Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional binocular telescopes are cumbersome due to their large diameter during use, limiting design flexibility and ergonomics.
Innovation Solution
The binocular telescope design features a hinge bridge that allows adjustment of interpupillary distance, with optical axes in a common plane, and ergonomic recesses for finger and thumb grips, along with a compact prism system and focusing mechanism for improved comfort and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the telescope is designed with conventional optical axis arrangement, then the optical system is stable, but the overall height becomes large making it cumbersome to use
Solution Approach 1:
The patent inverts the conventional arrangement by placing the optical axes in a common plane with the hinge axis, rather than the typical configuration. This inversion allows the prism system to be positioned more compactly, reducing the overall height of the telescope while maintaining optical functionality
Solution Approach 2:
The patent redistributes components along different spatial dimensions, specifically arranging the optical axes and hinge axis in a common plane. This dimensional reorganization creates more efficient space utilization, allowing the prism system to be positioned closer to the objective lens, thereby reducing the overall height without compromising optical performance
2Ease of operation
If the telescope diameter is reduced for better ergonomics, then ease of handling improves, but the optical performance and field of view may be compromised
Solution Approach 1:
The patent changes the spatial parameters of the optical system by arranging optical axes in a common plane with the hinge axis. This parameter change allows for a more compact telescope diameter while maintaining the necessary optical path length and field of view, thus improving handling ease without sacrificing optical performance
