Solution Overview

Problem

In vehicle AVN systems, users must visually identify menu items on screens, leading to distracted driving due to the need to view the screen, and existing solutions fail to provide efficient methods for selecting menu items without visual attention.

Innovation Solution

A manipulation control apparatus that uses varying click sensations, such as audible or tactile feedback, to indicate the number of menu items on the screen, allowing users to select items without looking at the screen by determining the number of menu items and providing corresponding click sensations through a manipulation unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If users visually identify menu items on the screen, then selection accuracy is improved, but driving safety deteriorates due to distracted driving

Engineering Contradiction:

Improvemenu item selection accuracyVSAvoiddriving safety

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The system provides audible click sensations that give feedback about the number of menu items on the screen. When users rotate the manipulation unit, they hear clicks that correspond to the total number of menu items, allowing them to understand the selection context without visual attention. This feedback mechanism enables accurate menu selection while maintaining driving safety.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If the number of menu items on the screen increases, then system functionality is improved, but user selection time increases

Engineering Contradiction:

Improvesystem functionalityVSAvoidmenu item selection time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The click sensation provision unit provides immediate audible feedback when users rotate the manipulation unit, indicating progress through the menu items. This feedback allows users to quickly understand how many items remain to be scrolled through, enabling faster navigation even when numerous menu items are present, thus reducing selection time while maintaining comprehensive system functionality.
