Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing discharge devices face challenges in reducing noise associated with high voltage discharge, particularly in terms of size reduction and effective noise cancellation, as they often require separate shields or substrates that complicate miniaturization and increase noise leakage.
Innovation Solution
The discharge device incorporates a transformer with a discharge electrode and an induction electrode, where a conductive path extending from one terminal to the discharge electrode and another conductive path connected to the induction electrode are positioned in proximity and opposed to each other, allowing for noise cancellation without the need for additional shielding, thereby reducing electromagnetic noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If separate shields are used to reduce electromagnetic noise, then noise reduction is achieved, but device size increases and complexity increases
Solution Approach 1:
The patent combines the noise reduction function with the existing conductive paths by positioning them in opposition, eliminating the need for separate shields. The first and second conductive paths serve both their electrical connection function and noise cancellation function through their opposing configuration, thereby reducing device size while maintaining noise reduction effectiveness.
Solution Approach 2:
The patent converts the potentially harmful electromagnetic noise generated by the discharge device into a beneficial effect by using the opposing conductive paths to generate counteracting electromagnetic fields. The noise itself becomes the mechanism for noise reduction through destructive interference, achieving noise cancellation without additional shielding components.
2Object-affected harmful factors
If separate shields are used to reduce electromagnetic noise, then noise reduction is achieved, but device complexity increases
Solution Approach 1:
The patent merges the noise reduction function into the existing electrical connection structure by positioning conductive paths in opposition. This integration eliminates separate shielding components and simplifies the overall device architecture, reducing complexity while maintaining effective noise cancellation.
Solution Approach 2:
The conductive paths serve dual functions: providing electrical connection and generating electromagnetic fields for noise cancellation. The device uses its own existing components (the conductive paths) to counteract the noise it generates, eliminating the need for separate noise reduction components and simplifying the device structure.
3Object-affected harmful factors
If substrates are greatly separated to reduce radiation noise and induction noise, then noise reduction is achieved, but device size increases
Solution Approach 1:
Instead of separating substrates in space (which increases device size), the patent positions conductive paths in opposition to each other, creating a three-dimensional configuration that enables noise cancellation within a compact footprint. This spatial arrangement in multiple dimensions allows noise reduction without increasing overall device volume.
Solution Approach 2:
The patent combines the noise reduction function with the electrical connection structure by using opposing conductive paths, eliminating the need for substrate separation. This integration achieves noise reduction while maintaining a compact device size, avoiding the trade-off between noise reduction and device miniaturization.
