Solution Overview
Problem
Current Mixed Reality (MR) products lack the conventional glasses function and provide poor usefulness due to complex structures that strip off essential functionalities, and they fail to achieve stereo superposition of real and virtual reality.
Innovation Solution
Smart eyeglasses with a support, display assembly, image acquisition module, and processing control module that acquire and process depth information to superimpose virtual scenes onto real scenes through a transparent display screen, allowing both conventional glasses and MR functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional glasses are modified to add mixed reality functions, then mixed reality capability is improved, but device complexity increases and conventional glasses function deteriorates
Solution Approach 1:
The patent implements multi-functionality by integrating both conventional glasses functionality and mixed reality capabilities into a single device. The frame structure serves dual purposes: supporting traditional glasses components (lenses, temples, nose pads) while also mounting MR components (image acquisition module, display assembly, processing module). This allows the device to function as both regular glasses and an MR headset, resolving the contradiction between adding MR capability and maintaining conventional function.
Solution Approach 2:
The patent divides the device into functionally independent modules: a support (frame), a display assembly, an image acquisition module, and a processing control module. Each module can be independently designed, manufactured, and adjusted. The display assembly includes separate lens and transparent display screen components that can be independently optimized. This modular segmentation reduces overall device complexity by allowing independent development and optimization of each functional component.
2Adaptability or versatility
If conventional glasses are modified to add mixed reality functions, then mixed reality capability is improved, but conventional glasses function deteriorates
Solution Approach 1:
The frame structure is designed to universally support both conventional glasses components and MR components. The temples, frame front, and nose pads maintain their traditional functions for wearing comfort and structural support, while simultaneously providing mounting structures for MR components. This ensures that conventional glasses functionality is preserved and maintained alongside MR capabilities.
Solution Approach 2:
The processing control module acts as an intermediary that manages both conventional glasses operations and MR functions. It receives input from the image acquisition module, processes the captured images, and controls the display assembly to present virtual content. This intermediary control system ensures that both conventional and MR functions operate reliably without interfering with each other, maintaining the reliability of conventional glasses function while enabling MR capabilities.
3Adaptability or versatility
If depth information is acquired and virtual scenes are superimposed onto real scenes, then mixed reality effect is improved, but device complexity increases
Solution Approach 1:
The device is segmented into distinct functional modules: the image acquisition module captures depth information, the processing control module processes and generates virtual scene content, and the display assembly presents the superimposed result. This segmentation allows each module to be independently optimized and reduces overall system complexity by avoiding tight coupling between components.
Solution Approach 2:
The patent replaces complex mechanical optical systems with electronic and software-based solutions. Instead of using complex optical hardware to achieve stereo superposition, the system uses the image acquisition module to capture depth information, processes it through the processing control module to generate appropriate virtual content, and displays it through the transparent display screen. This substitution of mechanical/optical systems with electronic processing simplifies the overall device architecture.
