Adjustable Binoculars with Multi-Axis Optical Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable binocular devices lack customization to fit individual users' interpupillary distance, eye relief, and viewing angles, limiting comfort and effectiveness in applications like virtual reality and FPV drone goggles.
Innovation Solution
A hands-free binocular device with an adjustable frame that fits to the wearer's head, featuring laterally, vertically, and longitudinally adjustable telescope sections, along with independent eyepiece rotation, to accommodate unique interpupillary distances and eye relief, and includes a spring-biased temporal bone support and ratcheting rear support system for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed binocular device is used, then the structure is simple and easy to manufacture, but it cannot be adjusted to fit different users' interpupillary distance, eye relief, and viewing angles
Solution Approach 1:
The binocular device is divided into multiple independently adjustable components: the telescope assembly can be adjusted laterally for interpupillary distance, vertically for viewing angle, and longitudinally for eye relief. Each component can be adjusted separately to accommodate different user requirements without affecting other parameters.
Solution Approach 2:
The device incorporates dynamic adjustment mechanisms that allow the user to modify the binocular parameters in real-time. The telescope assembly can be moved along multiple axes, and the adjustment mechanisms remain engaged during use, enabling continuous adaptation to different viewing conditions and user preferences.
2Ease of operation
If multiple adjustment mechanisms are added to customize the binocular device, then user comfort and fit are improved, but the device complexity and difficulty of operation increase
Solution Approach 1:
Multiple adjustment functions are integrated into a unified telescope assembly structure. The lateral adjustment for interpupillary distance, vertical adjustment for viewing angle, and longitudinal adjustment for eye relief are combined into a single cohesive mechanism that moves the telescope assembly as one unit, reducing the number of separate adjustment components needed.
Solution Approach 2:
The adjustment mechanisms are designed to serve multiple functions simultaneously. For example, the lateral adjustment mechanism not only changes the interpupillary distance but also maintains proper alignment of the optical path. The vertical adjustment mechanism adjusts both the viewing angle and the position of the exit pupil, reducing the need for separate adjustment systems.

AI summary
A binocular device that is wearable on the head of the user or wearer and does not require any hands to hold in place. The device has a pair of telescope sections that transmit an image to an eyepiece viewable by a wearer. Each eyepiece can be adjusted laterally to conform to the wearer's interpupillary distance; vertically, preferably vertically in an arc to provide a desired viewing angle; and longitudinally in relation to the wearer's eyes to a desired eye relief; the adjustments providing a custom-fit device.
