Adjustable Brass Shield Adaptor for Shooting Range Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shooting ranges face challenges in preventing 'hot brass' from ejecting semi-automatic weapons from hitting adjacent shooters due to varying ceiling heights and the inability of existing shields to fully contain ejected casings.
Innovation Solution
A shooting stall brass shield adaptor system comprising a first brass shield with a base for attachment to a panel and a second adjustably attachable brass shield, featuring openings for secure fastening and accommodating different ceiling orientations, ensuring complete containment of ejected brass.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed brass shield is used at standard height, then it protects against hot brass ejection at typical angles, but it fails to protect when ceiling heights vary or when guns are held at different angles
Solution Approach 1:
The brass shield is made adjustable in height and angle through a mechanism involving a vertical rail with holes and a horizontal arm with adjustment slots. This allows the shield to dynamically adapt to different ceiling heights and gun angles, resolving the contradiction between fixed protection effectiveness and variable environmental conditions.
Solution Approach 2:
The shield's position parameters (height and angle) can be changed by selecting different holes in the vertical rail and adjusting the horizontal arm to different slots. This parameter adjustment enables the same shield to effectively protect against hot brass ejection across varying ceiling heights and shooting angles.
2Reliability
If the brass shield is made taller to cover higher ejection angles, then protection against high-angle brass improves, but the shield becomes more complex and harder to install
Solution Approach 1:
The shield is divided into two main segments: a vertical component with a rail and holes for height adjustment, and a horizontal arm with slots for angle adjustment. This segmentation allows each component to be simple and easy to manufacture while collectively providing comprehensive protection against high-angle brass ejection.
Solution Approach 2:
Rather than making a single complex tall shield, the system uses adjustable segments that can be positioned to achieve the required height and angle. This dynamic adjustment simplifies the individual components while maintaining effective protection.
3Ease of manufacture
If standard shields are used without adjustment mechanisms, then manufacturing and installation are simpler, but they cannot accommodate varying ceiling heights and orientations
Solution Approach 1:
The shield system is segmented into adjustable components (vertical rail with holes, horizontal arm with slots) that can be easily manufactured separately and then assembled. This segmentation maintains ease of manufacture while enabling adaptation to various ceiling orientations through simple positional adjustment.
Solution Approach 2:
The adjustable shield mechanism serves multiple functions: it accommodates different ceiling heights, adjusts to various shooting angles, and adapts to different orientations. This multi-functionality is achieved through simple adjustment features rather than multiple specialized shields, maintaining ease of manufacture.
