Motorized Target Holder with Remote Control and Level Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional target holders require users to approach and manually replace targets, which can lead to delays when multiple shooters are using the stand, and they lack the ability to automatically change targets or adjust for uneven ground.
Innovation Solution
A target holder system with a motorized roll assembly, remote control, and level adjustment mechanism that automatically advances targets and adjusts for unlevel surfaces, allowing for remote operation and continuous shooting without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual target replacement is used, then device complexity is reduced, but productivity decreases due to waiting time between targets
Solution Approach 1:
The system automatically replaces targets without human intervention. The motorized roll mechanism advances the next target into position automatically, and the optical sensor detects when replacement is needed, enabling the system to service itself and eliminate waiting time between targets.
Solution Approach 2:
Manual mechanical target replacement is replaced with an automated motorized system. The motor-driven roll mechanism substitutes for manual rolling, and the optical sensor substitutes for visual detection, creating an automated control loop that eliminates human intervention in target replacement.
2Ease of operation
If remote target replacement is implemented, then ease of operation improves, but device complexity increases due to additional components
Solution Approach 1:
A remote control device acts as an intermediary between the operator and the target holder system. The remote transmits signals wirelessly to the motor control circuit, allowing the operator to control target replacement from a distance without directly interacting with the mechanical components.
Solution Approach 2:
The optical sensor provides feedback to the motor control circuit about target position and replacement status. This feedback loop enables automatic control of the motorized roll mechanism, ensuring targets are replaced at the appropriate times without requiring constant manual monitoring.
3Adaptability or versatility
If level adjustment assembly is added, then adaptability to uneven ground improves, but device complexity increases
Solution Approach 1:
The level adjustment assembly transforms the static frame into a dynamically adjustable structure. The adjustable legs can be independently positioned to compensate for uneven ground, allowing the frame to adapt its configuration to various terrain conditions while maintaining operational stability.
4Productivity
If motorized roll assembly is implemented, then productivity increases through automatic target advancement, but use of energy increases
Solution Approach 1:
The motor operates periodically rather than continuously, activating only when target replacement is needed as detected by the optical sensor. This intermittent operation mode enables continuous shooting capability while minimizing energy consumption by keeping the motor stationary during stable target periods.
