Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compounds with flavoring agents have low chemical structural stability at room temperature, leading to insufficient fire recognition due to volatilization of flavor ingredients, which delays fire detection in buildings.
Innovation Solution
A wallpaper composition containing a novel compound represented by Formula 1, which includes a carbonate linking group to protect the flavoring compound at room temperature and thermally decompose into volatile lactones and flavor ingredients upon heating, allowing rapid fire recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing compounds with flavoring agents are used, then flavor expression function is provided, but chemical structural stability is low causing structural transformation or decomposition at room temperature
Solution Approach 1:
The patent applies preliminary action by pre-protecting the flavoring compound's hydroxyl group with a carbonate linking group containing a metal atom. This protective action is performed in advance to prevent spontaneous decomposition at room temperature, while the protection is designed to be removable under fire conditions. The compound structure is prepared beforehand with the metal-containing carbonate group that will decompose thermally to release the flavoring agent when needed.
Solution Approach 2:
The patent utilizes parameter changes by designing the compound to undergo thermal decomposition at elevated temperatures (fire conditions). The metal-containing carbonate linking group is stable at room temperature but decomposes at higher temperatures, transforming from a protected state to a flavor-releasing state. This temperature-dependent parameter change allows the compound to maintain stability during normal conditions while activating flavor expression during fire events.
2Loss of information
If flavor ingredients are released by thermal decomposition, then fire recognition is enabled, but delayed detection occurs when no fire alarm or malfunctioning fire alarm exists
Solution Approach 1:
The patent applies the principle of sensory changes by using volatile flavor ingredients that produce distinctive odors (such as lactone and menthol flavors) when thermally decomposed. These olfactory signals serve as detectable indicators of fire, allowing people to recognize fire conditions through smell when electronic fire alarm systems are unavailable or malfunctioning. The flavor release creates a sensory warning that can be detected by human olfaction.
Solution Approach 2:
The patent implements self-service by designing the wallpaper composition to automatically release flavoring agents in response to fire heat without requiring external activation. The thermal decomposition process is self-triggered by the fire environment itself, and the released volatile compounds serve as the detection signal. This eliminates the need for separate fire alarm devices, as the wallpaper material itself provides the fire recognition function.
3Reliability
If compound structure is stabilized at room temperature, then structural transformation is prevented, but flavor ingredient volatilization is reduced
Solution Approach 1:
The patent applies dynamics by designing a compound structure that transitions from a stable protected state at room temperature to an active flavor-releasing state under fire conditions. The metal-containing carbonate linking group dynamically changes its stability characteristics based on temperature, being stable during normal conditions and decomposing under thermal stress. This dynamic behavior allows the same compound to satisfy both stability and flavor expression requirements under different conditions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition thermally decomposes to release volatile lactones and flavor ingredients, enabling early fire detection even at a distance from the ignition point, facilitating timely evacuation.
Implementation Method 1
the compound may be thermally decomposed to be decomposed into a flavoring compound and a lactone compound
Implementation Method 2
volatile flavor ingredients (e.g., lactone and/or menthol flavors) rapidly diffuse from a part close to the flame of a building on fire to the entire building
