Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing CAD routers do not automatically handle slit placement in electrical conductor routing on planar surfaces, leading to increased design time and potential compromise of design goals due to unacceptably high resistance values.
Innovation Solution
A computer-implemented method and system for automatically routing conductors and placing slits on planar surfaces, using a template to align slits parallel to the conductor's centerline and calculate resistance by dividing the conductor into sections with and without slits, ensuring compliance with resistance constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If slits are manually added to conductors after routing, then UV light can cure adhesives in seal regions, but design time increases and resistance constraints may be compromised
Solution Approach 1:
The routing template预先 defines slit placement rules, conductor width specifications, and resistance constraints before the routing process begins. The CAD router automatically applies these pre-defined parameters during routing, eliminating the need for manual slit addition and iterative resistance calculations after routing is complete.
Solution Approach 2:
The system incorporates automatic resistance calculation and validation feedback during the routing process. The CAD router calculates conductor resistance based on the routed path and pre-defined parameters, and automatically adjusts the routing to meet resistance constraints, providing real-time feedback to ensure design goals are met.
2Illumination intensity
If slits are manually added to conductors, then UV light transmission is enabled, but resistance calculations become complex and design goals may be compromised
Solution Approach 1:
The CAD router automatically performs resistance calculations and validates against constraints without requiring manual intervention. The system self-adjusts routing parameters, conductor widths, and slit placements to meet resistance goals, eliminating the need for designers to manually calculate and iterate on resistance values.
Solution Approach 2:
The routing template allows dynamic adjustment of parameters such as conductor width, slit spacing, and slit width to optimize resistance. The system automatically modifies these parameters during routing to ensure resistance constraints are met while maintaining UV light transmission through slits.
3Reliability
If conductor width is increased to reduce resistance, then resistance constraints are met, but the conductor may overlap more seal regions requiring additional slits
Solution Approach 1:
The routing template pre-defines the relationship between conductor width, slit placement, and resistance constraints. Before routing begins, all relevant parameters are specified, allowing the CAD router to automatically balance conductor width and slit placement to meet resistance goals without manual iteration.
Solution Approach 2:
The system dynamically adjusts multiple parameters including conductor width, slit width, and slit spacing to optimize the balance between resistance and UV light transmission. The CAD router automatically modifies these parameters during routing to achieve resistance constraints while minimizing the number and complexity of slits required.

Function Achieved in This Case
This approach reduces design time by automatically placing slits and adjusting conductor widths to meet resistance constraints, providing accurate resistance calculations and efficient routing while allowing UV light to cure adhesives in flat panel display manufacturing.
Implementation Method 1
adhesive is applied to the seals and cured by ultra-violet (UV) light. Thin films of conductors... may block some of the UV light needed to cure the adhesive adjoining the conductors. Narrow stripes, hereinafter also referred to as 'slits', represent conductor that is removed wherever conductor traces overlap seal regions so that the UV light may go through the slits and cure the adhesive during manufacture.
