Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gun calibrators face issues with limited usability under intense light due to low visibility of laser light and poor coaxiality with the barrel, leading to calibration errors and frequent battery replacements.
Innovation Solution
A gun calibrator with an inner red dot sight, featuring a straight bar, coaxial laser module, and a detachable battery cabin, utilizing a Picatinny rail system for height adjustment and a conical expansion sleeve for improved coaxiality, along with a conductive assembly for efficient power supply and easy battery replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single laser module is used for calibration, then the structure is simple, but the visibility is poor under intense light conditions
Solution Approach 1:
The patent combines a laser module and a red dot sight into a single integrated calibration device. The laser module provides a visible laser beam for alignment, while the red dot sight projects a red dot pattern that remains visible under intense light conditions. This merging of two different light sources into one device allows the calibration tool to function effectively in both indoor and outdoor environments without requiring separate devices.
2Duration of action of moving object
If a large volume battery is installed to extend usage time, then battery endurance is improved, but the weight and size of the device increase
Solution Approach 1:
The battery cabin is designed as a detachable module that can be separated from the main calibration device. This segmentation allows users to remove the heavy battery when not needed for extended usage, significantly reducing the device weight for portability. When long duration operation is required, the battery can be attached to provide extended power supply without permanently increasing the device's base weight.
3Strength
If the straight bar is made rigid to maintain structural stability, then the strength is improved, but the coaxiality with the barrel deteriorates due to deformation
Solution Approach 1:
The straight bar incorporates a flexible section that allows the bar to bend and conform to the barrel's axis. This dynamic flexibility compensates for manufacturing tolerances and structural deformation, maintaining coaxiality between the laser module and the barrel during insertion and calibration. The flexible section acts as a mechanical tolerance compensation mechanism that preserves alignment precision despite the rigidity needed for structural strength.
4Measurement precision
If the laser module is positioned at the front end for accurate alignment, then the calibration accuracy is improved, but the battery power is insufficient due to limited space
Solution Approach 1:
The device is segmented into a compact front section containing the laser module for accurate alignment, and a separate detachable battery cabin that can be attached to the rear. This segmentation allows the front end to maintain precise positioning for calibration accuracy while the battery capacity is determined by the separately attachable cabin, which can be optimized for power supply without compromising the front module's alignment precision.
