Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for assembling canvas prints into frames are cumbersome and require special tools, making the process difficult and time-consuming.
Innovation Solution
An automated system that includes a frame feeding station, an assembly station with a movable presser head and side guide fingers, and a canvas feed station, which works together to efficiently assemble framed articles by snapping the frame parts together and capturing the canvas between them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional manual assembly methods are used for canvas prints, then the process can be completed with simple tools, but the assembly process becomes time-consuming and requires special tools
Solution Approach 1:
The frame is divided into multiple separate members (front frame, rear frame, side rails) that can be independently manufactured and then quickly assembled together. This segmentation allows for pre-preparation of components and rapid assembly without requiring complex tools or lengthy processes.
Solution Approach 2:
The frame members are pre-configured with attachment features (slots, tabs, grooves) during manufacturing. The canvas is pre-stretched to the correct tension. These preliminary preparations eliminate the need for on-site adjustments or special tools during assembly, reducing both time and complexity.
2Stability of the object's composition
If canvas prints are assembled using conventional frame and mat arrangements, then the structural integrity is maintained, but the assembly process becomes complex and difficult
Solution Approach 1:
The frame members are designed to merge into a unified structure through interlocking features. The front frame, rear frame, and side rails combine to form a stable enclosure that holds the canvas securely, eliminating the need for separate mats and complex bracing structures.
Solution Approach 2:
The frame members incorporate self-aligning and self-securing features such as tapered tabs that fit into corresponding slots, and clips that automatically engage with the side rails. This self-service mechanism ensures structural integrity while simplifying the assembly process to require no specialized tools or expertise.
3Adaptability or versatility
If manual assembly techniques are used, then flexibility in handling different canvas sizes is maintained, but the productivity and output rate are limited
Solution Approach 1:
The frame members are designed with universal attachment features and standardized dimensions that can accommodate multiple canvas sizes. The slot and tab system, along with adjustable side rails, allows the same frame design to be used for various canvas dimensions, enabling rapid assembly across different product specifications.
4Manufacturing precision
If special tools are used for assembling canvas prints, then the assembly precision can be improved, but the ease of operation and accessibility are reduced
Solution Approach 1:
The frame members incorporate self-aligning and self-securing features such as tapered tabs that fit into corresponding slots, and clips that automatically engage with the side rails. This self-service mechanism ensures structural integrity while simplifying the assembly process to require no specialized tools or expertise.

AI summary
An automated system for assembling a framed article including a plurality of canvases and a plurality of assembled frames to be combined with the plurality of canvases to form the framed articles. Each assembled frame is formed of a rear panel and a frame member that are detachably attached to one another with one canvas being stretched across a front face of the frame member. The automated system includes an assembly station including a movable presser head that is configured to detach and lift the rear panel from the frame member and a plurality of movable side guide fingers that are configured to fold side edges of the canvas over sides of the frame member to permit the presser head to press the rear panel down over the folded side edges of the canvas into engagement with the frame member with the canvas being captured between the frame member and the rear panel.
