Archery Peep Sight Removable Lens Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing archery peep sights face difficulties in changing lenses without complete disassembly, risking lens loss, and require complex disassembly for cleaning, which is impractical in the field due to exposure to weather and mechanical locking mechanisms.
Innovation Solution
The archery bow peep sight features a barrel with internal threads and a locking channel, a front peep shade cap with a knurled grip, a lens seat with a frustoconical inner wall, and a rear aperture with flexible L-shaped retainers, allowing for easy lens removal, cleaning, and replacement without tools, while maintaining secure attachment to the bowstring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lenses are mechanically locked into place within the peep, then lens security is improved, but device complexity increases and lens replacement becomes difficult
Solution Approach 1:
The peep sight is divided into separable components: a barrel assembly that remains on the bowstring and a lens assembly that can be independently removed. The lens is held by flexible retainers within the lens assembly, allowing the lens to be accessed and replaced without disassembling the entire peep sight or risking loss of components.
2Ease of operation
If lenses are held by mechanical threads, then lens replacement is easy, but lenses may fall out or be dropped during change
Solution Approach 1:
The lens is nested within a lens assembly that includes flexible retainers and a retaining structure. The lens assembly itself is nested within the barrel assembly. This nested configuration allows the lens to be securely held by the flexible retainers while the entire lens assembly can be easily removed from the barrel for lens replacement without risk of the lens falling out.
3Ease of repair
If complete disassembly is required to clean lenses, then cleaning access is improved, but lens loss risk increases and operation becomes complex
Solution Approach 1:
The peep sight is segmented into a barrel assembly and a removable lens assembly. The lens assembly can be completely removed from the barrel assembly by simply pulling it outward, providing full access to the lens for cleaning without requiring disassembly of the barrel or other components. This segmentation allows the lens to be cleaned while secured in the lens assembly, eliminating lens loss risk.
4Stability of the object's composition
If the peep sight is secured to the bowstring, then stability is improved, but lens cleaning and replacement becomes impractical in the field
Solution Approach 1:
The peep sight is divided into a barrel assembly that remains secured to the bowstring and a separate lens assembly that can be independently removed. This allows the peep sight to remain stable on the bowstring while the lens assembly can be easily accessed, removed, and maintained in the field without requiring the archer to disassemble or remove the entire peep sight from the bowstring.

AI summary
Archery bow peep sight for an archery bow string having barrel with an internal hollow passage therethrough. The inner passage has internal front threads, internal rear threads and an intermediate section locking channel. A lens seat with outer annular retainer, a top lens support ring and a frustoconical inner wall is lowered into and locked into the intermediate section locking channel of the barrel. A front peep shade cap with outer threads and a knurled finger grip is threadable into the internal front barrel threads and has a frustoconical inner wall. A rear aperture has outer threads threadable into the internal rear threads of the barrel and a knurled finger grip. The aperture has a frustoconical inner wall and a lower lens cavity whereat a lens is seated. Lowermost flexible lens retainers, that are generally L-shaped, hold the lens within the lens cavity.
