Clipless Weather Strip Attachment via Integrated Locking Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weather strip attachment methods for automobile grilles require clips, which can cause interference due to small gaps between the grille and body, making reliable attachment difficult.
Innovation Solution
A weather strip design featuring an attachment wall, a sealing wall, and an insertion section with locking portions that can be locked onto the grille's through hole, eliminating the need for clips and allowing easy attachment even in tight spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clips are used to attach the weather strip to the grille, then the weather strip can be securely attached, but the clips cause interference due to small distance between the grille and the body
Solution Approach 1:
The invention extracts and eliminates the clips from the attachment system. Instead of using separate clip components that interfere with the body, the weather strip itself is designed with integrated locking portions that directly engage with the grille's through holes, removing the harmful interference while maintaining secure attachment
Solution Approach 2:
The invention introduces the locking portions as an intermediary mechanism between the weather strip and the grille. These locking portions serve as a mediating structure that enables secure attachment through the through holes without requiring external clips that would interfere with the body
2Reliability
If clips are used to attach the weather strip, then attachment can be achieved, but the attachment process becomes complex and requires additional components
Solution Approach 1:
The invention merges the attachment function directly into the weather strip structure by integrating locking portions into the weather strip body. This consolidation eliminates the need for separate clip components, simplifying the overall attachment structure while maintaining reliable attachment
Solution Approach 2:
The weather strip is designed to be self-attaching through its integrated locking portions that directly engage with the grille's through holes. The structure serves its own attachment function without requiring external clips or additional attachment components, reducing overall system complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy and reliable attachment of the weather strip to the grille without clips, overcoming interference issues and reducing manufacturing costs by using a combination of molding-die-molded and extrusion molded parts.
Implementation Method 1
a sealing wall which is connected to the attachment wall and comes into elastic contact with the hood
