Target Dot Sight Brightness Control Using Target Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic brightness adjustment systems in target dot sights fail to account for the brightness level of the target itself, leading to the target dot becoming invisible when the target is brighter than the ambient light sensor detects, especially in environments with varying lighting conditions.
Innovation Solution
Incorporating a target illumination sensor within a recessed design to measure the target's brightness independently of ambient light, combined with a brightness control system that adjusts the target dot's brightness based on target illumination readings, allowing for intelligent compensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an ambient light sensor is used to automatically adjust the target dot brightness, then the brightness can be adjusted based on environmental lighting conditions, but the target dot becomes invisible when the target itself is brighter than the ambient light detected
Solution Approach 1:
The patent introduces a target illumination sensor as an intermediary device that specifically measures the light intensity at the target location. This sensor acts as a mediator between the ambient light conditions and the target dot brightness control, providing accurate target-specific illumination data to the brightness control system, thereby resolving the contradiction between automatic adjustment and reliable visibility.
2Use of energy by moving object
If the target dot brightness is reduced in dark conditions, then energy consumption is reduced and comfort is improved, but the target dot becomes invisible against a brightly lit target
Solution Approach 1:
The patent implements a feedback mechanism where the target illumination sensor continuously monitors the actual light conditions at the target location and feeds this information back to the brightness control system. This closed-loop feedback ensures that the target dot brightness is dynamically adjusted based on real-time target illumination data, maintaining visibility while optimizing energy consumption.
3Device complexity
If a single static brightness setting is used, then the device complexity is reduced, but the target dot visibility varies significantly in different lighting conditions
Solution Approach 1:
The patent enables the brightness control system to automatically adjust the target dot brightness without requiring manual user intervention. The target illumination sensor and brightness control system work together in a self-service manner, where the system autonomously monitors target illumination conditions and adjusts brightness accordingly, resolving the contradiction between simplicity and adaptive visibility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures the target dot remains visible by dynamically adjusting its brightness to match the target's illumination, enhancing visibility in varying lighting conditions.
Implementation Method 1
a target illumination sensor that senses the amount of illumination at a target
Data Source
AI summary
A target dot sight includes a target illumination sensor that senses the amount of illumination at a target, rather than merely sensing the ambient sight of the entire operating environment. Then, based on the sensed target illumination, the target dot sight may automatically compensate for the brightness of the target.
