Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional two-dimensional display technology is used, then the display structure is simple and easy to manufacture, but the ability to exhibit three-dimensional shapes and orientations is lost
Solution Approach 1:
The display device uses deformable cells that can dynamically change their physical shape in response to control signals. Each cell can expand, contract, bend, or twist to create three-dimensional surface variations, allowing the display to transition from a flat two-dimensional state to a three-dimensional form without requiring a permanently complex structure
Solution Approach 2:
The invention changes the physical parameters of the display cells by controlling their deformation through electrical signals. By adjusting parameters such as cell volume, curvature, and relative position, the display can exhibit three-dimensional shapes while maintaining a relatively simple base structure that only becomes complex when actively deformed
2Illumination intensity
If three-dimensional display technology is used to exhibit all aspects of objects, then visual sensation is improved, but tactile sensation of real touch is still lacking
Solution Approach 1:
The display device creates physical copies of three-dimensional objects by deforming an array of cells to match the target object's shape, texture, and surface features. These cellular structures can be touched and manipulated, providing genuine tactile feedback while visually representing the target object, thus copying both its visual and tactile properties
Solution Approach 2:
The display uses flexible cellular structures that can deform to create touchable three-dimensional surfaces. These flexible cells can be pressed, pinched, or stroked by users, providing authentic tactile sensations including pressure, texture, and temperature, while thin film technologies enable color and transparency changes to enhance visual realism
3Ease of operation
If cells are deformed to form three-dimensional objects, then real touch sensation is achieved, but the complexity of controlling deformation and color changes increases
Solution Approach 1:
The display is divided into numerous independent controllable cells, each capable of individual deformation and color change. This segmentation allows the complex task of creating a three-dimensional object to be distributed across many simple units, each responding to localized control signals, thereby managing overall system complexity through modular organization
Solution Approach 2:
Each display cell is designed to perform multiple functions: it can deform in various directions, change color, and adjust transparency. This multi-functionality reduces the need for separate specialized components for each function, simplifying the overall control architecture while achieving complex three-dimensional and tactile effects through a unified cellular structure
