Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional electronic devices with accessibility functions for visually impaired users face inefficiencies when updating menu lists, causing repeated broadcasts of existing menus and hindering quick traversal of newly added menus, leading to a poor user experience.

Innovation Solution

The method involves updating the menu list by setting a focus menu in the new list based on the old list, ensuring newly added menus are not displayed before the focus menu, and sorting menus according to a service sorting rule to maintain order and reduce repeated broadcasts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the menu list is updated by inserting newly added menus in the middle of existing menus, then the menu list can be updated with new content, but previously broadcast menus are repeatedly broadcast causing slow traversal speed

Engineering Contradiction:

Improvemenu list update capabilityVSAvoidtraversal speed

Core Design Contradiction:

Adaptability or versatilityVSSpeed

Solution Approach 1:

The patent segments the menu list into two distinct parts: newly added menus and existing menus. By separating these segments and positioning newly added menus after the focus menu, the system avoids mixing new and old content in a way that causes repeated broadcasts, thereby maintaining fast traversal speed while enabling menu list updates.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary positioning of newly added menus by determining their placement relative to the focus menu before broadcasting occurs. This preliminary action ensures that newly added menus are strategically positioned after the focus menu, preventing them from interrupting the broadcast sequence of existing menus and avoiding repeated broadcasts.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If the user continues to traverse the updated menu list by sliding down the user interface, then all menus can be accessed, but previously broadcast menus are repeatedly broadcast causing poor user experience

Engineering Contradiction:

Improvemenu traversal operationVSAvoidtime for repeated broadcast

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent segments the menu list into newly added menus and existing menus, with newly added menus positioned after the focus menu. This segmentation ensures that when users traverse the menu list, the system can quickly locate and broadcast only the newly added content without re-broadcasting existing menus, reducing time loss and improving user experience.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary positioning of newly added menus relative to the focus menu before user traversal begins. This preliminary action enables the system to optimize the broadcast sequence, allowing users to access new content efficiently without experiencing repeated broadcasts of previously shown menus.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If newly added menus are arranged in the middle of existing menus, then the menu list is updated, but the electronic device cannot quickly traverse the menu list

Engineering Contradiction:

Improvemenu list updateVSAvoidtraversal efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent segments the menu list into distinct portions: newly added menus and existing menus. By positioning newly added menus after the focus menu rather than in the middle, the system maintains a clear structure that enables quick traversal. The segmentation allows the electronic device to efficiently navigate to and broadcast new content without disrupting the established sequence of existing menus, thereby maintaining high productivity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary positioning of newly added menus relative to the focus menu before traversal occurs. This preliminary action establishes an optimal structure where newly added menus are placed after the focus menu, enabling the electronic device to quickly traverse to new content without having to search through or re-broadcast existing menus, thus maintaining high traversal efficiency.

Inventive Principle:

Principle #10Preliminary action

AI summary

A menu list update method is provided. In the method, for an updated menu list, when an electronic device displays the menu list, a newly added menu in the menu list is always displayed after a focus menu. The technical solution provided in this application is implemented, so that the electronic device can quickly traverse the menu list. In this way, a visually impaired user can quickly find an expected menu. This improves user experience of the visually impaired user on the electronic device.
