Solution Overview

Problem

Existing alternators for motor vehicles do not provide aesthetic illumination effects within the engine compartment, limiting customization options and appearance enhancement.

Innovation Solution

Integration of light-emitting diodes (LEDs) or other illumination devices within the alternator frame, driven by the engine belt, which emit light through vents or are reflected by internal surfaces to create visually appealing effects, with options for various colors, patterns, and activation sequences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If an illumination device is integrated into the alternator, then aesthetic appearance is improved, but device complexity increases

Engineering Contradiction:

Improveaesthetic appearanceVSAvoiddevice complexity

Core Design Contradiction:

ShapeVSDevice complexity

Solution Approach 1:

The illumination device is integrated into the alternator housing, merging two separate functions (power generation and aesthetic illumination) into a single component. This eliminates the need for separate mounting brackets, wiring harnesses, and control systems that would otherwise be required for standalone illumination devices.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The alternator is transformed into a multi-functional component that simultaneously performs its primary function of generating electrical power and provides aesthetic illumination through integrated LED devices. This universal approach allows a single component to serve multiple purposes, reducing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If light emitting diodes are added to the alternator, then customization options are improved, but manufacturing complexity increases

Engineering Contradiction:

Improvecustomization optionsVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The illumination system is segmented into modular LED components that can be independently selected and configured. Different colors, patterns, and activation sequences can be chosen without affecting the core alternator manufacturing process, allowing customization at the component level rather than requiring complete redesigns.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Specific areas of the alternator housing are designated for LED placement and light emission, allowing customization of illumination characteristics in localized regions. This enables different colors and patterns to be implemented in specific zones without complicating the overall manufacturing process.

Inventive Principle:

Principle #3Local quality

3Shape

If illumination devices are integrated into the alternator, then aesthetic appearance is improved, but use of energy increases

Engineering Contradiction:

Improveaesthetic appearanceVSAvoiduse of energy

Core Design Contradiction:

ShapeVSUse of energy by moving object

Solution Approach 1:

Light-emitting diodes (LEDs) are used as the illumination source because they consume minimal energy compared to traditional lighting devices. LEDs are designed to operate at low power levels, drawing only small amounts of energy from the alternator's electrical output, thus having negligible impact on the vehicle's overall energy consumption.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The illumination devices can be configured to operate periodically or intermittently rather than continuously, further reducing energy consumption. Different activation sequences and patterns allow the system to provide aesthetic illumination only when needed, such as when the vehicle is stationary or during specific operational conditions.

Inventive Principle:

Principle #19Periodic action

AI summary

An illuminated alternator for automotive and other motorized vehicles includes a plurality of illumination devices, such as light emitting diodes, bulbs or lasers. The illumination devices are positioned within the alternator. When the illumination devices are activated, light from the illumination devices is reflected by surfaces of the alternator frame and exits the alternator frame through one or more vents, thus providing a glowing or illumination effect that radiates from within the alternator. Different numbers and colors of illumination devices may be used, including illumination devices that emit red, yellow, green and blue light. Illumination devices can also be activated in different sequences and patterns, such as periodically, intermittently, and randomly. An alternator may have illumination devices that are the same or different colors. Illumination devices that are simultaneously active may emit colors that are mixed so that the illumination effect is a color that is different than the colors of the illumination devices.
