Telescopic Sight Adjustment Aid for Tactile Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rifle scopes are difficult to adjust precisely, especially in wet and cold conditions, and require visual contact, making it challenging to operate adjustment wheels with multiple settings quickly and accurately.
Innovation Solution
A rifle scope design featuring an adjusting wheel with a radially protruding adjustment aid that can be easily felt and operated without visual contact, allowing for precise adjustments and detachable for optional use, along with a coupling mechanism providing multiple mounting positions and ergonomic design for comfortable handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If adjustment wheels with multiple settings and scales are provided, then adjustment precision is improved, but ease of operation deteriorates in wet and cold conditions
Solution Approach 1:
A tactile indicator element is introduced as an intermediary between the adjustment wheel and the user's finger. This element protrudes radially from the adjustment wheel's outer circumference and provides a distinct tactile reference point that can be easily felt and positioned even with wet or cold fingers, thereby improving ease of operation without compromising adjustment precision
Solution Approach 2:
The patent applies the principle of sensory change by making the indicator element visually distinct through color or reflective properties. The indicator can be seen against the background of the adjustment wheel, allowing users to quickly identify its position without visual contact with the target, thus improving both ease of operation and adjustment precision
2Measurement precision
If adjustment wheels with scales are provided, then adjustment precision is improved, but ease of operation deteriorates as visual contact is required
Solution Approach 1:
The tactile indicator element serves as a mediator that translates the rotational position of the adjustment wheel into a formable tactile signal. Users can feel the position of this element with their fingers and make precise adjustments without needing to visually check the scale, eliminating the need for visual contact while maintaining adjustment precision
Solution Approach 2:
The patent replaces the visual-mechanical reading system (scales requiring visual contact) with a tactile-mechanical system. The indicator element provides mechanical feedback through touch, allowing users to sense rotational position and make precise adjustments through tactile sensation alone, thereby improving ease of operation without sacrificing precision
3Ease of operation
If adjustment wheels with textured surfaces are provided, then ease of operation is improved, but adjustment precision deteriorates due to difficulty in reading settings
Solution Approach 1:
The adjustment wheel is designed with differentiated local qualities: the outer circumference has a textured surface for enhanced grip and ease of operation, while the radially protruding indicator element provides a smooth, distinct tactile reference point for precise positioning. This local differentiation allows users to easily rotate the wheel while accurately determining its angular position, thereby maintaining both ease of operation and adjustment precision
