Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional soldering methods are used to connect wires to PCBs, then electrical connections can be formed, but the process becomes tedious, inefficient, and results in high scrap rates
Solution Approach 1:
The connector is divided into separate male and female portions that can be independently assembled. The male connector attaches to the wire and the female connector attaches to the PCB, eliminating the need for soldering and reducing assembly complexity while improving connection efficiency
Solution Approach 2:
The connector acts as an intermediary component between the wire and PCB, providing a mechanical and electrical connection without requiring direct soldering. This intermediary device simplifies the connection process and reduces scrap rates by enabling easy assembly and disassembly
2Ease of repair
If soldering is used to form connections, then electrical connections are created, but repairs and replacements become difficult especially when components are not easily accessible
Solution Approach 1:
The connector employs a dynamic, reversible connection mechanism using spring-loaded contacts and snap-fit features. This allows the connection to be easily made and broken multiple times, enabling simple repairs and replacements without the permanent bonds created by soldering
Solution Approach 2:
The connector design extracts the wire connection from the PCB mounting process, allowing the wire to be connected to the male connector separately and then mated with the female connector on the PCB. This separation enables easy removal and replacement of either component without affecting the other
3Loss of time
If soldering is used to connect wires to PCBs, then electrical connections are formed, but the process is time-consuming and results in high scrap rates which are expensive
Solution Approach 1:
The connector components are pre-assembled and pre-tested before final installation. The male connector with wire attachments can be prepared in advance, and the female connector with PCB mounting can be separately assembled, reducing on-site connection time and enabling parallel manufacturing processes that improve overall manufacturing efficiency

AI summary
This disclosure provides a method and apparatus for a single pair Ethernet (SPE) wire-to-board connector. The SPE connector may include a female connector portion and a male connector portion. The female connector portion may include a first electrical contact having a first press-fit pin and a first female portion, a second electrical contact having a second press-fit pin and a second female portion, and a first outer shield, the first outer shield mechanically secured to the first insulative housing. The first and second electrical contacts may be positioned partially within the first insulative housing. The male connector portion includes a third electrical contact comprising a first insulation displacement contact (IDC) portion and a first male portion, a fourth electrical contact comprising a second IDC portion and a second male portion, and a second outer shield, the second outer shield mechanically secured to a second insulative housing.
