Solution Overview
Problem
Current chemiluminescent systems are ineffective at low temperatures, particularly below −110 degrees Celsius, which limits their application in winter and high-altitude conditions, where they fail to produce sufficient light for military and non-military training, emergency situations, and other uses.
Innovation Solution
A chemiluminescent system comprising an activator system with a combination of solvents, peroxides, and catalysts, including trialkyl citrates, dialkyl phthalates, glycols, glycol ethers, hydrogen peroxide, and specific catalysts, which maintains a liquid state from −110 degrees Celsius to 75 degrees Celsius, producing light with intensities between 0.1 and 35,000 1×.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional chemiluminescent systems are used, then they work well at room temperature, but they fail to produce sufficient light at low temperatures below -110 degrees Celsius
Solution Approach 1:
The patent changes the physical and chemical parameters of the chemiluminescent system by using a eutectic solvent mixture with a depressed freezing point (-110°C to -150°C) instead of traditional single solvents. This parameter change allows the system to maintain liquid state and chemical reactivity at low temperatures, thereby maintaining light output in cold environments
Solution Approach 2:
The patent employs a composite solvent system combining multiple components (e.g., glycols, esters, and other solvents in specific ratios) to create a eutectic mixture. This composite material approach enables the solvent to remain liquid at temperatures below the freezing point of individual components, resolving the contradiction between low temperature operation and sufficient light production
2Reliability
If the solvent is kept in liquid state at low temperatures, then the chemiluminescent reaction can proceed, but the viscosity and freezing point become critical constraints
Solution Approach 1:
The patent utilizes phase transition principles by designing a eutectic solvent system that undergoes a controlled phase transition at a specific low temperature (-110°C to -150°C). This allows the system to maintain liquid phase at operating temperatures while having a predictable freezing point, ensuring reaction reliability without being constrained by high freezing points of traditional solvents
3Illumination intensity
If light intensity is increased for better visibility, then the reaction efficiency improves, but the duration of light emission may be reduced
Solution Approach 1:
The patent applies dynamics by formulating the chemiluminescent system with adjustable component ratios and concentrations that allow optimization of the reaction kinetics. The eutectic solvent system enables control over the reaction rate and energy release profile, allowing the system to achieve both high light intensity and extended duration by balancing the chemical composition and reaction conditions
