Engineering Contradiction Analysis
1Power
If contact-separation movement is used to generate electrical power through the triboelectric effect, then electrical power can be generated, but the output current is intermittent and alternating, limiting usefulness for DC components
Solution Approach 1:
The generator is divided into multiple independent power generation modules (first, second, and third modules) each with its own actuating element. These modules are spatially segmented around the rotating body at different angular positions, allowing them to generate power at different times during rotation, thereby converting intermittent output into continuous output.
Solution Approach 2:
The invention employs periodic contact-separation cycles of actuating elements with each power generation module. By arranging modules at different angular positions (e.g., 0°, 120°, 240°), the system creates overlapping periodic actions that sum to a continuous power output, eliminating the intermittent nature of single-module operation.
2Reliability
If multiple power generation modules are used to improve output continuity, then power generation becomes more continuous, but device complexity increases
Solution Approach 1:
Each power generation module is designed as a universal unit that can function independently. The modules are identical in structure but positioned at different angular locations, allowing them to perform the same function at different times. This modular universality simplifies design and manufacturing while achieving continuous output through temporal distribution.
Solution Approach 2:
The invention merges the outputs of multiple power generation modules into a single common output terminal. By combining the electrical outputs of modules that operate at different phases, the system achieves continuous power delivery while using standardized modular components, balancing complexity with performance.

AI summary
A triboelectric generator comprises a first body and a second body moveable relative to the first body. A plurality of power generation modules are disposed on the first body and one or more actuating elements are disposed on the second body, the plurality of power generation modules each being electrically connected to a common output and comprising material capable of generating electrical power through the triboelectric effect when brought into contact with another surface. The plurality of power generation modules and the one or more actuating elements are arranged on the first and second bodies such that relative movement of the first and second bodies causes the one or more actuating elements to come into contact with the plurality of power generation modules, wherein the contact between one of the one or more actuating elements and one of the power generation modules causes the material of said one of the power generation modules to be brought into contact with said other surface so that electrical power is generated. The triboelectric generator is configured such that the plurality of power generation modules supply electrical power to the common output at different times. Since the power generation modules output electrical power at different times, a more continuous supply of electrical power from the common output is achieved.
