Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple depth planes are used to simulate three-dimensional imagery, then depth perception and realism are improved, but device complexity and processing burden increase
Solution Approach 1:
The waveguide assembly is divided into multiple stacked waveguides, each responsible for a specific depth plane. This segmentation allows the system to simulate three-dimensional imagery by directing light through different depths, improving depth perception accuracy while managing complexity through modular design
Solution Approach 2:
The patent transitions from two-dimensional display to three-dimensional imagery simulation by adding the depth dimension through stacked waveguides. Each waveguide layer corresponds to a different depth plane, creating a volumetric display effect that enhances realism without requiring full volumetric rendering
2Ease of operation
If image presentation is dynamically adjusted based on eye movements and pupil size, then visual comfort and realism are improved, but processing burden and energy consumption increase
Solution Approach 1:
The system incorporates sensors to detect eye movements and pupil size in real-time, using this feedback to dynamically adjust image presentation across the stacked waveguides. This feedback mechanism enhances visual comfort by aligning accommodation and vergence while optimizing energy consumption through selective rendering based on user gaze
3Measurement precision
If inward- and outward-facing imaging systems are incorporated for precise object positioning, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The patent merges inward-facing and outward-facing imaging systems into a unified wearable device architecture. Both imaging systems work together to capture real-world surroundings and virtual objects, enabling precise positioning and alignment of virtual elements with the physical environment through integrated processing
Solution Approach 2:
The imaging systems serve multiple functions: capturing environmental data for augmented reality, tracking user gaze for dynamic image adjustment, and providing depth information for three-dimensional simulation. This multi-functionality reduces the need for separate specialized components, managing complexity while enhancing positioning accuracy
