Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data transmission rate is increased above 1 Gbit/s, then data transmission capability is improved, but signal quality deteriorates making practical transmission impossible
Solution Approach 1:
The insulating body is divided into a front part and a rear part, with each part containing specific conductors that form detachable electrical connections. This segmentation allows for optimized signal paths and reduced interference, enabling high-speed data transmission while maintaining signal quality through modular conductor arrangements and targeted shielding strategies.
2Ease of repair
If the front part of the insulating body is made replaceable, then ease of maintenance is improved, but device complexity increases due to detachable connections
Solution Approach 1:
The insulating body is segmented into front and rear parts with detachable electrical connections between them. This allows the front part to be easily replaced for maintenance while keeping the rear part with cable connections intact, improving ease of repair despite the added complexity of detachable connections.
Solution Approach 2:
The front part of the insulating body with its conductors is designed as a replaceable component that can be easily exchanged when worn or damaged, rather than replacing the entire connector assembly. This reduces maintenance costs and complexity despite the detachable connection design.
3Reliability
If shield planes are added to reduce crosstalk, then signal quality is improved, but device complexity increases
Solution Approach 1:
Shield planes are strategically placed between conductor groups in the front and rear parts of the insulating body to reduce crosstalk and improve signal quality. The segmented structure allows for optimized shielding arrangements that minimize interference without requiring excessive shielding material or complex configurations.
