Firearm Forend with Integrated Light Switches and Ergonomic Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearm-mountable lights with on-off switches are difficult to locate and activate, especially in high-stress or low-visibility scenarios, and existing forends are challenging to hold onto, leading to safety and efficiency issues for users.
Innovation Solution
A firearm-mountable light with a dual-switch assembly and a forend design featuring a grip portion and finger slot, where the switches are integrated into the housing, allowing for easy activation by the user's forward-located hand, and the forend's ergonomic design enhances grip security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If switches are made small to reduce device size, then device complexity is reduced, but ease of operation deteriorates as switches become difficult to locate and activate
Solution Approach 1:
The patent positions switches on the forend housing in a location that utilizes the dimensional space along the barrel axis, allowing the forward-located hand to access switches without requiring the hand to move to a different position or the user to look away from the target. This spatial arrangement resolves the contradiction by making switches easily locatable and activatable while maintaining compact dimensions.
2Device complexity
If forend grip portion is made compact to reduce size, then device complexity is reduced, but ease of operation deteriorates as grip security is compromised
Solution Approach 1:
The forend grip portion incorporates localized texturing or surface treatment at specific contact points where the user's fingers naturally rest. This creates enhanced friction and grip security only at these critical locations while maintaining an overall compact and simple forend structure. The local quality modification resolves the contradiction by providing secure grip without increasing overall device complexity.
3Ease of manufacture
If switches are positioned away from the grip portion to avoid interference, then ease of manufacture is improved, but ease of operation deteriorates as switches become harder to reach
Solution Approach 1:
The patent integrates the switch assembly directly into the forend housing structure, merging the switch mounting function with the existing forend components. This integration allows switches to be positioned in an optimal location that is easily accessible to the forward-located hand while simplifying the overall manufacturing process by reducing the number of separate components and assembly steps.
