Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If electrostatic sprayers are used to deliver cleaning spray, then surface coverage efficiency is improved (up to 100 times more surface area), but electromagnetic radiation interference with electronic components worsens
Solution Approach 1:
The patent introduces electromagnetic shielding materials as an intermediary between the electrostatic generating unit and electronic components. These shielding materials act as a mediator that blocks or attenuates electromagnetic radiation while allowing the electrostatic spray function to operate effectively, thus protecting electronic components without compromising cleaning efficiency
Solution Approach 2:
The patent extracts or separates the harmful electromagnetic radiation effect from the useful electrostatic spray function. By using shielding structures and materials, the harmful electromagnetic radiation is contained or directed away from electronic components, while the beneficial electrostatic charging of spray particles continues to provide enhanced surface coverage
2Reliability
If high voltage is applied to generate electrostatic charge on spray, then cleaning effectiveness is improved, but electromagnetic radiation emission increases
Solution Approach 1:
The patent converts the harmful electromagnetic radiation byproduct into a managed parameter through shielding design. The high voltage electrostatic generating unit continues to operate at full effectiveness for charging spray particles, while the emitted electromagnetic radiation is captured and blocked by shielding structures, transforming an uncontrolled harmful emission into a controlled and contained phenomenon
