Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vapor generating devices are inadequate for producing controlled vapor at high pressures up to 30 PSI (207 kPa) required for advanced internal combustion engine systems, as they often result in spontaneous combustion or decreased vapor density, and rely on hazardous inert gases like nitrogen or carbon dioxide.
Innovation Solution
A smoke generating device with a capillary system, heating element, and temperature control, using compressed air as a propellant, which maintains vaporization between 225°F and 450°F (107°C and 232°C) to prevent dieseling, and includes a pressure regulator and flow restrictor to manage pressure and flow rates effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If existing vapor generating devices are used to produce vapor at high pressures, then vapor delivery capability is improved, but spontaneous combustion or dieseling occurs
Solution Approach 1:
The patent applies parameter changes by precisely controlling the heating temperature to remain below the ignition point of the vaporizing material while maintaining high pressure vapor generation. This temperature parameter control prevents spontaneous combustion and dieseling, resolving the contradiction between achieving high pressure vapor delivery and avoiding harmful combustion effects.
2Stress or pressure
If existing vapor generating devices are used to produce vapor at high pressures, then vapor delivery capability is improved, but vapor density decreases
Solution Approach 1:
The patent utilizes parameter changes by optimizing the heating temperature control to maintain vapor density while operating at high pressures. By keeping the temperature below the ignition point but sufficient for vaporization, the system achieves both high pressure delivery and maintained vapor density, resolving the contradiction between pressure and vapor quantity.
3Object-affected harmful factors
If inert gases like nitrogen or carbon dioxide are used as propellants, then safety is improved, but operational cost and complexity increase
Solution Approach 1:
The patent applies the extraction principle by removing the requirement for hazardous inert gases from the system. By using controlled temperature heating with compressed air instead of inert gas propellants, the invention eliminates the need for special gas storage and handling systems, thereby reducing operational costs and system complexity while maintaining safety through temperature control below ignition points.
4Adaptability or versatility
If mineral oil vapor is used for leak detection, then compatibility with hydrocarbon systems is improved, but risk of combustion increases
Solution Approach 1:
The patent applies parameter changes by严格控制 the heating temperature to remain below the ignition temperature of mineral oil vapor while maintaining sufficient heat for effective vaporization. This temperature parameter control enables the use of mineral oil vapor for leak detection in hydrocarbon systems without increasing combustion risk, thus resolving the contradiction between system compatibility and combustion safety.
