Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional detonating fuses are used in explosive devices, then the explosive device can be detonated, but safety measures for controlled ignition and timing are lacking, posing risks in mining and military operations
Solution Approach 1:
The patent changes the material parameters of the detonating fuse by using carbon nanotubes with specific structural characteristics (chirality, diameter, length) and coating them with oxidizing materials. This enables controlled combustion rates and timing precision, resolving the contradiction between reliability and safety risks through material parameter optimization
Solution Approach 2:
The patent creates a composite structure by coating carbon nanotubes with oxidizing materials such as metal oxides or organic peroxides. This composite material provides both the structural integrity of CNTs and the controlled oxidation capability, enabling safe and precise detonation while reducing harmful effects
2Reliability
If a CNT wire structure is used with oxidizing material coating, then controlled ignition and combustion characteristics are achieved, but the device complexity increases
Solution Approach 1:
The patent segments the detonating fuse into distinct functional components: the carbon nanotube wire structure provides the combustion pathway, while the oxidizing material coating provides the controlled oxidation reaction. This segmentation allows each component to be optimized independently for its specific function, achieving controlled ignition without excessive overall complexity
Solution Approach 2:
The oxidizing material coating acts as an intermediary between the carbon nanotube structure and the oxygen environment. It controls the rate and manner of oxidation, enabling precise timing and combustion characteristics while simplifying the overall system by eliminating the need for complex ignition control mechanisms
