Door Sealing Profile With Extended Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door sealing profiles, particularly for metal doors, often fail to achieve a complete seal due to design constraints that prevent the guide profile from covering the entire door length, leading to inadequate sealing at the ends.
Innovation Solution
A sealing profile comprising a guide profile and a support profile, where the support profile protrudes beyond the guide profile at both ends, allowing the seal to extend over the entire door length, with the option for automatic raising and lowering, and made from materials like elastomers, plastic, steel, or aluminum, ensuring effective sealing even where the guide profile cannot be fully arranged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the guide profile is designed according to conventional configurations, then the structure is simple and easy to manufacture, but the seal cannot extend over the entire door length, resulting in inadequate sealing at the ends
Solution Approach 1:
The sealing profile is divided into two distinct components: a guide profile and a support profile. The guide profile attaches to the door and provides structural support, while the support profile extends beyond the guide profile to carry the seal element. This segmentation allows the seal to reach the door ends without requiring the entire guide profile to extend that far, thus improving sealing performance while maintaining manufacturing simplicity.
Solution Approach 2:
The support profile extends in the longitudinal dimension beyond the guide profile's length. This dimensional extension allows the seal element mounted on the support profile to reach areas that the guide profile cannot cover, specifically the end areas of the door, thereby achieving complete end-to-end sealing without increasing the guide profile's complexity.
2Reliability
If the guide profile is extended to cover the entire door length, then complete sealing can be achieved, but the device becomes more complex and difficult to manufacture
Solution Approach 1:
Instead of extending the guide profile to cover the entire door length, the system segments the sealing function between the guide profile (which remains a manageable length for easy manufacture) and the support profile (which extends to provide complete sealing coverage). This segmentation maintains ease of manufacture for the guide profile while achieving full sealing coverage through the extended support profile.
Solution Approach 2:
The support profile acts as an intermediary element that bridges the gap between the guide profile's limited reach and the door's full length requirement. The support profile is partially positioned within the guide profile and extends beyond it, serving as a mediator that carries the seal element to the door ends without requiring the guide profile itself to be excessively long or complex.
3Reliability
If the seal is positioned only within the guide profile area, then the guide profile structure is sufficient, but the end areas of the door remain inadequately sealed
Solution Approach 1:
The support profile extends in the longitudinal dimension beyond the guide profile's end. This extension allows the seal element mounted on the support profile to reach the door's end areas that would otherwise remain uncovered. The seal element can protrude beyond the end of the support profile at least at one end, ensuring complete end sealing without requiring excessive overall length.
Solution Approach 2:
The support profile is pre-configured to extend beyond the guide profile and is designed to be partially positioned within the guide profile during assembly. This preliminary configuration ensures that when the sealing profile is installed, the seal element is already positioned to cover the critical end areas of the door, achieving end sealing without requiring additional adjustment or complex installation procedures.
