Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display module is used to enable expansion and contraction, then adaptability and user convenience are improved, but reliability deteriorates due to defects generated during expansion and contraction operations
Solution Approach 1:
The patent applies the Dynamics principle by implementing a motorized driving system with screws that enables precise and controlled dynamic adjustment of the display module between expanded and contracted states. The motor-driven mechanism ensures smooth transitions and stable positioning at each state, reducing operational defects and improving reliability while maintaining adaptability.
Solution Approach 2:
The patent implements the Feedback principle through a driver system that controls the motor to accurately manage the expansion and contraction of the display module. The driver receives control signals and provides feedback control to ensure precise positioning and stable operation, thereby reducing defects and improving the reliability of the display module during state transitions.
2Reliability
If a motorized driver system with screws is implemented to control expansion and contraction, then reliability is improved by reducing defects, but device complexity increases
Solution Approach 1:
The patent applies the Universality principle by designing a driver system where the motor and screw mechanism serve multiple functions: driving the expansion and contraction of the display module, positioning the display at precise locations, and maintaining stable operation during transitions. This multi-functionality reduces the need for additional separate components, thereby improving reliability without proportionally increasing complexity.
3Ease of operation
If the display module is made flexible and foldable to improve portability, then ease of operation is improved, but manufacturing precision deteriorates due to defects during expansion and contraction
Solution Approach 1:
The patent applies the Dynamics principle by using a motorized screw mechanism to dynamically control the expansion and contraction of the flexible display module. This controlled dynamic adjustment ensures that the display transitions smoothly between states with precise positioning, maintaining manufacturing precision while preserving the ease of operation and portability benefits of flexible displays.
