Engineering Contradiction Analysis
1Reliability
If connection devices and reinforcements are used to establish permanent bonds between transmission line components, then mechanical stability and electrical contact reliability are improved, but signal quality and transmission performance deteriorate due to impedance mismatch
Solution Approach 1:
An impedance control structure is introduced as an intermediary element between the electrical conductors and the bonding region. This structure serves as a mediator that gradually transitions the impedance from the conductor's original impedance to the bonded impedance, preventing abrupt impedance mismatch and reducing signal reflection while maintaining reliable electrical contact.
Solution Approach 2:
The impedance control structure utilizes a material with a specific relative permittivity that differs from both the surrounding insulation material and the bonding reinforcement. By changing the dielectric parameter (permittivity) in the bonding region, the impedance is continuously adjusted along the transmission path, eliminating abrupt impedance discontinuities and improving signal quality.
2Stability of the object's composition
If connection devices and reinforcements are used to establish permanent bonds between transmission line components, then mechanical stability is improved, but transmission performance deteriorates due to impedance mismatch
Solution Approach 1:
The impedance control structure acts as a transition zone that mediates between the mechanical reinforcement needed for stable bonding and the electrical performance required for high-frequency signal transmission. It allows the bonding reinforcement to provide mechanical stability while the impedance control structure maintains transmission performance by managing impedance transitions.
Solution Approach 2:
The impedance control structure is localized specifically at the bonding region where impedance mismatch occurs. The material properties (relative permittivity) are changed only in this specific local area, allowing the rest of the transmission line to maintain its original characteristics while addressing the impedance issue at the critical bonding point.
3Object-affected harmful factors
If impedance control structure with high permittivity insulation material is introduced to adjust impedance, then signal integrity is improved, but device complexity increases
Solution Approach 1:
The impedance control structure is merged with the bonding reinforcement into a single integrated component. Instead of being separate elements, the impedance control function and mechanical bonding function are combined in one structure, reducing the number of discrete parts and simplifying the overall device while maintaining signal integrity.
Solution Approach 2:
The impedance control structure serves multiple functions simultaneously: it provides impedance transition to reduce signal reflection, offers mechanical support for the bonded conductors, and maintains the structural integrity of the connection device. This multi-functionality reduces the need for additional components and simplifies the overall design.
