Breadcrumb Control for Hierarchical Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing systems face challenges in efficiently navigating and displaying hierarchical units, requiring users to manually navigate through multiple pages to understand the classification of a selected unit within a complex hierarchy, leading to increased network traffic and processing overhead.
Innovation Solution
A breadcrumb control system is implemented, which generates a user interface control displaying ancestor nodes in the unit hierarchy, allowing users to easily navigate through the hierarchy by selecting links within the breadcrumb control, thereby reducing the need for manual navigation and minimizing data retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If users manually navigate through multiple pages to understand unit classification, then navigation completeness is improved, but user efficiency and system performance deteriorate due to increased network traffic and processing overhead
Solution Approach 1:
The breadcrumb control pre-generates and displays the complete navigation path from the root node to the selected unit before the user needs to navigate. This preliminary action provides all navigation information upfront, eliminating the need for users to manually traverse through multiple pages to understand the unit classification hierarchy.
2Loss of information
If users manually navigate through multiple pages, then navigation completeness is improved, but network traffic and processing overhead increase
Solution Approach 1:
The system pre-generates the breadcrumb control with the complete path information when the detail page is loaded, rather than retrieving data on-demand during user navigation. This preliminary data preparation reduces subsequent network traffic by providing all necessary navigation information in a single upfront operation.
3Ease of operation
If breadcrumb control displays all ancestor nodes, then navigation capability is improved, but interface complexity increases
Solution Approach 1:
The breadcrumb control segments the navigation path into discrete, clickable link elements separated by visual delimiters (such as slashes or angle brackets). Each ancestor node is presented as an independent, interactable unit, making the complex hierarchy manageable and easy to navigate through small, incremental steps rather than overwhelming the user with a monolithic structure.
Data Source
AI summary
A user interaction is detected, selecting a unit with a user input mechanism. A unit hierarchy path that is used to categorize units, is accessed and a node in the unit hierarchy path, corresponding to the selected unit, is identified. A set of ancestor nodes in the unit hierarchy path is also identified, and a user interface breadcrumb control is generated based upon the selected unit and the identified ancestor nodes. A display system is controlled to render a display page for the selected unit, along with the breadcrumb control.
