Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices for optical sensors on vehicles are prone to manufacturing defects, leading to the entire device being rejected, despite only a portion being faulty.
Innovation Solution
A modular cleaning device for optical sensors composed of segments with independent cleaning fluid circulation channels and connectors that allow for secure attachment and detachment, enabling replacement of faulty segments without discarding the entire device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a cleaning device for optical sensors is manufactured as a single integrated unit, then the device structure is simple and manufacturing is easier, but the entire device must be rejected if any manufacturing defect occurs
Solution Approach 1:
The cleaning device is divided into multiple independent segments (first segment, second segment, etc.), each with its own cleaning fluid circulation channel and nozzles. This segmentation allows individual segments to be manufactured separately and assembled into a complete device, so that a defect in one segment does not cause rejection of the entire device.
2Reliability
If the cleaning device is designed as modular segments that can be detached and replaced, then the reliability and maintainability improve, but the device complexity increases
Solution Approach 1:
The device is segmented into modular units with standardized connectors that can be detached and reattached. This segmentation enables replacement of faulty segments while maintaining the overall device structure.
Solution Approach 2:
Multiple segments are combined to form a complete cleaning device that surrounds the optical sensor. The segments work together as a unified system while maintaining individual replaceability through complementary connectors.
3Stability of the object's composition
If segments are connected with secure locking mechanisms to prevent movement and rotation, then the structural stability improves, but the manufacturing complexity increases
Solution Approach 1:
The connector system is divided into complementary components (projection and bore, tabs and receiving portions) that work together to provide secure mechanical locking while maintaining manufacturability.
Solution Approach 2:
The connectors are designed to automatically lock segments together through snap-fastening mechanisms, providing self-securing without requiring additional fastening operations or complex assembly procedures.
