Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If simple fuel tank structure is used, then device complexity is reduced, but explosion-proof performance deteriorates
Solution Approach 1:
The patent implements a nested tank structure where inner tanks are placed inside an outer tank, forming a multi-layer containment system. The inner tank holds the fuel while the outer tank provides additional protection and isolation, creating a nested configuration that enhances explosion-proof performance without excessive complexity increase.
Solution Approach 2:
The patent employs composite wall structures combining different materials with distinct functions. The walls incorporate heat insulation layers, explosion-proof layers, and corrosion-resistant materials in a composite configuration, providing multiple protective functions simultaneously while managing system complexity.
2Reliability
If multiple explosion-proof layers are added to tank walls, then explosion-proof performance is improved, but device complexity increases
Solution Approach 1:
The patent applies different material properties and thicknesses to different parts of the tank wall based on local requirements. The wall structure includes varying layers such as heat insulation sections, explosion-proof sections, and corrosion-resistant sections positioned according to specific operational needs, optimizing protection where required while minimizing unnecessary complexity.
Solution Approach 2:
The tank wall utilizes a composite structure with multiple functional layers including heat insulation material, explosion-proof material, and corrosion-resistant material. Each layer serves a specific protective function, and their combination creates a multi-functional wall system that addresses multiple hazards simultaneously.
3Reliability
If inner tank and outer tank are isolated, then explosion-proof performance is improved, but heat dissipation performance deteriorates
Solution Approach 1:
The patent introduces a heat dissipation medium filling the space between the inner tank and outer tank. This intermediary substance serves dual purposes: it maintains the isolation required for explosion-proof performance while simultaneously facilitating heat transfer from the inner tank to the outer tank, thereby resolving the contradiction between safety and thermal management.
