Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional liquid crystal dropping apparatus is used, then the structure is simple, but the dropping precision is low and liquid crystal amount cannot be kept constant
Solution Approach 1:
The patent applies parameter changes by controlling the temperature of the liquid crystal to a predetermined value. The heating thermos device adjusts the temperature parameter of the liquid crystal to maintain constant density and viscosity, which directly improves dropping precision. The control unit regulates the heating member based on temperature detection to keep the liquid crystal at optimal temperature for consistent dropping.
Solution Approach 2:
The patent implements feedback control through the detecting member that continuously monitors the temperature of the liquid crystal and feeds this information back to the control unit. The control unit then adjusts the heating member accordingly to maintain the predetermined temperature, creating a closed-loop feedback system that ensures precise and consistent liquid crystal dropping.
2Stability of the object's composition
If temperature control is not applied, then the device complexity is low, but the liquid crystal density and flow become unstable
Solution Approach 1:
The patent changes and controls the temperature parameter of the liquid crystal to maintain stable density and flow characteristics. By heating the liquid crystal to a predetermined temperature and maintaining it there, the physical properties (density and viscosity) remain constant, ensuring stable composition throughout the dropping process.
Solution Approach 2:
The detecting member continuously monitors the liquid crystal temperature and provides feedback to the control unit, which adjusts the heating member to maintain stable temperature. This feedback mechanism ensures that the liquid crystal composition remains stable by compensating for any temperature fluctuations that would otherwise cause density and flow variations.
3Speed
If temperature control is not applied, then energy consumption is low, but the liquid crystal flow becomes inconsistent
Solution Approach 1:
The patent controls the temperature parameter of the liquid crystal to ensure consistent flow characteristics. By maintaining the liquid crystal at a predetermined temperature through the heating thermos device, the viscosity and flow properties remain stable, resulting in consistent dropping speed and flow rate throughout the process.
Solution Approach 2:
The detecting member monitors temperature and provides feedback to the control unit, which regulates the heating member to maintain optimal flow conditions. This feedback control ensures that the liquid crystal flow remains consistent by continuously adjusting the temperature to compensate for any deviations, ensuring uniform dropping performance.
