Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional optical devices are used, then the device structure is simple and manufacturing is easy, but the optical properties cannot be dynamically adjusted
Solution Approach 1:
The patent applies the dynamics principle by incorporating organic materials that can dynamically change their optical properties in response to external stimuli such as voltage, current, or chemical compounds. These materials allow the optical device to transition between different states (e.g., transparent to opaque, or changing refractive index), enabling real-time adjustment of optical characteristics without requiring complex mechanical moving parts.
Solution Approach 2:
The patent utilizes parameter changes by altering the physical or chemical state of organic materials to modify optical properties. External stimuli change parameters such as the refractive index, absorption characteristics, or transparency of the organic material, thereby tuning the optical response of the device. This allows for continuous adjustment of optical behavior through controlled parameter variation.
2Adaptability or versatility
If conventional optical devices are used, then the manufacturing cost is lower, but the functionality and versatility are limited
Solution Approach 1:
The patent employs parameter changes by using organic materials whose optical properties can be tuned through external stimuli. This allows a single device structure to perform multiple functions by changing the state of the organic material, thereby increasing functional versatility without requiring multiple separate devices or complex manufacturing processes for each function.
Solution Approach 2:
The patent applies universality by designing an optical device that can perform multiple functions through the use of tunable organic materials. The same device structure can serve as a filter, shutter, or tunable element by adjusting the optical properties of the organic material in response to different stimuli, eliminating the need for separate components for each function.
3Speed
If static optical materials are used, then the device is simple and reliable, but it cannot respond to external stimuli in real-time
Solution Approach 1:
The patent applies dynamics by using organic materials that can rapidly respond to external stimuli such as voltage changes, current application, or chemical compound exposure. These materials enable the optical device to dynamically adjust its properties in real-time while maintaining operational reliability through controlled and reversible transitions between different optical states.
