Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shooting training systems using laser beams face issues with malfunction and inefficiency due to the need for multiple light-receiving diodes, which can be affected by surrounding light sources, making it difficult to accurately detect hits and adjust zeroing.
Innovation Solution
A shooting training system that projects shooting images on a screen and uses a camera module with a laser filter to recognize only the laser beam, allowing users to check if the laser hits the aimed point, eliminating the need for separate detection devices and improving system reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple light-receiving diodes are arranged in a lattice form to detect laser beams, then the detection coverage is improved, but the device complexity increases and malfunction risk increases
Solution Approach 1:
The patent extracts the detection function from multiple complex light-receiving diodes and implements it using a single camera module with a laser filter. This simplifies the device structure while maintaining detection capability, as the camera module can capture the entire shooting screen area without requiring multiple discrete sensors arranged in a lattice.
Solution Approach 2:
The camera module serves multiple functions: it acts as both the detection device for laser beams and the display device for showing shooting results. This multi-functionality eliminates the need for separate detection devices and reduces overall system complexity while improving reliability.
2Measurement precision
If light-receiving diodes are used to detect laser beams, then hit detection is enabled, but surrounding light sources cause disturbance and malfunction
Solution Approach 1:
The patent converts the harmful effect of surrounding light into a beneficial filtering mechanism by using a laser filter that specifically blocks ambient light wavelengths while allowing laser beam wavelengths to pass through. This enables the camera to distinguish the laser beam from surrounding light sources, eliminating malfunction caused by light interference.
Solution Approach 2:
The laser filter changes the optical parameters by selectively transmitting only specific wavelengths corresponding to the laser beam while blocking other wavelengths from surrounding light sources. This wavelength-based parameter change enables accurate hit detection without interference from ambient light.
3Reliability
If an invisible laser is used for shooting training, then safety is improved, but zeroing and adjustment become impossible
Solution Approach 1:
The patent uses a visible red laser beam instead of an invisible laser, allowing shooters to see the aimed point and perform zeroing and adjustment. The red color provides visual feedback while maintaining sufficient visibility for training purposes, resolving the contradiction between safety and operational capability.
4Measurement precision
If a separate detection device is used to detect laser hits, then hit detection accuracy is improved, but the system complexity and cost increase
Solution Approach 1:
The camera module performs dual functions as both the display device for showing shooting targets and results, and the detection device for capturing laser beam impact points. This eliminates the need for separate detection devices, reducing system complexity and cost while maintaining accurate hit detection capability through the laser filter.
