Solution Overview
Problem
Conventional electrostatic induction power generators face significant challenges in accurately maintaining the distance between substrates, leading to large dimensional errors that affect power generation performance, requiring multiple adjustment members and increasing time and cost.
Innovation Solution
The introduction of a regulating member, such as a rotatable spherical or roller member, within a housing with guide grooves or positioning holes, allows for precise control of the distance between substrates, reducing errors to only those of the member and housing, while maintaining a constant distance between substrates, thereby improving accuracy and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If adjustment members are used to adjust the distance between substrates, then the distance can be adjusted, but the dimensional error affecting power generation performance becomes large due to error propagation from multiple components
Solution Approach 1:
The invention extracts the distance regulation function from multiple adjustment members and support structures, and concentrates it into a single regulating member. This regulating member is configured to contact only one substrate and regulate the distance to the other substrate, thereby eliminating error propagation from multiple components and achieving high precision distance control.
Solution Approach 2:
The invention changes the parameter of distance regulation from a multi-component adjustable system to a single-component constant distance system. The regulating member is designed with a specific shape (such as a spherical member or roller) that inherently maintains a constant distance between substrates, eliminating the need for complex adjustment mechanisms and reducing dimensional errors.
2Measurement precision
If multiple adjustment members are used to control substrate distance, then distance adjustment is possible, but device complexity and manufacturing cost increase
Solution Approach 1:
The invention extracts the distance regulation function from multiple adjustment members and support structures, and concentrates it into a single regulating member. This regulating member is configured to contact only one substrate and regulate the distance to the other substrate, thereby eliminating error propagation from multiple components and achieving high precision distance control.
Solution Approach 2:
The regulating member integrates multiple functions into a single component: it serves as both a support element and a distance regulation element. By making the regulating member contact only one substrate and regulate the distance to the other substrate, it performs both support and precision positioning functions simultaneously, reducing the number of components required.
3Measurement precision
If multiple adjustment members are used to adjust substrate distance, then distance can be controlled, but adjustment time and manufacturing cost increase
Solution Approach 1:
The invention extracts the distance regulation function from multiple adjustment members and support structures, and concentrates it into a single regulating member. This regulating member is configured to contact only one substrate and regulate the distance to the other substrate, thereby eliminating error propagation from multiple components and achieving high precision distance control.
Solution Approach 2:
The regulating member is pre-configured with a specific shape and position to automatically maintain the desired distance between substrates. This preliminary configuration eliminates the need for complex adjustment operations during assembly, reducing adjustment time and simplifying the manufacturing process while maintaining high precision.

AI summary
There is provided an electrostatic induction power generator which can easily improve the accuracy of a distance between surfaces of a pair of substrates facing each other. The electrostatic induction power generator includes a spherical member 151 for making a distance between surfaces of a first substrate 120 and a second substrate 130 facing each other constant. A housing 110 is provided with a first reference surface 111 to which a surface of the second substrate 130 facing the first substrate 120 is fixed and which is a positioning reference for the second substrate 130 with respect to the surface facing the first substrate 120 in a vertical direction, and a second reference surface 112a with which the spherical member 151 is slidably in contact and which is a positioning reference for the spherical member 151 with respect to the surface facing the first substrate 120 in the vertical direction. The spherical member 151 is slidably in contact with a surface of the first substrate 120 facing the second substrate 130.
