Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the reticle illumination is adjusted based on ambient light conditions at the aiming device, then the reticle brightness can be regulated, but the illumination may not match the target's light conditions leading to aiming inaccuracies
Solution Approach 1:
The patent introduces a light sensor arrangement with a lens and detector as an intermediary system to measure light conditions at the target area. The lens focuses light from the target area onto the detector, enabling indirect measurement of target illumination conditions without direct contact. This intermediary measurement system resolves the contradiction by providing accurate target light condition data while maintaining reticle illumination control.
Solution Approach 2:
The patent replaces mechanical or direct optical measurement systems with an electronic light sensor arrangement. Instead of using complex mechanical optical instruments to measure target illumination, the system uses a semiconductor-based detector with lens focusing, enabling precise electronic detection of light conditions at the target area and feeding this information back to control reticle illumination.
2Measurement precision
If a light sensor arrangement with lens and detector is added to measure target light conditions, then reticle illumination accuracy improves, but device complexity increases
Solution Approach 1:
The light sensor arrangement serves multiple functions: the lens focuses light from the target area, the detector measures light intensity, and together they provide feedback for reticle illumination control. This multi-functional arrangement achieves precise target light condition measurement while minimizing the number of separate components needed, thereby reducing overall device complexity.
Solution Approach 2:
The patent changes the operational parameters of existing components to achieve the desired function. The lens is positioned and sized to focus light from a specific target area onto the detector, and the detector is calibrated to measure light intensity within a predetermined area. By optimizing these parameters, the system achieves accurate measurement with minimal added complexity.
