Solution Overview
Problem
Existing protective equipment often uses conventional materials with constant cross-sections and minimal layers, failing to provide customized protection based on anatomical traits, which can lead to inefficiencies in weight, breathability, and effectiveness in absorbing and distributing impact forces.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional materials with constant cross-section and minimal layers are used, then manufacturing simplicity is maintained, but customized protection based on anatomical traits is lost
Solution Approach 1:
The patent applies local quality by creating different lattice cell types (first and second lattice cell types) with varying structural properties in different regions of the protective equipment. This allows each region to be optimized for specific anatomical requirements, such as higher density in areas requiring more protection and lower density in areas requiring flexibility or breathability.
Solution Approach 2:
The protective equipment is segmented into multiple layers with different lattice cell types, where each layer can be independently designed and manufactured. This segmentation enables customized protection for different body regions while allowing for modular manufacturing processes.
2Reliability
If multiple layers with varying lattice cell types are implemented, then customized protection and impact absorption are improved, but manufacturing complexity increases
Solution Approach 1:
The patent utilizes parameter changes by varying the lattice cell type, density, and structural parameters across different layers and regions. This allows optimization of impact absorption characteristics while maintaining manufacturability through systematic parameter variation rather than completely different structural approaches.
Solution Approach 2:
The protective equipment employs composite structures combining different lattice cell types within a unified design framework. This composite approach enables enhanced impact absorption through material heterogeneity while leveraging advanced manufacturing techniques to manage complexity.
3Reliability
If customized multi-layer structure is created, then protection effectiveness is optimized, but weight and breathability are compromised
Solution Approach 1:
The patent implements local quality by varying lattice cell density and structure locally rather than uniformly throughout the entire protective equipment. High-density lattice structures are placed only where impact protection is most needed, while low-density or open-cell structures are used in regions requiring breathability and flexibility, thereby optimizing the weight-protection trade-off.
Solution Approach 2:
The patent employs porous lattice structures with varying porosity levels to create regions that provide protection while maintaining breathability. The porous design allows for controlled mass distribution, enabling lightweight construction without sacrificing protective effectiveness in critical areas.
