Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the speed of digital buses is increased to improve data transmission rate, then productivity is improved, but digital signals generate higher interference on wireless reception
Solution Approach 1:
The patent introduces adjustable resistors as intermediary components connected between the digital bus and wireless reception circuit. These resistors act as mediators that control the coupling strength between the digital signal source and the wireless receiver, allowing dynamic adjustment to minimize interference while maintaining data transmission functionality.
Solution Approach 2:
The patent employs dynamically adjustable resistors that can change their resistance values in real-time based on the interference conditions. This dynamic adjustment capability allows the system to adapt to varying data transmission rates and interference levels, optimizing both productivity and wireless reception quality under different operating conditions.
2Reliability
If adjustable resistors are added to dynamically reduce interference, then reliability of wireless reception is improved, but device complexity increases
Solution Approach 1:
The patent changes the electrical parameter (resistance) of components in the circuit to control interference. By adjusting the resistance values of the adjustable resistors, the system can dynamically modify the signal coupling characteristics without fundamentally changing the circuit architecture, thus improving reliability with relatively simple parameter adjustments.
3Object-affected harmful factors
If bandwidth is reduced to minimize interference, then harmful factors are reduced, but data transmission capacity decreases
Solution Approach 1:
The patent dynamically adjusts the bandwidth of the wireless reception circuit based on interference conditions. When interference is high, the bandwidth is reduced to filter out noisy signals; when interference is low, the bandwidth is expanded to maximize data transmission capacity. This dynamic adaptation resolves the contradiction between reducing harmful factors and maintaining productivity.

AI summary
A wireless signal interference reduction device includes a digital signal converter, an output device, a first adjustable resistor, and a second adjustable resistor. The wireless signal interference reduction device records an initial SNR value, records an SNR value of wireless reception in real-time at a preset interval when wired data transmission is turned on, determines whether a difference between the initial SNR value and the real-time SNR value is less than a preset value, continuously obtains the real-time SNR value at the preset interval to obtain the difference between the initial SNR value and the real-time SNR value if the difference between the initial SNR value and the real-time SNR value is less than the preset value, and reduces the wired transmission bandwidth by one step value if the difference between the initial SNR value and the real-time SNR value is not less than the preset value.
