Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automobile sun-shading devices are complex in structure, large in volume, inconvenient to install and use, and provide a poor sun-shading effect, leading to high fuel consumption due to increased interior temperatures in summer.
Innovation Solution
An automobile sun-shading device featuring a mounting seat, a sun-shading cloth, and a bracket system with foldable connecting rods and a rotary shaft, allowing for automatic unfolding and folding, which includes a motor-driven rotary shaft and a locking mechanism for easy installation and effective shading, with the brackets designed to match the vehicle's profile for improved shading efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If existing automobile sun-shading devices are used, then sun-shading function is provided, but the structure is complex and volume is large
Solution Approach 1:
The sun-shading device is divided into multiple independent brackets (first bracket, second bracket, third bracket) that can be separately assembled and positioned. Each bracket is a discrete component that can be independently adjusted, allowing the system to achieve complex shading configurations without requiring a single monolithic complex structure.
Solution Approach 2:
The brackets are designed with nested capability where the second bracket can be positioned within or alongside the first bracket, and the third bracket extends from the second bracket. This nesting arrangement allows multiple shading surfaces to be compactly stored when not in use, reducing volume while maintaining the ability to deploy extended shading structures when needed.
2Object-affected harmful factors
If existing automobile sun-shading devices are used, then sun-shading function is provided, but installation and everyday use are inconvenient
Solution Approach 1:
The brackets are designed with movable and adjustable connections that allow easy assembly and disassembly. The connecting structures enable the brackets to be dynamically positioned and secured without requiring complex tools or procedures, making installation and everyday operation convenient for the user.
3Object-affected harmful factors
If existing automobile sun-shading devices are used, then sun-shading function is provided, but the sun-shading effect is poor and the automobile cannot be completely shaded
Solution Approach 1:
The device employs multiple brackets arranged in different spatial dimensions and orientations. The first bracket provides primary shading, the second bracket extends shading coverage to adjacent areas, and the third bracket adds additional dimensional coverage. This multi-dimensional arrangement ensures comprehensive shading coverage that adapts to various sunlight angles and vehicle profiles.
