Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional binocular Near-Eye Displays (NEDs) provide sub-optimal user comfort due to their rigid construction, which is necessary for maintaining image alignment but restricts flexibility and adaptability to the user's face shape and size.
Innovation Solution
A binocular near-eye display system with flexible coupling of displays and the use of motion sensors and image capture devices to continuously adjust content alignment in real-time, allowing for changes in orientation and accommodating varying interpupillary distances, thereby maintaining optimal image alignment without the need for robust structural support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If robust rigid structural support is used to maintain display alignment, then image alignment stability is improved, but user comfort and adaptability to different face shapes deteriorates
Solution Approach 1:
The patent applies the dynamics principle by implementing a flexible mounting structure that allows the displays to move relative to each other, coupled with motion sensors that detect orientation changes and a controller that adjusts content display in real-time to compensate for misalignment. This dynamic system replaces the static rigid structure, maintaining image alignment stability while adapting to different user face shapes and sizes.
Solution Approach 2:
The patent implements feedback by using motion sensors to continuously monitor the orientation and position of displays, feeding this information to a controller that automatically adjusts the content alignment. This closed-loop feedback system ensures image alignment is maintained dynamically without requiring rigid structural support, thereby improving both stability and adaptability.
2Ease of manufacture
If rigid construction is used to maintain alignment, then manufacturing simplicity is improved, but device complexity increases due to additional motion sensors and control systems
Solution Approach 1:
The patent replaces the mechanical rigid structure with a flexible mounting system combined with electronic sensing and control. Instead of using complex rigid mechanical assemblies to maintain alignment, the system uses motion sensors and digital content adjustment, substituting mechanical complexity with electronic control that is easier to manufacture and adjust.
3Adaptability or versatility
If flexible coupling is used to improve user comfort, then adaptability to different face shapes is improved, but image alignment stability deteriorates
Solution Approach 1:
The flexible coupling is paired with motion sensors that detect any misalignment caused by the flexibility, and a controller that compensates by adjusting the content alignment in real-time. This feedback mechanism ensures that while the structure remains flexible and adaptable, image alignment stability is maintained through active correction.
Solution Approach 2:
The system uses dynamic adjustment of content alignment based on real-time detection of display orientation changes. The flexible structure allows movement for adaptability, while the dynamic content adjustment maintains alignment stability, resolving the contradiction between flexibility and stability.
