Solution Overview

Problem

Users are limited in setting hole attributes in three-dimensional CAD data, particularly for hole elements, which affects quotation results and requires user consent from the manufacturer for color contrast information, limiting freedom in setting associated information.

Innovation Solution

A quotation system that acquires shape data from a user's terminal, detects surface information of hole elements, sets hole attributes based on association information, and creates quotation information automatically, allowing users to freely set hole attributes without manufacturer consent.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the user designates hole attributes in shape data, then the quotation result accuracy is improved, but the user freedom and ease of operation deteriorate due to requiring manufacturer consent for color contrast information

Engineering Contradiction:

Improvequotation result accuracyVSAvoiduser freedom

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The system allows users to independently set hole attributes by freely designating color contrast information in shape data without requiring manufacturer consent. The attribute setting section automatically sets hole attributes based on user-designated colors, enabling users to self-configure the system according to their needs

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system changes the parameter of color contrast information from being controlled by manufacturer consent to being freely adjustable by users. By allowing free designation of colors and patterns in shape data, the system enables users to modify hole attributes without external approval, improving ease of operation while maintaining quotation accuracy

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If the user manually sets hole attributes, then the quotation accuracy is improved, but the time required for quotations increases

Engineering Contradiction:

Improvequotation accuracyVSAvoidquotation time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary action by automatically setting hole attributes based on color contrast information designated by users in the shape data. The attribute setting section automatically assigns hole types (tap holes, drill holes, etc.) based on the colors and patterns specified by users, eliminating the need for manual hole-by-hole configuration and significantly reducing quotation preparation time while maintaining accuracy

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system replaces the manual mechanical process of setting hole attributes with an automated computer-based process. The attribute setting section uses algorithms to automatically interpret color contrast information and assign appropriate hole attributes, substituting manual operations with automated processing that is both faster and more consistent

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of manufacture

If the three-dimensional CAM device shares color contrast information, then the manufacturing process is improved, but the user freedom to set hole attributes deteriorates due to requiring manufacturer consent

Engineering Contradiction:

Improvemanufacturing processVSAvoiduser freedom

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The system segments the control of color contrast information from the manufacturer's CAM device to the user's CAD software. By separating the functions, users can freely set colors and patterns in their CAD software without needing consent from the manufacturer's CAM system, while the quotation system still receives and processes this information for accurate hole attribute setting

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system achieves universality by making color contrast information serve multiple purposes: it is used by users for design flexibility in CAD software, and simultaneously used by the quotation system for automatic hole attribute setting. This multi-functional use of color information eliminates the need for manufacturer consent while maintaining both manufacturing capability and user freedom

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A quotation system 100, that receives shape data D1 of an article from a client terminal 40 of a user and provides quotation information of the article, has: a data acquisition section 22A that acquires the shape data of the article including a hole element; a detection section 22B that detects surface information of the hole element among pieces of information assigned to the shape data; an attribute setting section 22C that sets a hole attribute corresponding to the detected surface information to the hole element with reference to association information D2 in which surface information able to be assigned to the shape data and the hole attribute indicating an attribute of the hole element are associated for each user; and a quotation section 22D that creates the quotation information based on the set hole attribute and the shape data.
