Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shading devices face challenges in providing stable and easy-to-assemble spring support systems for guide profile strips, leading to potential tension peaks and complex assembly processes.
Innovation Solution
A shading device with a spring profile strip that is inserted into a channel-like chamber of the holding profile strip, featuring spring tabs and support arms forming a C-shaped cross-sectional area, allowing for resilient support and easy installation, while diverting forces from the cloth to the spring profile strip and then to the holding profile strip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate spring clips are used to support the guide profile strip, then the guide profile strip can be resiliently supported, but the production and assembly becomes very time-consuming and complex
Solution Approach 1:
The patent combines multiple separate spring clips into a single integrated spring profile strip that runs continuously along the guide profile strip. This unified structure provides resilient support at multiple points simultaneously while eliminating the need for separate assembly operations for each spring clip, thus reducing assembly time and complexity while maintaining the reliable resilient support function.
Solution Approach 2:
The spring profile strip serves multiple functions simultaneously: it provides resilient support at numerous points along the guide profile strip, absorbs external loads, and eliminates the need for separate mounting hardware. This multi-functional design replaces what would traditionally require multiple specialized components with a single versatile element.
2Device complexity
If the guide profile strip is supported only at a few points via spring clips, then the assembly is simpler, but stress peaks occur at the spring clips leading to potential failure
Solution Approach 1:
The spring profile strip is designed with multiple segmentation points along its length, where it contacts the guide profile strip at numerous discrete locations. This segmentation distributes the mechanical loads across multiple contact points rather than concentrating them at single points, thereby reducing stress peaks and improving overall strength while maintaining assembly simplicity through the continuous nature of the spring profile.
Solution Approach 2:
The spring profile strip provides localized resilient support at multiple specific points along the guide profile strip. Each contact point between the spring profile and guide profile distributes stress locally, preventing stress concentration at any single point while collectively providing comprehensive support throughout the entire length of the guide profile strip.
3Force
If a separate spring is used to preload the guide profile strip, then the spring action is provided, but the design requires a large number of components and is difficult to assemble
Solution Approach 1:
The spring action function is merged directly into the spring profile strip itself, eliminating the need for a separate spring component. The spring profile strip is designed as a self-contained element that generates the necessary preload force through its own elastic deformation, thereby reducing the total component count while maintaining the required spring action for preloading the guide profile strip.
Solution Approach 2:
The spring profile strip is designed to be self-sufficient, generating its own spring action and preload force without requiring external spring components. The elastic elements within the spring profile strip itself provide the necessary mechanical advantage and force generation, allowing the system to be self-service in terms of providing the spring action function.
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
The solution provides stable and secure support to the guide profile strip, absorbing external loads without excessive tension and simplifying the assembly process, ensuring the guide profile strip remains securely positioned and functional.
Implementation Method 1
The spring profile strip (19) is inserted into the chamber (17) and is resiliently supported by a spring device (18). The spring tabs (22) together with a base section (19a) form a C-shaped cross-sectional area of the spring profile strip (19).

AI summary
A shading device has a cloth which can be stretched out and which, at its end facing in the stretching-out direction, is connected to a drop bar and, at at least one side edge, is in engagement with a guide profile strip. The guide profile strip is arranged in a channel-like chamber of a holding profile strip and is supported on the holding profile strip in a sprung manner by means of a spring device, wherein the spring device has a spring profile strip. There is provision here that the guide profile strip is inserted into a receiving space, which is delimited by spring tabs, of the spring profile strip and is mounted in the spring profile strip in a floating manner, and that the spring profile strip is mounted in the channel-like chamber of the holding profile strip in a floating manner and is supported on an inner wall of the chamber by way of at least one support arm.
