Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If AR or VR multifunctional head-mounted devices are used to provide visual experiences, then users can receive image-related signals, but the devices cannot provide real-time image signals to both eyes simultaneously and cannot track eyeball positions effectively
Solution Approach 1:
The device is divided into independent functional modules: a first image generating module with first image generating chips for the left eye, a second image generating module with second image generating chips for the right eye, a signal control module, and a device casing module. Each module operates independently but coordinates through the signal control module, enabling real-time image projection to both eyes and eyeball tracking without excessive system complexity
Solution Approach 2:
The signal control module serves as an intermediary that receives image-related signals, processes them, and distributes them to the appropriate image generating modules. It also receives eyeball position signals from the optical waveguide channels and coordinates the projection of image beams based on tracked eyeball positions, resolving the complexity of simultaneous dual-eye projection and tracking
2Productivity
If image generating chips are arranged to surround the eyeglass lens structure, then real-time image projection to both eyes is achieved, but the device structure becomes more complex
Solution Approach 1:
The image generating chips are configured to surround the eyeglass lens structure, allowing them to perform multiple functions: generating image beams for projection onto the user's eyes and facilitating eyeball position tracking through the optical waveguide channels. This multi-functional arrangement achieves real-time projection capability while managing structural complexity through efficient spatial utilization
Solution Approach 2:
The image generating chips are arranged in a three-dimensional configuration surrounding the lens structure rather than a simple planar arrangement. This spatial distribution allows optimal positioning for image beam projection while maintaining compact integration within the head-mounted device framework
