Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If filtering units are added to the motherboard to enhance signal processing capabilities, then the functionality and value of the connector system is improved, but the complexity and area of the motherboard increases
Solution Approach 1:
The patent combines the connector and filtering units into a single integrated assembly. The filtering units are mounted on a carrier board that is directly attached to the connector housing, creating a composite connector that provides both connection and signal filtering functions in one unit. This eliminates the need for separate filtering components on the motherboard.
Solution Approach 2:
The composite connector serves multiple functions: it provides mechanical connection between devices, electrical signal transmission through pins, and signal filtering through integrated filtering units. This multi-functional design allows a single component to replace what would traditionally require multiple separate components on the motherboard.
2Adaptability or versatility
If filtering units are added to the motherboard to enhance signal processing capabilities, then the functionality and value of the connector system is improved, but the area of the motherboard increases
Solution Approach 1:
The filtering units are physically integrated with the connector housing through a carrier board, consolidating what would be separate space-consuming components into a single compact unit. This integration significantly reduces the total area required on the motherboard compared to having discrete filtering units distributed across the board.
3Adaptability or versatility
If additional filtering units are disposed on the motherboard, then signal processing capabilities are enhanced, but the manufacturing cost of electronic devices increases
Solution Approach 1:
The connector and filtering units are manufactured as an integrated assembly, allowing for streamlined production processes. The carrier board with filtering units is pre-mounted to the connector housing before final assembly, enabling modular manufacturing that can reduce overall production costs compared to installing multiple separate components on the motherboard.
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
The composite connector provides filtering functions while maintaining compatibility with standard connectors, reducing manufacturing costs and enhancing routing flexibility by integrating filtering units onto a separate carrier circuit board.
Implementation Method 1
The filtering function typically refers to the process where signals of different frequencies experience different gains or attenuations as they pass through a filtering unit, allowing for the retention of specific frequency components.

AI summary
A composite connector incudes a connector, a carrier circuit board, and a plurality of filtering units. The connector is disposed on at least one surface of the carrier circuit board, and multiple connection pins are disposed on at least one surface of the carrier circuit board. The carrier circuit board is disposed on a main circuit board or a main circuit board connector of the main circuit board. The filtering units are disposed on the carrier circuit board and connected to part or all of the connection pins to filter out noise on the connection pins. The composite connector of the invention can have a filtering function, thereby reducing the manufacturing cost of electronic devices and increasing the routing flexibility of the main circuit board.
