Solution Overview

Problem

Current vehicle rear combination lamps lack the ability to dynamically adjust their styling and information delivery based on driving conditions, weather, and user preferences without requiring physical replacement, and they do not effectively communicate with external systems for real-time data integration.

Innovation Solution

A vehicle rear combination lamp system featuring a display with multiple light-emitting devices controlled by a processor that adjusts styling and intensity based on driving conditions, weather, and user input, and includes an interface to receive external data for real-time information display, such as distance to following vehicles and traffic laws, using OLEDs and communication units for connectivity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed design rear combination lamp is used, then manufacturing simplicity is maintained, but adaptability to different styling preferences and driving conditions deteriorates

Engineering Contradiction:
Improvestyling adaptabilityVSAvoidlamp system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rear combination lamp incorporates a display device that can dynamically change its appearance and information display based on driving conditions, weather, and user preferences. The processor controls the display to present different exterior style images and adjust light intensity, transforming a static lamp into a dynamic, adaptable system that resolves the contradiction between fixed design simplicity and styling versatility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes multiple parameters including light intensity (adjusted based on driving environment and weather), display content (different exterior style images selected by processor), and information display (distance to following vehicles, traffic laws). These parameter changes enable the lamp to adapt to various conditions while maintaining a single physical device, thus improving adaptability without requiring multiple different lamp designs.

Inventive Principle:
Principle #35Parameter changes

2Illumination intensity

If light intensity is increased for better visibility, then information delivery to other vehicles improves, but energy consumption increases

Engineering Contradiction:
Improvelight intensityVSAvoidenergy consumption
Core Design Contradiction:
Illumination intensityVSUse of energy by moving object

Solution Approach 1:

The processor dynamically adjusts the light intensity parameter based on driving environment and weather conditions. The system sets maximum and minimum intensity values and controls the light emitting devices to output light within this range, optimizing visibility while managing energy consumption. This resolves the contradiction by making light intensity adaptive rather than fixed at high levels.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The rear combination lamp transitions from static light emission to dynamic intensity control, where the processor continuously adjusts light output based on real-time conditions such as weather, driving environment, and distance to following vehicles. This dynamic adjustment enables the system to provide sufficient visibility only when necessary, reducing overall energy consumption while maintaining effective information delivery.

Inventive Principle:
Principle #15Dynamics

3Loss of information

If multiple lamp bodies are controlled individually, then information delivery precision improves, but device complexity increases

Engineering Contradiction:
Improveinformation delivery precisionVSAvoidcontrol system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The display device serves multiple functions: it provides exterior styling, delivers information to other vehicles, adjusts based on driving conditions, displays distance to following vehicles, and presents traffic law information. By consolidating these multiple functions into a single multi-functional display system controlled by one processor, the patent achieves precise information delivery without proportionally increasing control system complexity.

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

Solution Approach 2:

The patent merges multiple lamp functions (exterior styling, information display, adaptive lighting) into a single integrated rear combination lamp system. The processor combines control of light emitting devices, display content, and intensity adjustment into one unified control mechanism, achieving precise information delivery while avoiding the complexity of entirely separate control systems for each function.

Inventive Principle:
Principle #5Merging (Combining)
