Coil Winding Connection Structure for Compact Secure Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coil devices for solenoid valves and pumps require significant space and lack a secure mechanical and electrical connection for the electrical winding, leading to inefficiencies and potential misalignment issues.
Innovation Solution
A coil device design featuring a coil body with a winding connection that clamps between the coil body and the electrical winding, providing a secure mechanical connection through a fastening section that acts perpendicular to the coil's longitudinal axis, allowing for efficient space utilization and secure attachment without additional process steps.

If a two-part sleeve design with connection contacts is used, then electrical connection is provided, but significant space is required in the horizontal direction
Solution Approach 1:
The patent combines the connection contacts with the coil body into a single integrated structure. The connection contacts are formed as extensions of the coil body itself, eliminating the need for separate two-part sleeve components. This merging reduces the horizontal space requirement while maintaining secure electrical and mechanical connection through the integrated design.
2Reliability
If a two-part sleeve design is used, then assembly is simplified, but the connection between individual parts is not secure
Solution Approach 1:
The connection contacts are integrated directly into the coil body structure, forming a unified single-piece component. This eliminates the need for assembling multiple separate parts, thereby ensuring secure mechanical and electrical connection without increasing structural complexity. The integrated design inherently provides stronger connection security compared to assembled two-part designs.
3Reliability
If additional process steps are added for secure connection, then connection security is improved, but manufacturing complexity increases
Solution Approach 1:
The connection contacts are formed as integral extensions of the coil body, allowing the entire structure to be manufactured in a single process step. The unified design eliminates the need for additional assembly operations or separate connection processes, thereby achieving secure mechanical and electrical connection without increasing manufacturing complexity.
