Fluid Pressure Contact Pressing for Uniform Electrode Lamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressing apparatuses with flat pressing portions cannot apply uniform force to target objects with various shapes, leading to non-uniform lamination and increased production costs due to additional processing requirements.
Innovation Solution
A pressing apparatus with a contact portion having a pattern that changes pressure based on the target object's shape, utilizing a pressure adjustment portion with a fluid to distribute force uniformly, regardless of the object's shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a flat pressing portion is used in the pressing apparatus, then the structure is simple, but uniform pressing force cannot be applied to target objects with various shapes
Solution Approach 1:
The pressing portion is designed to be deformable rather than rigid, allowing it to dynamically adapt its shape to match the target object being pressed. This enables the pressing portion to conform to various shapes while maintaining uniform contact and force distribution, resolving the contradiction between simple structure and uniform pressing force application.
Solution Approach 2:
The pressing portion's physical parameters (shape, surface area, contact points) are changed based on the target object's characteristics. By adjusting the pressing portion's configuration to match different object shapes, uniform pressing force can be achieved across varied geometries without requiring completely different apparatus designs for each shape.
2Productivity
If a flat pressing portion is used, then the device structure is simple, but additional pressing processes are required for non-uniformly laminated portions
Solution Approach 1:
The pressing portion is pre-configured with a shape that matches the target object before the pressing operation begins. This preliminary shaping ensures that when pressing force is applied, uniform contact is achieved from the start, eliminating the need for subsequent additional pressing processes to correct non-uniform lamination, thereby improving productivity.
3Manufacturing precision
If stronger force is applied to protruding portions of the target object, then those portions are better pressed, but other portions receive weaker force resulting in non-uniform lamination
Solution Approach 1:
The deformable pressing portion distributes pressing force uniformly across the entire surface of the target object by conforming to its shape. This creates an equipotential force distribution where each point on the target object receives appropriate pressing force, eliminating the imbalance between protruding and depressed portions and achieving uniform lamination.
