Interchangeable Scope Lens Covers With Elastic Press Fit Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scope lens covers are either opaque, fixed, or require time to activate, leading to reduced visibility in changing conditions, and often fail to fit multiple scope sizes, allowing moisture and debris to enter.
Innovation Solution
An interchangeable scope lens cover system with elastic cords providing a press fit seal, allowing quick lens changes and selection from various types, and accommodating different scope sizes through adjustable and customizable lens covers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If opaque scope covers are used to protect lenses, then lens protection is improved, but visibility and speed of employment are worsened
Solution Approach 1:
The scope cover is divided into two separate covers (objective end cover and ocular end cover) that can be independently removed. This segmentation allows the user to quickly remove only the necessary cover for the current shooting condition without removing the entire scope cover assembly, thereby improving both protection and speed of employment.
Solution Approach 2:
The scope cover system transitions from a static, fixed state to a dynamic, movable state through the use of elastic cords that allow the covers to be easily attached and detached. This dynamic design enables rapid deployment and removal of covers, resolving the contradiction between protection and speed of employment.
2Illumination intensity
If fixed transparent covers are used to maintain visibility, then visibility is improved, but adaptability to different lighting conditions is worsened
Solution Approach 1:
The scope cover system allows dynamic adjustment of transparency by providing both transparent and shaded covers that can be interchanged based on lighting conditions. This dynamic adaptability resolves the contradiction between maintaining visibility and adapting to different lighting environments.
Solution Approach 2:
The system changes the optical parameters of the scope cover by offering different types of covers (transparent for low light, shaded for bright light) that can be selected based on ambient lighting conditions. This parameter change capability allows the user to optimize visibility while adapting to various lighting environments.
3Device complexity
If fixed lens covers are used to simplify design, then device complexity is reduced, but versatility across different scope sizes is worsened
Solution Approach 1:
The elastic cord attachment mechanism provides universal compatibility across different scope sizes and configurations. The same basic cover design can be adapted to fit various scope diameters and shapes (round, oval, flat-top) by simply adjusting the elastic cord tension, thereby achieving versatility without increasing design complexity.
Solution Approach 2:
The system achieves versatility by changing the physical parameters of the attachment mechanism (elastic cord tension, cord length) rather than redesigning the entire cover system for each scope size. This parameter adjustment approach maintains design simplicity while enabling compatibility with multiple scope sizes and configurations.
4Adaptability or versatility
If loose-fitting covers are used to accommodate multiple scope sizes, then adaptability is improved, but protection against moisture and debris is worsened
Solution Approach 1:
The elastic cord acts as a flexible sealing mechanism that conforms to the scope tube surface while maintaining a tight fit. This flexible attachment method provides both adaptability to different scope sizes and effective sealing against moisture and debris, resolving the contradiction between versatility and protection.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and effective protection and customization of scope lenses across various conditions and sizes, maintaining clear visibility and preventing moisture ingress.
Implementation Method 1
Between the pair of lens covers is attached a plurality of elastic cords or similar materials that hold the lens covers tightly against both ends of a scope tube in order to provide a press fit that keeps moisture, debris, etc. from entering the space between the lens covers and the scope lenses.

AI summary
An interchangeable scope lens covers system comprises a pair of lens covers each comprising a lens cover sleeve that is generally shaped like a hollow cylinder having a generally decreasing diameter from a proximal end to a distal end. Near the distal end, a generally annular lens is removably secured by a lens cap. The lenses are therefore easily removed and interchanged as desired by the user to configure the system to respond to changing shooting conditions. Between the pair of lens covers is attached a plurality of elastic cords or similar materials that hold the lens covers tightly against both ends of a scope tube in order to provide a press fit that keeps moisture, debris, etc. from entering the space between the lens covers and the scope lenses. The press fit forms a seal or barrier between the lens covers and the scope.
