Linear Wiper Assembly to Reduce Sensor Obstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wiper systems for motor vehicles have bulk issues due to the presence of wiper arms and motors, which obstruct detection modules on glazed surfaces, particularly in vehicles with increased numbers of detection modules.
Innovation Solution
A simplified wiper system with an embedded motorized member that drives a linear movement of the blade rubber along the glazed surface, reducing bulk by integrating the motor within the main body and using guide means such as notched belts or gutters for smooth displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional wiper system with wiper arm and motor is used, then the glazed surface can be cleaned, but the bulk of the system increases and obstructs detection modules
Solution Approach 1:
The motor is extracted from the conventional wiper arm assembly and repositioned to the periphery of the detection module, eliminating the need for a bulky central motor housing and reducing overall system volume while maintaining cleaning functionality
Solution Approach 2:
The wiper blade motion is changed from rotational movement around a central axis to linear reciprocating motion along the glazed surface, achieved through a lead screw mechanism that converts rotational motor output into linear blade displacement, thereby reducing lateral bulk
2Ease of operation
If the motor is arranged in the vicinity of the glazed surface, then the wiper blade can be driven, but the lateral bulk over the perimeter increases
Solution Approach 1:
The motor is repositioned from a central location near the glazed surface to the periphery of the detection module, and the drive mechanism uses a lead screw to convert rotational motion into linear motion along the length of the blade, thereby minimizing lateral bulk while maintaining effective blade actuation
Solution Approach 2:
The wiper system is segmented into distinct functional components: the motor is separated and placed at the periphery, the lead screw mechanism is positioned along the blade assembly, and the blade itself is independently mounted, allowing each component to be optimized for its specific function without compromising overall compactness
