Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If specialized three-dimensional glasses and equipment are used to provide a three-dimensional viewing experience, then the three-dimensional viewing experience is improved, but the device complexity and user convenience deteriorate due to requiring additional equipment
Solution Approach 1:
The patent creates a visual copy of three-dimensional depth perception on a two-dimensional screen by analyzing edge colors and generating simulated depth information. Instead of requiring actual three-dimensional equipment, the system copies the visual appearance of 3D objects through color-based edge detection and rendering, allowing users to perceive depth without wearing specialized glasses or using complex three-dimensional hardware
Solution Approach 2:
The patent replaces the mechanical/optical system of three-dimensional glasses with a software-based image processing system. By using camera capture, color analysis, and algorithmic rendering to simulate depth perception, the system substitutes complex mechanical three-dimensional display equipment with a software solution that runs on standard mobile devices
2Device complexity
If a two-dimensional touchscreen interface is used, then the device simplicity is maintained, but the tactile feedback and immersive interaction are lost
Solution Approach 1:
The patent implements tactile feedback by detecting user touch interactions with the touchscreen and providing haptic responses through a vibration motor. When a user touches the screen at locations corresponding to simulated three-dimensional objects or their edges, the system triggers appropriate vibration patterns that mimic the sensation of touching physical objects, thereby restoring tactile feedback to the two-dimensional interface
Solution Approach 2:
The patent merges visual three-dimensional rendering with tactile haptic feedback into a unified interaction system. By combining the visual simulation of depth with synchronized tactile responses, the system creates a multi-sensory experience that enhances user interaction with simulated three-dimensional objects while maintaining the simplicity of the two-dimensional touchscreen interface
3Shape
If static three-dimensional images are displayed, then the three-dimensional effect is achieved, but the real-time interaction and dynamic viewing experience are limited
Solution Approach 1:
The patent creates a dynamic three-dimensional experience by continuously analyzing user viewing angle and device orientation to adjust the rendering of simulated three-dimensional objects in real-time. As the user moves the device or changes their viewing position, the system dynamically recalculates which edges should be highlighted and adjusts the visual presentation accordingly, transforming static images into interactive, responsive three-dimensional displays

AI summary
A three dimensional user experience for mobile applications includes adjusting display of simulated three dimensional objects in real time and providing tactile feedback based on user interaction. A mobile application identifies a user viewing angle of a user and an orientation of the mobile device. An image analyze calibrates coordinates of the user with respect to the mobile device position and calculates pitch and roll elements of the simulated three dimensional objects with respect to a mobile device coordinate system. Based on rotational element, images are selected and/or rendered for display in real time. The mobile application analyzes an area of contact with a touchscreen and identify an edge of a selected simulated three dimensional object based on a color or color gradient. Based on a type of object and an edge type, tactile feedback is generated by triggering a vibration motor to execute a particular vibration pattern.
