Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle sunshade technologies face issues with adhesive loosening over time, complex installation processes, and increased production costs due to magnetic elements detaching and sliding during prolonged use.
Innovation Solution
A sunshade holding structure featuring a flexible frame with notches, a sunshade cloth, and positioning members with latch grooves and magnetic elements for secure magnetic attachment to the vehicle window frame, allowing quick and easy installation and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adhesive layers are used to attach fastening blocks to the vehicle window frame, then the sunshade can be installed and removed, but the adhesive loosens over time and generates residues
Solution Approach 1:
The patent replaces the adhesive bonding system with a magnetic attraction system. The positioning member includes a magnetic element that magnetically attracts to the ferromagnetic material in the vehicle window frame, eliminating the need for adhesive layers. This substitution resolves the contradiction by providing reliable, residue-free attachment that maintains bonding stability over time while still allowing easy installation and disassembly.
Solution Approach 2:
The patent changes the attachment mechanism from chemical bonding (adhesive) to magnetic attraction. By changing the physical parameter of the attachment force from adhesive strength to magnetic force, the system achieves both ease of operation and long-term reliability without adhesive loosening or residue generation.
2Reliability
If magnetic elements are attached to holes in the casing members, then the window covering can be magnetically attached to the window frame, but the magnets loosen and slide after a period of time
Solution Approach 1:
The positioning member is designed with a specific structure that preliminarily positions the magnetic element in a fixed location. The positioning member itself acts as a carrier that prevents the magnetic element from sliding or detaching, ensuring stable positioning before the magnetic attraction even engages with the window frame.
Solution Approach 2:
The positioning member serves as an intermediary between the magnetic element and the window frame. Instead of attaching magnets directly to the window frame through holes in the casing, the positioning member mediates this connection, providing structural support and positional stability while enabling magnetic attachment.
3Object-affected harmful factors
If the sunshade is attached to the inner side of the window frame, then sunshine blocking is effective, but gaps may allow sunshine projection
Solution Approach 1:
The positioning member is designed with specific structural features (flanges, latch groove) that locally enhance the attachment quality. These features ensure the positioning member aligns precisely with the window frame, eliminating gaps and improving sunshine blocking effectiveness at critical locations.

AI summary
A sunshade holding structure comprises a flexible frame, a sunshade cloth and at least one positioning member. The flexible frame has at least one notch on the circumference thereof. The sunshade cloth covers the flexible frame to form a sunshade. The positioning member has two flanges extended towards the sunshade, a latch groove formed between the flanges to latch on the notch of the flexible frame, and a housing compartment opposite to the latch groove to hold a magnetic element. The positioning member is latched on one side of the notch of the flexible frame and turned to align with the circumference of the flexible frame so that the positioning member can be held securely on the flexible frame. Moreover, the magnetic element of the positioning member also attracts the inner side of a vehicle window frame to form secure positioning. Installation and disassembly also can be done quickly.
