Solution Overview

Problem

Conventional on-vehicle device operation apparatuses lack clear differentiation between an unresponsive device and an incorrectly pushed operation switch, leading to user confusion and reduced operability.

Innovation Solution

Incorporating a display control part that emphasizes the display of an operation switch with no assigned operation, making it visually distinct when pushed, thereby informing the user that the switch was successfully activated but lacks a defined function.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple operation switches are provided in the operation part, then the functionality and versatility of the device are improved, but the user cannot distinguish between failing to push an operation switch and the device being unresponsive, leading to confusion

Engineering Contradiction:
ImprovefunctionalityVSAvoidoperability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system provides visual feedback by displaying an image of the operation part on the display unit. When a push operation is detected on any operation switch, the system highlights the corresponding switched element in the displayed image, confirming to the user that the operation was registered. This feedback mechanism resolves the confusion between unpushed switches and unresponsive device by providing immediate visual confirmation of the push operation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system uses color or brightness changes in the displayed image to indicate the state of operation switches. When a push operation is detected, the corresponding switched element in the image is emphasized through color or luminance changes, making it visually distinct from other switches. This visual differentiation helps users understand which switch they pressed and confirms the system is responding correctly.

Inventive Principle:
Principle #32Color changes

2Device complexity

If no visual feedback is provided when an operation switch is pushed, then the device complexity is reduced, but the user experiences confusion unable to distinguish between incorrect switch pushing and device unresponsiveness

Engineering Contradiction:
Improvesystem complexityVSAvoidoperational status information
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The system creates a visual copy or representation of the operation part on the display unit. This displayed image serves as a visual record that mirrors the physical switches, allowing users to see which switch corresponds to their push operation. The copy provides operational status information without adding significant physical complexity to the device.

Inventive Principle:
Principle #26Copying

AI summary

An on-vehicle device operation apparatus according to an embodiment includes an operation part, an on-vehicle device control part, and a display control part. The operation part is provided in an inside of a vehicle and includes a plurality of operation switches. When one of the operation switches is pushed, the on-vehicle device control part controls an on-vehicle device depending on the pushed operation switch. The display control part causes a display part to display an image corresponding to the operation part. when a first operation switch with no assigned operation among the plurality of operation switches is pushed, the display control part causes the display part to emphatically display a portion corresponding to the first operation switch in the image corresponding to the operation part.
