Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a conventional display is equipped on a wearable electronic apparatus, then the apparatus can display information, but the display area is limited due to the size constraints of the wearable device
Solution Approach 1:
The patent introduces an optical system comprising a display unit, light path converting component, and lens as an intermediary between the small display component and the user's eye. This optical intermediary magnifies the image formed by the small display component, enabling a large display area without increasing the physical size of the wearable apparatus.
Solution Approach 2:
The patent transitions from a direct 2D display surface to a 3D virtual image space. By using the light path converting component and lens to create a magnified virtual image that can be viewed at a distance, the display effectively extends into the third dimension (space), providing a large display area without increasing the physical footprint of the device.
2Area of stationary object
If the display area is increased using optical magnification, then larger images can be displayed, but the system complexity increases due to additional optical components
Solution Approach 1:
The fixing body is designed to serve multiple functions: it secures the wearable apparatus to the user, positions the optical components relative to the user's eye, and may incorporate sensors for detecting viewing distance and angle. This multi-functionality reduces the need for separate components, thereby managing system complexity while achieving large display area.
Solution Approach 2:
The patent incorporates sensors that dynamically detect the user's viewing distance and angle, and the processing unit dynamically adjusts the displayed image based on these parameters. This dynamic adaptation allows the system to optimize performance for different viewing conditions without requiring complex mechanical adjustment mechanisms, thus managing complexity while maintaining large display area.
3Adaptability or versatility
If a fixed display content is provided, then the display structure is simple, but the user experience deteriorates when the viewer is at different viewing distances
Solution Approach 1:
The patent implements a feedback mechanism where sensors detect the user's viewing distance and angle, and this information is fed back to the processing unit. The processing unit then adjusts the displayed image accordingly, creating a closed-loop system that adapts to the user's viewing conditions. This feedback mechanism enables adaptability to different viewing distances without requiring overly complex manual adjustment systems.
Solution Approach 2:
The system performs preliminary detection of viewing distance and angle before rendering the final image. The processing unit pre-adjusts the display content based on detected parameters, ensuring the image is optimized for the user's viewing position before presentation. This preliminary action simplifies the real-time adjustment process and improves user experience across different viewing distances.
4Manufacturing precision
If a small display component is used, then the wearable apparatus can remain compact, but the image resolution and quality are limited
Solution Approach 1:
The patent creates a virtual copy or replica of the image at a larger scale using the optical system. The small display component generates an image that is then magnified by the light path converting component and lens to form a larger virtual image in space. This optical copying allows high-resolution imaging from a small component, as the resolution is preserved while the apparent size is increased.

AI summary
An electronic apparatus includes a main body, a fixing body, and a first display unit provided on the main body and/or the fixing body, wherein the first display unit has a first visible area and when the eyes of the viewer are a first distance away from the first visible area, a first image area of the image is perceived by the viewer, and when the eyes of the viewer are a second distance away from the first visible area, a second image area of the image is perceived by the viewer. The second image area includes the first image area and the first distance is larger than the second distance. A first content in the first image is displayed in the first image area, wherein the first content is perceived by the viewer when eyes of the viewer are the first distance away from the first visible area.
