Modular Roof Sensor Mounting for Easier Vehicle Sensor Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle sensor attaching structures that integrate all sensors as a non-removable unit complicate maintenance when sensor failures occur, as individual sensors cannot be easily replaced or upgraded.
Innovation Solution
A vehicle sensor attaching structure featuring a common sensor unit fixed to the roof with detachable option sensor units that can be attached on multiple sides, allowing for easy maintenance and sensor exchange, while maintaining structural rigidity and lightweight design through a common and option frame body configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all sensors are integrated as a non-removable unit on the roof, then the sensor system achieves structural integrity and simplified installation, but maintenance becomes difficult when sensor failure occurs
Solution Approach 1:
The sensor system is divided into a common sensor unit (fixed to the roof) and detachable option sensor units. This segmentation allows the fixed common unit to maintain structural integrity while the detachable option units can be easily removed and replaced for maintenance, resolving the contradiction between system integrity and ease of repair.
2Device complexity
If sensors are made as a non-removable integrated unit, then the overall structure is simplified, but individual sensor replacement and upgrading becomes complex
Solution Approach 1:
The option sensor units are designed with detachable attachment mechanisms that allow them to be dynamically attached and detached from the common sensor unit. This dynamic design enables simple overall structure while providing flexibility for individual sensor replacement and upgrading without requiring complex disassembly procedures.
3Ease of repair
If option sensor units are attached to the right and left of the common sensor unit, then maintenance accessibility is improved, but vehicle width requirements increase
Solution Approach 1:
The third option sensor unit is attached to the upper side of the common sensor unit and offset to project toward the right or left, utilizing the vertical dimension rather than only horizontal expansion. This dimensional change allows maintenance accessibility while accommodating vehicles with limited width.
