Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wetting current circuit is preset in each broadband link card, then wire splices are protected from oxidation, but device complexity and cost increase
Solution Approach 1:
The patent makes the broadband link card capable of both providing wetting current to protect wire splices and maintaining broadband communication functionality. The link card integrates a wetting current output terminal that can switch between communication mode and wetting current provision mode, allowing a single device to serve multiple functions without requiring separate dedicated wetting current circuits.
2Reliability
If wetting current function is integrated in SHDSL link cards, then wire splices are protected, but system cost increases
Solution Approach 1:
The patent enables existing broadband link cards to provide wetting current functionality without requiring separate dedicated wetting current circuits. The link card integrates both communication and wetting current provision capabilities, reducing the need for additional components and simplifying the manufacturing process while maintaining connection reliability.
3Reliability
If wetting current is provided continuously on all lines, then wire splices are protected from oxidation, but power consumption increases
Solution Approach 1:
The patent implements intermittent wetting current provision rather than continuous current on all lines. The system detects which lines require wetting current and provides current only to those specific lines at specific times, reducing overall power consumption while maintaining protection effectiveness for oxidized connections.
4Reliability
If broadband link cards are replaced to support wetting current, then wire splices are protected, but device replacement cost and complexity increase
Solution Approach 1:
The patent modifies existing broadband link cards to provide wetting current functionality without requiring complete device replacement. The link card is designed to operate in multiple modes (communication mode and wetting current provision mode), allowing operators to upgrade to protected connections while reusing existing infrastructure wherever possible.
