Blind Cover Positioning Structure for Vehicle Sunshade
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sunshade device configurations for vehicles are complex and have a large number of parts, making the installation of blind covers cumbersome and inefficient.
Innovation Solution
A blind cover positioning structure that includes a plate-shaped shielding portion and a supporting portion with a flexible engagement portion, which is inserted into an installation groove in the guide rail, allowing for easy and accurate positioning by deflecting and contracting to fit into an engaged portion, reducing the number of parts required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple clips are provided on guide rails and outer roof panel to support the blind cover, then the blind cover is securely supported, but the installation work becomes complicated and the number of parts increases
Solution Approach 1:
The patent combines multiple support functions into a single integrated supporting portion. The supporting portion includes engagement portions that engage with both the guide rail and outer roof panel simultaneously, eliminating the need for separate clips at each location. This merging of support functions reduces the number of parts while maintaining secure support of the blind cover.
Solution Approach 2:
The supporting portion is designed as a multi-functional component that performs multiple support functions. It provides engagement with both the guide rail and outer roof panel, and also includes positioning functionality through the engagement portions. This universal component replaces multiple specialized clips, simplifying the overall structure while maintaining reliability.

3Ease of operation
If the engagement portion is flexible in groove width direction, then the supporting portion can be easily inserted into the installation groove, but the positioning precision may be reduced
Solution Approach 1:
The engagement portion is designed with flexibility in the groove width direction, allowing it to dynamically adapt during insertion. The flexible engagement portion can deflect to accommodate the insertion process, then maintains engagement after insertion. This dynamic property enables easy insertion while still achieving accurate positioning through the engagement with the engaged portion.
Solution Approach 2:
The engagement portion changes its physical state from a flexible condition during insertion to a engaged condition after insertion. The flexibility parameter allows easy insertion, while the engagement geometry ensures precise positioning. This parameter change enables the component to satisfy both ease of operation and positioning precision requirements.
