Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional side window retaining elements are complex to attach, lack positioning flexibility, and result in reduced stability due to two-sided attachment, leading to manufacturing variations and potential production scraps.
Innovation Solution
A side window with a holding element attached on one side, utilizing a thicker high-modulus adhesive layer and a contact section with channels for improved adhesive distribution, allowing for flexible positioning and enhanced stability without increasing vehicle body space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional Y-shaped retaining elements are attached to both sides of the side window, then the stability and stiffness of the arrangement is improved, but the attachment process becomes complex requiring sealing devices and multiple filling openings
Solution Approach 1:
The patent extracts the retaining element attachment from one side of the window, making it single-sided. This eliminates the need for sealing devices and complex multi-opening filling processes while maintaining sufficient stability through optimized contact section design and adhesive application
Solution Approach 2:
The patent introduces a specifically designed adhesive as an intermediary between the retaining element contact section and the window surface. This adhesive layer compensates for the reduced contact area by providing enhanced bonding, allowing single-sided attachment without compromising stability
2Object-generated harmful factors
If the gap between mounting section and window surface is sealed to prevent adhesive leakage, then adhesive containment is improved, but the attachment process becomes more complex and time-consuming
Solution Approach 1:
The patent removes the sealing device entirely from the attachment process. By designing the adhesive application system to control adhesive flow through the filling opening and contact section geometry, adhesive leakage is prevented without requiring additional sealing components or steps
3Device complexity
If single-sided retaining element attachment is used to simplify the attachment process, then the attachment complexity is reduced, but the stability and stiffness of the arrangement deteriorates
Solution Approach 1:
The patent changes the parameters of the adhesive layer (increasing thickness to 1-5mm and using high-modulus adhesive with E-modulus of 150-600 MPa) to compensate for single-sided attachment. This maintains the stability and stiffness of the arrangement while keeping the attachment process simple
4Adaptability or versatility
If adhesive layer thickness is increased to improve positioning flexibility and compensate for manufacturing variations, then positioning flexibility is improved, but the required adhesive quantity and potential leakage increase
Solution Approach 1:
The patent applies adhesive locally through a controlled filling opening and distributes it through channels in the contact section. This ensures the adhesive is placed precisely where needed, maintaining positioning flexibility while preventing excessive adhesive quantity and potential leakage
