Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single insulation element is used to achieve bi-directional transmission, then the number of insulation elements is reduced, but additional circuits such as reception timing circuits are required which increases device complexity
Solution Approach 1:
The patent applies periodic action by implementing distinct operation modes (first operation mode and second operation mode) that alternate in time. The first circuit operates in transmission mode during one period and reception mode during another period, while the second circuit operates in reverse. This temporal separation allows a single insulation element to handle bi-directional transmission without requiring complex additional circuits for timing coordination.
Solution Approach 2:
The patent implements dynamics by making the operational state of the circuits changeable over time. Each circuit can dynamically switch between transmission and reception states based on the operation mode, allowing the system to adapt its configuration periodically. This dynamic switching enables simplified bi-directional communication using a single insulation element.
2Quantity of substance
If a single insulation element is used to achieve bi-directional transmission, then the number of insulation elements is reduced, but additional circuits such as reception timing circuits are required which increases power consumption
Solution Approach 1:
The patent reduces power consumption by implementing periodic operation modes where each circuit alternates between active transmission/reception states and idle states. During idle periods, circuits can reduce or stop power consumption, while still maintaining bi-directional communication capability through the single insulation element.
Solution Approach 2:
The dynamic switching between operation modes allows circuits to optimize power consumption by being active only when needed for transmission or reception, rather than continuously operating. This reduces overall power consumption while maintaining the ability to communicate bi-directionally.
3Device complexity
If two insulation elements are used for bi-directional transmission, then the configuration is simple and reliable, but the number of components increases
Solution Approach 1:
The patent applies universality by making the single insulation element perform multiple functions - it serves as both the transmission insulation element and the reception insulation element by operating in different time periods. This multi-functionality eliminates the need for separate insulation elements for each direction, reducing component count while maintaining reliability.
Solution Approach 2:
The patent merges the function of two separate insulation elements into a single insulation element by combining their roles through temporal separation. The single insulation element handles both transmission and reception functions by switching operational modes, effectively combining what would traditionally require two separate components.

AI summary
In one embodiment, electronic circuitry comprises a first circuit capable of transmitting and receiving signals, a second circuit capable of transmitting and receiving signals, and an insulation element. The first circuit has a first terminal to which a first clock signal is input, increases the frequency of the first clock signal to generate a second clock signal, and transmits the second clock signal. The insulation element transmits the second clock signal obtained from the first circuit to the second circuit as a third clock signal. The second circuit receives the third clock signal from the insulation element, and transmits a first data signal in response to the third clock signal. The insulation element transmits the first data signal obtained from the second circuit as a second data signal. The first circuit receives the second data signal from the insulation element.
