Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a heat shield is designed to protect CMDS equipment from high temperatures, then the equipment reliability is improved, but the device complexity increases due to additional shielding components and insulation layers
Solution Approach 1:
The patent implements a nested structure where the CMDS equipment is positioned inside the exhaust outlet, and the heat shield is nested around the exhaust outlet. The insulation layer is nested between the heat shield and the exhaust outlet surface. This nested arrangement protects the equipment from heat while maintaining a compact integrated design.
Solution Approach 2:
The patent introduces an intermediary heat shield structure between the hot exhaust gases and the CMDS equipment. The shield acts as a mediator that blocks thermal radiation and conduction. Additionally, an insulation material serves as an intermediary layer to further reduce heat transfer to the equipment.
2Temperature
If insulation material is coated on the inner surface of the heat shield, then heat protection effectiveness is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent applies insulation material specifically on the inner surface of the heat shield that faces the exhaust outlet, rather than uniformly insulating the entire structure. This localized insulation approach focuses thermal protection where it is most needed while reducing overall manufacturing complexity and material usage.
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
Effectively protects CMDS equipment from heat, ensuring its operational integrity and effectiveness.
Implementation Method 1
at least one protrusion extending from the casing outwardly from an opening through which the launcher unit fires a cartridge, and at an angle to a direction in which the cartridges are positioned along the launcher unit, thereby protecting the launcher unit from hot air by striking the hot air coming from the gas discharge element to the protrusion and directing it outwards from the launcher unit
Implementation Method 2
an insulation material resistant to combustion and high temperature should be chosen and coated on an inner surface of the titanium heat shield
Implementation Method 3
The heat shield design is made of a titanium material, which is one of the metal materials with the lowest heat permeability on the outer surface
