Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed driving voltage is applied to the anti-peep element, then the device structure is simple, but the privacy protection effect is lost in low temperature environments
Solution Approach 1:
The patent implements dynamic voltage adjustment by making the driving voltage adaptable to temperature changes. The driving circuit modifies the voltage applied to the anti-peep element based on environmental conditions, transitioning from a static to a dynamic system that maintains optimal performance across varying temperatures.
Solution Approach 2:
The patent changes the electrical parameter (driving voltage) in response to temperature variations. By adjusting the voltage magnitude according to temperature conditions, the system maintains effective privacy protection without requiring structural modifications to the anti-peep element itself.
2Reliability
If the driving voltage is increased to maintain anti-peep mode in low temperatures, then the privacy protection is maintained, but the energy consumption increases
Solution Approach 1:
The system dynamically adjusts voltage based on real-time temperature conditions rather than maintaining a constantly high voltage. This dynamic approach ensures energy is only increased when necessary for maintaining privacy protection, optimizing the balance between effectiveness and energy consumption.
Solution Approach 2:
The temperature sensor provides feedback about environmental conditions to the driving circuit, which then adjusts the driving voltage accordingly. This closed-loop feedback mechanism ensures voltage is optimized for current conditions, preventing unnecessary energy consumption when high voltage is not required for effective privacy protection.
3Reliability
If the driving voltage is increased to maintain anti-peep mode in low temperatures, then the privacy protection is maintained, but the response time increases
Solution Approach 1:
The patent optimizes the voltage parameter specifically for low-temperature conditions where liquid crystal response is naturally slower. By applying a higher voltage in these conditions, the system compensates for the reduced molecular mobility and maintains acceptable response times despite the temperature challenge.

AI summary
An anti-peep module including an anti-peep element, a driving circuit, a voltage adjustment circuit and a temperature sensor is provided. The anti-peep element includes a liquid crystal layer, a first anti-peep electrode layer and a second anti-peep electrode layer. The liquid crystal layer is located between the first and second anti-peep electrode layers. The temperature sensor is adapted to sense an ambient temperature. The voltage adjustment circuit is coupled to the temperature sensor. The driving circuit is coupled to the voltage adjustment circuit and the anti-peep element. When the ambient temperature is a first ambient temperature and the anti-peep element operates in an anti-peep mode, the driving circuit outputs a first driving voltage to the anti-peep element; when the ambient temperature is a second ambient temperature and the anti-peep element operates in the anti-peep mode, the driving circuit outputs a second driving voltage to the anti-peep element.
