Firearm Hand Muff With Expandable Openings for Cold-Weather Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hunters and gun users are exposed to adverse weather conditions that affect their ability to grip and grasp firearms effectively, necessitating a protector that safeguards their hands while allowing contact with the gun.
Innovation Solution
A gun/hand muff with expandable and contractable openings that accommodate the gun and user's hand, providing direct or indirect contact, and includes insulation and hand-warmers for protection and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hand is exposed to grip the gun directly, then the grip strength and control are improved, but the hand is adversely affected by cold, rainy, and snowy conditions
Solution Approach 1:
The patent introduces a hand protector as an intermediary device between the user's hand and the gun. This protector allows the hand to grip the gun while simultaneously protecting it from adverse weather conditions such as cold, rain, and snow, thus resolving the contradiction between maintaining grip strength and protecting from environmental harm.
Solution Approach 2:
The hand protector is designed to be inserted over the gun's hand grip area, creating a nested structure where the protector envelops the gun portion that contacts the hand. This nesting allows the hand to grip through the protector without direct exposure to elements, maintaining operational effectiveness while providing protection.
2Object-affected harmful factors
If a protector is placed between the hand and the gun, then protection from elements is improved, but direct contact and grip control may be reduced
Solution Approach 1:
The hand protector is constructed from flexible material that can conform to the gun's shape and the user's hand. This flexibility ensures that the protector does not create excessive bulk or rigidity that would interfere with grip control, while still providing effective protection from cold, rain, and snow.
Solution Approach 2:
The protector is designed with dynamic characteristics that allow it to move and flex with the user's hand during gripping and manipulating the gun. This dynamic design maintains tactile feedback and control while providing continuous protection from environmental elements.
3Object-affected harmful factors
If the protector covers the entire hand and gun contact area, then protection is maximized, but the complexity of the device increases
Solution Approach 1:
The hand protector is segmented into distinct portions: a first portion that receives and protects the user's hand, and a second portion that covers the gun's hand grip area. This segmentation allows each portion to be optimized for its specific function while keeping the overall structure relatively simple and manageable.
Solution Approach 2:
The protector is designed to perform multiple functions simultaneously: protecting the hand from elements, maintaining grip control, and accommodating different gun types. This multi-functionality reduces the need for multiple separate devices, thereby simplifying the overall system while maximizing protection coverage.

AI summary
A gun/hand muff for protecting portions of a gun user's hand, wrist, and/or forearm from the elements is provided. The gun/hand muff defines an interior cavity for ultimately receiving portions of a gun and portions of at least a gun user's hand and possibly portions of the gun user's wrist and forearm therein. The interior cavity is used to protect portions of the gun and the gun user's hand (and possibly portions of the gun user's wrist and forearm) from the elements, while simultaneously affording contact of the gun user's hand with the portions of the gun received in the interior cavity.
