Telescopic Profile Strip for Adjustable Building Opening Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective devices for building openings, such as skylights, face challenges in adapting to windows of varying widths, leading to incorrect purchases and the need for suppliers to stock multiple sizes, and users struggle with easy installation of cords for multiple protective elements.
Innovation Solution
A protective device with a telescopic profile strip unit containing a cord drive system, allowing the device to be easily adjusted to different window widths, featuring a cord drive system integrated within a profile strip that can be telescoped, and a pulley-like mechanism for cord guidance, enabling easy installation and operation without external cords.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple protective elements are installed on a building opening, then comprehensive protection (insect and sun protection) is achieved, but installation complexity increases due to difficulty in attaching multiple cords
Solution Approach 1:
The patent combines multiple cord drive systems into a single integrated profile strip unit. The first and second cord drive systems are housed together in one profile strip, allowing both protective elements to be controlled through a unified structure rather than separate cord attachments, thereby simplifying installation while maintaining comprehensive protection functionality
Solution Approach 2:
The profile strip unit serves multiple functions: it houses the cord drive system, provides structural support, and enables control of multiple protective elements. This multi-functional design eliminates the need for separate cord attachment points for each protective element, reducing installation complexity while achieving comprehensive protection
2Manufacturing precision
If fixed-size protective devices are supplied for different window widths, then precise fit is achieved, but inventory complexity increases requiring suppliers to stock multiple sizes
Solution Approach 1:
The profile strip unit incorporates telescopic profile strips that can be dynamically adjusted in length. This dynamic adjustability allows a single protective device design to fit various window widths, eliminating the need for suppliers to stock multiple fixed sizes while maintaining precise fit through on-site adjustment
Solution Approach 2:
The patent enables parameter change in the profile strip length through telescopic adjustment mechanisms. By allowing the length parameter to be modified after manufacturing, a single standardized design can adapt to different window widths, reducing inventory complexity while preserving precise fit capability
3Device complexity
If the cord drive system is located in the first profile strip, then integration is achieved, but adaptability to different window widths becomes difficult without multiple sizes
Solution Approach 1:
The profile strip containing the cord drive system is designed with telescopic capability, allowing its length to be dynamically adjusted. This enables the integrated cord drive system to adapt to different window widths while maintaining its integrated structure, resolving the contradiction between integration and adaptability
Solution Approach 2:
The profile strip is divided into telescopic segments that can be extended or retracted. This segmentation allows the integrated cord drive system to maintain its structural integrity while adapting its overall length to different window widths, achieving both integration and versatility
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 adaptation to windows of different sizes and simplifies installation by integrating the cord drive system within the profile strip, reducing the need for multiple device sizes and ensuring smooth operation without external cord interference.
Implementation Method 1
The cord drive system, which in particular has at least one spring element, is actuated by means of the at least one protective element during the closing and/or opening of the building opening
