Rigid Jigsaw Puzzle Manufacturing with Cut-Then-Print Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional jigsaw puzzle manufacturing methods involve printing images on paper or paper-derived materials, which are absorbent and soft, making puzzles prone to damage from liquids and physical contact, and require additional steps like cleaning and removing protective layers.
Innovation Solution
A process for making jigsaw puzzles from wood or other rigid materials without paper or coating, where puzzle pieces are cut before printing, using a laser cutting machine and a specialized supporting surface to prevent damage from cutting energy, and then printed on both sides for enhanced image quality and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If paper or paper-derived material layer is used for printing images, then the puzzle can be manufactured using traditional methods, but the puzzle becomes susceptible to damage from liquids and physical contact due to absorbent and soft properties
Solution Approach 1:
The patent removes the paper or paper-derived material layer from the puzzle construction, eliminating the source of absorbency and softness that cause vulnerability to liquid and physical damage. The puzzle is made directly from rigid material such as wood, plastic, or metal sheets without any paper coating or backing layer.
Solution Approach 2:
The patent uses composite or layered rigid materials (such as wood veneer, plastic laminates, or metal sheets) that combine durability with printability. These materials provide both the structural integrity needed for durability and the surface properties needed for image application.
2Loss of information
If images are printed on puzzle pieces before cutting, then the image can be applied to the material, but the cutting process damages the image and requires additional cleaning steps
Solution Approach 1:
The patent performs the cutting operation before the printing operation. The rigid material sheets are first cut into puzzle pieces using laser cutting or other precision cutting methods, then the images are printed on the cut pieces. This sequence prevents cutting tools from damaging the image and eliminates the need for cleaning residue from printed surfaces.
Solution Approach 2:
The patent inverts the traditional manufacturing sequence by cutting before printing rather than printing before cutting. This reversal of the process order solves the problem of image damage during cutting while maintaining manufacturing efficiency.
3Strength
If acrylic sheets with protective paper layers are used, then the sheets can be bonded and cut, but additional steps are required to remove the protective layers
Solution Approach 1:
The patent eliminates the protective paper layers entirely by using rigid materials that do not require such protection. The materials used (wood, plastic, metal) are inherently durable and do not need removable protective coatings, thereby removing the additional removal step from the manufacturing process.
Solution Approach 2:
The rigid materials used in the patent are self-sufficient and do not require external protective layers. The materials themselves provide the necessary durability and structural integrity without needing additional protective treatments or coatings that would require removal.

Function Achieved in This Case
The process results in a more durable and coherent puzzle image with no gaps or cutting residue, allowing for easier replacement of lost pieces and improved image quality, while eliminating the need for cleaning and reducing the risk of image damage during cutting.
Implementation Method 1
using a laser cutting machine
Implementation Method 2
cutting the puzzle pieces from the sheet using the laser cutting machine

AI summary
A process for making a puzzle includes the step of cutting puzzle pieces from a sheet of material and subsequently printing an image on the cut pieces. The resulting puzzle is far more durable than a conventional jigsaw puzzle and because of the process used to make it also benefits from the ability to replace individual pieces if lost. The puzzle is packaged intact in a packaging sleeve assembly designed to durably and aesthetically package the puzzle.
