Vehicle Lamp Actuator Mounting via Shared Circuit Board
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing illumination devices for vehicles face high costs in mounting and making contact with the actuating unit due to complex integration processes.
Innovation Solution
The actuating unit's drive apparatus is connected to a circuit board within the illumination device, allowing both the drive apparatus and the functional module to share an electrical connection, reducing the need for separate wiring and simplifying the mounting process through mechanical and electrical contacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate wiring harness or cable harness is used to connect the actuating unit to the electrical system, then the electrical connection is reliable, but the mounting effort and cost increase significantly
Solution Approach 1:
The patent merges the electrical connection functions by having the circuit board serve both the functional module and the actuating unit. The actuating unit's drive apparatus makes direct contact with the circuit board, eliminating the need for separate wiring harnesses and reducing mounting complexity while maintaining reliable electrical connections.
Solution Approach 2:
The circuit board is designed to perform multiple functions: it controls both the functional module (light sources) and the actuating unit (drive apparatus). This multi-functionality reduces the overall number of electrical connections needed and simplifies the mounting process.
2Adaptability or versatility
If separate circuit boards are used for the functional module and actuating unit, then each module has dedicated control, but the cabling effort and mounting complexity increase
Solution Approach 1:
The patent combines the control functions for both the functional module and actuating unit onto a single circuit board. This reduces device complexity by eliminating separate cabling and mounting operations while maintaining the ability to independently control each module through separate control signals on the same board.
3Ease of operation
If the actuating unit is directly connected to a wiring harness, then the electrical connection is straightforward, but the mounting cost and effort increase
Solution Approach 1:
The patent merges the electrical connection point with the circuit board that is already integrated into the illumination device. The actuating unit connects directly to this existing circuit board, maintaining connection simplicity while eliminating the need for additional wiring harnesses and reducing mounting cost and effort.
