification. The control device heats the water in the boiling chamber to specific temperatures and maintains it for predetermined periods, allowing thermal energy to dissolve and flush out calcification deposits without applying pressure, thereby eliminating safety risks associated with pressurized decalcification.

Inventive Principle:
Principle #35Parameter changes
