Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If fluorescent-doped optical fibers are used to create multiple sight points, then the sight points are bright and visible, but all sight points have uniform brightness making it difficult to distinguish the correct sight point for different distances
Solution Approach 1:
The patent applies local quality by making each optical fiber segment have different fluorescent dopant concentrations or types, causing different emission wavelengths or intensities at different positions along the fiber. This allows each sight point to have distinct local characteristics that encode distance information while maintaining brightness.
Solution Approach 2:
The patent utilizes color changes by employing fluorescent dopants that emit different wavelengths (colors) of light at different positions along the optical fiber. This enables the archer to distinguish between sight points for different distances based on the color or wavelength of light emitted, while all points remain equally bright.
2Illumination intensity
If the sight pin is made thick to improve visibility, then the sight point is more visible, but it blocks the impact zone of distant targets
Solution Approach 1:
The patent applies segmentation by dividing the sight pin into multiple discrete optical fiber segments or using a thin optical fiber with reflective elements. This segmentation allows the sight point to be visible without requiring a thick continuous pin, thereby reducing blockage of the target impact zone while maintaining visibility through the segmented structure.
3Adaptability or versatility
If the entire sight assembly is replaced to change the sight pin, then the correct sight pin can be selected, but the process is labor-intensive and impractical in the field
Solution Approach 1:
The patent applies segmentation by making the sight pin a separate, modular component that can be independently removed and replaced without replacing the entire sight assembly. This allows the archer to quickly swap between different sight pin configurations (different lengths, thicknesses, or optical properties) by simply detaching and reattaching the pin component, making field adjustment practical and efficient.
Solution Approach 2:
The patent applies dynamics by designing the sight pin with a mechanism that allows for quick adjustment and replacement in the field. This may include threaded adjustments, bayonet-style attachments, or spring-loaded mechanisms that enable the sight pin to be dynamically changed without tools or complex procedures, adapting to different shooting conditions quickly.
4Ease of manufacture
If the sight window is fixed during manufacturing, then manufacturing is simpler, but alignment with the line of sight and bow riser is prone to errors from bumps and tolerance variations
Solution Approach 1:
The patent applies dynamics by making the sight window adjustable rather than fixed. This allows the sight window to be positioned and aligned precisely after the bow has been assembled, compensating for tolerance variations and any shifts that may occur during field use. The adjustable mechanism enables realignment of the sight window with the line of sight and bow riser, maintaining manufacturing precision while keeping the manufacturing process relatively simple.

AI summary
A selective sight assembly for a sighting device associated with an archery bow or similar devices, has a frame portion defining a sight window and a sight portion connectable to the frame portion. The sight portion includes a sight pin connectable to the frame portion and a light conduit connected to the sight pin for movement therewith. The light conduit has a first light coupling end and a second light transmitting end that defines a sight point for view by a user. A plurality of light collectors are provided, with each light collector having a second light coupling end for selective optical coupling with the first light coupling end. Movement between the light conduit and the light collectors causes optical coupling between the first light coupling end and one of the second light coupling ends. The frame portion is rotatable about three mutually perpendicular axes to enable tuning of the selective sight assembly for a particular archery bow configuration.
