Archery Sight Weather Protection via Sealed Lens Chamber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing archery scopes and sights lack effective protection from precipitation, such as rain, snow, and fog, which can reduce sighting precision by allowing elements to enter from all directions, unlike previous solutions that either provide inadequate protection or increase the device's profile.
Innovation Solution
A cylindrical archery scope with clear or tinted front and back lenses that encase a sight fiber, forming a sealed chamber to prevent external elements from entering while maintaining visibility for sighting, using a mounting block and threaded screw arrangement for adjustable attachment to a bow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a hood-like cover is used to protect the sight from precipitation, then protection from precipitation is improved, but the overall profile of the sight increases and side protection is insufficient
Solution Approach 1:
The patent applies a cylindrical lens assembly that acts as a protective shell enclosing the sight fiber. This cylindrical structure provides 360-degree protection from precipitation while maintaining a compact, low-profile design. The lens assembly functions as both a protective barrier and an optical element, eliminating the need for external hood-like covers that would increase the sight's profile.
2Device complexity
If the sight fiber is exposed to ambient conditions, then the sight structure remains simple, but precipitation enters from all directions and reduces sighting precision
Solution Approach 1:
The cylindrical lens assembly serves multiple functions simultaneously: it protects the sight fiber from precipitation entering from all directions, maintains structural simplicity, and provides optical functionality. This multi-functional design prevents precipitation contamination while keeping the overall structure compact and simple, without requiring separate protective housings or complex sealing mechanisms.
3Object-affected harmful factors
If lenses are added to encase the sight fiber, then protection from precipitation is improved, but the device complexity increases
Solution Approach 1:
The patent merges the protective function and the optical function into a single integrated component. The cylindrical lens assembly combines the role of a protective enclosure with the role of an optical element, eliminating the need for separate protective housings, seals, and mounting structures. This integration reduces device complexity while providing comprehensive protection from precipitation.
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
The solution provides low-profile, all-directional protection from precipitation, ensuring precise sighting by keeping the interior of the scope and sight fiber isolated from external elements, enhancing performance in adverse weather conditions.
Implementation Method 1
Two lenses, one affixed to a front end of the cylindrical sight body and a second affixed to back end of the cylindrical sight body... The lenses keep precipitation from getting into the chamber formed by the cylinder capped at both ends by the lenses
Data Source
AI summary
An archery sight includes a cylindrical sight body which is open at both ends prior to assembly and has a longitudinal axis. Two lenses, one affixed to a front end of the cylindrical sight body and a second affixed to back end of the cylindrical sight body are clear (or can be tinted, as long as they can be seen through), hold a sight fiber in place between the two lenses. In this manner, the interior of the cylindrical sight body and the fiber situated within the interior and extending along its longitudinal axis are essentially sealed off from the elements but can still perform their sighting function. The lenses keep precipitation from getting into the chamber formed by the cylinder capped at both ends by the lenses.
