PBX Extension Selection via Hierarchical Graphical Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic connection methods for calls to private branch exchanges (PBX) are inefficient, requiring multiple selections and potentially leading to frustration if the wrong alternative is chosen, necessitating a restart of the process.
Innovation Solution
A graphical display of alternatives allows users to select an extension positioned multiple steps down in a hierarchy, enabling faster information processing and access to further information, with the ability to traverse the hierarchy and choose multiple extensions with priority settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple selection steps are used to connect to extensions, then more connection alternatives are offered, but the call establishment process becomes more complex and time-consuming
Solution Approach 1:
The extension list is segmented into multiple levels of hierarchy, where each level represents a category or group of extensions. Users can navigate through these segmented levels to find desired extensions, allowing the system to offer more connection alternatives while organizing them in a manageable structure that reduces the complexity of the selection process.
Solution Approach 2:
The patent introduces a hierarchical dimension to the extension selection process, organizing extensions across multiple levels rather than a flat list. This dimensional change allows the system to present numerous connection alternatives in an organized hierarchy, enabling users to navigate and select extensions more efficiently without feeling overwhelmed by the complexity.
2Adaptability or versatility
If multiple selection steps are required, then more connection alternatives are provided, but the time to establish the call increases
Solution Approach 1:
The system performs preliminary actions by pre-organizing extensions into a hierarchical structure and providing visual displays of alternative connections. This preliminary organization allows users to quickly navigate and select extensions without having to go through multiple sequential selection steps, thereby reducing call establishment time while still providing numerous connection alternatives.
Solution Approach 2:
The patent employs visual displays that replicate or represent the hierarchical structure of extensions in a user-friendly format. These visual copies of the extension hierarchy allow users to quickly perceive and select from multiple connection alternatives without having to navigate through complex multi-step processes, thus reducing the time required to establish calls.
3Adaptability or versatility
If sequential selection steps are used, then connection alternatives are offered step-by-step, but user frustration increases due to repeated selections
Solution Approach 1:
The patent introduces visual displays as intermediaries between the system and the user. These displays present connection alternatives in a hierarchical visual format, serving as a mediator that helps users quickly understand and select from multiple options without having to go through repetitive sequential steps, thereby improving ease of operation while maintaining numerous connection alternatives.
Solution Approach 2:
By organizing connection alternatives into a hierarchical dimension with visual displays, the system presents multiple options in a structured, easily perceivable format. This dimensional organization reduces the cognitive load on users and eliminates the frustration of repeated selections, as users can quickly navigate and select from alternatives presented in a clear hierarchical structure.
