Firearm Scope Cap with Iris Diaphragm for Glare Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional scope caps increase tactical risk when opened, as they expose a large surface area and can reflect light, and do not allow for partial coverage of the scope lens to reduce glare.
Innovation Solution
An internal scope cap with an iris diaphragm that can be adjusted to expose or cover the scope lens, featuring a pivotable blade actuator and a secondary protective lens to reduce glare and glint, designed to be modular and aesthetically appealing, matching high-end rifle optics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional scope cap is opened to operate the scope, then the scope lens is exposed for use, but the exposed surface area increases tactical risk and light reflection occurs
Solution Approach 1:
The scope cap is segmented into multiple adjustable iris blades that can independently control the aperture opening. This allows the lens to be partially covered while remaining operational, reducing exposed surface area and light reflection while maintaining sufficient light transmission for scope use.
Solution Approach 2:
The scope cap transitions from a static traditional design to a dynamic iris diaphragm system with adjustable blades. The cap can be dynamically adjusted between fully closed, partially open, and fully open positions, allowing the user to optimize the balance between protection and operational visibility in real-time.
2Reliability
If a traditional scope cap is used in closed position, then the scope lens is protected from dust and debris, but the scope cannot be operated
Solution Approach 1:
The iris diaphragm provides dynamic adjustability between fully closed (protected) and fully open (operational) states, along with intermediate positions. This eliminates the need to completely remove the cap for operation, allowing the user to maintain protection while enabling scope functionality when needed.
Solution Approach 2:
The scope cap serves multiple functions simultaneously: it protects the lens from dust and debris when closed, allows full operation when fully open, and provides partial coverage with glare reduction in intermediate positions. This multi-functionality eliminates the need for separate protective measures during operation.
3Ease of operation
If a traditional scope cap is fully opened, then the scope can be operated, but glare and light reflection increase
Solution Approach 1:
The iris diaphragm segments the light path through multiple adjustable blades. By partially closing the blades while maintaining an open aperture for scope operation, the system reduces the amount of direct light and glare entering the lens while still allowing sufficient light transmission for effective scope use.
Solution Approach 2:
Instead of fully opening the cap (excessive action) or keeping it fully closed (insufficient action), the iris diaphragm allows partial opening to the exact degree needed. This partial action optimizes the balance between operational visibility and glare reduction, providing just enough opening for effective scope operation while minimizing harmful light reflection.

AI summary
An internal scope cap affixes onto a scope for a firearm to protect and enclose a scope lens of the scope. The internal scope cap includes an iris diaphragm and a scope mount. The iris diaphragm allows the user to adjust an iris opening to expose or enclose the scope lens. The iris opening is formed from a plurality of iris blades that are manipulated through a blade actuator. As the blade actuator is rotated, the diameter of the iris opening is adjusted proportionately to the angular rotation. The iris diaphragm is removably connected to the scope mount to allow the user to interchange and remove the iris diaphragm from the scope mount. The scope mount affixes the internal scope cap onto the scope of the firearm. A glare-reduction lattice and a protective lens are implemented to reduce glint and glare to the user, while gazing through the scope.
