Universal Sealing Device with Movable Profile and Rod Passage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sealing devices for doors and windows require a large number of variants to accommodate different door widths and the presence or absence of espagnolette rods, leading to increased manufacturing and logistical complexities.
Innovation Solution
A closing assembly for driving bolts is introduced, which can be mounted on the sealing device to accommodate various espagnolette rod backsets, allowing the same sealing device to be used for both doors with and without locking rods, and adaptable to individual casement widths by shortening profiles and adding a passage for the espagnolette rod.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate sealing devices are manufactured for different door widths and espagnolette rod configurations, then the sealing device can be precisely adapted to specific installation requirements, but the variety of variants increases significantly, leading to increased manufacturing complexity and logistical efforts
Solution Approach 1:
The guide profile is designed with a universal structure that can accommodate both doors with and without espagnolette rods. A vertical passage opening is integrated into the guide profile, allowing the espagnolette rod to pass through when present, while not interfering with the sealing function when absent. This enables a single sealing device design to serve multiple door configurations.
Solution Approach 2:
The sealing device is divided into modular components: the guide profile (attached to the door), the support profile (movable within the guide), and the sealing profile (attached to the support). This segmentation allows the same guide profile to be used across different door widths, with only the overall length of the assembled device varying, rather than requiring completely different designs for each door size.
2Device complexity
If the sealing device is designed as a single universal type, then manufacturing and logistics are simplified, but the ability to accommodate specific espagnolette rod backsets and door widths is reduced
Solution Approach 1:
The guide profile incorporates a vertical passage opening that serves multiple functions: it allows the espagnolette rod to pass through for doors with locking mechanisms, provides structural support, and defines the mounting position. This single design element enables the sealing device to work with various espagnolette rod backsets without requiring different guide profile designs.
Solution Approach 2:
While the design of the guide profile and support profile remains constant, the overall length of the sealing device can be adjusted by varying the length of the support profile or the distance between mounting points. This parameter change allows adaptation to different door widths using the same fundamental design.
3Reliability
If the sealing device requires precise alignment with the espagnolette rod axis, then proper functioning of the locking mechanism is ensured, but the manufacturing precision requirements increase
Solution Approach 1:
The support profile is designed to be movable relative to the guide profile within the vertical passage opening. This dynamic capability allows the support profile (and attached sealing profile) to self-align with the espagnolette rod axis during door closing, rather than requiring precise pre-alignment during manufacturing. The movement freedom accommodates variations in espagnolette rod positioning.
Solution Approach 2:
The sealing device performs its own alignment function through the movable support profile that can shift position within the guide profile's passage opening. The device self-adjusts to match the espagnolette rod position without requiring external alignment procedures or high-precision manufacturing tolerances.
