Elastomeric Trigger Spacing Device for Firearm Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing training devices for firearms do not effectively address the spacing issue between the shooter's trigger finger and the firearm frame, leading to inconsistent shot placement and muscle memory development.
Innovation Solution
A firearm trigger spacing device comprising a band with a through-cavity, a first lobe extending radially from the outer circumference, and a ridge, made from a deformable elastomeric material, which fits around the shooter's index finger to provide consistent spacing and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no spacing device is used, then the shooter can operate the firearm freely, but the trigger finger placement is inconsistent and accuracy deteriorates
Solution Approach 1:
The spacing device acts as an intermediary tool between the shooter's trigger finger and the firearm frame. It provides a physical reference structure that guides the finger into the correct position and maintains consistent spacing, thereby improving shot placement reliability without restricting the shooter's ability to operate the firearm.
Solution Approach 2:
The spacing device is designed to be self-adjusting through its deformable elastomeric material that conforms to the shooter's finger anatomy. The device maintains its functional geometry while adapting to different users, providing consistent spacing guidance without requiring active adjustment or complex mechanisms.
2Measurement precision
If a rigid spacing structure is used, then trigger finger placement precision is improved, but the device becomes uncomfortable and difficult to operate
Solution Approach 1:
The spacing device utilizes a deformable elastomeric material that can be classified as a flexible shell. This material maintains the essential geometric features needed for precise spacing while being soft enough to be comfortable against the skin. The flexibility allows the device to conform to the shooter's finger contours, eliminating the discomfort associated with rigid structures.
Solution Approach 2:
The device employs material parameter changes by selecting elastomeric materials with specific durometer ranges (Shore A 10-50). This allows the spacing device to maintain structural integrity for precise measurement while possessing sufficient flexibility for comfort. The material properties are optimized to balance rigidity for accuracy with softness for wearability.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device helps shooters develop proper trigger finger placement and motion, leading to improved accuracy and consistent shot placement by maintaining the finger's position parallel to the firearm's barrel.
Implementation Method 1
made from at least one injection-molded deformable elastomeric material
