Deformable Substrate Stress Relief for Artwork Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of polystyrene and other deformable substrates in artistic reproductions and publications is hindered by their fragility and tendency to tear or crack during manufacturing and mounting processes, posing environmental concerns and damage risks.
Innovation Solution
The substrate is configured with notched or rounded corners and preformed holes to reduce stress propagation, allowing for secure mounting to frames and binding within publications without causing tears or fractures, using thermoformable plastics that can be bent or deformed without cracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If PVC substrates are used for artwork reproductions, then resistance to tearing is improved, but environmental harm increases when discarded
Solution Approach 1:
The patent changes the material parameter from PVC to polystyrene, transforming the substrate from environmentally harmful to environmentally friendly while maintaining adequate mechanical properties through design modifications
Solution Approach 2:
The patent divides the substrate into distinct functional zones: an image-bearing portion that remains intact and flanges with notched corners that are designed to fail first, protecting the main artwork area from stress propagation
2Object-generated harmful factors
If polystyrene substrates are used for artwork reproductions, then environmental friendliness is improved, but susceptibility to fracturing and tearing increases
Solution Approach 1:
The patent applies preliminary action by pre-notching the corners of the substrate before mounting. These notches create predetermined stress relief points that prevent uncontrolled cracking during the bending and mounting process, allowing the fragile polystyrene to be successfully framed without fracturing
Solution Approach 2:
The patent extracts the vulnerable corner sections from the main image-bearing area by creating notches. This removes the stress concentration points that would otherwise propagate cracks into the artwork portion, effectively isolating the structural weakness to non-critical areas
3Ease of operation
If corners are notched to facilitate mounting, then ease of mounting is improved, but stress propagation increases causing tears and cracks
Solution Approach 1:
The patent applies spheroidality by rounding the corners of the notched flanges. This curvature eliminates sharp stress concentration points that would initiate cracks, allowing the flanges to be bent and mounted without propagating tears into the image-bearing portion of the substrate
