Solution Overview

Problem

Users often inaccurately position secondary displays with respect to primary displays during configuration, leading to inefficient and time-consuming setup processes.

Innovation Solution

A processor tracks the movement of a cursor from a primary display to an icon on a secondary display to determine its position, using horizontal and vertical distances and angles to accurately calculate the secondary display's location relative to the primary display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If users manually configure secondary display locations, then configuration flexibility is maintained, but setup time and user effort increase significantly

Engineering Contradiction:

Improvesetup timeVSAvoidconfiguration effort

Core Design Contradiction:

Loss of timeVSEase of operation

Solution Approach 1:

The system automatically determines secondary display locations by tracking cursor movements and calculating geometric relationships, eliminating the need for users to manually configure display positions. The computing device performs self-configuration by processing cursor trajectory data to infer spatial relationships between displays.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical configuration operations with automated computational methods. Instead of users physically positioning display icons based on visual estimation, the system uses cursor movement tracking and mathematical calculations to automatically determine display locations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If automatic cursor tracking is implemented to determine display location, then positioning accuracy improves, but processing complexity increases

Engineering Contradiction:

Improvedisplay location accuracyVSAvoidprocessing complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent extracts only the essential cursor movement data needed for location determination, focusing on start and end positions rather than tracking every cursor coordinate. This selective data extraction reduces processing complexity while maintaining positioning accuracy.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system performs preliminary calculations by establishing coordinate systems and transformation relationships before final display positioning. By pre-defining geometric models and calculation frameworks, the complex positioning task is broken into manageable sequential steps.

Inventive Principle:

Principle #10Preliminary action

AI summary

According to examples, an apparatus may include a processor that may, responsive to a determination that a secondary display is connected to the apparatus, cause a primary display of the apparatus to display a window including an option to be selected to proceed with a location detection operation of the secondary display. The processor may also cause an icon to be displayed on the secondary display, track a movement of a cursor from the primary display to the icon displayed on the secondary display, and determine a position of the secondary display with respect to the primary display based on the tracked movement of the cursor. The processor may further store the determined position of the secondary display with respect to the primary display.
