Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable electronic devices that provide augmented reality often suffer from increased weight due to paired optical systems and electronic components for each eye, leading to discomfort during prolonged use.
Innovation Solution
A wearable electronic device that separates images from a single display to be output to the user's left and right eyes respectively, reducing the need for duplicate optical systems and components, thereby decreasing overall weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paired optical systems and electronic components are provided for left and right eyes respectively, then augmented reality functionality is achieved, but device weight increases
Solution Approach 1:
The patent merges the optical systems for left and right eyes into a single integrated optical path. The display device projects images through one optical system that serves both eyes, eliminating the need for separate optical components for each eye while maintaining augmented reality functionality.
Solution Approach 2:
The single optical system is designed to serve multiple functions - it projects images to both the left and right eyes simultaneously, making the optical components universal rather than dedicated to a single eye. This multi-functional design reduces the total number of components required.
2Reliability
If paired displays and optical systems are used for each eye, then stereoscopic augmented reality is achieved, but wearing comfort deteriorates
Solution Approach 1:
The patent combines the display and optical systems into a unified structure that serves both eyes. By merging previously separate components into a single integrated system, the overall device size and weight are reduced, directly improving wearing comfort while maintaining stereoscopic augmented reality capability.
3Reliability
If duplicate electronic components are provided for each eye, then eye-specific augmented reality processing is achieved, but device complexity increases
Solution Approach 1:
The electronic components are designed with universal functionality to process and control images for both eyes through the single optical system. Rather than having duplicate eye-specific processing units, the system uses shared electronic components that can handle multiple functions, reducing overall device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
