Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the screen size and functionality of wearable devices are increased to match smartphones, then the device complexity and structural requirements increase, making it difficult to maintain portability and wearability
Solution Approach 1:
The display system is segmented into multiple independent display assemblies (first display assembly on the first housing, second display assembly on the second housing) that can be positioned at different locations and orientations. This segmentation allows each display to be optimized independently while collectively providing smartphone-level functionality across the wearable device structure.
Solution Approach 2:
The patent transitions from a single-plane display to a multi-dimensional display arrangement by placing displays on different housings that can be positioned at various spatial relationships (front, back, side, angled orientations). This multi-dimensional arrangement increases total display area without proportionally increasing device volume or complexity.
2Adaptability or versatility
If multiple display assemblies are positioned on different housings to increase functionality, then the optical alignment requirements for sensors and cameras become more complex
Solution Approach 1:
The optical sensors and cameras are designed with multi-functional capabilities to handle various optical paths and alignment scenarios. The sensors can detect light from multiple display assemblies and the cameras can capture images through different housing configurations, making the optical system universally adaptable rather than requiring precise alignment for each specific configuration.
Solution Approach 2:
The optical system parameters (such as field of view, focal length, and detection angles) are designed to be adjustable or variable to accommodate different display positions and orientations. This allows the optical alignment to be optimized dynamically rather than requiring fixed precise alignment, simplifying the overall system design.
