Introduction of Project selected
The automotive industry has grown tremendously since the days of the Ford model T encountering many innovations. The invention of windshield wiper system is one such innovation that dates back over 100 years. While the activation of the device has witnessed number of improvements and advancements through advancing technology over the last 100 years, the methodology for cleaning the windshield has remained fairly constant since its inception. With the increasing number of automobiles, highways and drivers, came increasing risk and safety, however the inclement weather conditions have remained and will remain to be a constant problem. In this thesis, the design and implementation of high speed air is utilized to create a curtain to repel the rain from the automobile windshield instead of using the traditional wiper blades. The air generated can be through compression system or a blower system that allows the air to move upward and parallel to the windshield. The application can further incorporate a hydrophobic coating covering the windshield to improvise its potential. The use of multiple nozzle connected to a blower creates a continuous curtain or sheet over the windshield, thus repelling the rain under precipitous atmosphere, thereby increasing visibility and eliminating the need for a wiper. On the other hand this innovative idea can also work in tandem with the traditional wiper system, improvising its performance. It can find its application in commercial automobiles, aircraft, as the weather conditions are highly unpredictable where the windshield is subjected to extreme precipitation, and high-speed air can be more beneficial over the traditional wiper
Scope and Objective of the Project selected
• To develop a low cost mechanism using air as a medium for windshield design.
• To analyze the mechanism developed for its performance in comparison with the existing system.
• Analysis of data and presentation.
Abstract
In this creative design process a number of designs were constructed, implemented and tested in order to assess the feasibility of using high speed to create a curtain to repel the rain from the automobile windshield instead of using the traditional wiper blades. The primary two methods tested used a compression system and a blower system that allowed the air to flow upward and parallel to the windshield. Both of the applications showed potential especially when coupled with a hydrophobic coating covering the windshield. The design using the high-speed squirrel cage blowers was implemented on an actual car in which it revealed positive results, which will be further assessed for patenting potential
Plan of work
Phase I: Purchase the required materials
Phase II: A small air compressor has to be connected to a multiple nozzle outlet across the length of the windshield and the nozzles have to be inclined parallel to the windshield.
Phase III: Depending on the results speed of compressed air is to be adjusted for better efficiency
Phase IV: Rain X is applied which seals the pores of the windshield and tests are conducted again and the results are compared with the previous tests.
