Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sunshades for vehicle windshields are cumbersome, inefficient, and often fail to provide complete sunlight blocking, leading to interior overheating and potential harm from UV radiation.
Innovation Solution
An automated sunshade system with a motor-driven belt and track system integrated into the vehicle's pillars, controlled via a touchscreen, keyfob, or push button, which extends and retracts a sun-blocking material across the windshield for effective shading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If manual sunshades are used in windshields, then sunlight blocking is provided, but the system is cumbersome and fails to cover the entire window surface
Solution Approach 1:
The patent replaces manual mechanical sunshade systems with an automated motor-driven system. The controller automatically activates the sunshade based on detected sunlight intensity, eliminating the need for manual operation. The motor-driven reel mechanism automatically deploys and retracts the sunshade material across the windshield, providing full surface coverage without user intervention.
Solution Approach 2:
The sunshade system operates autonomously by detecting environmental conditions (sunlight intensity) and automatically adjusting its state. The controller monitors UV sensors and activates the motor when sunlight exceeds threshold levels, allowing the system to serve itself without requiring user awareness or action.
2Object-affected harmful factors
If conventional sunshades are used, then partial sunlight blocking is achieved, but the entire window surface is not covered
Solution Approach 1:
The sunshade system transitions from static conventional shades to a dynamic automated system. The motor-driven mechanism enables the sunshade material to move across the entire windshield surface, expanding from partial coverage to full surface coverage. The system can dynamically adjust its position and coverage area based on operational requirements.
Solution Approach 2:
The sunshade system is divided into functional segments: the sunshade material itself, the motor-driven reel mechanism, the guide assembly with rails, and the controller system. This segmentation allows each component to be optimized independently, with the guide assembly ensuring complete windshield coverage while the motor mechanism provides automated deployment.
3Ease of operation
If automated motor-driven systems are implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The controller serves multiple functions: it monitors UV sensor data, determines when sunshade activation is needed, controls the motor-driven reel mechanism, and manages the overall system operation. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing system complexity while maintaining automated operation.
Solution Approach 2:
The guide assembly with rails acts as an intermediary mechanism between the motor-driven reel and the sunshade material. It provides a structured pathway that guides the sunshade's movement across the windshield, simplifying the mechanical interface and reducing the complexity of direct motor-to-material coupling.
