Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Personal GPS navigation devices display menu information alongside map data, which can be distracting and unsafe for users traveling at high speeds, as it tempts them to interact with the device while driving, potentially leading to accidents.

Innovation Solution

A method and device that automatically adjust the display by hiding menu information and enlarging the map area when the device's speed exceeds a threshold, ensuring safety by minimizing distractions and maximizing map visibility during high-speed travel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If menu information is displayed alongside map data, then users can access navigation controls and options, but the display area for the map is reduced and users may be distracted while traveling at high speeds

Engineering Contradiction:

Improveaccess to navigation controlsVSAvoidmap display area

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

The display layout is made dynamic by automatically adjusting between full menu display, partial menu display, and hidden menu states based on the detected speed of the portable electronic device. When speed exceeds the threshold, the menu information is hidden or minimized to maximize map display area; when speed is below the threshold, the menu is fully displayed for ease of operation.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If menu information is displayed while traveling at high speed, then users can access controls, but user safety is compromised due to distraction and temptation to interact with the device

Engineering Contradiction:

Improveaccess to menu optionsVSAvoiduser distraction and safety risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system changes the display parameter (menu visibility) based on the speed parameter. When the detected speed exceeds the predetermined threshold, the menu information is automatically hidden or minimized to eliminate distraction and safety risks associated with high-speed interaction. This parameter change ensures user safety while maintaining operational capability when safe.

Principle #35Parameter changes

3Adaptability or versatility

If the display shows both map data and menu information, then comprehensive navigation functionality is provided, but the map area is insufficient for better navigation visibility

Engineering Contradiction:

Improvenavigation functionalityVSAvoidmap display area

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The display is segmented into functional zones that can be dynamically adjusted. The menu information occupies minimal space (such as a condensed bar at the edge of the display) when needed, while the majority of the display area is dedicated to the map. This segmentation allows both navigation functionality and map visibility to coexist effectively.

AI summary

A method of adjusting a map area displayed on a portable electronic device includes displaying a map of a current location of the portable electronic device on a display of the portable electronic device, calculating a current speed of the portable electronic device, and adjusting data shown on the display by hiding menu information and increasing a size of the displayed map when the current speed of the portable electronic device is greater than a threshold value.
