Firearm Training Device Blank Bolt Sensor System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing training systems for firearm weapons face challenges in providing a realistic and environmentally friendly training experience, as traditional blank ammunition causes environmental harm, safety risks, and is costly and unreliable.
Innovation Solution
A training device and system that includes a blank bolt assembly with a movable blank bolt, a sensor arrangement to detect the movement of the blank bolt and the position/orientation of the weapon, a clock unit for time information, and a logic unit to gather and store information into an information package for analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional blank ammunition is used for training, then realistic weapon handling experience is provided, but environmental harm, safety risks, and cost increase
Solution Approach 1:
The patent creates a simplified copy of the bolt assembly (blank bolt assembly) that replicates the essential movement and mechanical actions of the real bolt without containing actual ammunition. This copy performs the same training function (simulating weapon operation) while eliminating the harmful effects of real blank ammunition such as powder discharge, metal debris, and environmental contamination.
Solution Approach 2:
The invention extracts and removes the harmful components (live ammunition, powder charges, metal casings) from the training system while retaining the essential training function through the blank bolt assembly. The blank bolt assembly isolates the useful mechanical movement from the harmful byproducts, allowing training without environmental harm or safety risks.
2Measurement precision
If sensor arrangements are added to detect blank bolt movement, then measurement precision improves, but device complexity increases
Solution Approach 1:
The logic unit serves multiple functions: it processes sensor signals to detect blank bolt movement, determines shot events, records training data, and controls the overall training system. By making the logic unit multi-functional, the patent achieves precise measurement capabilities without proportionally increasing device complexity, as one component performs several critical roles.
Solution Approach 2:
The patent combines the sensor arrangement, logic unit, and recording functions into an integrated system where the logic unit centrally coordinates detection and data processing. This merging of functions into a unified control architecture achieves measurement precision while managing system complexity through centralized intelligence rather than distributed complexity.
