Solution Overview

Problem

Vehicle-mounted touch panel devices face difficulties in drag operations due to user constraints like seatbelts and vehicle movements, leading to unintentional finger movements and erroneous operations, especially during vehicle stops.

Innovation Solution

A vehicle-mounted information device with an edit mode that uses marks to indicate object movement directions, allowing objects to be interchanged via touch operations on these marks, eliminating the need for drag operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a drag operation is used to rearrange icons on a touch panel, then the operation can be performed on a handheld device, but the operation becomes unreliable in a vehicle-mounted device due to body movement and seatbelt constraints

Engineering Contradiction:

Improveicon rearrangement operationVSAvoidoperation accuracy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The drag operation is segmented into two distinct steps: first selecting an object, then selecting a target position marked by a mark. This segmentation allows each step to be completed with a simple touch rather than requiring a continuous drag gesture, making the operation more reliable in vehicle-mounted environments where finger movement is constrained.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mark indicating the target position is displayed in advance before the user completes the selection. This preliminary display of the mark allows the user to plan and execute the operation in discrete steps, reducing the impact of unintended finger movements during the operation process.

Inventive Principle:

Principle #10Preliminary action

2Device complexity

If a drag operation is used to select and move objects, then the interface can be simple, but unintended finger movements cause erroneous operations

Engineering Contradiction:

Improveinterface simplicityVSAvoidoperation precision

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The selection process is divided into object selection and position selection as separate steps. The mark is displayed to indicate the target position, and the user touches the mark to complete the selection. This segmentation maintains interface simplicity while preventing erroneous operations by requiring intentional two-step confirmation.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If the operation is interrupted when the signal changes during stopping at a red light, then the system responds to external changes, but an unintentional operation is performed

Engineering Contradiction:

Improveresponse to signal changesVSAvoidoperation integrity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The mark indicating the target position is displayed in advance, allowing the user to see the intended destination before completing the operation. This preliminary display ensures that even if the signal changes during operation, the user can verify the intended action and avoid unintentional operations.

Inventive Principle:

Principle #10Preliminary action

AI summary

A vehicle-mounted information device that does not create a cause of an erroneous operation is provided. In a vehicle-mounted information device capable of editing objects 11 to 18 displayed on a touch panel 121, an edit mode of displaying a mark 20 (20a) indicating a direction in which the object 11 is movable is provided, and by a touch operation onto the mark 20 (20a), the selected object 11 and an object 12 of interest which is located in the direction indicated by the mark 20 (20a) are interchanged.
