Electric Pulse Composite Separation Using Conductor Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric pulse decomposition methods for composite materials lack a method to concentrate the electric field effectively, making it difficult to destroy the insulating member and separate the conductors efficiently.
Innovation Solution
The method involves forming a protrusion on one of the conductors in the composite material, which reduces the dielectric strength between the conductors, allowing for easy dielectric breakdown and subsequent destruction of the insulating member by a shock wave caused by the electric pulse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a thin line is applied to apply voltage to concentrate the electric field, then the electric field can be concentrated at the intended position to destroy the insulating member, but it is difficult to select a site where the thin line is brought into contact with the conductor
Solution Approach 1:
The invention creates a local protrusion structure on one of the conductors that concentrates the electric field at a specific location. This protrusion serves as a predetermined contact point for the electrode, eliminating the difficulty of selecting contact sites while maintaining electric field concentration for effective insulating member destruction.
2Productivity
If multiple electrodes are brought into contact with spaced positions on the surface to decompose the composite material, then the object can be separated into insulator and conductor, but there is no discussion on where to concentrate the electric field to effectively destroy the insulating member
Solution Approach 1:
The protrusion is formed in advance on the conductor surface before the decomposition process. This preliminary structural modification creates a predetermined electric field concentration point, ensuring that when electrodes are applied, the electric field automatically concentrates at the intended location without requiring precise positioning control during operation.
3Productivity
If voltage is applied between electrodes to decompose the composite material, then the conductors can be separated, but the insulating member may not be effectively destroyed without proper electric field concentration
Solution Approach 1:
The protrusion creates a localized region of high electric field intensity at its tip, concentrating the decomposing action precisely where needed. This ensures reliable destruction of the insulating member at the critical interface between conductors, while the rest of the system maintains its separation function.

AI summary
An electric pulse decomposition method for separating a composite material by an electric pulse, the composite material being obtained by bonding or joining a plurality of conductors to each other with an insulating member, the electric pulse decomposition method including a protrusion formation step for forming a protrusion in a specific site, on a side on which the composite material is arranged, of at least one of the plurality of conductors, and a separation step for separating the plurality of conductors in the composite material 1 by respectively bringing electrodes into contact with surfaces of the plurality of conductors and applying an electric pulse between the electrodes to destroy the insulating member. This makes it possible to separate the plurality of conductors from the composite material by making a shock wave caused by a current of the dielectric breakdown functioning as an adhesive to effectively destroy the insulating member.
