Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the cubesat is tightly fixed in the container unit to protect from vibrations, then protection from launch environment is improved, but the separation reliability deteriorates
Solution Approach 1:
The spring unit provides a dynamic coupling mechanism that adapts between launch and deployment phases. During launch, the spring maintains tight fixation to protect against vibrations. During deployment, the spring naturally releases to enable clean separation, resolving the contradiction between secure fixation and reliable separation.
Solution Approach 2:
The protrusion-groove coupling mechanism is pre-configured on both the cubesat and deployer before launch. This preliminary configuration ensures that when the spring releases, the cubesat and deployer can immediately engage or disengage reliably without requiring additional activation mechanisms, thus ensuring separation reliability while maintaining protection during launch.
2Object-affected harmful factors
If the cubesat is securely fixed to prevent movement during launch, then protection from launch environment is improved, but the ability to inspect operation state deteriorates
Solution Approach 1:
The deployer is segmented into distinct functional units: the container unit for protection, the spring unit for deployment, and the communication connection unit for inspection. This segmentation allows the cubesat to be securely fixed during launch while enabling independent communication operations through the dedicated communication connection unit that interfaces with the cubesat's communication device.
3Object-affected harmful factors
If the container unit is designed to fully enclose the cubesat for protection, then protection from launch environment is improved, but the complexity of the deployer increases
Solution Approach 1:
Multiple functions are merged into the container unit: it serves as both the protective enclosure during launch and the mounting structure for the spring unit and communication connection unit. By combining these functions into a single integrated container rather than separate components, the design provides full protection while minimizing overall structural complexity.
