Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If dedicated large machines are used to manufacture custom shoe lasts, then manufacturing precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent divides the shoe last manufacturing process into multiple plate-like parts that can be cut from a single plate-like member using a simple cutting machine. These segmented parts are then assembled to form the complete shoe last, eliminating the need for complex dedicated large machines while maintaining manufacturing precision.
Solution Approach 2:
The patent uses a cutting pattern that is generated based on shoe last data to create accurate copies of the required shoe last components. This copying approach through pattern-based cutting achieves the necessary precision without requiring complex specialized machinery.
2Ease of manufacture
If multiple plate-like parts are assembled to form a shoe last, then ease of manufacture is improved, but assembly time increases
Solution Approach 1:
The patent performs preliminary actions by pre-calculating and optimizing the arrangement of multiple plate-like parts on a single plate-like member before cutting. The cutting pattern is generated in advance with optimal positioning that considers assembly efficiency, so that when the parts are cut and assembled, the process is faster and more efficient.
Solution Approach 2:
The patent combines multiple plate-like parts into a single plate-like member for cutting, allowing all necessary components to be processed together in one operation. This merging approach maintains ease of manufacture while reducing the number of separate cutting operations and subsequent assembly steps.
3Quantity of substance
If plate-like parts are cut from a plate-like member, then material availability is improved, but material waste increases
Solution Approach 1:
The patent performs preliminary arrangement optimization before cutting, where the cutting pattern generation unit calculates the optimal positions and orientations of multiple plate-like parts on the plate-like member. This advance planning ensures maximum material utilization and minimizes waste while ensuring all required parts are available.
Solution Approach 2:
The patent changes the arrangement parameters (positions, orientations, and configurations) of plate-like parts on the plate-like member to optimize material utilization. By adjusting these parameters through computational optimization, the system achieves better material efficiency while maintaining part availability.

AI summary
A cutting support apparatus includes an input unit that receives shoe last data, a storage in which a shape and a type of a plurality of plate-like parts are stored, a processor that generates a cutting pattern for cutting the plurality of plate-like parts from a plate-like member having a predetermined size based on the shoe last data and the shape of the plurality of plate-like parts, and an output unit that outputs the cutting pattern. The processor divides an area of the plate-like parts to be arranged in the plate-like member into a plurality of areas in accordance with the type of the plate-like parts that form the shoe last, determines positions of the plurality of plate-like parts to be arranged in each of the areas based on an arrangement condition, and generates the cutting pattern.
