Snap-Fit Canvas Frame Assembly to Reduce Tool Dependency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of canvas prints into frames is challenging and requires special tools, necessitating a simpler and quicker frame construction and assembly technique.
Innovation Solution
A frame assembly system featuring a frame base with slits and locking openings, and a rear panel with locking tabs, allowing for a snap-fit connection to securely hold a canvas substrate between the frame base and rear panel, facilitated by an adapter fixture with linkages and pins for easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional frame assembly methods are used for canvas prints, then the canvas can be securely mounted, but the assembly process requires special tools and is time-consuming
Solution Approach 1:
The frame is divided into multiple components: a frame base with side walls, a rear panel with locking tabs, and corner pieces. This segmentation allows each component to be independently manufactured and assembled through simple snap-fit operations without requiring special tools, thereby improving ease of operation while maintaining secure mounting
Solution Approach 2:
The locking tabs on the rear panel automatically engage with the frame base through elastic deformation of the material. The system is designed so that the canvas weight and assembly pressure itself activate the locking mechanism, eliminating the need for external tools or complex assembly procedures, thus reducing assembly time while ensuring secure mounting
2Reliability
If traditional frame assembly methods are used for canvas prints, then the canvas can be securely mounted, but the process requires special tools and complex procedures
Solution Approach 1:
The locking tabs are designed to automatically engage with the frame base through elastic deformation when the rear panel is inserted. The canvas weight and assembly pressure activate the locking mechanism without requiring external tools or complex procedures, thereby ensuring reliable mounting while keeping the assembly process simple
Solution Approach 2:
The locking tabs act as intermediaries between the rear panel and frame base, providing a simple snap-fit connection that ensures reliable mounting. The elastic material of the locking tabs mediates the connection, allowing automatic engagement while maintaining structural integrity without complex assembly procedures

AI summary
A method for assembling a canvas print includes the steps of:preparing a canvas substrate that includes a printed side;placing the canvas substrate with the printed side facing down;disposing a base frame over the canvas substrate;folding edges of the canvas substrate over sides of the base frame;inserting a rear panel into the base frame; andpressing the rear panel downward until a snap-fit connection is realized between the rear panel and the base frame with the folded edges of the canvas substrate being captured between the rear panel and the base frame and being taught across a forward face of the base frame.
