Zigzag Edge Bending for Mesh Electrode Hanging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Thin expanded metal mesh and woven plain mesh electrode substrates with small wire diameters and nominal sizes experience bending, wrinkling, or breaking during etching, coating, and baking processes due to lack of rigidity, and conventional hanging methods deform or break the substrate, leading to poor surface quality and increased manpower for binding.
Innovation Solution
An edge bending jig and hanging method that bends the top and bottom ends of the mesh-type electrode substrate to form a zigzag configuration, using a pair of rod-type pressing members and die members to engage convex and concave parts, allowing the substrate to be hung without binding, thereby dispersing the hanging load and preventing internal wrinkling.

Engineering Contradiction Analysis
1Reliability
If conventional hanging methods are used for thin mesh-type electrode substrates, then the substrate can be hung for processing, but the substrate experiences bending, wrinkling, or breaking due to lack of rigidity
Solution Approach 1:
The edges of the mesh-type electrode substrate are bent into a zigzag configuration before the hanging process. This preliminary action creates engagement structures that will interact with the hanging jig, allowing the substrate to be suspended without direct contact with thin wire sections that could deform or break.
Solution Approach 2:
The substrate edge is divided into multiple engagement points through the zigzag bending, creating several contact zones with the hanging jig. This segmentation distributes the hanging load across multiple points rather than concentrating it on single wire sections, preventing local deformation and breaking.
2Stability of the object's composition
If the substrate is bound by the edges to disperse hanging load, then hanging stability improves, but working properties and efficiency deteriorate due to increased manpower for binding
Solution Approach 1:
The zigzag bending of substrate edges is performed in advance during substrate preparation, creating ready-to-engagement structures. This eliminates the need for manual binding operations during installation, as the bent edges automatically engage with the hanging jig to provide stable suspension.
Solution Approach 2:
The bent edge structures serve themselves by automatically engaging with the hanging jig slots during installation. The substrate's own geometric features (the zigzag bends) provide the hanging function without requiring external binding materials or manual tying operations.
3Stability of the object's composition
If the substrate is bound by edges to disperse load, then hanging load dispersal improves, but wrinkle formation increases due to thermal deformation during baking
Solution Approach 1:
The zigzag bending is performed before the baking process, creating a geometric structure that will accommodate thermal expansion. The bent edges engage with the hanging jig to provide load distribution, while the main substrate surface remains relatively flat and free from binding-induced wrinkles.
Solution Approach 2:
The load distribution function is separated from the main substrate surface by concentrating the engagement structures at the edges. The zigzag bends at the edges provide load dispersal, while the central substrate area maintains its planarity and is not subjected to binding-induced wrinkles.
4Ease of operation
If conventional hanging methods are used with thin substrates, then hanging is achieved, but holes for hanging deform or break due to very small rigidity
Solution Approach 1:
Instead of relying on pre-made holes that could deform or break, the edges are bent into zigzag configurations that create engagement structures. These bent edges engage with slots in the hanging jig, providing hanging capability without requiring holes to be punched or formed in the thin substrate.
Solution Approach 2:
Instead of making holes in the substrate to achieve hanging, the approach is inverted: the substrate edges are bent to create engagement structures that interface with the hanging jig. This reverses the conventional approach of modifying the substrate for hanging and instead uses edge geometry to achieve suspension.

AI summary
To provide an edge bending jig for the mesh-type electrode, an edge bending method for the mesh-type electrode substrate, a hanging jig for the mesh-type electrode substrate, and a hanging method for the mesh-type electrode substrate, which do not bind the electrode substrate of the mesh-type electrode locally, allow hanging load to disperse, prevent the internal surface of the electrode from wrinkling in the baking process, and install the electrode substrate on the hanging jig with good working properties. A bending jig and a bending method by bending the top end and the bottom end, and the external surface of the convex part and the concave part at the top end and the bottom end are bent so as to form a zigzag configuration alternately in relative to the front and rear faces of the flat plate part; and a hanging jig and a hanging method for the mesh-type electrode substrate in which the electrode substrate are hung by the electrode holding member without binding the electrode substrate, and the weight member is hung down on the bottom end of the electrode substrate without binding the electrode substrate.
