Overlapping Single-Wire Patches for Multi-Impact Hit Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hit detection systems using wire grids struggle to accurately locate impact points when multi-fragment interceptors hit, leading to reduced detection probability and accuracy for subsequent impacts due to broken wires affecting the entire grid coverage.
Innovation Solution
A single wire patch design with overlapping patches is used, where each patch is monitored for continuity to determine impact location, allowing for flexible configuration and eliminating 'dead spots' caused by multi-fragment impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a wire grid system is used to detect impact locations, then the detection coverage area is large, but the detection accuracy decreases when multi-fragment interceptors hit because broken wires affect entire grid coverage
Solution Approach 1:
The wire grid system is segmented into multiple independent wire patches, where each patch is monitored separately. This segmentation isolates the effect of wire breaks to individual patches rather than affecting the entire grid, thereby maintaining detection accuracy for multi-fragment impacts while preserving overall coverage area.
2Device complexity
If traditional wire break monitoring is used in a grid system, then the system structure is simple, but the reliability of subsequent impact detection decreases after initial impacts
Solution Approach 1:
The grid is divided into independent wire patches that can be monitored separately. When a wire breaks in one patch, only that patch's detection capability is affected, while other patches remain fully operational. This segmentation maintains high reliability for detecting subsequent impacts without requiring complex system architecture.
3Measurement precision
If overlapping wire patches are implemented to eliminate dead spots, then the detection accuracy improves, but the device complexity increases
Solution Approach 1:
The detection surface is covered with overlapping wire patches that provide redundant coverage. Each patch is simple in structure, but the overlapping arrangement ensures that no dead spots exist between patches. This approach achieves high detection accuracy while keeping individual patch complexity low.
Solution Approach 2:
Multiple wire patches are merged in an overlapping configuration to eliminate dead spots. The patches work together to provide continuous coverage across the detection surface, improving impact location accuracy without requiring each individual patch to be complex.

AI summary
In an approach to single wire hit detection, an apparatus comprises: a plurality of hit detection patches, each of the plurality of hit detection patches comprising an associated single coiled wire, and each of the plurality of hit detection patches being disposed overlapping at least one other hit detection patch of the plurality of hit detection patches; and a controller coupled to the associated single coiled wire of each hit detection patch of the plurality of hit detection patches, the controller configured to determine a location of one or more of the plurality of hit detection patches impacted by a projectile.
