Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current shooting range target systems are labor-intensive and delay scoring, often requiring manual deployment and retrieval of targets, and typically use specialized equipment not commonly used in the field.
Innovation Solution
An automated shooting range target system using a target module with a digital camera, optional light source, and processor to detect hit locations by comparing before and after images, allowing for prompt scoring and reporting without the need for manual intervention or expensive sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual deployment and scoring of targets is used, then labor intensity is reduced, but scoring time is delayed and productivity decreases
Solution Approach 1:
The target system automatically detects hits, determines locations, and transmits scores without requiring manual intervention. The processor compares before and after images to self-determine hit locations, eliminating the need for operators to manually deploy and score targets.
Solution Approach 2:
The patent replaces manual mechanical operations with an automated optical-electronic system. A digital camera captures images, a processor analyzes them to detect hits, and results are transmitted electronically, substituting the mechanical manual scoring process with an automated digital system.
2Measurement precision
If specialized equipment such as lasers, microphones, or high speed photography is used, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses inexpensive, readily available components such as a standard digital camera instead of expensive high-speed photography equipment or specialized sensors. The system achieves accurate hit detection using common, low-cost technology rather than specialized expensive equipment.
Solution Approach 2:
The patent changes the detection approach from using specialized sensors to using color layer analysis in standard digital images. By detecting the appearance of a second color layer through a hole in the first color layer, the system achieves precise hit location detection using parameter changes in image data rather than specialized measurement equipment.
3Device complexity
If standard digital camera and image comparison are used, then device complexity is reduced, but measurement precision of hit location may be affected by target movement
Solution Approach 1:
The patent introduces color layers as an intermediary mechanism to mark hit locations. The first color layer and second color layer serve as visual markers that remain stable and identifiable in images, allowing the system to accurately determine hit locations even when the target moves between images.

Data Source
AI summary
A shooting range target system comprises one or more target modules, a server, a range master's display and a shooter's display. Target modules utilize a digital camera and a processor to automatically detect shot locations and communicate them to the server. Target modules may optionally deploy and retract targets and otherwise move targets based on commands received from the server. Shooter's scores are calculated and stored on the server, and displayed to the shooters on shooters' displays and optionally to a range safety officer on a range master's display.
