Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If cable length is increased to extend transmission distance, then coverage area is improved, but signal attenuation increases and signal quality deteriorates
Solution Approach 1:
The connector performs preliminary actions by precisely controlling the insertion depth of each wire into the insulation displacement terminal through the cage structure and crimping mechanism. This ensures optimal electrical contact and minimizes signal attenuation before the signal even begins transmission, thereby maintaining signal quality over longer cable lengths.
Solution Approach 2:
The insulation displacement terminal design changes the connection parameters by creating multiple contact points with controlled insertion depth. This parameter optimization reduces signal loss and improves signal quality, enabling reliable transmission over extended distances without requiring cable upgrades.
2Speed
If higher frequencies are used to achieve higher data rates, then transmission speed is improved, but signal attenuation increases and noise increases
Solution Approach 1:
The connector establishes optimal electrical contacts through the insulation displacement mechanism before high-frequency signals are transmitted. This preliminary contact optimization minimizes impedance mismatches and signal reflections that would otherwise cause attenuation and noise at higher frequencies, enabling reliable 10GBASE-T transmission.
Solution Approach 2:
The insulation displacement terminal optimizes electrical parameters by creating controlled contact resistance and impedance matching through its specific geometry and material properties. This parameter control reduces signal attenuation and noise, enabling higher data rates without sacrificing signal quality.
3Reliability
If insulation penetration depth is increased to improve electrical contact, then contact reliability is improved, but wire insulation damage increases and wire strength decreases
Solution Approach 1:
The insulation displacement terminal is segmented into multiple contact points, each with controlled penetration depth. This segmentation allows the connector to achieve reliable electrical contact through distributed contacts rather than requiring deep penetration of a single contact point, thereby preserving wire strength while maintaining contact reliability.
Solution Approach 2:
The insulation displacement terminal optimizes the penetration depth parameter to create sufficient electrical contact without excessive insulation removal. This parameter control ensures reliable electrical connection while minimizing damage to the wire structure and maintaining wire strength.
4Reliability
If crimping force is increased to improve electrical connection, then contact reliability is improved, but wire deformation increases and manufacturing precision requirements increase
Solution Approach 1:
The cage structure performs preliminary positioning of the wire and insulation displacement terminal before crimping occurs. This preliminary alignment ensures that the crimping force is applied uniformly and precisely, achieving reliable electrical connection without excessive force or deformation, thereby reducing manufacturing precision requirements.
Solution Approach 2:
The crimping mechanism optimizes the applied force parameter through controlled deformation of the cage structure. This parameter control achieves sufficient electrical contact reliability while preventing wire deformation and reducing the precision requirements for the crimping process.
