Dynamic Anthropometric Acquisition for Weapon Fitment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing static anthropometric data sets are inadequate for accurately measuring dynamic functions such as gripping and triggering actions, as they fail to account for variables like muscle compression, joint angles, and hand deformation, which are crucial for proper fitment of handguns and tools.
Innovation Solution
An anthropometrics acquisition apparatus comprising a forearm cradle, adjustable grips, and devices to measure dynamic trigger finger pull length and force, providing three-dimensional dynamic anthropometric data for improved fitment and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If static 2D anthropometric data is used for measurement, then measurement simplicity is maintained, but measurement precision deteriorates because it cannot capture dynamic hand functions during gripping and triggering
Solution Approach 1:
The measurement system transitions from static 2D anthropometric data collection to dynamic 3D measurement that captures hand deformation, muscle compression, and joint angle changes during actual gripping and triggering actions. The apparatus measures hand dimensions in multiple dimensions while the hand is actively engaged in functional tasks, providing accurate dynamic anthropometric data that reflects real-world usage conditions
Solution Approach 2:
The system expands measurement from two-dimensional static data to three-dimensional dynamic measurement by adding temporal and spatial dimensions. Multiple sensors positioned at different locations capture hand morphology changes during gripping, trigger pull, and weapon manipulation, creating a comprehensive 3D model that accounts for muscle compression, tendon effects, and joint rotation
2Adaptability or versatility
If static anthropometric data is used, then data collection is simple, but adaptability deteriorates because it cannot account for hand deformation during dynamic use
Solution Approach 1:
The system performs preliminary measurement of hand dimensions under various dynamic conditions (different grip types, trigger pulls, weapon orientations) before final fitment determination. By capturing hand morphology data across multiple functional states, the system pre-establishes a comprehensive profile that enables accurate weapon customization and selection
Solution Approach 2:
The measurement system varies multiple parameters simultaneously including hand position, grip force, trigger pull distance, and weapon orientation to capture the full range of hand deformation. This multi-parameter approach allows the system to adapt measurements to specific usage scenarios and individual user characteristics
