Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle lamps are typically designed for specific functions and locations, making it difficult for a single lamp to perform multiple functions, such as tail, turn signal, and brake functions, due to dedicated circuits and color specifications.
Innovation Solution
A multifunction lamp system with a control circuit, sense resistor, and multiple colored circuits (red, amber, etc.) that can be programmed and controlled via wireless communication to perform various functions based on commands and location information, allowing a single lamp to emit different colors and intensities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicle lamps are designed for specific functions with dedicated circuits and colored lamps, then each lamp can reliably perform its designated function, but it becomes difficult or impossible for a single lamp to perform multiple functions
Solution Approach 1:
The patent implements a multifunction lamp where a single lamp unit can perform multiple functions (tail lamp, turn signal, brake lamp) by integrating multiple colored lamp elements (red, amber, white) and using a control circuit to selectively activate different functions based on received commands, eliminating the need for separate dedicated lamps for each function
Solution Approach 2:
The lamp system uses a control circuit that can dynamically switch between different operating modes (tail, turn signal, brake) based on commands received from the vehicle, allowing the lamp to adapt its function and behavior in real-time rather than being fixed to a single purpose
2Adaptability or versatility
If multiple dedicated lamps are used for different functions, then each function can be reliably performed, but the quantity of lamps and system complexity increases
Solution Approach 1:
The patent combines multiple previously separate lamp functions (tail lamp, turn signal, brake lamp) into a single integrated lamp unit that contains multiple colored lamp elements and a control circuit, thereby reducing the total number of lamps needed while maintaining all required functions
Solution Approach 2:
The multifunction lamp serves as a universal lamp that can perform multiple functions depending on which lamp elements are activated, replacing what would traditionally require multiple separate dedicated lamps
3Quantity of substance
If a single lamp is designed to perform multiple functions, then the number of lamps is reduced, but the control and switching complexity increases
Solution Approach 1:
The patent introduces a control circuit as an intermediary component that manages the complexity of controlling multiple lamp elements. The control circuit receives commands from the vehicle and selectively activates appropriate lamp elements, acting as a mediator between the vehicle's control system and the multiple lamp functions
4Ease of operation
If dedicated circuits are used for each lamp function, then each function can be independently controlled, but the wiring complexity and energy consumption increase
Solution Approach 1:
The patent merges multiple dedicated circuits into a single integrated control circuit that manages all lamp functions. This unified circuit receives commands from the vehicle and selectively activates appropriate lamp elements, reducing the overall wiring complexity and energy consumption compared to having separate dedicated circuits for each function

AI summary
A lamp for a vehicle or other object that includes multiple functions. In one aspect, the lamp includes a first circuit for emitting a first color light (such as red light), and at least a second circuit for emitting a second color of light (such as amber light). In another aspect, the lamp optionally includes a microcontroller that may be programmed to control the activation of the different colored lamp circuits based on lamp location information, and based on an operating mode.
