Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrostatic attracting structures are complex and costly to produce, requiring double processing of inter-electrode insulating layers and becoming difficult to modify or replace once integrated, limiting their configurational flexibility and increasing operational costs.
Innovation Solution
An electrostatic attracting structure comprising multiple sheet members with electrodes sandwiched between dielectric materials, where voltage application fixes the structure during use and allows for easy separation after use, enabling flexible configuration changes by canceling the voltage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If electrodes are sandwiched between dielectric materials and integrally bonded to form a strongly integrated structure, then structural strength and stability are improved, but the ability to modify or replace components after use deteriorates
Solution Approach 1:
The electrostatic attracting structure is divided into multiple independent sheet members, each comprising dielectric materials and electrodes. These sheet members can be stacked in different configurations and replaced independently, enabling flexible structural modification while maintaining strong integration during operation through electrostatic attraction.
2Reliability
If inter-electrode insulating layers are processed twice for top and back surfaces, then electrical insulation reliability is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The structure is segmented into multiple sheet members where each sheet member's dielectric materials serve as inter-electrode insulating layers. This segmentation eliminates the need for complex double-processing of single insulating layers, as each sheet member can be independently manufactured with standard processing procedures.
Solution Approach 2:
The dielectric materials in the sheet members serve multiple functions: they act as both the insulating layers between electrodes and as the attracting surfaces for objects. This multi-functionality eliminates the need for separate inter-electrode insulating layer processing.
3Stability of the object's composition
If sheet members are stacked and electrostatically attracted to form an integrated structure during use, then structural stability is improved, but the ability to separate and reconfigure after use deteriorates
Solution Approach 1:
The sheet members are designed to be periodically assembled and disassembled. During operation, electrostatic attraction maintains strong integration for structural stability. After use, the electrostatic attraction can be deactivated, allowing easy separation and reconfiguration of the sheet members without permanent bonding.

The structure maintains a strongly integrated form during use while allowing for easy separation and reconfiguration, reducing production complexity and costs, and enabling the structure to be adapted for various applications by changing the sheet member arrangement.
Implementation Method 1
by applying a voltage between the electrodes of facing sheet members by the at least one attraction power source, the facing sheet members are electrically attracted and fixed
Implementation Method 2
the dielectric materials of both of outermost sheet members including a sheet member corresponding to an outermost top surface layer and a sheet member corresponding to an outermost back surface layer attract the object to be attracted

AI summary
Provided are an electrostatic attracting structure, which electrically attracts an object to be attracted when used and which allows a strongly integrated structure to be maintained when used, and also allows the structure to be changed freely in configuration after the use, and a method of fabricating the same. The electrostatic attracting structure includes: a plurality of sheet members each having an electrode which is sandwiched between two dielectric materials; and at least one attraction power source, in which the plurality of sheet members are stacked, and by applying a voltage between the electrodes of facing sheet members by the at least one attraction power source, the facing sheet members are electrically attracted and fixed, when the electrostatic attracting structure is used, the dielectric material of any one of or both of outermost sheet members each corresponding to an outermost top surface layer or an outermost back surface layer attracts the object to be attracted, and after the use, the stacked plurality of sheet members are made separable from one another by canceling the application of the voltage. Further, by stacking the plurality of sheet members by fixing unit while subjecting the plurality of sheet members to positioning among one another, such electrostatic attracting structure can be obtained easily and reliably.
