Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional rocket ignition and chemical fuel burning is used, then rockets can be launched to required orbits, but launch preparation and maintenance time is long, preventing high-frequency rapid launches
Solution Approach 1:
The patent replaces the traditional chemical combustion propulsion system with an electromagnetic propulsion system. The electromagnetic launch device uses electromagnetic fields to accelerate the rocket along a guide track, eliminating the need for chemical fuel ignition and combustion processes. This substitution enables rapid repeated launches because the electromagnetic system can be reset and recharged quickly without the lengthy preparation and maintenance required by chemical rocket systems.
Solution Approach 2:
The patent implements preliminary energy storage and system preparation before each launch. The electromagnetic launch device stores energy in advance in capacitors or other energy storage systems, and the rocket is pre-positioned on the launch track. This preliminary action allows the launch to proceed rapidly when needed, as the energy and mechanical systems are already prepared, eliminating the need for last-minute fuel loading and system checks required by traditional rockets.
2Adaptability or versatility
If traditional rocket launch systems are used, then satellites can be launched, but the cost of rocket launches remains high compared to decreasing satellite costs
Solution Approach 1:
The patent replaces the chemical propulsion system with an electromagnetic propulsion system that uses stored electrical energy to generate electromagnetic forces for rocket acceleration. This eliminates the need for expensive chemical fuels and oxidizers, significantly reducing the cost per launch. The electromagnetic system can be powered by conventional electrical grids or renewable energy sources, making each launch much more cost-effective compared to traditional rocket fuel costs.
Solution Approach 2:
The patent changes the fundamental energy parameter from chemical energy storage in fuel to electrical energy storage in capacitors or other electrical systems. This parameter change allows for more efficient energy utilization and lower cost per unit of energy delivered to the rocket, directly addressing the cost-effectiveness issue while reducing the quantity of consumable materials required for each launch.
3Adaptability or versatility
If traditional rocket launch manner is used, then large load and high orbit launches are achieved, but launching opportunities are limited and flexibility is seriously lacking
Solution Approach 1:
The patent implements a dynamic electromagnetic launch system where the electromagnetic field parameters (strength, duration, frequency) can be adjusted in real-time based on the rocket's position, mass, and desired trajectory. This dynamic control allows the same launch device to accommodate different rocket sizes, payloads, and orbital destinations, providing extensive launching flexibility and increasing the number of viable launching opportunities compared to the fixed-parameter traditional rocket systems.
Solution Approach 2:
The electromagnetic launch device is designed as a universal platform that can launch various types of rockets and payloads to different orbits. The system's electromagnetic propulsion mechanism can be adapted to different mass ranges and mission requirements through parameter adjustment, making it a multi-functional launch system that increases launching opportunities across different satellite classes and orbital destinations, unlike traditional systems optimized for specific launch profiles.
