Embossing Apparatus with Movable Stage and Flexible Mat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing embossing apparatuses have limited flexibility in creating arbitrary patterns due to the need for custom dies and large size, which restricts the degree of freedom and efficiency in embossing processes.
Innovation Solution
An embossing apparatus with a movable stage, flexible mat, and controlled tool movement allows for embossing without dies, enabling arbitrary pattern creation and compact design by using a conveyor system and pen tools to form recesses and cut lines on sheet-like media.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If dies are used for embossing, then embossing precision is improved, but adaptability deteriorates because custom dies are needed for each pattern
Solution Approach 1:
The patent uses a projection tool that copies the desired pattern geometry directly, eliminating the need for physical dies. The projection tool can be repositioned and reconfigured to create different patterns, providing both precision and adaptability without manufacturing custom dies for each design
Solution Approach 2:
The patent employs a movable projection tool that can be dynamically repositioned along the sheet using the conveyance mechanism. This dynamic positioning capability allows the same tool to create various patterns at different locations, replacing static dies with a flexible, movable system
2Ease of operation
If a platen roller with supply reel is used, then feeding function is improved, but apparatus size increases
Solution Approach 1:
The patent extracts the feeding function from a large platen roller and supply reel system and implements it through a simpler conveyance path with movable stage. This removes the bulky components while retaining the essential feeding capability, significantly reducing apparatus size
Solution Approach 2:
The patent uses a flexible mat on the movable stage to hold and feed the sheet, replacing the rigid, space-consuming platen roller structure. This flexible approach achieves the same feeding function with minimal space requirements
3Ease of operation
If embossing is performed above the platen roller, then embossing function is achieved, but vertical height increases
Solution Approach 1:
The patent changes the spatial arrangement by moving the embossing operation to the same horizontal plane as the sheet on the movable stage, rather than positioning it vertically above a platen roller. This dimensional repositioning reduces vertical height while maintaining embossing functionality
Solution Approach 2:
The patent merges the embossing tool with the movable stage system, allowing the projection tool to press against the sheet directly on the stage. This integration eliminates the need for separate vertical positioning mechanisms, reducing overall apparatus height

AI summary
An embossing apparatus includes a base, a work table, a mat, a pen carriage and a first tool. The base includes a conveyance path extending in a first direction. The work table is attached to the conveyance path and moves in the first direction. The mat is arranged on the work table. The pen carriage is spaced apart from the base and moves in the second direction parallel to the major surface of the work table and different from the first direction. The first tool is arranged on the pen carriage and moves in the third direction perpendicular to the major surface of the work table. The first tool moves in the third direction and is pressed against a medium adhered on the mat, thereby forms a recess in the medium.
