Screen Frame Retention Clip with Adjustable Height Spacers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen frame retention devices require multiple sizes to accommodate varying distances between screens and frames, leading to consumer confusion and inefficient hardware store inventory due to the need for numerous differently sized clips.
Innovation Solution
A screen clip with an adjustable height, featuring a projection that can be raised by attaching spacers of varying thicknesses, allowing the clip to securely hold screens of different heights by rotating between retention and release positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple clips of different vertical heights are used to accommodate varying distances between screens and frames, then the fit for different screen distances is improved, but the device complexity and inventory requirements increase
Solution Approach 1:
The clip incorporates a movable projection that can be adjusted to different vertical positions along the clip body. This dynamic adjustment mechanism allows a single clip design to accommodate multiple screen distances, eliminating the need for multiple fixed-size clips. The projection can be positioned at various heights to match different distances between the screen and frame, providing versatility without increasing inventory complexity
Solution Approach 2:
The clip is divided into distinct components including the clip body, movable projection, and spacer elements. This segmentation allows the projection to be independently adjusted relative to the clip body, enabling height customization. The modular structure permits the projection to be repositioned or adjusted to create the appropriate vertical distance for different installation scenarios
2Adaptability or versatility
If a large number of clips of different vertical heights are stocked in hardware stores, then the availability of properly fitted clips is improved, but the shelf space requirements and inventory costs increase
Solution Approach 1:
The clip design achieves multi-functionality through its adjustable projection mechanism. A single universal clip model can serve multiple installation scenarios by adjusting the projection height to match different screen-to-frame distances. This eliminates the need for hardware stores to stock multiple specialized clip sizes, as one versatile clip design can fulfill all height requirements
Solution Approach 2:
The clip allows change in the vertical parameter (projection height) through adjustment mechanisms. By enabling the projection height to be varied within a range, the clip can adapt to different installation distances without requiring different clip models. This parameter variability is achieved through movable components or adjustable spacer systems integrated into the clip design
3Ease of operation
If consumers purchase clips without understanding the height requirements, then the ease of purchase is improved, but the likelihood of purchasing the wrong size increases
Solution Approach 1:
The universal clip design with adjustable projection height eliminates the need for consumers to precisely determine their specific height requirements before purchase. Since one clip model can accommodate a range of distances through adjustment, consumers can confidently purchase this single model without worrying about selecting the correct fixed size, reducing purchase errors

AI summary
A clip for fastening a screen to a frame the has a top and a bottom; an opening extending through the clip. A connector extends through opening to attach the clip to a door or window frame. A projection extends a vertical distance from an end of the clip for holding a screen in place. The clip bottom has a circular recess surrounding the opening. Attachable segments extend from the bottom of the clip having a diameter and a thickness and having an opening for receipt of a connector. The attachable segments bottom has a circular recess surrounding the attachable segments opening. The attachable segment top has a protruding ring that mates with the circular recess on the clip bottom or with a circular recess surrounding an attachable segment opening. The segments raising the vertical distance of the projection so the projection contacts the screen.
