Solution Overview
Problem
The existing design review process for printed circuit boards is cumbersome and prone to errors, especially when multiple designers are geographically remote, due to the reliance on manual interpretation and communication of text-based feedback in layout design software tools.
Innovation Solution
A graphical user interface (GUI) is implemented for printed circuit board design tools that allows real-time entry, storage, and display of comments directly on the layout, enabling multiple users to view and implement changes efficiently, with tools for manipulating the layout and storing comments as attribute data associated with components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If text-based spreadsheet feedback or paintbrush type markups are used for design review, then the review process can be performed, but the process becomes cumbersome and prone to errors requiring manual interpretation
Solution Approach 1:
The patent replaces manual mechanical processes (reading text-based feedback, interpreting paintbrush markups, manual communication between designers) with an automated computer-based system that displays feedback comments directly on the graphical layout. The system automatically associates comments with specific layout elements and enables direct editing, eliminating the need for manual interpretation and reducing errors.
Solution Approach 2:
The patent introduces a computer-based feedback display system as an intermediary between the layout data and the designers. This intermediary automatically processes, displays, and manages feedback comments, serving as a mediator that eliminates direct manual communication and reduces the cumbersome nature of the review process while improving accuracy.
2Reliability
If manual interpretation and communication of feedback comments is used, then designers can review layouts, but the process is time-consuming and efficiency is reduced
Solution Approach 1:
The patent replaces manual interpretation and communication processes with an automated computer-based system that displays feedback comments directly on the graphical layout, automatically associates them with specific elements, and enables direct editing. This substitution eliminates time-consuming manual steps and significantly improves design review efficiency.
Solution Approach 2:
The system enables designers to directly edit layout elements by interacting with displayed feedback comments without requiring manual communication or interpretation steps. The automated display and direct editing capabilities allow designers to self-service the review process, improving productivity while maintaining accuracy.
3Adaptability or versatility
If remote designers collaborate using traditional methods, then geographic distribution is enabled, but communication difficulties and errors increase
Solution Approach 1:
The patent introduces a computer-based feedback display system as a universal intermediary that all remote designers access through their respective computers. This intermediary standardizes the feedback communication process, eliminating geographic barriers while maintaining high accuracy through automated display and association of comments with specific layout elements.
Solution Approach 2:
The patent replaces manual communication methods with an automated computer-based system that enables remote designers to view and interact with feedback comments directly on the graphical layout. This substitution eliminates communication difficulties associated with remote collaboration while maintaining accuracy through automated processes.
4Quantity of substance
If design review feedback is displayed away from the layout, then feedback can be recorded, but the feedback becomes difficult to associate with specific components
Solution Approach 1:
The patent transitions feedback display from a two-dimensional text-based format to a graphical dimension where comments are displayed directly on or near the corresponding layout elements. This dimensional change maintains the quantity of feedback information while dramatically improving the ease of associating comments with specific components through visual proximity and graphical context.
Data Source
AI summary
A design tool for printed circuit boards displays a graphical representation of a printed circuit board layout through a graphical user interface (GUI). Comments for particular components of the printed circuit board layout can be entered through the graphical user interface. The comments are stored in a data file associated with the printed circuit board layout. Comments can be entered and viewed by multiple users in real time. Comments can be displayed through the graphical user interface in proximity to the component associated with the comment, thereby improving the efficiency with which designers can review and implement suggested changes to the PCB layout.
