Solution Overview

Problem

Existing vehicles lack an effective system for clearing fogging and icing from windshields, windows, and rearview mirrors, especially in severe weather conditions, which impairs visibility and poses safety risks.

Innovation Solution

A visibility enhancement system comprising a wiper blade, wiper blade assembly, motor, and heating conduit that clears ice and snow from windshields, windows, and rearview mirrors by wiping and heating the surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If windshield wipers are used to clear ice and snow, then visibility is improved, but the wipers cannot effectively remove fogging and icing without anti-fogging or deicer liquid

Engineering Contradiction:

Improvevisibility maintenanceVSAvoidfogging and icing

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical wiper system with a thermal heating system. Instead of using mechanical force to scrape ice and snow, the invention uses heated gas or heated liquid discharged through conduits to thermally melt and remove ice and fogging from the windshield surface, thereby addressing the limitation of mechanical wipers against icing and fogging conditions

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention changes the physical state and temperature parameters of the discharged medium. By heating the gas or liquid to elevated temperatures before discharge onto the windshield, the system transforms the thermal energy to melt ice and evaporate fogging, enabling effective clearing of conditions that mechanical wipers cannot handle

Inventive Principle:

Principle #35Parameter changes

2Reliability

If warmed gas or heated liquid is discharged toward the windshield to clear icing and fogging, then visibility is improved, but it requires a lot of time, energy, and fuel

Engineering Contradiction:

Improveicing and fogging clearanceVSAvoidenergy and fuel consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The heating conduits are pre-installed within the windshield structure, allowing immediate discharge of heated medium upon activation. This preliminary positioning enables rapid response to icing and fogging conditions without the need for external equipment setup or prolonged energy application, thereby reducing overall energy and fuel consumption while maintaining effective clearance capability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses pneumatic or hydraulic conduits integrated into the windshield to deliver heated gas or liquid directly to the affected surfaces. This engineered delivery system optimizes the transfer of thermal energy, reducing the total amount of energy and fuel required compared to less efficient heating methods

Inventive Principle:

Principle #29Pneumatics and hydraulics

3Productivity

If existing windshield wiper systems are used, then rain and snow can be cleared, but they lack the ability to clear fogging and icing effectively

Engineering Contradiction:

Improveclearing capabilityVSAvoidweather condition coverage

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The heating conduit system integrated into the windshield provides multi-functional capability. The same thermal heating mechanism effectively clears multiple types of obscurants including ice, snow, and fogging, thereby giving the vehicle a universal clearing system that adapts to various severe weather conditions without requiring separate specialized equipment for each condition type

Inventive Principle:

Principle #6Universality (Multi-functionality)
