Solution Overview

Problem

Current central instruments in vehicle cockpits lack the ability to effectively enhance the informative value of displayed information, particularly in conveying critical vehicle status and operational efficiency to the driver.

Innovation Solution

A modular central instrument with a circular display that utilizes variable color lighting along its edge to create attention-grabbing light figures and surface effects, which can symbolize vehicle conditions and operational metrics through rhythmic patterns and colors, allowing for dynamic and intuitive feedback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a standard circular display is used for vehicle information, then the design is simple and manufacturing is easy, but the informative value and attention-grabbing capability are insufficient

Engineering Contradiction:
Improveinformative valueVSAvoiddevice complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent applies color changes by implementing a lighting means with multiple color-capable light sources (red, yellow, green, blue, white LEDs) arranged in a ring around the display. The control unit activates specific colors to encode different information types and urgency levels, transforming a simple display into an informative communication system that conveys speed, efficiency, warnings, and instructions through color-coded visual signals.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent implements periodic action through rhythmic lighting patterns where light sources are activated in sequences with specific frequencies and durations. Different rhythmic patterns (continuous, pulsing, alternating) are used to distinguish between various information categories and draw driver attention without causing distraction, creating a temporal dimension to the information presentation.

Inventive Principle:
Principle #19Periodic action

2Adaptability or versatility

If multiple light sources are arranged in a ring to create light figures, then the symbolic communication capability is enhanced, but the device complexity increases

Engineering Contradiction:
Improvesymbolic communication capabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the lighting means into multiple independently controllable light sources arranged in a ring (typically 6-12 LEDs positioned at specific angular intervals). Each light source can be individually activated, dimmed, or colored based on the information being conveyed, allowing for precise control over the light figures and patterns displayed around the circular instrument cluster.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements universality by designing a single ring of multi-color light sources that can perform multiple functions: indicating speed efficiency levels, displaying directional information, conveying warning messages, providing instructional guidance, and creating various symbolic patterns. This multi-functional lighting system replaces what would otherwise require multiple separate indicator systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Loss of information

If rhythmic lighting patterns are used to symbolize vehicle functions, then the driver's situational awareness is improved, but the energy consumption increases

Engineering Contradiction:
Improvesituational awarenessVSAvoidenergy consumption
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

The patent applies partial action by activating only the specific light sources and colors needed to convey the current information state, rather than illuminating all light sources continuously. The system uses selective activation based on the type and urgency of information being communicated, reducing overall energy consumption while maintaining effective situational awareness.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The patent implements periodic action through rhythmic lighting patterns where light sources are activated in sequences with specific frequencies and durations. Different rhythmic patterns (continuous, pulsing, alternating) are used to distinguish between various information categories and draw driver attention without causing distraction, creating a temporal dimension to the information presentation.

Inventive Principle:
Principle #19Periodic action

AI summary

The invention relates to a central instrument in the cockpit of a motor vehicle, comprising a circular display in which multiple items of information are displayed, said items being relevant to the vehicle. The display has an at least approximately circular edge that contains multiple lighting means which are freely programmable with regard to brightness, which are variably controlled during an operating phase of the motor vehicle, and which generate a light figure that varies over time. The light figure provides a determination of the state and/or the function of the motor vehicle and/or a motor vehicle component.
