Telescopic Sight Reticle Adjustment Device with Displacing Index Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustment devices for telescopic sight reticles often cause confusion between multiple sets of scale values, leading to potential errors in setting the correct shooting distance due to the simultaneous visibility of scale values during different rotation ranges.
Innovation Solution
The adjustment device features a vertically displacing index ring or aperture ring that covers and uncovers scale values as the adjustment cap rotates, ensuring only one set of scale values is visible at a time, enhancing clarity and reducing errors by hiding the irrelevant set during the transition from the first to the second rotation range.

Engineering Contradiction Analysis
1Loss of information
If both sets of scale values are always visible on the adjustment device, then the user can see all available scale values at all times, but confusion arises between the two scale values leading to potential errors in setting the correct shooting distance
Solution Approach 1:
The patent extracts and separates the two sets of scale values into different rotational positions. The first set of scale values is associated with the first rotational position of the adjustment cap, while the second set is associated with the second rotational position. This extraction ensures that only the relevant scale values are visible at any given time, eliminating confusion and preventing errors in setting the correct shooting distance.
Solution Approach 2:
The patent implements a dynamic display system where the visibility of scale values changes based on the rotational position of the adjustment cap. As the user rotates the adjustment cap between 0° and 360°, the scale values dynamically switch between the first set and the second set. This dynamic behavior ensures that the appropriate scale values are always visible and relevant to the current adjustment range.
2Measurement precision
If the adjustment cap rotates more than one full revolution (approximately two full revolutions) to ensure sensitive adjustment, then the adjustment precision is improved, but the complexity of reading and interpreting scale values increases
Solution Approach 1:
The patent segments the rotational range into distinct positions: the first rotational position (0°-360°) displays the first set of scale values, and the second rotational position (360°-720°) displays the second set of scale values. This segmentation simplifies the reading process by presenting only one set of scale values at a time, making it easier for users to interpret the correct adjustment value even when the adjustment cap rotates more than one full revolution.
Solution Approach 2:
The patent introduces an intermediary mechanism (the adjustable display element) that mediates between the rotation of the adjustment cap and the display of scale values. This intermediary ensures that the appropriate scale values are displayed based on the current rotational position, simplifying the user's task of reading and interpreting the scale values during multi-revolution adjustments.
