Battery Cap Sealing Ring Coating for Uniform Glue Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing process of applying multiple types of glue to a battery cap's sealing ring results in uneven surfaces and poor sealing due to the use of a roller device, leading to inadequate sealing performance.
Innovation Solution
A two-stage coating process is employed, where a first colloid is applied to the entire surface of the sealing member's body, followed by a second colloid being applied only to specific areas, avoiding interference with the roller device and ensuring even application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a roller device is used to apply the second type of glue to the entire surface of the sealing ring, then the coating process can be completed, but the previously applied first type of glue is subjected to collision and friction causing uneven surface and poor appearance
Solution Approach 1:
The first type of glue is applied to the local area of the sealing ring before applying the second type of glue to the entire surface. This preliminary action ensures that the first glue is already in place and protected when the roller device applies the second glue, preventing the collision and friction issues that would occur if the roller tried to apply both glues simultaneously.
Solution Approach 2:
The coating process is divided into two separate stages: first applying the first type of glue to specific local areas, then applying the second type of glue to the entire surface. This segmentation allows each glue type to be applied with appropriate methods without interfering with the other, maintaining surface uniformity while completing the coating process.
2Reliability
If multiple layers of different types of glue are laminated and coated on the sealing ring, then sealing ability is improved, but the roller device causes collision and friction leading to poor sealing
Solution Approach 1:
The first type of glue is applied to the local area of the sealing ring before applying the second type of glue to the entire surface. This preliminary action ensures that the first glue is already in place and protected when the roller device applies the second glue, preventing the collision and friction issues that would occur if the roller tried to apply both glues simultaneously.

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
This approach enhances the sealing performance by preventing uneven surfaces and improving the sealing between the sealing member and battery components, such as the rupture disk and battery case.
Implementation Method 1
a first colloid is applied on a surface of the body
Implementation Method 2
a second colloid is applied at positions where the first colloid is located on any one or a combination of two of the first surface and the second surface
