Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the driving frequency of the processor is increased to provide diverse functions and high-resolution images, then the productivity and functionality of the electronic device are improved, but the electro-magnetic interference (EMI) noise generated in the driving circuit increases, affecting device operations
Solution Approach 1:
The patent applies the 'Blessing in disguise' principle by converting the harmful EMI noise into a beneficial effect. The processor intentionally generates a compensation signal that creates a magnetic field opposite to the EMI noise, effectively using the same electromagnetic mechanism to counteract the interference. This transforms the harmful electromagnetic effect into a useful noise-cancellation mechanism.
Solution Approach 2:
The patent implements 'Preliminary anti-action' by generating a compensation signal in advance that creates a magnetic field opposing the expected EMI noise. The processor proactively produces this counteracting magnetic field before the EMI noise can interfere with device operations, thereby preventing the harmful effects rather than merely responding to them.
2Manufacturing precision
If the resolution and driving frequency are increased to improve image quality, then the visibility and performance are enhanced, but the EMI noise magnitude increases, affecting device operations
Solution Approach 1:
The patent converts the harmful EMI noise generated by high-resolution image processing into a beneficial effect. By using the same electromagnetic mechanism that produces EMI noise, the system generates a compensation magnetic field that counteracts the interference, allowing high-resolution processing without the detrimental effects of EMI noise.
Solution Approach 2:
The patent implements a feedback mechanism where the processor monitors the EMI noise generated during high-resolution image processing and dynamically adjusts the compensation signal accordingly. The compensation signal is generated based on the actual EMI conditions, creating a closed-loop system that continuously counteracts the interference to maintain stable device operations.
