Solution Overview

Problem

Modern audio control devices in vehicles require complex operation due to the need for visual attention, which complicates manual actions and affects visual aesthetics when using touch-sensitive elements.

Innovation Solution

A selection controller with a selecting element that can be manually operated in two positions – flush with the control surface for aesthetic preservation and raised for user interaction – utilizing a moving device for automatic, controllable transitions between positions, enhanced by an electronic control unit and sensor for intuitive operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If touch-sensitive elements are used for audio control, then visual aesthetics are improved, but ease of operation deteriorates due to requirement of visual attention

Engineering Contradiction:
Improvevisual aesthetics of control surfaceVSAvoidease of operation
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

The selecting element transitions from a static flush-mounted design to a dynamic configuration where it can automatically raise and lower based on detected user proximity or interaction state. This dynamic adjustment allows the control surface to maintain aesthetic appeal when idle while becoming tactilely accessible when needed

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

A sensor system acts as an intermediary between the user and the selecting element, detecting user presence or gestures and automatically triggering the mechanical response. This intermediary enables hands-free or gesture-based operation without requiring visual attention

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If visible switches are used for manual operation, then ease of operation is improved, but visual aesthetics deteriorate due to visible control elements

Engineering Contradiction:
Improveease of operationVSAvoidvisual aesthetics of control surface
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The selecting element is extracted from the control surface plane, creating a raised tactile feature that provides mechanical operability while remaining visually integrated. The element can be recessed or illuminated to minimize visual impact while maintaining functional accessibility

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If the selecting element is always raised for easy operation, then ease of operation is improved, but visual aesthetics deteriorate due to disturbance of control surface

Engineering Contradiction:
Improveease of operationVSAvoidvisual aesthetics of control surface
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The selecting element's position is dynamically adjusted based on operational context. When not in use, it remains flush with the control surface for aesthetic purposes. When activation is detected through sensors or user interaction, it raises to provide tactile feedback and mechanical operability

Inventive Principle:
Principle #15Dynamics

AI summary

A selection controller for manual selection of an operating mode and/or operating characteristics of an audio control device is disposed within an interior of a vehicle. The selection controller includes a selector element that is designed to allow a user to make the manual selection. The selecting element can be arranged at least in a first position that is not elevated from a control surface of the audio control device and in a second position that is elevated from the control surface of the audio control device.
