Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional two-way video communication system is used with separate video monitors and cameras at each location, then video communication functionality is achieved, but the system becomes large and fixed in location
Solution Approach 1:
The patent combines the display device and image capture device into a single integrated portable unit. The display shows images captured by the same device, eliminating the need for separate monitors and cameras at each location. This merging enables portability while maintaining two-way video communication functionality through a unified handheld system.
2Ease of operation
If the image capture device is positioned at the edge of the display, then the system structure is simplified, but the capture angle becomes poor and image quality deteriorates
Solution Approach 1:
The patent makes the image capture device rotatable relative to the display, allowing dynamic adjustment of the capture angle. The capture device can be rotated to different positions to achieve optimal shooting angles for various scenarios, transforming a static edge-positioned camera into a dynamically adjustable capture system that adapts to different operational needs.
3Ease of operation
If the display is held in one hand during video communication, then portability is maintained, but image shake occurs due to hand motion
Solution Approach 1:
The patent replaces mechanical image stabilization mechanisms with a software-based solution. The processor detects hand shake through image analysis and compensates for it by adjusting and modifying the captured images digitally. This substitution of mechanical stabilization with computational methods maintains image stability while keeping the device structure simple and portable.
4Ease of operation
If the capture device is positioned at the edge of the display, then device structure is simplified, but privacy and security control becomes difficult
Solution Approach 1:
The patent extracts the privacy control functionality as a separate operational mode that can be activated independently. When privacy mode is enabled, the system automatically processes images to blur or obscure backgrounds, separating the privacy control feature from the basic capture function. This allows users to easily enable or disable privacy controls without adding complex physical mechanisms.

AI summary
A method and device for adapting a display image on a hand-held portable wireless display and digital capture device. The device includes a camera for capturing a digital video and/or still image of a user, means for adjusting the captured digital image in response to poor image capture angle of said image capture device so as to create a modified captured digital image; and means for transmitting said modified captured digital image over a wireless communication network to a second hand-held portable wireless display and digital capture device.
