Unified Item List Rendering with Selection Markers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computers face challenges in efficiently and scalably presenting a mixed set of selected and unselected items as separate lists while maintaining sort order and priority, often requiring separate data structures that lead to overhead and synchronization issues.
Innovation Solution
Storing items in a single data structure with markers to differentiate selected and unselected items, allowing for efficient rendering of both lists by iterating through the marked items, without the need for separate data structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate data structures are used for selected and unselected items, then the lists can be managed independently, but the system overhead increases and synchronization issues occur
Solution Approach 1:
The patent merges the selection state information into the single item data structure by adding a 'selected' boolean field to each item. This allows the system to maintain one unified data structure instead of separate structures for selected and unselected items, reducing overhead while preserving the ability to independently manage and filter items by their selection state.
2Reliability
If items are moved between separate data structures, then selection status can be updated, but the data structure must be resorted maintaining sort order
Solution Approach 1:
By combining selection state into the item itself rather than managing separate data structures, the patent eliminates the need to resort data when items change selection status. The single data structure maintains its sort order while items can be efficiently filtered and displayed based on their 'selected' property without structural reorganization.
3Device complexity
If a single data structure is used for all items, then overhead is reduced and operations are simplified, but separate list management becomes more difficult
Solution Approach 1:
The patent applies local quality by adding the 'selected' boolean property to each individual item in the data structure. This allows the system to maintain a single unified data structure while enabling local differentiation of items based on their selection state, making it easy to filter and manage selected versus unselected items without needing separate data structures.
4Manufacturing precision
If items are filtered and sorted by multiple criteria (sort order and priority), then the lists can be precisely controlled, but the rendering complexity increases
Solution Approach 1:
By attaching the 'selected' property to each item, the patent enables simple client-side filtering based on this local property. The server can return items sorted by any criteria, and the client can efficiently render selected and unselected lists by filtering items based on their individual 'selected' state, reducing rendering complexity while maintaining precise control over list composition.

AI summary
An item set may comprise items respectively having a selection status, such as a selected item and an unselected item. The item set may be presented as a selected list and an unselected list having various properties (e.g., mutual exclusivity, such that an item appears on at most one list; both lists sorted according to a sort order; and the unselected list having an unselected list size limit, with unselected items appearing in the unselected list based on a priority order). In order to render the selected list and the unselected list, an item list may be generated that attaches to respective items a selected marker (indicating that the item appears in the selected list) or a hidden marker (indicating that the item does not appear in either the selected list or the unselected list), where the item list is also sorted according to the sort order.
