Dynamic UI Item Rendering in Space-Constrained Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for rendering digital content in space-constrained online containers are inefficient, leading to excessive resource consumption and inaccurate indication of overflowing content, as they often require repetitive rendering and hard-coding of item numbers, causing distortions and inefficient use of space.
Innovation Solution
A client system dynamically renders content by determining the maximum number of items that fit within the container's dimensions, using a non-repetitive DOM to display both visible and hidden items, and only showing a call-to-action button when necessary, thereby optimizing resource use and providing accurate overflow indications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a pop-up window is used to display overflowing content, then the user can view all content, but other existing content shifts in the user interface
Solution Approach 1:
The patent implements a nested structure where the overflow container is placed inside the main container. When overflow occurs, the nested container expands to display additional content without causing the main container or other elements to shift. This nesting approach allows overflowing content to be viewed while maintaining the stability of the overall user interface layout.
2Loss of information
If content is rendered twice (once in main container, once in pop-up), then all content is accessible, but computer resources are wasted
Solution Approach 1:
The patent merges the rendering process by creating a single overflow container that is populated with content from the main container. Instead of rendering content separately in a pop-up window, the system combines both views into one unified structure where the overflow container shares the same rendering context and data source as the main container, eliminating redundant rendering operations.
Solution Approach 2:
The system performs preliminary actions by pre-calculating which content will overflow and pre-positioning it in the overflow container. This allows the system to determine overflow status in advance and prepare the overflow content accordingly, avoiding the need for repeated rendering when the user interacts with the interface.
3Device complexity
If hard-coded item numbers are used, then the rendering process is simple, but space utilization is inefficient
Solution Approach 1:
The patent implements dynamic determination of the number of items to display by calculating based on the actual dimensions of the container and the content items. Instead of using hard-coded values, the system dynamically adjusts the item count to maximize space utilization while ensuring all items fit properly. This dynamic approach allows the interface to adapt to different screen sizes and content configurations.
Solution Approach 2:
The system changes the parameter of item count from a fixed hard-coded value to a dynamic calculated value based on container dimensions and item properties. This parameter change enables the system to optimize space utilization by adjusting the number of displayed items according to the available space, rather than using a predetermined number that may waste or insufficiently utilize the container area.
Data Source
AI summary
A machine for dynamic content rendering in a space-constrained online container. The machine accesses a plurality of items of digital content. The machine dynamically renders the plurality of items in a dedicated area of a user interface. The dynamic rendering includes: dynamically determining, for display in the dedicated area, a first item group of one or more items of the plurality of items; causing display of the first item group in the dedicated area; and dynamically determining a second item group of one or more items of the plurality of items. The items included in the second item group are associated with a hidden style based on dynamically determining that the dynamic rendering of the items included in the second item group overflows the dedicated area. The machine dynamically renders a call-to-action button in the dedicated area. The call-to-action button indicates the number of items in the second item group.
