Helicopter Target Launcher With Integrated Spin-and-Release Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shooting target launchers lack efficient mechanisms for rotating and launching targets without dedicated prime movers, and often require complex control systems or two-handed operation, which can be cumbersome and inefficient.
Innovation Solution
A shooting target launcher with a housing, target connector, and motor that rotates the target about an axis of rotation, utilizing sensorless motor control and a launch control system to launch targets after reaching a desired rotational speed, allowing single-handed operation and efficient target launching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated prime mover is used to move the target retainer between retaining and release configurations, then the target launching mechanism is more reliable, but the device complexity increases
Solution Approach 1:
The patent combines the target retainer movement function with the existing target connector rotation mechanism. The retainer is moveable by rotation of the target connector itself, eliminating the need for a separate dedicated prime mover. This merging of functions reduces device complexity while maintaining reliable target launching through the integrated mechanical linkage.
2Measurement precision
If discrete control is added to move the target retainer to release configuration, then the launch timing precision is improved, but the device complexity increases
Solution Approach 1:
The target retainer is configured to move automatically to the release configuration through the rotational motion of the target connector. The mechanism uses the existing rotational movement to self-trigger the retainer release without requiring separate discrete control signals or additional control systems, achieving precise launch timing through passive mechanical coupling.
3Reliability
If two-handed operation is required to operate the shooting target launcher, then the operational safety is improved, but the ease of operation deteriorates
Solution Approach 1:
The target connector serves multiple functions: it rotates to spin the target for launching, and its rotation also drives the target retainer from retaining to release configuration. This multi-functionality allows single-handed operation where one hand can simultaneously control target engagement, rotation, and release, improving ease of operation while maintaining safety through the integrated control mechanism.
4Measurement precision
If a complex control system is used to control the prime mover, then the launch precision is improved, but the device complexity increases
Solution Approach 1:
The target connector acts as an intermediary mechanical element that translates rotational motion into both target spinning and retainer release. This mechanical intermediary provides precise launch timing through pure mechanical coupling rather than electronic control systems, achieving launch precision while avoiding complex control electronics.

AI summary
A shooting target launcher, associated components and methods. The launcher spins one or more helicopter-like shooting targets to launch the targets. A target connector receives the targets. The target connector is rotated about an axis of rotation to rotate the targets about the axis of rotation. The targets have fan blades that, when rotated, propel the target through the air.
