Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional inflatable closed capsules are used for marine anti-collision, then the device structure is simple, but the protection capability is limited and the device slips or is misplaced during collision
Solution Approach 1:
The single inflatable capsule is divided into multiple modular units, each equipped with independent airbags and control systems. This segmentation allows each module to independently absorb collision energy from different directions, preventing slippage and misplacement while providing comprehensive protection coverage.
Solution Approach 2:
The airbag protection device transitions from a static structure to a dynamic system with real-time adjustment capabilities. The intelligent control assembly monitors collision parameters and dynamically adjusts airbag inflation pressure and mechanical transmission angles to optimize protection effectiveness during actual collision events.
2Reliability
If waste tires are used for marine anti-collision, then the device complexity is low, but the appearance is affected and protection capability is limited
Solution Approach 1:
The system replaces solid waste tires with pneumatic airbag structures that can be inflated to provide cushioning protection. The airbags expand upon collision to absorb impact energy, offering superior protection capability while maintaining a cleaner appearance and enabling controlled deployment through the gas supply assembly.
3Reliability
If rubber balls are used for marine anti-collision, then the device structure is simple, but the protection is only effective during docking and cannot respond to emergencies
Solution Approach 1:
The airbag protection device is pre-installed and pre-configured on the ship hull, with all necessary mechanical transmission assemblies and gas supply systems in place. Upon detecting a collision risk, the intelligent control assembly rapidly inflates the airbags, providing immediate emergency protection without requiring manual intervention or additional setup time.
Solution Approach 2:
The system incorporates autonomous detection and response capabilities through the intelligent control assembly, which automatically monitors for collision risks, calculates optimal protection parameters, and triggers airbag deployment without human intervention. The mechanical transmission assemblies self-adjust to optimize airbag orientation based on detected collision angles.
4Reliability
If the airbag protection device is deployed, then the protection coverage is improved, but the space occupation increases
Solution Approach 1:
The airbags are designed to nest within the modular housing structures when deflated, with the mechanical transmission assemblies and gas supply components compactly integrated into the same housing. Upon deployment, the airbags expand outward to provide protection coverage while maintaining a compact footprint when not in use, minimizing space occupation on the ship hull.
