Rotatable Lamp Assembly with Integrated Sensor for Blind Spot Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial vehicles face challenges in detecting blind spots due to limited rear viewing areas and the difficulty in mounting sensors, especially on vehicles with three-side loading doors or trailers, where traditional methods do not apply.
Innovation Solution
A lamp assembly with a built-in sensor is designed, featuring a rotatable configuration that allows the lamp with the sensor to adjust its direction relative to a rear lamp, enabling effective blind-spot detection by positioning sensors to face lateral sides and automatically adjusting detection areas based on vehicle turns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate rear detection sensor is mounted on the vehicle, then blind spot detection capability is improved, but device complexity and mounting difficulty increase due to limited rear viewing area and various mounting conditions
Solution Approach 1:
The sensor is integrated into the lamp assembly structure, combining the lighting function and detection function into a single component. This eliminates the need for separate sensor mounting and reduces overall system complexity while maintaining detection capability.
Solution Approach 2:
The lamp assembly serves multiple functions: it provides illumination through the light guide and simultaneously performs blind spot detection through the integrated sensor. This multi-functionality reduces the number of separate components needed on the vehicle.
2Volume of moving object
If a sensor is disposed with the vertical lamp on a pickup truck, then space utilization is improved, but adaptability decreases because this method cannot be applied to light trucks or trailer vehicles with three-side loading doors
Solution Approach 1:
The lamp assembly incorporates a rotatable mechanism that allows the lamp and sensor to change their orientation dynamically. This enables the same lamp assembly to be adapted to different vehicle types and mounting positions, including vehicles with three-side loading doors where vertical lamps cannot be placed.
3Measurement precision
If the sensor is placed in the lamp housing ahead of the inner glass, then detection effectiveness is improved by positioning the sensor in optimal locations, but the lamp structure becomes more complex
Solution Approach 1:
The sensor is integrated within the existing lamp housing structure rather than being mounted separately. This utilizes the already-present structural elements of the lamp assembly to support the sensor, minimizing additional structural complexity while achieving optimal sensor positioning for detection effectiveness.

Function Achieved in This Case
This solution allows for efficient detection of surrounding objects and towed vehicles, even in limited spaces, by ensuring sensors can be placed without wasting space and effectively covering blind spots, enhancing safety and operational efficiency.
Implementation Method 1
a light guide that is disposed on an inside surface of the lamp housing and that emits light
Implementation Method 2
a sensor that is disposed inside the lamp housing and located ahead of the inner glass with respect to the longitudinal direction and that senses a surrounding object
