Solution Overview

Problem

Conventional Mokumegane ring manufacturing methods fail to create pairs of rings that visually convey the design concept of being produced from the same source, lacking a strong reminiscent feature.

Innovation Solution

A ring manufacturing method involving the formation of a circular member into a ring shape, followed by twisting and cutting a binding portion to create two rings with a cohesive design, utilizing multiple metal plates laminated and heated for diffusion bonding, and subsequent processing steps to achieve a unified pattern.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the metal plate is cut into two after twist processing to create two rings, then two rings can be manufactured from one metal plate, but the rings lack a strong reminiscent design concept that they were produced from the same source

Engineering Contradiction:

Improvemanufacturing efficiencyVSAvoiddesign concept realization

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

The metal plate is divided into two separate rings through a specific cutting process that preserves the twisted binding portion, allowing both rings to retain visual evidence of their common origin while being manufactured from a single source material

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The twist processing is performed on the metal plate before cutting it into two rings. This preliminary twisting creates a binding portion that visually connects the two rings, establishing the reminiscent design concept before the separation occurs

Inventive Principle:

Principle #10Preliminary action

2Shape

If multiple metal plates are laminated and joined to create a unified pattern, then the Mokumegane technique can be applied, but the process complexity increases

Engineering Contradiction:

Improveunified patternVSAvoidprocessing steps

Core Design Contradiction:

ShapeVSDevice complexity

Solution Approach 1:

Multiple metal plates with different colors are laminated together and joined through heating to create a unified Mokumegane pattern. This merging of separate materials into a single integrated structure enables the characteristic wood-grain-like patterns while maintaining manageable processing steps

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Form the oval rings 25 from the circular rings 23. Then, twist the oval rings 25, for instance three times, around center of the longitudinal direction, and create the ring portion for male 31 and the binding portion at the both side of the binding portion. After that, obtain the rings for male 2 and the rings for female 3 by cutting the binding portion.
