Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shooting range facilities with interactive targets face issues when the target support plate is tilted, as this causes parallax errors that deform the target representation, making it difficult to accurately locate impacts.
Innovation Solution
A shooting range facility with a target support plate that can be tilted to various angles, featuring target representations with deformations that maintain identical orthogonal projections across different inclinations, ensuring the target appears undistorted to the shooter, along with optional calculators and detectors to adjust and display these deformations electronically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the target support plate is tilted to protect the impact surface from high-energy shots, then the resistance to impact energy is improved, but the target representation becomes deformed due to parallax errors
Solution Approach 1:
The target representation is pre-deformed in the opposite direction of the expected parallax distortion caused by tilting. This preliminary deformation compensates for the distortion that will occur when the plate is tilted, ensuring the target appears undistorted to the shooter while maintaining the protective tilt angle.
Solution Approach 2:
The geometric parameters of the target representation are changed based on the tilt angle. By calculating and applying specific deformation parameters that correspond to the tilt angle, the target maintains its visual accuracy despite the physical tilt of the support plate.
2Productivity
If the target support plate is tilted to redirect projectiles into a recovery bin, then the productivity of projectile recovery is improved, but the target representation becomes deformed
Solution Approach 1:
The target representation is pre-deformed to compensate for the parallax distortion that will occur when the plate is tilted for projectile redirection. This ensures accurate target display while maintaining the productivity benefits of tilting for projectile recovery.
Solution Approach 2:
The solution addresses the two-dimensional target display problem by introducing a third dimension - the tilt angle. By pre-deforming the target in the plane of the tilted plate, the system maintains accurate target representation across multiple dimensions simultaneously.
3Duration of action of stationary object
If the target support plate is tilted at higher angles to protect from powerful shots, then the duration of impact surface life is extended, but the target representation deformation increases
Solution Approach 1:
The target representation is pre-deformed according to the specific tilt angle that will be used. This preliminary deformation compensates for parallax errors, allowing the plate to be tilted at higher angles for extended protection without sacrificing target accuracy.
Solution Approach 2:
The geometric parameters of the target representation are adjusted based on the tilt angle parameters. By changing the target's shape parameters in advance to match the intended tilt angle, the system extends the usable life of the impact surface while maintaining precision.

AI summary
A shooting range facility that is for recreational or sporting purposes includes a target support plate, which can be tilted according to several different possible inclinations with respect to a reference plane, and at least one target representation intended to be displayed in a plane of the target support plate. Each target representation has several different displayable deformations, respectively associated with the several different possible inclinations, these different deformations being designed so that the orthogonal projections thereof in the reference plane are all identical when they are respectively displayed in the plane of the target support plate according to the inclinations with which they are respectively associated.
