Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional virtual 3D display apparatuses are used, then the display can show multi-dimensional virtual images, but the lifelikeness and quality of the virtual 3D images are far from satisfactory
Solution Approach 1:
The patent applies dynamics by making the optical fiber assembly movable rather than static. The assembly can rotate and change its angular position to dynamically adjust the viewing angle and light emission direction. This dynamic capability allows the system to adapt to different viewing conditions and enhance the lifelikeness of the virtual 3D images by simulating how real objects reflect light from different angles.
Solution Approach 2:
The patent changes physical parameters of the optical system by varying the angular position of the optical fiber assembly and adjusting the light emission characteristics. By changing the angle parameter and light intensity parameters, the system can control the viewing angle and image quality, thereby improving lifelikeness. The movable assembly allows continuous parameter adjustment to optimize the visual experience.
2Adaptability or versatility
If the optical fiber assembly is made movable to enhance viewing angle control, then the viewing angle can be adjusted, but the device complexity increases
Solution Approach 1:
The movable optical fiber assembly serves multiple functions: it controls the viewing angle, adjusts the light emission direction, and potentially integrates with control systems for automated operation. By making this single assembly multi-functional, the patent reduces the need for separate mechanisms for each function, thereby managing device complexity while achieving versatile viewing angle control.
3Reliability
If multiple light sources are provided at the input ends of optical fibers to adjust brightness and ambience, then the lifelikeness is enhanced, but the device complexity increases
Solution Approach 1:
The patent merges multiple light sources and their control functions into a unified system at the input ends of the optical fibers. By combining the light sources, control elements, and optical fibers into an integrated assembly, the system manages complexity through consolidation. The multiple light sources work together as a coordinated unit to adjust brightness, ambience, and other visual properties, enhancing lifelikeness while keeping the overall structure manageable.
