Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional volumetric display technology is used to display three-dimensional images, then the display can show volumetric images from multiple directions, but the image orientation cannot be dynamically adjusted in response to external real-world object movements
Solution Approach 1:
The patent applies dynamics by making the image orientation adjustable and responsive to external real-world object movements. The display system transitions from a static fixed-orientation volumetric display to a dynamic system where the three-dimensional image orientation changes in response to detected object positions and movements, enabling adaptability to viewer movements while maintaining ease of operation through automated sensing and reorientation
Solution Approach 2:
The patent implements feedback by using sensors to detect the position and movement of external real-world objects, then using this detected information to dynamically adjust and reorient the three-dimensional image orientation. This closed-loop feedback system allows the display to respond to viewer movements and interactions, simultaneously improving adaptability and interactive user experience
2Adaptability or versatility
If the display system dynamically reorients three-dimensional images in response to external objects, then interactivity and adaptability are enhanced, but the device complexity increases due to additional sensors and processing requirements
Solution Approach 1:
The patent applies universality by designing a system where the display plate serves multiple functions: it both displays the volumetric three-dimensional image and acts as a sensing element to detect external real-world objects. The same display structure that presents visual information also contributes to detecting object positions and movements, reducing the need for separate dedicated sensing components and thereby limiting the increase in device complexity

AI summary
A method of dynamically displaying a three-dimensional image object in a volumetric display apparatus is provided. The method includes rotating a display plate about an axis to display a volumetric three-dimensional image; displaying a first three-dimensional image of a first three-dimensional image object according to first coordinates in a first image coordinate system in the volumetric display region; sensing a position or a movement of an external real-world object within a sensing zone; and displaying a second three-dimensional image of a second three-dimensional image object according to second coordinates in a second image coordinate system in the volumetric display region. The second three-dimensional image object is obtained by reorienting the first three-dimensional image object from an initial orientation to a target orientation; and the reorientation is correlated with a position or the movement of the external real-world object.
