Solution Overview

Problem

As the amount of digital content increases, it becomes increasingly difficult to provide users with an appealing and efficient way to navigate and discover related items, leading to cognitive overload and lack of context in content presentation.

Innovation Solution

A dynamic ingress bar (DIB) that dynamically updates based on user interactions, providing a compact and organized interface to present related items within collections, personalized to user preferences, and reducing the need for additional searches or clicks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If users navigate through traditional search result pages with increasing content volume, then more content is available, but user cognitive load and navigation difficulty increase

Engineering Contradiction:
Improvecontent volumeVSAvoidnavigation difficulty
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent segments the interface into multiple functional zones: a persistent ingress bar that maintains search context, a main content area displaying search results, and a sidebar or overlay that shows collection information. This segmentation allows users to access different types of information simultaneously without overwhelming the interface, resolving the contradiction between providing extensive content and maintaining ease of navigation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a spatial dimension to content organization by displaying collection information in a sidebar or overlay region adjacent to the main search results. This dimensional addition allows users to explore related content collections without navigating away from the current search results, effectively increasing content accessibility while maintaining simple navigation.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Quantity of substance

If traditional search interfaces present all available content, then completeness is improved, but screen space efficiency deteriorates

Engineering Contradiction:
Improvecontent completenessVSAvoidscreen space usage
Core Design Contradiction:
Quantity of substanceVSArea of stationary object

Solution Approach 1:

The patent extracts collection information from the main search results view and presents it in a separate sidebar or overlay region. This extraction allows the main content area to remain focused on search results while collection details are accessed in a dedicated side space, achieving content completeness without compromising screen space efficiency for primary search functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements a nested interface structure where collection information can be displayed in a compact sidebar that nests within the overall interface layout. When users need detailed collection information, it appears in a nested panel that does not displace the main search results, allowing both search content and collection content to coexist efficiently within limited screen space.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Adaptability or versatility

If dynamic content updates are implemented based on user interactions, then personalization is improved, but system complexity increases

Engineering Contradiction:
Improvecontent personalizationVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements feedback mechanisms where the system monitors user interactions with search results and dynamically updates the ingress bar and collection displays based on observed behavior. This feedback loop enables personalization by adapting content presentation to user preferences while using established interaction patterns that manage system complexity through predictable, rule-based adaptations rather than complex algorithms.

Inventive Principle:
Principle #23Feedback

AI summary

User interactions may be used to recognize a user's intent and provide a dynamic ingress bar (DIB) that carries forward relevant search information for the user. User interactions provide hints for the DIB to populate a collections area including items that have a common theme with the hint. The DIB is provided along with the user's selection so that the user can quickly recognize how their selection is associated with the collection and also continue navigating through a site without backtracking. As the user interacts with additional content, a new user intent may be determined to update the hint and repopulate the collections area based on the updated hint.
