Vehicle NIR Sensor Mounting for Separate Cover Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles equipped with near-infrared sensors and sensor covers, flying pebbles can damage the sensor covers, reducing their transmissiveness, and prolonged use can degrade the sensing performance of the near-infrared sensors, necessitating separate replacements which are not addressed in existing technologies.
Innovation Solution
A mounting structure for near-infrared sensors and sensor covers on vehicles, allowing for separate replacement by using first and second fastening portions and support portions, enabling the sensor cover to be detached and replaced from the outer side and the near-infrared sensor to be detached and replaced from the inner side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the near-infrared sensor and sensor cover are integrated together, then the structure is simplified, but both components must be replaced together when either deteriorates, increasing maintenance complexity and time
Solution Approach 1:
The patent implements separate fastening mechanisms: a first fastening mechanism for attaching the sensor cover to the exterior component, and a second fastening mechanism for attaching the near-infrared sensor to the exterior component. This allows the sensor cover to be replaced without removing the sensor, and the sensor to be replaced without removing the cover, enabling independent maintenance of each component and reducing total replacement time.
Solution Approach 2:
The patent designs the mounting structure with removable and reattachable fastening mechanisms that allow dynamic reconfiguration. The sensor cover and sensor can be independently attached or detached from the exterior component, providing flexibility in maintenance operations and allowing partial replacements without full system disassembly.
2Ease of operation
If separate fastening mechanisms are provided for the sensor cover and near-infrared sensor, then independent replacement is enabled, but the mounting structure becomes more complex with multiple fastening portions and support portions
Solution Approach 1:
The patent divides the fastening system into distinct functional segments: first fastening portions (including first support portions and first fastening portions) for the sensor cover, and second fastening portions (including second support portions and second fastening portions) for the near-infrared sensor. Each segment operates independently, allowing targeted maintenance while keeping the overall structure organized and manageable.

AI summary
A first fastening portion is provided on a surface on the inner side of a sensor cover. A first support portion is provided around an opening of an exterior component. The first fastening portion is fastened to the first support portion, with the first fastening portion being allowed to be unfastened from the first support portion. The exterior component includes a tubular wall portion. The tubular wall portion includes an attaching hole. Part of the near-infrared sensor is arranged inside the tubular wall portion through an attaching hole of the tubular wall portion. The near-infrared sensor includes a second fastening portion. The exterior component includes a second support portion on or outside the tubular wall portion. The second fastening portion is fastened to the second support portion, with the second fastening portion being allowed to be unfastened from the second support portion.
