Solution Overview

Problem

In pickup-type motor vehicles, managing stop and cargo light functions requires three separate devices and power supplies, leading to increased component count and assembly time.

Innovation Solution

A unified light management device with a common power supply, stabilized reference voltage, and switching blocks for each light function, allowing prioritization and reduction of components and assembly time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If three separate managing devices and power supplies are used for stop and cargo light functions, then each light function can be independently controlled, but the number of components and assembly time increase

Engineering Contradiction:

Improveindependent control of light functionsVSAvoidnumber of components

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges multiple separate managing devices and power supplies into a single integrated managing device that controls both stop and cargo light functions. This consolidation reduces the number of components while maintaining independent control capability through internal switching mechanisms and control circuits that can selectively activate different light functions based on operational requirements.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The managing device is designed with multi-functionality to handle both stop light and cargo light operations through a single unit. The device incorporates multiple switching blocks and control circuits that can independently manage different light functions, allowing one device to perform the work of what would traditionally require separate dedicated devices for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If three separate managing devices are used for stop and cargo light functions, then each function has dedicated control, but assembly time increases

Engineering Contradiction:

Improvededicated control for each functionVSAvoidassembly time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

By consolidating multiple managing devices into one integrated unit, the patent reduces assembly operations while maintaining dedicated control pathways for each light function. The single device incorporates internal switching blocks and control circuits that provide function-specific control without requiring separate external devices, thereby reducing assembly time while preserving reliability.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A device for managing at least two light functions accommodated in a same motor vehicle light device, the managing device comprising a block of light sources for each light function, wherein the managing device further comprises: an input block configured to: provide a power supply common to the at least two light functions; indicate if the at least two light functions are activated or deactivated; a bias block configured to supply a stabilized reference voltage common to the at least two light functions; a switching block for each light function, one switching block of which is configured to deactivate one of the at least two light functions that is defined as secondary with respect to the other of the at least two light functions that is defined as having priority if the latter is activated.
