Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drawing tools can only manually adjust the line width and line gap of differential signal pairs or adjust them at a specific angle, failing to simultaneously adjust these parameters effectively as the stacking of printed circuit boards changes.
Innovation Solution
A method and system that adjust the original line width and line gap of a differential signal pair by performing new parameter setting, distance difference of center calculation, reference polygon generation, and differential signal pair adjustment steps, using a processing unit and user interface to generate a new differential signal line pair while maintaining the same center distance ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional drawing tools are used to adjust line width and line gap, then manual adjustment or adjustment at specific angles is possible, but simultaneous adjustment of multiple parameters across various angles is not achievable
Solution Approach 1:
The patent applies parameter changes by systematically varying line width and line gap parameters across different angles simultaneously. The system changes multiple geometric parameters (line width, line gap, angle) in a coordinated manner to achieve comprehensive adjustment of differential signal line pairs, transforming the limited single-parameter or single-angle adjustment capability into multi-parameter simultaneous adjustment capability.
2Ease of operation
If manual adjustment method is used, then flexibility in adjustment is maintained, but time consumption increases significantly
Solution Approach 1:
The patent implements self-service by enabling the system to automatically perform adjustment operations without requiring manual intervention for each individual line pair. The system autonomously calculates and applies the necessary geometric transformations to multiple differential signal line pairs simultaneously, maintaining adjustment flexibility through programmable parameters while eliminating the time-consuming manual operation of adjusting each line individually.
Solution Approach 2:
The patent applies preliminary action by pre-calculating the adjustment parameters and transformation rules before executing the actual adjustment operation. The system prepares the adjustment scheme in advance, determining the optimal line width, line gap, and angular adjustments for all differential signal line pairs, then executes these pre-planned adjustments automatically, thereby reducing the time required during the actual adjustment phase while preserving flexibility through configurable parameters.
3Ease of operation
If adjustment is performed at specific angles only, then simplicity of operation is maintained, but adaptability to various stacking configurations is limited
Solution Approach 1:
The patent applies universality by designing a system that can handle multiple stacking configurations and angular orientations through a single unified adjustment mechanism. The system is capable of adjusting differential signal line pairs at any angle, not just specific predefined angles, making it universally applicable to various PCB stacking configurations. This multi-functional capability allows the same adjustment tool to serve diverse adjustment needs across different design scenarios.

AI summary
A method for adjusting a line width and a line gap of a differential signal pair includes performing a new parameter setting step, a distance difference of center calculating step, a reference polygon generating step and a differential signal pair adjusting step. The new parameter setting step is performed to set a new line width and a new line gap of the new differential signal line pair. The distance difference of center calculating step is performed to calculate a difference between an original center distance of the original differential signal line pair and a new center distance of the new differential signal line pair. The reference polygon generating step is performed to generate a reference polygon from an original center line of the original differential signal line pair. The differential signal pair adjusting step is performed to adjust the reference polygon to the new differential signal line pair.
