Screwless Side Guide for Rollable Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional side guides for rollable screens are weakened by fixing elements, leading to potential detachment under high wind loads and require labor-intensive mounting and removal processes, which can cause damage and are aesthetically unpleasing due to protruding screws.
Innovation Solution
A screwless side guide system featuring a frame profile with a hinge point and a coupling element that allows rotation and translation, enabling secure attachment and detachment without screws, improving stability and aesthetics by distributing loads evenly and allowing for tool-free installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If fixing elements such as screws and nails are used to attach side guide components, then the components can be securely fastened together, but the fixing elements form the weakest points and may detach under high wind loads
Solution Approach 1:
The patent removes fixing elements (screws, nails, clips) from the side guide structure entirely. The cover profile, hinge element, and coupling element are attached to the frame profile through integration or interference fits rather than separate fastening components, eliminating the weakest points that were prone to detachment under wind load
Solution Approach 2:
The patent merges the cover profile, hinge element, and coupling element into an integrated assembly that attaches to the frame profile as a unit. This consolidation creates a more robust structure where loads are distributed across multiple integrated components rather than concentrated at discrete fixing element locations
2Strength
If fixing elements are used to attach side guide components, then the components can be securely fastened, but mounting and removal become labor-intensive requiring secondary tools and careful handling
Solution Approach 1:
By removing fixing elements such as screws and nails, the patent eliminates the need for secondary tools like screwdrivers during mounting and removal operations. The side guide components can be installed and dismantled through simple insertion and extraction movements
Solution Approach 2:
The patent incorporates a hinge element that enables rotational movement for mounting the cover profile to the frame profile. This dynamic mechanism allows for tool-free attachment by simply rotating the cover profile into place, and facilitates easy removal by reversing the rotation
3Strength
If fixing elements are used to attach side guide components, then the components can be securely fastened, but protruding fixing elements are aesthetically unpleasing and require additional screening casings
Solution Approach 1:
The patent removes all protruding fixing elements from the side guide structure. The integrated attachment method allows components to be mounted flush against the frame profile, creating smooth surfaces on both the inside and outside of the dwelling without visible screws, nails, or clips
Solution Approach 2:
The patent nests the cover profile, hinge element, and coupling element within or against the frame profile structure. This nesting approach allows the components to be attached while maintaining a streamlined appearance, eliminating the need for additional screening casings to cover protruding fasteners
