Snap-in Weatherstripping with Segmented Backing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing channelized weatherstripping is difficult to replace due to increased friction and potential debris in the channel, requiring longitudinal insertion which becomes harder over time, especially when channels deform or contain dirt and debris.
Innovation Solution
A snap-in weatherstripping with a plastic backing featuring alternating notched spaces along its sides, allowing for easy side-to-side insertion into a channel without the need for longitudinal insertion, and a weatherstripping material mechanically attached to the backing for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If weatherstripping is inserted longitudinally into a channel, then the weatherstripping can be secured in place, but friction increases and it becomes progressively harder to push longer pieces into the channel
Solution Approach 1:
The backing is divided into multiple segments or sections along its length, with each segment capable of being inserted into the channel independently. This segmentation reduces the overall friction force by breaking down the single long insertion into multiple smaller, easier insertions, directly addressing the technical contradiction between ease of operation and friction force.
2Ease of operation
If weatherstripping is inserted longitudinally into a channel, then the weatherstripping can be secured in place, but channel deformation and debris make replacement difficult
Solution Approach 1:
Instead of inserting the weatherstripping backing into the channel (traditional method), the invention inverts the approach by having the channel insert into the backing. This reversal allows the channel to be accommodated by the backing's receiving structures, making installation and replacement easier even when channels are deformed or contain debris, thus resolving the contradiction between ease of replacement and channel condition reliability.
3Adaptability or versatility
If a flexible backing is used to ease insertion, then the backing can accommodate channel variations, but the backing may lack structural strength
Solution Approach 1:
The backing is constructed from composite materials that combine flexibility and strength properties. This allows the backing to simultaneously accommodate channel variations through its flexible nature while maintaining the structural strength needed for durable installation, directly resolving the technical contradiction between adaptability and strength.
4Strength
If the backing is made strong and rigid, then the backing maintains structural integrity, but it becomes harder to insert into the channel
Solution Approach 1:
The backing incorporates dynamic characteristics, allowing it to flex and deform during the insertion process to ease entry into the channel, then maintain its structural integrity once installed. This dynamic behavior resolves the contradiction between strength and ease of insertion by providing the right properties at the right times in the installation process.

AI summary
A snap in weatherstripping where the backing has a plurality of alternating notched out spaces along each side to facilitate ease of insertion into a channel without the need to slide the weatherstripping longitudinally into the channel. The snap in weatherstripping can be pushed into the channel with a gentle side to side or rolling motion, thus eliminating the difficulties associated with longitudinally sliding a weatherstripping into a channel. The snap in arrangement of the weatherstripping eases replacement, and also accommodates variations in tolerance between the weatherstripping and the channel, making it desirable for replacement of existing degraded weatherstripping.
