Hydraulic Brushing System for Windshield Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional windshield wiper systems lack a brush mechanism due to the challenge of integrating rotational motion without increasing weight, as adding a motor makes the accessory heavy and converting linear motion to torque is insufficient for supporting another mechanism.
Innovation Solution
A brushing system incorporating a brush with a hydraulic motor that uses pressurized water to rotate the brush and administer water for cleaning, where the hydraulic motor is powered by a water pump and water tank, allowing the brush to be lightweight and effective.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a motor is added to provide rotational movement to the brush, then the brush can rotate effectively, but the accessory becomes heavy
Solution Approach 1:
The patent applies hydraulic principles by using pressurized water flowing through a hydraulic motor to generate rotational motion of the brush. The hydraulic motor converts the kinetic energy of pressurized water into mechanical rotation, eliminating the need for a traditional electric motor and reducing the weight of the windshield wiper accessory while maintaining effective brush rotation.
2Speed
If linear motion mechanism is used to convert motion to torque, then rotational motion is achieved, but the mechanism becomes too sensitive and insufficient to support another mechanism
Solution Approach 1:
The patent replaces the complex linear motion to torque conversion mechanism with a hydraulic motor that directly converts pressurized water flow into rotational motion. This hydraulic approach simplifies the mechanism by eliminating sensitive linear-to-rotational conversion components, making the system more robust and capable of supporting the brush mechanism without excessive complexity.
3Productivity
If a brush is integrated into the windshield wiper, then cleaning efficacy is improved, but the accessory becomes heavy
Solution Approach 1:
The patent integrates a lightweight hydraulic motor powered by pressurized water into the windshield wiper system to drive the brush. This hydraulic integration enables effective brush rotation for improved cleaning efficacy while maintaining lightweight construction, as the hydraulic motor is significantly lighter than traditional electric motors.
