Solution Overview
Problem
Existing vehicle camera modules with integrated signaling lamps require additional wiring and bus system connections to control multiple colored lighting devices independently, increasing complexity and cost, while lacking improved visibility and versatility in light indications.
Innovation Solution
A camera module with a housing containing multiple light sources of different colors, arranged around a lens with specific openings for light passage, and a control circuit that uses input voltage information to control the on/off states of these light sources without needing additional wiring or bus system connections, allowing for independent control of LEDs or LED arrays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separately controllable lighting devices with different colors are used in the camera module, then the versatility in light indications is improved, but additional wiring and bus system connections are required, increasing device complexity
Solution Approach 1:
The patent combines multiple lighting devices with different colors into a single integrated lighting unit within the camera module housing. This merging approach allows multiple colors to be controlled through a single control circuit without requiring separate wiring for each lighting device, thus maintaining versatility while reducing wiring complexity
Solution Approach 2:
The control circuit is designed to universally control multiple lighting devices with different colors through a single interface. This multi-functional control capability allows the system to provide various light indications (turn signals, warning lights, blind spot assistance, welcoming lights) without requiring separate control systems for each function
2Ease of operation
If additional interfaces for voltage supply and bus system connections are introduced to control multiple lighting devices independently, then the control capability is improved, but the costs and complexity of the overall system increase
Solution Approach 1:
The control circuit provides universal control capability for multiple lighting devices through a single interface design. This allows independent control of different colored lights without requiring multiple separate interfaces, maintaining ease of operation while minimizing system complexity
Solution Approach 2:
The control circuit is designed to automatically manage the control signals for multiple lighting devices without requiring additional external control interfaces. The circuit independently handles the switching and timing of different colored lights based on the single control signal it receives, eliminating the need for complex external control systems
