Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional craft punch production methods are resource-intensive, inflexible, and wasteful, requiring multiple molds and assemblies for each shape, limiting their application to single-direction cutting.
Innovation Solution
A craft punch with a replaceable cutting tool system featuring a main body with movable parts, a tubular receiving component for upper and lower cutting molds, and a positioning structure with springs and guide ribs, allowing for easy replacement and multi-directional cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional craft punch uses fixed single-direction cutting molds, then cutting precision is maintained, but flexibility and adaptability are severely limited
Solution Approach 1:
The cutting mold is divided into separable upper and lower portions, with the lower cutting mold being removable and replaceable. This segmentation allows different cutting shapes to be used by simply replacing the lower mold rather than requiring complex multi-directional fixed molds, thereby improving flexibility while maintaining manageable device complexity
Solution Approach 2:
The invention introduces a dynamic, movable lower cutting mold that can be easily removed and replaced through a gap in the lower mold holder. This dynamic design enables the craft punch to adapt to different cutting directions and shapes by swapping molds, significantly enhancing versatility without requiring a completely complex reconfiguration system
2Manufacturing precision
If traditional craft punch produces dedicated molds for each shape, then cutting precision is ensured, but resource consumption and manufacturing cost increase
Solution Approach 1:
The lower mold holder structure with its gap design serves multiple functions: it holds the lower cutting mold, allows for easy removal and replacement of the mold, and provides structural support. This universal design enables a single holder to work with multiple different cutting molds, reducing the need for multiple dedicated holders and thus reducing material waste
Solution Approach 2:
The invention facilitates easy discarding of worn or single-use cutting molds through the removable lower mold design, while the durable lower mold holder can be recovered and reused with different molds. This approach reduces overall material consumption by separating the reusable structural component from the consumable cutting elements
3Stability of the object's composition
If traditional craft punch uses integrated mold holders, then structural stability is maintained, but operational flexibility and ease of maintenance deteriorate
Solution Approach 1:
The mold holder is segmented with a deliberate gap that separates the functional cutting portion from the structural holding portion. This segmentation allows the lower cutting mold to be independently removed and replaced while the holder remains stable and intact, achieving both structural stability and operational flexibility
Solution Approach 2:
The gap in the lower mold holder acts as an intermediary mechanism that facilitates easy mold replacement. This gap serves as a mediator between the stable holder structure and the replaceable cutting mold, allowing smooth insertion and removal of molds without compromising the overall structural stability of the holder
4Manufacturing precision
If traditional craft punch requires complete perpendicular extension of upper mold, then cutting accuracy is achieved, but device complexity and resource usage increase
Solution Approach 1:
The upper cutting mold is designed to be self-aligning through its interaction with the lower cutting mold and holder structure. The perpendicular alignment is achieved through the self-service mechanism of the mold interfaces and positioning features, eliminating the need for complex external alignment systems or overly elaborate upper mold structures

Implementation Method 1
a positioning structure for positioning the insertion of the upper cutting mold, which comprises a positioning ball and a small spring which are sequentially installed in a hollow part of the tubular part
Implementation Method 2
guide ribs for guiding the upper cutting mold holder receiving component to move up and down are installed in the passage on the upper part of the main body

AI summary
A craft punch with a replaceable cutting tool includes a main body having an upper part and a lower part which are spaced up and down. The upper part has a passage, and the lower part has a receiving part to movably receive a lower cutting mold holder. An upper cutting mold holder receiving component could be installed in the passage movably up and down, the upper side of the receiving component bulges to form a tubular part, and one side of the receiving component back to the tubular part is provided with a receiving part which could movably receive an upper cutting mold; a cover plate covers the upper end of the passage and is provided with a through hole allowing the tubular part to pass through an upper bulge, and an upper cover covers the upper side of the cover plate, and is connected with the tubular part.
