Tapered Surface Treatment Jig for Uniform Accumulator Coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface treatment jigs result in uneven coating thickness on accumulators, with the coating thickness being smaller at the connection points between the jig and the exterior body.
Innovation Solution
A surface treatment jig with a support portion that tapers towards a hook portion, minimizing electric current differences and ensuring uniform coating thickness by promoting even adhesion of metallic ions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a columnar support portion is used to support the accumulator, then the accumulator can be supported and surface treatment can be performed, but the coating thickness becomes smaller at the connection portion between the jig and the exterior body
Solution Approach 1:
The support portion is designed with a tapered shape where the diameter gradually decreases from the bottom toward the top. This creates local variation in the support portion's geometry, with the lower section having a larger diameter to provide stable support and the upper section having a smaller diameter to reduce interference with coating deposition, thereby achieving uniform coating thickness across the exterior body surface
Solution Approach 2:
The support portion transitions from a uniform columnar shape to a tapered three-dimensional form. This dimensional change in the radial direction (diameter variation along the length) allows the jig to maintain structural integrity for support while minimizing its impact on coating thickness distribution at the connection portion
2Stability of the object's composition
If the support portion has a larger diameter, then it can provide better support stability, but it causes greater reduction in coating thickness at the connection portion
Solution Approach 1:
The diameter parameter of the support portion is varied along its length according to a tapered profile. The diameter is larger at the bottom for stability and gradually decreases toward the top, optimizing the balance between support stability and coating thickness. This continuous parameter change resolves the contradiction by distributing the diameter values optimally along the support portion
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The jig effectively minimizes the reduction in coating thickness, ensuring a consistent and sufficient coating thickness across the entire exterior body of the accumulator.
Implementation Method 1
paint is sprayed, and a metallic coating is thereby formed on a surface of the exterior body
Implementation Method 2
the support portion has a shape tapered near the hook portion... minimizing electric current differences and ensuring uniform coating thickness by promoting even adhesion of metallic ions
