Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hydraulic cylinder with soft rubber sealing is used to erect the rocket, then the erection function is achieved, but the rubber sealing is damaged by side loads from ship movement causing hydraulic oil leakage
Solution Approach 1:
A guide member is introduced as an intermediary component between the sliding member and the driving cylinder. The guide member constrains the sliding member to move only along its longitudinal direction, preventing side loads from transmitting to the driving cylinder. This mediator protects the hydraulic seal from damage while maintaining the erection function.
Solution Approach 2:
The erection system is segmented into distinct functional components: the driving cylinder provides driving force, the sliding member translates this force, and the guide member constrains the motion path. This segmentation isolates the hydraulic cylinder from side loads by separating the driving function from the guiding function.
2Reliability
If a backup hydraulic system is set up to ensure launch quality, then the reliability is improved, but the space requirement exceeds the limited space on the launch vessel
Solution Approach 1:
The guide member is installed beforehand to prevent side loads from affecting the driving cylinder during operation. This prior protective measure eliminates the need for backup hydraulic systems while maintaining launch quality, as the single hydraulic system operates without side load contamination.
3Productivity
If the driving cylinder is positioned close to the rocket for efficient erection, then the erection efficiency is improved, but the high-temperature flame damages the hydraulic system
Solution Approach 1:
The driving cylinder is extracted from the high-temperature zone near the rocket and positioned at a safe distance. The connecting member (sliding member and connecting rod) acts as an extended mechanism to transmit the driving force from the remote cylinder to the rocket, maintaining erection efficiency while protecting the hydraulic system from thermal damage.
4Adaptability or versatility
If the ship moves at sea with horizontal acceleration and tilting, then the marine launch capability is achieved, but side forces are generated on the erection device
Solution Approach 1:
The guide member changes the dimension of motion constraint by allowing movement only along its longitudinal axis while preventing movement in perpendicular directions. This dimensional constraint isolates the driving cylinder from side forces generated by ship motion, enabling marine launch capability without transmitting harmful forces to the hydraulic system.
