Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electrical connectors with conductive terminals are used to electrically connect chip modules to circuit boards, then electrical connection is established, but false soldering or poor soldering occurs frequently due to the small size and large number of conductive terminals
Solution Approach 1:
The patent replaces the traditional soldering-based mechanical electrical connection system with an elastic compression-based electrical connection system. The elastic body compresses the first conductors against the second conductors to establish electrical connection, eliminating the need for soldering processes and thereby avoiding false or poor soldering issues associated with conventional connectors.
Solution Approach 2:
The patent changes the connection mechanism from rigid soldered joints to elastic compression contacts. By utilizing the elastic properties of the body and the compressive force applied during assembly, the connection parameters shift from permanent soldered bonds to reversible elastic contacts, improving reliability while simplifying manufacturing.
2Ease of manufacture
If conductive terminals are soldered to the circuit board, then electrical connection is established, but the process is complex and error-prone
Solution Approach 1:
The patent substitutes the complex soldering process with a simple elastic compression mechanism. The connector is assembled by placing the elastic body and conductors into the housing, where they are automatically compressed against the circuit board conductors during module installation, eliminating soldering entirely and greatly simplifying manufacturing while maintaining reliable electrical connection.
Solution Approach 2:
The elastic body automatically performs the electrical connection function through its inherent elastic properties. When the chip module is installed and compresses the elastic body, the conductors are automatically pressed against the circuit board conductors without requiring external soldering operations, making the system self-connecting and simplifying assembly.
3Adaptability or versatility
If the number of conductive terminals is increased to accommodate more connections, then connectivity is improved, but the risk of false soldering increases
Solution Approach 1:
The patent replaces the soldering-based multi-conductor connection system with an elastic compression-based system. The first conductors embedded in the elastic body can independently compress against multiple second conductors on the circuit board, providing high connectivity capacity without the reliability issues of soldering that plague conventional multi-terminal connectors.

AI summary
An electronic device electrically connected to an external electronic component is provided. The electronic device comprises first conductors for contacting the external electronic component and a base. The base has holes with second conductors disposed on inner walls thereof and an elastic body having terminal receiving holes for receiving the first conductors. The first and second conductors and the elastic body are disposed at appropriate positions. When the external electronic device presses and contacts the first conductors, the elastic body is forced to deform, and the first conductors are made to move to contact the second conductors. As the elastic body has good elasticity, the first conductors after being compressed can contact the second conductors of the base, and thus soldering is not required, which facilitates the electrical connection to a chip module.
