Solution Overview

Problem

Existing shooting targets provide poor indication of shooting results, typically through small holes, necessitating a more effective method for real-time detection of hits.

Innovation Solution

A shooting target system with inflatable targets connected to a blower, power source, controller, and current meter, where current changes upon a hit are detected to provide real-time indications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If traditional shooting targets with small hole indications are used, then the structure is simple, but the indication of shooting results is poor

Engineering Contradiction:
Improveshooting result indicationVSAvoidsystem complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system implements feedback by continuously monitoring the electrical current consumed by the blower and comparing it to reference values. When a shot hit occurs, the air pressure inside the target changes, causing the blower to work harder and draw more current. This current change is detected and processed to generate a shot hit indication, providing real-time feedback to the shooter without requiring complex visual or electronic display systems.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The invention replaces traditional mechanical or visual indication systems (such as flags, lights, or digital displays) with an electrical measurement system. Instead of using mechanical components to indicate hits, the system uses electrical current measurement to detect changes in air pressure caused by shot hits, thereby substituting a simple electrical sensing mechanism for complex mechanical or electronic indication systems.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If real-time hit detection is implemented, then user feedback is enhanced, but device complexity increases

Engineering Contradiction:
Improvehit detection accuracyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system employs the blower's own electrical current consumption as the detection mechanism. The blower serves dual purposes: maintaining air pressure in the target and providing the sensing mechanism for hit detection. When a shot hit occurs, the change in air pressure automatically alters the blower's current draw, which is then detected by the current sensor. This self-service approach eliminates the need for separate sensors or complex detection systems.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system detects shot hits by monitoring changes in the electrical current parameter consumed by the blower. When a shot penetrates the target, the internal air pressure changes, causing the blower to adjust its operation and draw different current. By continuously monitoring this current parameter and comparing it to reference values, the system can reliably detect hits in real-time without requiring complex multi-parameter measurement systems.

Inventive Principle:
Principle #35Parameter changes

AI summary

A method for detecting a shot hit on an inflatable shooting target and for providing a real-time indication of the hit. The method includes the step of providing a shooting target system with one or more inflatable shooting targets, each of them is assembled on a blower, a power source that is connected to each blower through a controller that controls the activation of each blower, and a current meter between the controller and the power source. The method includes the second step of measuring the current that flow to a certain blower, detecting changes in the current level that occurs upon a hit in a certain inflatable shooting target that is assembled on that certain blower, and making and indication of the hit by turning off the certain blower or by sending a notification to a mobile device of the user or the operator.
