Rotatable Optical Module for Augmented Reality Glasses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality glasses require frequent removal and repositioning, causing inconvenience to users as the optical module must be taken off to avoid obstructing the view, leading to a suboptimal user experience.
Innovation Solution
The augmented reality glasses feature rotatable optical modules connected to temple brackets, allowing the optical module to move between a display position and a non-obstructive position, with adjustable mechanisms including grooves, ridges, elastic members, and fasteners to facilitate smooth rotation and secure positioning, enabling seamless transition between usage and non-usage modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the optical module is fixed in front of the lens unit for display, then the display function is improved, but the view obstruction increases
Solution Approach 1:
The optical module is made dynamically movable between a first position (in front of the lens unit for display) and a second position (deviating from the front for non-obstruction). The rotatable connection mechanism allows the optical module to transition between these positions, enabling the system to adapt its configuration based on whether display or unobstructed view is the priority.
2Object-affected harmful factors
If the optical module is removed to avoid obstruction, then the view obstruction is reduced, but the user convenience deteriorates
Solution Approach 1:
Instead of requiring complete removal of the optical module, the invention implements a dynamic rotation mechanism that allows the optical module to be repositioned to a second position where it deviates from the front of the lens unit. This dynamic adjustment eliminates view obstruction while keeping the module attached and easily repositionable when needed.
3Adaptability or versatility
If the optical module is made rotatable for position adjustment, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The connection between the optical module and the temple bracket is segmented into a rotatable joint, allowing independent movement of the optical module relative to the temple bracket. This segmentation enables position adjustment without requiring complex overall restructuring of the device.
Solution Approach 2:
The rotatable connection mechanism combines the functions of support and position adjustment into a single integrated structure. The temple bracket both supports the optical module and provides the rotation mechanism, merging multiple functions into one component to reduce overall complexity.
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
This design enhances user experience by allowing the optical module to be adjusted out of the way when not in use, preventing obstruction and reducing the need for frequent removal, while maintaining optimal display positioning, thus improving usability and adaptability.
