Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automotive lighting systems require multiple lamps and housings for sequential lighting effects, which are inefficient, difficult to install, and often incompatible with standard lamp sockets, lacking the ability to provide high-efficiency directional lighting across a single housing.
Innovation Solution
A sequential automotive lamp apparatus utilizing at least two directional LEDs that illuminate sequentially through a timer circuit, focused by a directional device, and housed in a single lamp housing, capable of functioning as taillights, turn signals, and running lights, with circuitry that synchronizes the illumination across multiple lamp housings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple separate lamps and housings are used for sequential lighting, then sequential lighting effect is achieved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent combines multiple directional light sources and their control circuits into a single lamp housing that can be installed in a standard automotive socket. This merging of previously separate components (multiple housings, multiple sockets) into one integrated unit directly reduces installation complexity and eliminates the need for multiple housing installations while maintaining the sequential lighting effect.
Solution Approach 2:
The single lamp housing is designed to be universally compatible with standard automotive lamp sockets while providing multiple lighting functions (sequential turn signals, running lights, brake lights) that previously required separate housings. This universal design allows the same housing to replace multiple specialized housings, simplifying installation and reducing device complexity.
2Use of energy by moving object
If incandescent bulbs are used, then compatibility with standard sockets is achieved, but energy efficiency and lifetime are poor
Solution Approach 1:
The patent changes the fundamental parameter of the light source from incandescent bulbs to LEDs (light-emitting diodes). This parameter change dramatically improves energy efficiency as LEDs consume significantly less power, and extends lifetime as LEDs are solid-state devices with no filament to burn out. The directional nature of LEDs also eliminates the need for reflectors and lenses, further improving system efficiency.
3Manufacturing precision
If non-directional lights are used in universal sockets, then socket compatibility is achieved, but lighting precision and control are poor
Solution Approach 1:
The patent employs multiple directional LEDs within a single housing, each oriented to illuminate specific sections of the lamp housing. This local quality approach allows precise control over which areas are illuminated and in what sequence, achieving high lighting precision while maintaining overall socket compatibility through the universal housing design.
