Solution Overview

Problem

Existing card display methods on electronic devices are limited in the amount of information they can display and compromise user privacy by revealing personal information.

Innovation Solution

A card display method that allows users to create cards with multiple folder icons on the desktop, enabling quick access to various folders, and includes customizable options for adding, editing, and removing cards, while displaying folder information instead of specific file details to maintain privacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If specific file information is displayed on cards, then users can view detailed file content, but user personal information is leaked

Engineering Contradiction:
Improvefile information visibilityVSAvoidprivacy leakage
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent extracts only the essential folder identification information from the file details, displaying folder names and icons while deliberately excluding specific file content and personal information. This allows users to identify and access folders without exposing sensitive file data, thus resolving the contradiction between information visibility and privacy protection.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies different levels of information disclosure to different elements on the card. Folder identifiers (names and icons) are displayed with full visibility for easy identification, while specific file information is either hidden or displayed in a condensed, anonymized format. This local differentiation of information quality allows the system to provide necessary folder access information while protecting sensitive file-level personal information.

Inventive Principle:
Principle #3Local quality

2Quantity of substance

If traditional card display methods are used, then the interface is simple, but the amount of displayed information is limited

Engineering Contradiction:
Improveamount of information displayedVSAvoidcard structure complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent implements a nested structure where multiple folder icons are contained within a single card element. Each card can host multiple folder representations, and users can expand or collapse these nested folders to reveal or hide their contents. This nesting approach allows the system to display a large amount of folder information within a compact card interface, increasing information density without proportionally increasing interface complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent segments the card display into multiple functional zones: a header area for card identification, a body area containing multiple nested folder icons arranged in a grid or list format, and a footer area for interaction controls. This segmentation allows the card to organize and display extensive folder information in a structured, manageable layout that maintains visual clarity while accommodating large amounts of content.

Inventive Principle:
Principle #1Segmentation

AI summary

The present application provides a card display method, an electronic device, and a computer-readable storage medium, and relates to the field of information display technologies. Through the proposal of the present application, cards of various specifications on the desktop are provided for users to choose. For example, a card on the desktop provides a common folder path customizable by a user, and/or a card on the desktop can support scrolling switching display of recently processed files. Users can choose to add cards suitable for their own usage habits to the desktop for display according to actual usage needs. Since a card on the desktop presents a folder form or a file name to the user, instead of specific file information, user personal information is not leaked. When needed, the user only needs to open the folder in the card on the desktop to view corresponding information, or simply slide the card on the desktop to intuitively view all the files recently used on the electronic device, which can display a large amount of information and is convenient, quick, and secure.
