Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a camera is located on the top of the smartphone, then the device can capture images for display, but the user's gaze direction becomes mismatched (looking at the front display while the camera captures from above)
Solution Approach 1:
The patent combines the image sensing element with the display panel by integrating multiple image sensing elements between the display pixels, creating a unified structure that eliminates the need for separate camera modules and resolves the gaze mismatch problem
2Area of stationary object
If a camera is arranged on the top of the smartphone, then image capture is enabled, but it requires additional space and limits the implementation of bezel-less full screen displays
Solution Approach 1:
The patent merges the camera functionality into the display panel itself by integrating image sensing elements within the panel structure, eliminating the need for separate camera modules and enabling bezel-less full screen designs
Solution Approach 2:
The display panel serves dual functions as both a display device and an image sensing device, with the integrated image sensing elements enabling photographing functions within the same structural framework
3Ease of operation
If multiple image sensing elements are integrated within the panel device, then gaze mismatch is reduced and bezel-less display is enabled, but the field of view of each sensing element needs to be precisely adjusted
Solution Approach 1:
The patent employs a viewing zone adjusting assembly with liquid crystal shutters that can dynamically change the field of view of each image sensing element by controlling light transmission, allowing flexible adjustment of viewing zones to optimize user interaction
Solution Approach 2:
The patent introduces a viewing zone adjusting assembly as an intermediary component between the optical element and image sensing elements, using liquid crystal shutters to mediate and control the field of view for each sensing element
