Problem
Current blade cutting technologies for leather, hide, and synthetic materials require extensive use of dinking dies, leading to high capital costs and space requirements, and large machinery investments, while seeking a solution that combines the advantages of blade cutting with a compact machine size.
Innovation Solution
A compact cutting table with a single, self-bearing metal block working surface and a fixed arm carrying the cutting unit, eliminating the need for dinking dies by using electronic pattern projection and a modular design for extended use without substantial structural modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If dinking dies are used for cutting materials, then cutting precision is improved, but capital costs and space requirements increase
Solution Approach 1:
The patent replaces physical dinking dies with digital pattern projections. The cutting patterns are stored in the operating system and projected onto the material surface, allowing virtual copying of designs without physical die fabrication. This eliminates the need to manufacture and store numerous physical dies for different cutting patterns.
Solution Approach 2:
The patent substitutes the mechanical dinking die system with an electronic control system that projects patterns and guides a cutting blade. The mechanical interaction between physical dies and material is replaced by electronic pattern mapping and blade positioning controlled by software.
2Manufacturing precision
If dinking dies are used for cutting materials, then cutting precision is improved, but storage space requirements increase
Solution Approach 1:
The patent replaces physical dinking dies with digital pattern projections. The cutting patterns are stored in the operating system and projected onto the material surface, allowing virtual copying of designs without physical die fabrication. This eliminates the need to manufacture and store numerous physical dies for different cutting patterns.
3Adaptability or versatility
If large cutting tables are used for blade cutting, then adaptability is improved, but machine size and capital investment increase
Solution Approach 1:
The patent creates a compact cutting table with universal adaptability through software-based pattern storage and projection. The machine can handle multiple cutting patterns and material types without requiring physical reconfiguration or expansion, as the operating system stores and projects various designs onto the compact work surface.
Solution Approach 2:
The patent transitions from physical expansion (larger tables) to digital expansion (software patterns). Instead of increasing machine dimensions to handle more patterns, the solution projects two-dimensional patterns onto the material surface, allowing unlimited pattern variety within a compact physical footprint.
4Adaptability or versatility
If large cutting tables are used for blade cutting, then adaptability is improved, but capital investment increases
Solution Approach 1:
The patent creates a compact cutting table with universal adaptability through software-based pattern storage and projection. The machine can handle multiple cutting patterns and material types without requiring physical reconfiguration or expansion, as the operating system stores and projects various designs onto the compact work surface.
