Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 3D glasses are designed with fixed polarization direction lenses, then the glasses can properly view images from monitors with matching polarization directions, but the glasses cannot be used with monitors having different polarization directions
Solution Approach 1:
The patent applies the dynamics principle by making the polarization direction of the lenses adjustable rather than fixed. The LC (liquid crystal) layers can change their polarization orientation dynamically in response to applied voltages, allowing the same glasses to adapt to different monitor polarization directions. This resolves the contradiction by enabling one pair of glasses to work with multiple monitor types without requiring multiple fixed-design glass pairs.
Solution Approach 2:
The patent utilizes parameter changes by modifying the polarization angle parameter of the LC layers through voltage control. By changing the voltage applied to the LC layers, the polarization direction parameter can be adjusted to match different monitor types (TN, IPS, VA, etc.). This allows a single glasses design to accommodate multiple polarization directions, eliminating the need for multiple specialized glass designs.
2Reliability
If manufacturers redesign 3D glasses for each monitor type, then the glasses can be optimized for specific polarization directions, but the production cost increases
Solution Approach 1:
The patent applies universality by designing a single pair of 3D glasses that can function with multiple types of monitors having different polarization directions. The LC layers' ability to adjust their polarization orientation enables the glasses to be universally compatible with TN, IPS, VA and other monitor types, eliminating the need for manufacturers to produce multiple specialized glass designs and thereby reducing production costs.
Solution Approach 2:
The dynamic adjustability of the LC layer polarization direction allows one glasses design to serve multiple functions across different monitor types. This dynamic capability replaces the need for multiple static designs, simplifying the manufacturing process and reducing costs while maintaining optimal performance across various monitor technologies.
3Adaptability or versatility
If users purchase multiple pairs of 3D glasses for different monitor types, then they can view stereo images on any monitor, but unnecessary waste occurs
Solution Approach 1:
The patent enables a single pair of 3D glasses to be universally used with multiple monitor types through the voltage-controlled polarization adjustment of LC layers. Users no longer need to purchase separate glasses for different monitor types, eliminating waste from unused specialized glasses while maintaining the ability to view stereo images on any monitor.
Solution Approach 2:
The dynamic polarization adjustment capability allows one pair of glasses to replace multiple pairs, each optimized for specific monitor types. By adjusting the LC layer orientation via voltage control, users can adapt the same glasses to different monitors, preventing the waste associated with owning and storing multiple unused glass pairs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Reduces production costs by eliminating the need for multiple designs and allows users to view stereo images on various monitors with different polarization directions using a single pair of glasses.
Implementation Method 1
Each lens of the 3D glasses 100 comprises a front polarized lens 102, a liquid crystal (LC) layer 104 and a back polarized lens 106. In accordance with the operation of the 3D glasses 100, the voltage VLC on the LC layer 104 determines whether light is allowed to transmit through the lens.
Implementation Method 2
the voltage VLC on the LC layer 104 determines whether light is allowed to transmit through the lens. For example, when the voltage VLC on the LC layer 104 is 0V, light transmitted through the LC layer 104 has its polarization direction changed to 45 degrees
