Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a detoxification device is disposed to remove toxic substances from fuel, then the toxic substance removal capability is improved, but the system cost increases and structural complexity increases
Solution Approach 1:
The patent extracts the fuel detection function from a complex detoxification system and implements it as a standalone detection mechanism. By placing fuel detectors at specific locations (upper and lower portions of the fuel tank) and using vent pipes with specific configurations, the system can detect toxic fuel leaks without requiring expensive detoxification devices, thus reducing system complexity while maintaining safety functionality.
Solution Approach 2:
The patent employs simple, low-cost detection components such as fuel detectors and vent pipes instead of expensive detoxification devices. These simple detection elements provide effective toxic fuel monitoring without the high cost and complexity of active detoxification systems, aligning with the principle of using inexpensive components to achieve the desired safety function.

3Object-affected harmful factors
If conventional detoxification devices are used, then toxic substance removal is achieved, but the system cannot cope with fuel gas leaks containing toxic substances
Solution Approach 1:
The patent creates a multi-functional detection system that can handle both liquid toxic fuel and its vaporized form. By configuring fuel detectors at both upper and lower portions of the fuel tank and using vent pipes that extend to the upper portion, the system simultaneously monitors liquid fuel quality and detects vaporized fuel leaks, achieving universal coverage for both liquid and gaseous toxic fuel states.
Solution Approach 2:
The patent adds a vertical dimension to fuel detection by placing detectors at different heights (upper and lower portions of the fuel tank). This multi-level detection approach enables the system to detect both liquid fuel conditions at the bottom and vaporized fuel conditions at the top, thereby expanding the detection capability from a single point to a three-dimensional monitoring system that covers both liquid and gaseous phases.
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 system effectively manages and safely discharges toxic fuel leaks, preventing diffusion and ensuring safety by detecting and responding to toxic substance leaks, thus reducing costs and complexity.
Implementation Method 1
The fuel is detected by using the fuel detector disposed at a lower portion of the case when the vapor specific gravity of the fuel is higher than a predetermined threshold. The fuel is detected by using the fuel detector disposed at an upper portion of the case when the vapor specific gravity of the fuel is lower than the predetermined threshold.

AI summary
[Problem] An engine system that can cope with a fuel gas that leaks from an engine and contains a toxic substance is provided. [Solution] An engine system 1 including an engine 2 that operates by a fuel containing a toxic substance includes a case 7 that surrounds the engine 2 and a fuel detector 8 that is disposed inside or outside the case 7 and detects the fuel that has leaked to the outside of the engine 2. The fuel is detected by using the fuel detector 8 disposed at a lower portion of the case 7 when the vapor specific gravity of the fuel is higher than a predetermined threshold. The fuel is detected by using the fuel detector 8 disposed at an upper portion of the case 7 when the vapor specific gravity of the fuel is lower than the predetermined threshold. The fuel containing the toxic substance is either ammonia or methanol.
