Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protection systems fail to detect unauthorized access when layers are split without damaging trip wires, and intruders can evade detection using x-ray imaging by tracing the topology of conduction layers.
Innovation Solution
A three-dimensional net with arbitrary shape formed by conduction layers and connection elements, where insulation layers are dielectric and light-proof, making it impossible to track or split without damaging the layers, and a detection circuit measures resistance changes to detect penetration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional conduction layers with regular topology are used, then the detection circuit can measure resistance changes, but intruders can detect the topology using x-ray and avoid touching the connection lines
Solution Approach 1:
The patent applies asymmetry by using irregular, non-uniform connection line patterns in the conduction layers. Instead of regular grid patterns that are easy to trace with x-ray, the connection lines are arranged in asymmetric, random-looking paths that make it difficult for intruders to predict and avoid them while maintaining electrical connectivity for resistance measurement
Solution Approach 2:
The patent transitions from two-dimensional planar patterns to three-dimensional layered structures. Multiple conduction layers are stacked with connection elements vertically connecting them, creating a 3D network that is much harder to trace with conventional x-ray imaging while preserving the electrical measurement function
2Reliability
If trip wires are placed on shield layers, then unauthorized access can be detected through short circuit or open circuit situations, but layers can be split without harming the trip wires
Solution Approach 1:
The patent divides the conduction path into multiple segments across different layers, connected by discrete connection elements. This segmentation means that splitting any single layer will necessarily interrupt at least one connection element or conduction path, making tamper detection possible while maintaining system functionality
Solution Approach 2:
The patent embeds multiple conduction layers within each other, with connection elements penetrating through intermediate insulation layers to connect adjacent conduction layers. This nested structure ensures that any attempt to split or separate layers will damage the embedded connection elements, triggering detection
3Reliability
If continuous connection lines are used on top and bottom layers, then electrical connectivity is maintained, but the topology becomes traceable and predictable
Solution Approach 1:
The patent replaces straight, linear connection lines with curved, serpentine, or circular paths. These curved trajectories increase the path length and complexity without adding straight-line predictability, making it harder for intruders to trace the connection topology while maintaining continuous electrical connectivity for resistance measurement
