Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional solid barrier is used to block munitions and drones, then protection reliability is improved, but the device weight and installation complexity increase significantly
Solution Approach 1:
The patent employs a cable net structure composed of flexible cables arranged in a grid pattern, replacing traditional solid rigid barriers. The cable net maintains protective function while significantly reducing weight and installation complexity, as cables can be easily tensioned and anchored without requiring heavy structural support frameworks.
Solution Approach 2:
The barrier is segmented into individual cable elements forming a net structure, where each cable acts as an independent load-bearing element. This segmentation allows the system to achieve high reliability through redundancy while keeping individual components lightweight and easy to install or replace.
2Strength
If a heavy-duty net structure is used to withstand multiple munition hits, then strength and durability are improved, but ease of transport and deployment deteriorates
Solution Approach 1:
The cable net utilizes flexible cable elements that can be easily rolled or folded for transport, then rapidly deployed and tensioned into position. The flexibility of individual cables allows the entire structure to be lightweight yet strong when assembled, resolving the contradiction between transport ease and structural strength.
Solution Approach 2:
The cable net employs high-strength cable materials with optimal strength-to-weight ratios, combining material strength with a lightweight modular net structure. This allows the system to withstand multiple munition hits while remaining easy to transport and deploy.
3Reliability
If a fine-mesh net is used to prevent drone penetration, then protection against small objects is improved, but material consumption and manufacturing complexity increase
Solution Approach 1:
The cable net employs different cable diameters and spacing in different regions of the structure. Areas requiring higher drone interception capability have finer mesh or thicker cables, while less critical areas use coarser spacing, optimizing material consumption while maintaining overall protection reliability.
Solution Approach 2:
The cable net utilizes an open mesh structure with controlled porosity that allows it to intercept drones through the netting while maintaining material efficiency. The porous cable net design provides sufficient drag and entanglement effect for drone interception without requiring solid continuous coverage, reducing material consumption.
4Stability of the object's composition
If a rigid 3D structure is used to maintain shape under impact, then structural integrity is improved, but adaptability to different deployment locations deteriorates
Solution Approach 1:
The cable net structure is dynamically adjustable, allowing the tension and geometry of individual cables to be modified during deployment to adapt to different site conditions and anchor point configurations. This dynamic adjustability maintains structural integrity under impact while providing versatility for various deployment locations.
Solution Approach 2:
The cable net combines flexible individual cable elements into a unified 3D protective structure through tension and geometric configuration. This merging of simple flexible elements creates a stable overall structure that can adapt to different deployment scenarios while maintaining integrity under impact loads.
