Solution Overview

Problem

Modern motor vehicle display and control panels lack clarity regarding their operating state and the availability of functions, making it difficult for users to understand when and how to access various vehicle functions during different operating sequences.

Innovation Solution

The integration of a display control logic unit that assigns functions through specified operating sequences, using illuminated display units to provide directional pointers guiding the user through sequential operations, such as an optical waveguide-based light bar indicating the next control unit to be actuated.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If display and control panels are used in modern motor vehicles, then the vehicle functions can be controlled, but the operating state and availability of functions are not clear to users

Engineering Contradiction:
Improveclarity of operating state informationVSAvoidcomplexity of display and control system
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent applies illumination changes to display units and control elements to indicate their operational state and availability. Different illumination states (on/off, different colors, different intensities) communicate whether a function is available and whether a control element can be actuated, resolving the information clarity issue without adding complex displays

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent uses sequential illumination patterns where display units and control elements are illuminated in a specific sequence to guide users through operating steps. This periodic activation pattern provides temporal information about the current step and available actions, reducing the need for continuous complex displays

Inventive Principle:
Principle #19Periodic action

2Loss of information

If functions are indicated by random activation of displays or illumination of pushbuttons, then some information is provided, but the operating sequence is not clear to users

Engineering Contradiction:
Improveclarity of operating sequence informationVSAvoidease of understanding operating sequence
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent implements a feedback mechanism where the illumination pattern of display units and control elements responds to the current operating state and guides the user through the correct sequence. The system provides feedback about which controls are available and in what order they should be actuated, making the operating sequence intuitive

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent introduces an intermediary illumination system that mediates between the vehicle's control system and the user. This intermediary layer translates complex operating sequences into simple visual cues through strategic illumination of control elements, guiding users without requiring them to understand the underlying system complexity

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the interior light switches on automatically after unlocking the door, then the lighting function is provided, but other vehicle functions remain inaccessible

Engineering Contradiction:
Improveavailability of vehicle functionsVSAvoiduser awareness of function availability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies local quality by selectively illuminating specific control elements based on their current availability and relevance. Instead of illuminating all controls or using a single ambient light, the system illuminates only those control elements that are currently accessible and relevant to the user's next action, providing localized information about function availability

Inventive Principle:
Principle #3Local quality

AI summary

A motor vehicle, is provided with a plurality of operator control units which can be operated individually by an occupant in order to initiate functions of the motor vehicle, a plurality of display units that can be illuminated, and a display control logic unit. In response to operator activation of a first function associated with a second function in a specified operating sequence, a first display unit can be controlled in such a way that the first display unit displays a directional pointer in the spatial direction of a second operator control unit, which on being actuated can initiate the second function.
