Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing starter contactors for motor vehicles face issues with electrical connections due to vibrations, leading to wear and potential severing of winding portions, causing unreliable power supply and operation.
Innovation Solution
Incorporating guide and reduction means to securely insert and maintain the conductive segment portions within the guide means, preventing contact with the magnetic body and ensuring immobilization, thus preventing wear and ensuring a stable electrical connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the guide lugs are laterally open to allow insertion of winding portions, then the ease of assembly is improved, but the reliability deteriorates due to vibrations causing winding portions to move or come out
Solution Approach 1:
The guide means is inserted into the orifice of the magnetic body, creating a nested structure where the guide means is contained within the magnetic body's orifice. This nesting provides both insertion capability and retention function, resolving the contradiction between ease of assembly and reliability.
Solution Approach 2:
The guide means acts as an intermediary component between the winding support and the magnetic body. It provides a controlled passage for the winding portions while preventing their unwanted movement, thus mediating between the need for insertion and the need for secure retention.
2Ease of operation
If the guide lugs are open to allow winding portions to be inserted, then the ease of operation is improved, but the object-generated harmful factors worsen due to contact with magnetic body causing wear and potential severing
Solution Approach 1:
The guide means is nested within the orifice of the magnetic body, creating a protective structure that allows insertion while preventing harmful contact between the winding portions and the magnetic body, thus eliminating wear and potential severing.
Solution Approach 2:
The guide means converts the potentially harmful open structure into a beneficial protected passage. By providing a defined insertion path within the magnetic body's orifice, it transforms the risk of uncontrolled movement into a controlled, protected insertion mechanism that prevents wear and damage.

AI summary
The contactor (29) has a magnetic body (35) arranged between a winding support (38) and a hood (30). The body has orifices permitting passage of a portion of conducting segments of an electric winding (36) through the body for connecting the segment with an electric connection module (31) of the hood. Guiding units e.g. guiding brackets, include insertion spaces through which the portion of the segment is inserted in the guiding units. Reduction units e.g. snug, reduce diameter of the spaces to a value lower than diameter of the portion of the segment. An independent claim is also included for a method for assembling a contactor of a starting device.
