Front Pillar Guide Pipe Layout for Sensor Hose Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles equipped with autonomous driving systems, the mounting of flexible component parts like sensor cleaning hoses within the pillar trim poses a challenge as it requires an increase in the pillar cross-section, which is disadvantageous for the driver's view and complicates maintenance.
Innovation Solution
A front pillar structure with a side outer reinforce assembly, guide pipe, and mounting bracket system that allows the flexible component part to be inserted and removed without expanding the pillar cross-section, featuring a guide pipe with open ends and a foam pad layer to reduce noise and improve NVH performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the pillar cross-section is increased to accommodate the sensor cleaning hose, then the mounting space for flexible components is improved, but the driver's view is worsened
Solution Approach 1:
The sensor cleaning hose is nested within the guide pipe, which is installed inside the existing pillar trim. This allows the flexible component to be accommodated without increasing the pillar cross-section, thereby maintaining the driver's view while providing sufficient mounting space for the hose
Solution Approach 2:
The guide pipe acts as an intermediary structure that facilitates the installation of the sensor cleaning hose within the constrained pillar space. The guide pipe provides a dedicated pathway that guides the hose through the pillar trim, enabling mounting without expanding the pillar cross-section
2Adaptability or versatility
If the sensor cleaning hose is mounted inside the pillar trim with other components, then the integration is improved, but the maintenance complexity is worsened
Solution Approach 1:
The mounting system is segmented into distinct components: the guide pipe for hose installation, the mounting bracket for secure attachment, and the pillar trim for integration. This segmentation allows the sensor cleaning hose to be independently installed and removed through the guide pipe without disrupting other pillar components, facilitating easier maintenance while maintaining integration
Solution Approach 2:
The guide pipe provides a dedicated extraction pathway that allows the sensor cleaning hose to be removed from the pillar trim for maintenance without disassembling the entire pillar assembly. The hose can be extracted through the guide pipe's open ends, enabling easy replacement while maintaining integrated mounting
