Weighted Dial Elevation Range Meter for Long-Range Shooting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Long-range shooting becomes increasingly difficult due to the bullet's drop caused by gravity, which is influenced by the elevation angle and atmospheric conditions, making it challenging to accurately determine the offset range distance from the target.
Innovation Solution
A weighted dial system is integrated with a firearm, allowing the dial to rotate with respect to the barrel to indicate offset range markings from multiple elevation columns, enabling users to adjust their aim based on the elevation angle and atmospheric conditions, with interchangeable range markings for different elevations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional aiming methods are used for long-range shooting, then the device complexity remains low, but the measurement precision of offset range distance deteriorates
Solution Approach 1:
The elevation range meter is divided into distinct functional segments: a weighted dial for elevation angle indication, multiple columns of range markings for different distances, and an indicator mechanism. Each segment performs a specific function, allowing complex measurement capabilities while maintaining manageable structural organization.
Solution Approach 2:
The elevation range meter serves multiple functions simultaneously: it measures elevation angle, determines range distance, and provides offset correction values. The weighted dial system universally indicates both elevation angle and corresponding range information through its mechanical configuration, eliminating the need for separate measurement devices.
2Adaptability or versatility
If multiple elevation range marking columns are provided on the weighted dial, then the adaptability to different elevations improves, but the device complexity increases
Solution Approach 1:
The weighted dial is designed to dynamically rotate and settle into position based on the elevation angle, automatically bringing the appropriate range marking column into alignment with the indicator. This dynamic mechanism allows multiple elevation ranges to be accommodated without requiring manual selection or complex switching mechanisms.
Solution Approach 2:
The weighted dial utilizes angular dimension to encode elevation information, with different rotational positions corresponding to different elevation angles. Multiple columns of range markings are arranged radially around the dial, allowing the system to represent multiple elevation ranges within a compact two-dimensional structure by exploiting the angular dimension.

Function Achieved in This Case
This system allows hunters and shooters to accurately compensate for bullet drop and atmospheric effects, ensuring precise targeting by providing clear offset range markings for various elevations and distances, enhancing accuracy in long-range shooting.
Implementation Method 1
A weighted dial has a weighted portion that will be pulled to a vertical position, or downward, regardless of the elevation angle of the firearm

AI summary
An elevation range meter is configured to be used in conjunction with a reticle to provide an offset range marking, such as an offset range distance that a target is located over on the reticle before firing. An offset range distance factors in the range to the target and the elevation of the firearm. The elevation range meter has a weighted dial that rotates with respect to the barrel or elevation angle to indicate an offset range marking, such as a distance, milliradians or minutes of angle, from a plurality of elevation range marking columns on the weighted dial. The weighted dial may have a plurality of columns of elevation range markings and the appropriate column for the determined range may be selected to indicate the offset range distance. The user may then locate the target on the reticle at this offset range distance before firing.
