Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rifle scopes face challenges with complex mechanical adjustments for magnification and reticle settings, leading to potential errors and difficulties in reading settings in low light conditions, particularly due to the influence of magnification on reticle appearance and the need for precise calibration.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual mechanical adjustment mechanisms are used for magnification and reticle settings, then the device complexity remains low, but the ease of operation deteriorates due to difficulty in reading settings and potential for errors
Solution Approach 1:
The patent replaces manual mechanical adjustment mechanisms with an automated sensor-based system. Angle sensors detect the rotational position of adjustment rings, and a control unit automatically determines and displays the corresponding magnification and reticle settings, eliminating the need for manual reading of mechanical scales and reducing adjustment errors.
Solution Approach 2:
The patent implements feedback through angle sensors that continuously monitor the rotational position of adjustment rings and provide this information to a control unit. The control unit processes the sensor data and displays the current settings, creating a closed-loop system that provides real-time feedback to the user about the actual adjustment state.
2Reliability
If mechanical adjustment scales are provided for reading settings, then the ease of operation improves, but the reliability deteriorates in low light conditions where settings cannot be read
Solution Approach 1:
The patent replaces mechanical adjustment scales with an electronic display system. Angle sensors detect the rotational position of adjustment rings, and a control unit automatically determines and displays the corresponding magnification and reticle settings on an electronic display, ensuring settings are always readable regardless of lighting conditions.
Solution Approach 2:
The patent uses an electronic display that can emit light to show settings in various lighting conditions. The display can illuminate the setting information, ensuring visibility in low light conditions where mechanical scales would be difficult or impossible to read.
3Adaptability or versatility
If multiple adjustment components are provided for magnification and reticle settings, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The patent merges multiple adjustment components into a unified sensor-based system. Instead of separate mechanical mechanisms for magnification and reticle settings, the system uses angle sensors on adjustment rings that are mechanically coupled to both functions, with a control unit that coordinates the settings based on sensor feedback, reducing overall system complexity while maintaining adaptability.
Solution Approach 2:
The patent implements multi-functionality through a single sensor-based adjustment system that controls both magnification and reticle settings. The angle sensors and control unit serve multiple functions: detecting rotational position, determining magnification level, adjusting reticle position, and displaying settings, eliminating the need for separate dedicated mechanisms for each function.
