Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If induction heating is used to generate vapour, then controlled heating and vapour generation is achieved, but unsuitable temperatures are unknowingly produced wasting power and risking damage

Engineering Contradiction:
Improveheating temperatureVSAvoidpower waste
Core Design Contradiction:
TemperatureVSLoss of energy

Solution Approach 1:

The system continuously monitors temperature at the body using a temperature sensor and feeds this information back to the controller. The controller compares the monitored temperature with the target temperature from the heating profile and adjusts the power supplied to the heating device accordingly, preventing both overheating and power waste.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system dynamically changes the power supply parameters (amount and profile of power) based on the monitored temperature and the predetermined heating profile. This ensures the body reaches and maintains the optimal temperature while minimizing energy consumption.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If temperature monitoring is implemented, then temperature control is improved, but factors like body age and type are not considered affecting performance

Engineering Contradiction:
Improveperformance reliabilityVSAvoidmonitoring system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by determining the body's characteristics (age, type, presence) before and during heating. This early identification allows the controller to select appropriate heating profiles and parameters tailored to the specific body characteristics, improving reliability without requiring complex real-time adjustments.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The temperature sensor and controller serve multiple functions: monitoring temperature, determining body presence, assessing body characteristics (age and type), and controlling power supply. This multi-functionality improves reliability while minimizing the addition of separate monitoring components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If power is continuously supplied to heat the body, then vapour generation is maintained, but the body degrades over time reducing efficiency and safety

Engineering Contradiction:
Improvevapour generation efficiencyVSAvoidsafety and efficiency
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system dynamically adjusts the heating profile and power supply based on the body's real-time characteristics and degradation state. As the body degrades, the system modifies heating parameters to maintain optimal efficiency and safety, rather than using a static heating approach.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The continuous monitoring of temperature and body characteristics provides feedback that allows the system to detect body degradation. The controller uses this feedback to adjust power supply and heating profiles, maintaining safety and efficiency even as the body degrades over time.

Inventive Principle:
Principle #23Feedback
