Self-Tensioning Frame for Sheet Media Using V-Groove Mating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing framing systems for sheet media are complex, require multiple pieces, need retaining members on the media, and lack flexibility and self-tensioning capabilities, making them difficult to install and adjust.
Innovation Solution
A frame assembly with a base plate and cover plate of unibody design using lightweight metallic alloys, featuring a 'V' groove for self-tensioning, rivet nut spaces, and small channels for drilling guides, allowing for easy assembly and resizing, with minimal contact points for versatile mounting on varying surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional framing systems with multiple pieces and spline grooves are used, then the sheet media can be held in place, but the configurational complexity increases and installation becomes difficult
Solution Approach 1:
The patent combines multiple framing components into a single integrated frame member with built-in features. The frame member incorporates mounting elements, tensioning mechanisms, and media retention features all in one piece, eliminating the need for separate spline strips, multiple frame pieces, and complex assembly procedures while maintaining reliable sheet media holding capability
Solution Approach 2:
The frame member is designed as a universal component that performs multiple functions simultaneously: it provides structural support, holds the sheet media through built-in grooves, enables tensioning through integrated mechanisms, and facilitates mounting to various surfaces through adaptable mounting elements. This multi-functionality reduces the number of components needed while ensuring reliable media retention
2Ease of operation
If adhesive material is used to mount the framed work to the surface, then the mounting is simple, but the tolerance for installation error is reduced and flexibility is limited
Solution Approach 1:
The mounting elements are designed to be adjustable and adaptable rather than fixed. The frame member can accommodate variations in surface geometry and installation alignment through movable or repositionable mounting features, allowing installers to correct minor errors and adapt to different surface conditions while maintaining simple mounting procedures
Solution Approach 2:
The mounting elements are designed to work with various surface types and geometries, providing universal mounting capability. The frame can be mounted to flat surfaces, curved surfaces, and surfaces with varying tolerances using the same basic mounting mechanism, thereby maintaining both simplicity and flexibility across different installation scenarios
3Reliability
If the frame assembly is mounted in exactly the same dimensions as the sheet media, then the sheet media can be properly supported, but any dimensional mismatch requires remounting the frames
Solution Approach 1:
The frame member is designed with segmented or modular features that allow for easy adjustment of dimensions. The frame can be divided into adjustable sections or include expandable elements that enable fine-tuning of the frame size to match the sheet media dimensions, eliminating the need for complete remounting if slight adjustments are needed
4Ease of manufacture
If multiple pieces are used to form the frame, then the frame can be assembled, but the number of pieces increases and assembly becomes more complex
Solution Approach 1:
The patent integrates multiple frame components into a single monolithic or tightly-integrated frame member. Features that would traditionally require separate pieces—such as mounting brackets, tensioning elements, and media retention structures—are combined into one unified component, reducing assembly complexity while maintaining manufacturing feasibility through optimized design

AI summary
A media frame assembly for displaying a sheet of media against a mounting surface comprising a base plate and a cover plate. The base plate has multiple features so as to minimize contact with the mounting surface, space for rivet nuts, adhesive strip to secure media prior to mating with cover plate, and a channel and groove to mate with legs and protrusion from cover plate. The cover plate has multiple features so as to mate with base plate, simplify installation, and legs and protrusion to mate with channel and groove located in the base plate. The channel and groove located in the base plate operate in conjunction with legs and protrusion in cover plate to provide some tensioning of the media when the cover plate is mated to the base plate.
