Solution Overview

Problem

Current motorized windshield shade devices are cumbersome to manually place and remove, and there is a lack of effective solutions to prevent interior vehicle damage from sunlight and UV rays, which leads to overheating and potential injury upon re-entry.

Innovation Solution

A motorized windshield shade device with a shade component that can be raised and lowered via a push button or vehicle ignition, utilizing a track and pulley system within the A-pillar, featuring a flexible rod to conform to the windshield shape, and is concealed behind the dashboard when not in use, powered by the vehicle's battery or a separate battery, allowing for automatic operation and manual control via a smart device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a collapsible sunshade is manually placed and removed from behind the windshield, then the device can block sunlight and UV rays, but the operation becomes tiring and burdensome

Engineering Contradiction:

Improvesunlight and UV ray blockingVSAvoidmanual placement and removal

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent replaces the manual mechanical system with an automated motorized system. The motorized shade device uses an electric motor to automatically deploy and retract the shade component, eliminating the need for manual placement and removal while maintaining effective sunlight and UV ray blocking.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The motorized shade device operates autonomously without requiring user intervention for deployment and retraction. The system can be controlled via push buttons or vehicle ignition signals, allowing it to service itself by automatically positioning the shade component to block harmful rays when needed and retracting when not in use.

Inventive Principle:

Principle #25Self-service

2Extent of automation

If the shade component is integrated into the A-pillar with track and pulley system, then the device provides automated operation, but the device complexity increases

Engineering Contradiction:

Improveautomated shade deploymentVSAvoidtrack and pulley system integration

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The patent integrates the motor, track system, and pulley mechanism within the existing A-pillar structure of the vehicle. The shade component nests within the A-pillar housing when retracted, and the motor and mechanical components are compactly arranged within the same space, minimizing additional complexity while achieving automated operation.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The A-pillar structure serves multiple functions: it provides structural support for the vehicle, houses the motorized shade mechanism, and contains the track and pulley systems. This multi-functionality reduces overall device complexity by utilizing existing structural elements rather than adding separate dedicated components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Shape

If the shade component is concealed at the dashboard base when not in use, then the device maintains a clean appearance, but the retrieval space is limited

Engineering Contradiction:

Improveconcealed positioningVSAvoidstorage space at dashboard base

Core Design Contradiction:

ShapeVSVolume of stationary object

Solution Approach 1:

The patent transitions from horizontal storage space at the dashboard base to vertical space utilization within the A-pillar. The shade component is concealed within the vertical A-pillar structure when not in use, effectively using the vertical dimension rather than horizontal dashboard space, thereby maintaining a clean appearance while accommodating the component within available structural volume.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A motorized windshield shade device is disclosed that comprises a shade component that can be raised and lowered via a push button or by turning off or starting the vehicle ignition. The shade component travels between at least one track and pulley system and motor positioned within the A-pillar of a vehicle between the windshield and the pillar trim. When not in use, the shade component is concealed at the base of the dashboard of the vehicle. Further, the top of the shade component comprises a flexible rod, which allows the shade component to conform to the shape of a windshield. The shade component is raised or lowered over a vehicle windshield to keep the vehicle's interior cool and prevent UV damage.
