Radial Claw Plate Spring for Uniform Surface Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plate springs fail to apply a load (surface pressure) effectively to objects like cathode power feeding bodies in a uniform and consistent manner.
Innovation Solution
A plate spring design featuring a disc member with claws extending along the radial direction and warping in the thickness direction, accompanied by an annular portion, which ensures a uniform and dispersed application of surface pressure through a plurality of claws arranged in a specific pattern.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If a conventional plate spring design is used, then the structure is simple, but the surface pressure application is non-uniform and ineffective
Solution Approach 1:
The plate spring is divided into multiple functional segments: a disc member with multiple claws extending radially outward, each claw acting as an independent pressure application point. This segmentation allows the load to be distributed across multiple contact points rather than concentrated at a single location, achieving uniform surface pressure application while maintaining structural simplicity.
Solution Approach 2:
The claws are positioned at specific radial distances from the center of the disc member, creating localized pressure application zones. Each claw contacts the cathode power feeding body at a predetermined position, ensuring that pressure is applied uniformly across the entire surface area. This local quality approach optimizes pressure distribution without requiring complex overall restructuring.
2Reliability
If a plate spring applies load to cathode power feeding body, then the electrolysis device functions, but the load distribution is non-uniform causing performance issues
Solution Approach 1:
By dividing the pressure application into multiple claw segments arranged radially, the system ensures that each segment contributes equally to the overall load distribution. This segmentation prevents localized over-compression or under-compression, maintaining reliable and uniform contact between the plate spring and cathode power feeding body throughout the electrolysis process.
Solution Approach 2:
The radial arrangement of claws at equal distances from the center creates equipotential pressure distribution across the cathode power feeding body surface. Each claw applies pressure at its specific radial position, ensuring that the entire surface experiences uniform compression conditions, which is essential for consistent electrolysis performance and product quality.
