Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soldering connections are used to join connectors to printed circuit boards, then reliable electrical connection is achieved, but manufacturing complexity increases and manufacturing errors occur more frequently
Solution Approach 1:
The patent replaces the traditional soldering mechanical system with a pressure-mounted electrical connection system. The connector features a housing with a pressing portion that applies mechanical pressure to clamp the electrical connection portion onto the circuit board contact portions, eliminating the need for thermal soldering processes while maintaining reliable electrical connections.
Solution Approach 2:
The patent extracts the soldering process entirely from the connection system. By designing a dedicated pressing portion within the housing that independently applies clamping force to the electrical connection portion, the system separates the mechanical attachment function from the electrical connection function, allowing pressure-mounted connections to replace soldering without requiring soldering equipment or processes.
2Quantity of substance
If cable density is increased to route more signals, then signal routing capacity improves, but signal integrity deteriorates due to interference
Solution Approach 1:
The patent applies local quality by providing individual shielding for each electrical connection portion or group of connection portions. The housing includes shielding structures positioned locally around specific signal paths, allowing high-density cable arrangement while maintaining signal integrity through localized electromagnetic interference protection for each signal channel.
Solution Approach 2:
The patent introduces shielding structures as intermediary elements between adjacent electrical connection portions. These shielding portions act as mediators that block electromagnetic interference between closely spaced signals, enabling high-density routing while preserving signal quality by isolating each signal path from its neighbors.
3Volume of moving object
If connector size is reduced to occupy minimal space, then space utilization improves, but manufacturing precision requirements increase
Solution Approach 1:
The patent segments the connector into distinct functional portions: a housing, an electrical connection portion, and a pressing portion. This segmentation allows each component to be manufactured and assembled separately with standardized tolerances, reducing the cumulative precision requirements that would arise from manufacturing a single integrated miniaturized component while still achieving compact overall dimensions.

AI summary
A connector configured to connect densely disposed cables to a board. The connector may include two or more rows of terminals held by a housing such that the two or more rows of terminals are at a same height with respect to a board that the connector would be mounted to. Such a configuration enables the connector to fit into a space limited by, for example, another component mounted to the board. The terminals may include first contact portions configured to be mounted onto a surface of the board when pressure is applied to the terminals so as to avoid the use of materials that may cause undesired shorting such as soldering materials. The terminals may include second contact portions configured to receive the cables. The second contact portions of ground terminals of a same row may be connected by a strip configured to contact shields of cables attached to the row.
