Automobile Sunshade Mounting via Positioning Unit and Fixing Strip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mounting automobile sunshades on internal window frames are either time-consuming due to the need for manual alignment and squeezing into positioning ends or prone to misalignment due to visual prediction of adhesive positions, especially when using magnetic elements.
Innovation Solution
A method involving a fixing strip formed by stacking a first release layer, an adhesion layer, and a second release layer, with a torn portion, allows for convenient adjustment and accurate positioning of a positioning unit relative to the sunshade on the window frame, using a double-sided tape and crosslinking agent to ensure secure adhesion without misalignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If magnetic elements are used to adsorb the sunshade to the window frame, then the sunshade can be quickly positioned and removed, but misalignment of magnetic elements occurs due to visual prediction of adhesive positions
Solution Approach 1:
The patent introduces a positioning structure with positioning protrusions and positioning grooves as an intermediary mechanism between the sunshade and window frame. This mechanical positioning system guides the magnetic elements into correct alignment during assembly, eliminating the need for visual prediction and ensuring precise placement while maintaining quick installation.
Solution Approach 2:
The positioning grooves and protrusions are pre-formed on the window frame and sunshade respectively before assembly. This preliminary structuring establishes the correct relative positions of magnetic elements in advance, so that during actual assembly, the components self-align without requiring visual prediction or manual adjustment.
2Reliability
If multiple positioning ends are squeezed into notches one by one, then the sunshade can be securely fastened, but the process becomes time-consuming
Solution Approach 1:
The patent combines multiple positioning functions into a single integrated positioning structure. Instead of separately squeezing multiple positioning ends into notches, the design merges these functions into one snap-fit action where the positioning protrusion engages with the positioning groove, achieving secure fastening in a single operation rather than multiple sequential steps.
Solution Approach 2:
The positioning system is segmented into distinct functional elements: a positioning protrusion on one component and a corresponding positioning groove on the other. This segmentation allows each element to perform its specific function independently, with the protrusion providing mechanical engagement and the groove providing alignment and reception, thereby simplifying the overall assembly process.
