Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing flavoring compounds are used, then flavoring function is provided, but chemical structural stability at room temperature deteriorates causing premature volatilization

Engineering Contradiction:
Improvechemical structural stabilityVSAvoidvolatilization of flavor ingredients
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent introduces a protecting group (intermediary substance) that temporarily binds to the flavoring compound to prevent its premature volatilization. This protecting group acts as a mediator between the flavoring compound and the environment, stabilizing the compound at room temperature while allowing controlled release under fire conditions.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the chemical parameters of the flavoring compound by introducing a protecting group that modifies its physical and chemical properties. This transformation alters the compound's stability, volatility, and release characteristics, enabling it to remain stable at room temperature while releasing flavor ingredients when exposed to fire temperatures.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If flavoring compounds are stabilized at room temperature, then chemical structural stability improves, but fire recognition capability deteriorates due to reduced volatilization

Engineering Contradiction:
Improvechemical structural stabilityVSAvoidfire recognition capability
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent utilizes phase transition concepts by designing a system that transitions from a stable, non-volatile protected state at room temperature to a volatile, flavor-releasing state under fire conditions. The protecting group is designed to decompose or transform when exposed to elevated temperatures, enabling the flavoring compound to volatilize and provide fire recognition signals.

Inventive Principle:
Principle #36Phase transitions

Solution Approach 2:

The patent applies preliminary action by pre-stabilizing the flavoring compound with a protecting group before fire occurs. This preliminary stabilization prevents premature volatilization, but the protecting group is designed to be removed or transformed when fire conditions are reached, thereby enabling timely fire recognition through flavor ingredient release.

Inventive Principle:
Principle #10Preliminary action

3Speed

If volatile flavor ingredients are released quickly, then fire recognition speed improves, but chemical structural stability at room temperature deteriorates

Engineering Contradiction:
Improvefire recognition speedVSAvoidchemical structural stability
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The patent applies dynamics by creating a system with different stability characteristics under different conditions. The flavoring compound is dynamically stabilized at room temperature through the protecting group, but this stabilization is not permanent - the system transitions to a volatile state when exposed to fire, enabling quick fire recognition while maintaining room temperature stability during normal conditions.

Inventive Principle:
Principle #15Dynamics
