Vehicle Sunshade Holding Structure with Extended Bonding Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sunshade holding structures that bond to vehicle window frames via a single plane result in unstable bonding, leading to loosening and dropping when the sunshade is removed improperly, especially on smaller window frame areas.
Innovation Solution
A holding structure with a seat and bonding member that includes two non-parallel bonding surfaces and an extended portion to bond to the window frame's bend portion, enhancing stability by attaching to both sides of the frame or inserting into gaps, and can be used in conjunction with conventional holding blocks for improved usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-plane bonding structure is used to attach the sunshade to the vehicle window frame, then the device complexity is reduced, but the bonding stability deteriorates causing the sunshade to loosen and drop when improperly removed
Solution Approach 1:
The patent transitions from a single-plane bonding structure to a multi-dimensional bonding structure by adding an extended portion that bonds to the bend portion of the window frame. This creates additional bonding surfaces in different spatial dimensions, transforming the bonding from a 2D plane to a 3D multi-surface configuration, thereby enhancing bonding stability without significantly increasing device complexity
Solution Approach 2:
The bonding structure is segmented into multiple functional portions: a seat portion for bonding to the flat surface of the window frame and an extended portion for bonding to the bend portion of the window frame. This segmentation allows each portion to independently contribute to bonding stability, ensuring the sunshade remains securely attached even during improper removal attempts
2Adaptability or versatility
If the bonding area of the double-sided adhesive is reduced to fit smaller window frame areas, then the adaptability to different window sizes is improved, but the bonding force decreases leading to easier loosening
Solution Approach 1:
The extended portion adds a new dimension to the bonding area by utilizing the bend portion of the window frame. This creates an additional bonding surface that is spatially separated from the main seat portion, effectively increasing the total bonding area and strength without requiring a larger footprint on the flat window frame surface, thus maintaining adaptability to various window sizes
Solution Approach 2:
The bonding structure employs asymmetric geometry with the extended portion projecting perpendicular to the seat portion. This asymmetric design allows the bonding structure to adapt to the asymmetric geometry of window frames (including bend portions) while maximizing bonding force through optimized distribution of bonding areas across different surfaces

AI summary
A holding structure and a vehicle sunshade used thereof includes a seat and a bonding member. The seat includes a body, a clamp portion connected to the body and an extended portion connected to the body and extended in a direction remote from the clamp portion. The body has a first connection plane faced the extended portion. The extended portion has a second connection plane faced the body. The bonding member is bonded to the first connection plane and the second connection plane, and includes a first bonding surface corresponding to the first connection plane and a second bonding surface corresponding to the second connection plane. The invention can hold the vehicle sunshade on a vehicle window frame and provide firmer bonding of the vehicle sunshade to the vehicle window frame through the two bonding surfaces.
