Binocular Interpupillary Distance Adjustment with Sensor Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing binoculars lack an efficient method for users to easily and accurately adjust the interpupillary distance, leading to suboptimal viewing experiences and potential user fatigue due to overlapping image circles when the distance is not properly set.
Innovation Solution
A device and method that includes a detection system using sensors to determine the current interpupillary distance and provide visual, tactile, and acoustic feedback to help users adjust it to the optimal setting, utilizing trigonometric calculations or an allocation table to calculate the distance based on the folding angle of the binoculars' folding bridge.

Engineering Contradiction Analysis
1Volume of moving object
If the binoculars are folded to minimum housing dimensions for transport, then the housing dimensions are reduced, but the interpupillary distance is adjusted to a minimum and no longer corresponds to the optimal interpupillary distance of the user
Solution Approach 1:
The system performs preliminary action by automatically detecting the user's interpupillary distance and storing it in memory before use. When the binoculars are unfolded, the system automatically restores the saved interpupillary distance setting, eliminating the need for manual adjustment and ensuring optimal viewing distance is achieved quickly and comfortably
2Ease of operation
If the user manually adjusts the interpupillary distance by pivoting the housing halves, then the optimal viewing distance can be achieved, but the adjustment process is time-consuming and lacks precise feedback
Solution Approach 1:
The system introduces feedback by using a detection device (such as a sensor) to continuously monitor the actual interpupillary distance during adjustment. This real-time feedback information is processed and displayed to the user, enabling precise control and quick identification of the optimal setting, significantly reducing adjustment time compared to manual trial-and-error methods
3Device complexity
If no detection device is used, then the device complexity is reduced, but the user cannot easily determine when the optimal interpupillary distance is reached
Solution Approach 1:
The detection device provides quantitative feedback on the actual interpupillary distance, displaying it to the user so they can easily identify when the optimal distance is reached. This eliminates guesswork and significantly improves ease of operation
Solution Approach 2:
The system replaces manual mechanical adjustment and estimation with an automated detection and display system. The detection device electronically measures the interpupillary distance and presents this information to the user, substituting the need for complex manual measurement and estimation processes
