Foldable Artwork Substrate with Adhesive-Free Locking Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing artwork substrates face environmental concerns due to the use of non-environmentally friendly gesso or its synthetic equivalents and difficulties in securing a canvas substrate to a wooden frame to form a taught receiving surface for art media, as well as the need for adhesives to maintain the frame configuration.
Innovation Solution
A foldable artwork substrate comprising a laminate of wood pulp and polymeric material, where the polymeric layer provides reinforcement without interfering with the art medium application, and a two-part locking mechanism secures the frame without adhesives, allowing for a planar configuration for transportation and a folded configuration for display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If gesso or synthetic equivalent is used to treat the canvas, then the receiving surface is prepared for art medium application, but environmental concerns arise due to non-environmentally friendly materials
Solution Approach 1:
The patent changes the chemical composition parameters of the receiving surface treatment by replacing traditional gesso (lead carbonate and rabbit skin adhesive) or synthetic equivalents (titanium dioxide and calcium dioxide in polymeric carrier) with an environmentally friendly alternative comprising calcium carbonate and starch adhesive. This parameter change maintains the functional properties of the receiving surface while eliminating harmful environmental factors.
2Stability of the object's composition
If a canvas substrate is stretched across a wooden frame, then a taught receiving surface is formed, but it is relatively difficult to secure the canvas to the frame
Solution Approach 1:
The patent merges the canvas substrate and wooden frame into a single integrated substrate unit. The frame forming element is constructed from the same material layers as the receiving surface (wood pulp and polymeric material), creating a unified structure that eliminates the need for separate canvas stretching and securing operations. The foldable connection integrates both components while maintaining the taught surface property.
3Ease of operation
If the substrate is provided in a folded configuration, then transportation and storage are facilitated, but the frame forming element requires adhesive to maintain configuration
Solution Approach 1:
The patent implements a self-service mechanism where the frame forming element maintains its folded configuration through its own structural properties rather than requiring external adhesive. The foldable connection between the receiving surface and frame is designed to self-maintain through the inherent mechanical properties of the integrated material structure, eliminating the need for adhesive application systems.
4Ease of manufacture
If a single sheet of material is used for both receiving surface and frame, then manufacturing is simplified, but the frame must be secured in configuration requiring adhesive
Solution Approach 1:
The single sheet construction achieves self-service by designing the foldable connection to maintain the frame configuration through its own structural integrity. The integrated material structure (wood pulp and polymeric material layers) provides inherent mechanical stability that allows the frame to hold its shape without adhesive, combining manufacturing simplicity with structural self-sufficiency.
