Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional frame assembly methods are time-consuming and costly, lacking ease of assembly and additional features that enhance the quality of the framed article and the framing experience.
Innovation Solution
A snap-fit framing system comprising a hollow outer frame element with recesses and ribs, and a back plate with locking ribs, allowing for easy assembly and secure attachment, enabling the frame to be easily assembled and displayed on walls or surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional frame assembly methods using wood pieces attached at corners are used, then the frame provides structural strength, but the assembly process becomes time-consuming and costly
Solution Approach 1:
The frame is divided into modular components (outer frame element, back plate, spacer) that can be independently manufactured and then quickly assembled together through snap-fit connections, eliminating the need for time-consuming corner joining of traditional wood frames
Solution Approach 2:
Traditional mechanical joinery methods (screws, nails, adhesives) are replaced with a snap-fit mechanical interlocking system using ribs and recesses that provide both structural strength and rapid assembly without requiring additional fastening materials or tools
2Ease of manufacture
If traditional frame assembly methods are used, then the frame can be constructed, but the assembly process becomes costly
Solution Approach 1:
The locking ribs and recesses are pre-formed as integral features of the molded components during manufacturing, eliminating the need for additional assembly steps or specialized tools, thereby reducing both time and cost
Solution Approach 2:
The frame components are manufactured using injection molding processes that allow for rapid production of complex geometries with integrated locking features, changing the manufacturing parameter from traditional woodworking to plastic molding for cost and time efficiency
3Ease of manufacture
If a simple frame structure is used, then the manufacturing is easier, but additional features that improve quality and display options are lacking
Solution Approach 1:
The back plate is designed with multiple functions: it provides structural support, enables wall hanging through integrated hanging means, and allows tabletop display through an integrated kickstand, all within a single molded component that maintains manufacturing simplicity
Solution Approach 2:
The kickstand is nested within a recess in the back plate, allowing it to be stored when not in use and providing versatile display options without adding external complexity or multiple separate components

AI summary
A frame system according to one embodiment includes a hollow outer frame element that includes a plurality of recesses formed along inner faces of walls of the outer frame element. The outer frame element further includes a plurality of ribs formed along the inner face and an inner landing that protrudes inwardly into a center opening of the outer frame element. The frame system also includes a back plate configured for insertion into the center opening. The back plate includes a plurality of locking ribs for reception within the plurality of recesses to generate a snap-fit attachment of the back plate to the hollow outer frame element.
