Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display device includes both a dimming element and an antenna for wireless communication, then both dimming and communication functions are provided, but the space occupied by these members increases and effective space for other components decreases
Solution Approach 1:
The patent applies multi-functionality by making the conductor serve dual purposes: it acts as an electrode for the dimming element during daytime and as an antenna for wireless communication during nighttime. This allows a single component to fulfill multiple functions, eliminating the need for separate dedicated components and thereby reducing the overall space required in the display device.
Solution Approach 2:
The patent merges the electrode of the dimming element with the antenna structure by using the same conductor for both purposes. The conductor is configured to function as the electrode when voltage is applied for dimming, and as the antenna when used for wireless communication, thereby combining two previously separate components into one integrated structure that reduces space occupation.
2Adaptability or versatility
If a display device includes both a dimming element and an antenna, then both functions are provided, but the function of communication through the antenna deteriorates or the function of the dimming element decreases
Solution Approach 1:
The patent employs periodic action by switching the conductor's function between dimming and communication based on time periods (daytime for dimming, nighttime for communication). This time-division approach ensures that each function operates at full performance during its designated period without interference from the other function, thereby maintaining high reliability for both dimming and communication.
Solution Approach 2:
The conductor's electrical characteristics are dynamically adjusted through switching between different voltage application modes. During daytime, voltage is applied to make the conductor function as a dimming electrode; during nighttime, the switching element changes the electrical characteristics to enable the conductor to function as an antenna for wireless communication, optimizing performance for the current operational mode.
3Adaptability or versatility
If the space occupied by dimming element and antenna increases, then both functions can be provided, but the effective space for arrangement of other components decreases
Solution Approach 1:
By designing the conductor to serve as both the dimming electrode and the antenna, the patent eliminates the need for separate dedicated components. This multi-functional design reduces the total volume required for housing both dimming and communication functions, thereby increasing the effective space available for arranging other components within the display device.
Solution Approach 2:
The merging of the electrode and antenna into a single conductor structure reduces the cumulative volume occupied by these components. Instead of requiring separate spaces for a dedicated electrode and a dedicated antenna, the integrated design allows both functions to share the same physical space, thereby freeing up volume for other components.
