Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid ballistic panels are used in personal protective vests, then safety protection is improved, but freedom of movement and flexibility deteriorate
Solution Approach 1:
The patent replaces rigid ballistic panels with flexible ballistic panels made from layered material segments including ultra-high molecular weight polyethylene fiber based composite laminates and para-aramid materials. This flexible panel construction maintains ballistic protection while allowing freedom of movement and flexibility for the security personnel wearing the vest.
Solution Approach 2:
The patent employs composite materials consisting of multiple layered material segments with different ballistic materials (ultra-high molecular weight polyethylene fiber based composite laminates and para-aramid materials) to achieve both high safety protection and flexibility. The composite structure combines the strengths of different materials to resolve the contradiction between protection and mobility.
2Reliability
If rigid ballistic panels are sown into the vest, then protection is improved, but comfort and flexibility deteriorate
Solution Approach 1:
The rigid ballistic panels are replaced with flexible ballistic panels constructed from layered material segments that can conform to the body's movements. The flexible nature of these panels provides comfort to the wearer while maintaining the required protection level against ballistic threats.
Solution Approach 2:
The ballistic panel system is designed to be dynamic and adaptable to movement rather than static and rigid. The flexible panels can flex and move with the wearer's body, providing comfort during various physical activities while maintaining protective capabilities.
3Ease of operation
If flexible armor panels are used, then comfort and flexibility are improved, but safety protection may deteriorate
Solution Approach 1:
The patent uses composite materials comprising ultra-high molecular weight polyethylene fiber based composite laminates and para-aramid materials in a layered configuration. This composite construction ensures that the flexible panels maintain high safety protection levels while providing the desired flexibility and comfort for the wearer.
Solution Approach 2:
The patent changes the material parameters by using ultra-high molecular weight polyethylene fiber based composite laminates with specific areal density (about between 226 g/m2 and 240 g/m2) and combining them with para-aramid materials. These parameter changes enable the flexible panels to achieve both flexibility and high safety protection simultaneously.
