Engineering Contradiction Analysis
1Power
If high voltage transformers or voltage multipliers are used in electrostatic therapeutic devices, then high voltage alternating electric field can be generated, but safety risks increase and device cost increases due to need for protection against electrical breakdown
Solution Approach 1:
The patent extracts and eliminates the high voltage transformer from the electrostatic therapeutic device, replacing it with a mechanical charge generation system using triboelectrically charged pulleys and a moving belt. This removes the source of electrical breakdown risks while maintaining the ability to generate high voltage alternating electric fields for therapeutic purposes
Solution Approach 2:
The patent replaces the electrical system (transformer) with a mechanical system (rotating pulleys with dielectric coating and moving belt) to generate high voltage. The mechanical motion of the belt over the charged pulleys creates the alternating electric field through triboelectric charging, substituting electrical transformation with mechanical charge generation
2Power
If high voltage transformers or voltage multipliers are used in electrostatic therapeutic devices, then high voltage alternating electric field can be generated, but device complexity and manufacturing cost increase due to protection circuits
Solution Approach 1:
The patent removes the high voltage transformer and associated protection circuits from the device architecture. The mechanical charge generation system inherently avoids electrical breakdown issues, eliminating the need for complex protection circuits and reducing overall device complexity
Solution Approach 2:
The mechanical charge generation system is inherently safe and self-regulating. The triboelectric charging mechanism naturally prevents electrical breakdown without requiring external protection circuits, making the system self-protecting and simpler to manufacture
