Male Connector for Sensor Guide Wire
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing of conventional male connectors for sensor guide wires is time-consuming and expensive due to the complex process of creating and assembling thin flexible sheets with electrical leads.
Innovation Solution
A male connector design featuring spaced apart conductive members and insulating areas formed on a planar sheet of thin flexible material, where conductive members are on one surface and insulating areas are on the other, allowing for easier formation into a helically wound or longitudinally folded structure with conductive members inside and insulating areas outside, facilitating connection with signal transmitting cables.

Engineering Contradiction Analysis
1Reliability
If conventional male connectors are manufactured using thin flexible sheets with electrical leads, then the connector provides proper electrical connection, but the manufacturing process becomes time-consuming and expensive
Solution Approach 1:
The connector is divided into modular components: a body portion and a contact assembly that can be manufactured separately and then assembled. The contact assembly includes contacts, insulating material, and a contact plate that are pre-assembled as a unit before attachment to the body, simplifying the overall manufacturing process while maintaining reliable electrical connections
Solution Approach 2:
The contact assembly is pre-assembled with contacts, insulating material, and contact plate before final assembly to the connector body. This preliminary assembly of critical components ensures proper electrical connection is established early in the manufacturing process, reducing complexity in later steps
2Reliability
If conventional male connectors are manufactured with complex assembly processes, then proper electrical connections are achieved, but production time increases and costs rise
Solution Approach 1:
The connector is divided into modular components: a body portion and a contact assembly that can be manufactured separately and then assembled. The contact assembly includes contacts, insulating material, and a contact plate that are pre-assembled as a unit before attachment to the body, simplifying the overall manufacturing process while maintaining reliable electrical connections
Solution Approach 2:
Multiple components (contacts, insulating material, and contact plate) are merged into a single pre-assembled contact assembly unit. This consolidation allows the components to be manufactured and prepared together, then installed as one unit, significantly improving production efficiency while ensuring proper electrical connections
