Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor systems installed in vehicles face limitations in enhancing information detecting capability due to constraints imposed by the shape of the lamp housing and the layout of the lamp unit.
Innovation Solution
A sensor system configuration that includes a sensor unit disposed outside the lamp housing, an actuator to change the position and posture of the sensor unit, and a processor to control the actuator, thereby increasing the degree of freedom for adjusting the sensor unit's position and posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sensor unit is mounted inside the lamp housing, then the device complexity is reduced and ease of manufacture is improved, but the adaptability and degree of freedom for changing sensor position and posture are limited
Solution Approach 1:
The sensor unit is designed to be movable relative to the lamp housing through an actuator mechanism, transforming from a static fixed mounting to a dynamic adjustable system. This allows the sensor to change its position and posture according to detection needs while maintaining integration with the lamp housing structure.
Solution Approach 2:
The sensor system is divided into separable components: the sensor unit that can be moved, the actuator for movement control, and the lamp housing as mounting base. This segmentation allows independent optimization of each component while maintaining overall system functionality.
2Measurement precision
If multiple sensors are mounted on the vehicle to expand detection area, then the information detecting capability is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The sensor unit mounted on the lamp housing serves dual purposes: it functions as part of the lighting system integration while simultaneously providing detection capabilities. This multi-functionality reduces the need for separate dedicated sensor mounting structures, simplifying manufacturing.
Solution Approach 2:
The sensor unit is integrated with the lamp housing structure, combining the lighting and sensing functions into a unified system. This merging reduces the total number of separate components and simplifies the manufacturing process compared to completely separate sensor mounting systems.
3Area of stationary object
If the sensor unit position is fixed, then the device complexity is reduced, but the ability to expand detection area and enhance information detecting capability is limited
Solution Approach 1:
The sensor unit transitions from a fixed position to a dynamically adjustable position through the actuator system. This dynamic capability allows the detection area to be expanded and repositioned as needed while the processor provides intelligent control to manage the complexity of the actuation system.

AI summary
A sensor unit is disposed outside a lamp housing of a vehicle to detect information in an outside area of the vehicle. An actuator is configured to be able to change at least one of a position and a posture of the sensor unit with respect to the lamp housing. A processor is configured to control an operation of the actuator.
