Accumulator Lid Socket Segmented Sliding Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing of accumulators, particularly starter batteries, is hindered by increased friction and alignment issues when inserting pole shafts into connection sockets, which are not exactly aligned or are slightly inclined, leading to difficulties in producing a secure and gas-tight connection.
Innovation Solution
The use of multiple strip-shaped sliding elements spaced apart over the inner circumference of the connection socket reduces friction and allows for flexible adjustment, enabling easier alignment and insertion of pole shafts, and can be integrated into the cover part's design for improved production processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a single sliding element completely surrounds the pole shaft is used, then friction between the connection socket and pole shaft is reduced, but the contact surface is large and manufacturing complexity increases
Solution Approach 1:
The single sliding element is divided into multiple strip-shaped sliding elements spaced apart from each other. This segmentation reduces the total contact surface area between the sliding elements and the pole shaft, thereby reducing friction while also simplifying manufacturing compared to a single complex surrounding element.
2Manufacturing precision
If the pole shaft is slightly inclined and not exactly aligned with the connection socket, then alignment difficulties occur, but using a single sliding element does not provide sufficient adjustment flexibility
Solution Approach 1:
Multiple strip-shaped sliding elements spaced apart provide gaps that allow the pole shaft to be adjusted during insertion. This segmentation enables the pole shaft to self-align even when slightly inclined, improving both alignment precision and insertion ease.
Solution Approach 2:
The spaced-apart sliding elements allow dynamic adjustment during the insertion process. The gaps between strips enable the pole shaft to move and align itself as it enters the connection socket, accommodating minor misalignments and inclinations.
3Force
If two parts made of lead (pole shaft and connection socket) come into contact, then high friction occurs, but sliding elements reduce this friction significantly
Solution Approach 1:
The sliding elements act as intermediary components between the lead pole shaft and lead connection socket. These sliding elements provide a low-friction interface that prevents direct high-friction contact between the two lead parts, significantly reducing friction during insertion while maintaining manufacturing simplicity.
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 design minimizes disruptive friction during the assembly of the accumulator, prevents unwanted pressing of pole shafts, and facilitates a secure, low-friction insertion and welding of the connection socket to the pole shaft, enhancing the manufacturing efficiency and reliability of the accumulator production.
Implementation Method 1
The sliding elements can significantly reduce the relatively high friction that occurs when two parts made of lead come into contact.
