Problem

Conventional seal carving apparatuses require multiple dedicated attachments for different types and sizes of workpieces, leading to complex operation and a risk of incorrect attachment mounting, resulting in improper processing.

Innovation Solution

A seal carving apparatus that uses a single attachment with dot pattern perforations to identify the workpiece type, preventing mismounting through a photosensor-based reading system that ensures accurate positional alignment and consistency with user-inputted information, allowing for versatile handling of various workpiece types and sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple dedicated attachments are prepared for different types and sizes of workpieces, then the seal carving apparatus can handle various workpiece types, but the device complexity and ease of operation deteriorate due to the need to select and mount the correct attachment

Engineering Contradiction:
Improveability to handle various workpiece typesVSAvoidnumber of attachments required
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal attachment design that can accommodate multiple types and sizes of workpieces through a single attachment body. The attachment includes a workpiece holding area with adjustable or adaptable features that allow different workpiece configurations to be secured properly, eliminating the need for multiple dedicated attachments while maintaining versatility across various stamp types and sizes

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple dedicated attachments are prepared for different types and sizes of workpieces, then the seal carving apparatus can handle various workpiece types, but the ease of operation deteriorates due to the risk of incorrect attachment mounting

Engineering Contradiction:
Improveability to handle various workpiece typesVSAvoidsimplicity of attachment selection and mounting
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent incorporates a reading means (such as a sensor or detection device) that automatically identifies the type and size of the mounted workpiece and provides feedback to the control means. This feedback mechanism verifies that the correct workpiece is properly mounted on the attachment, preventing improper processing and simplifying operation by eliminating manual selection errors. The system can detect workpiece characteristics and confirm proper mounting before initiating the carving process

Inventive Principle:
Principle #23Feedback

3Device complexity

If a single attachment is used for various workpiece types, then the device complexity reduces, but the measurement precision and manufacturing precision may deteriorate without proper identification mechanisms

Engineering Contradiction:
Improvenumber of attachments requiredVSAvoidaccuracy of workpiece type identification
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The reading means detects workpiece characteristics (such as dimensions, shape, or identifying features) and provides feedback to the control means, enabling automatic identification and verification of the correct workpiece type. This ensures precise measurement and recognition of workpiece parameters even when using a single universal attachment, preventing errors in processing different workpiece types

Inventive Principle:
Principle #23Feedback

4Ease of operation

If a reading means is added to identify workpiece type, then the ease of operation improves by preventing mismounting, but the device complexity increases

Engineering Contradiction:
Improveprevention of incorrect attachment mountingVSAvoidaddition of reading means and control system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The reading means and control system work together to enable the apparatus to automatically verify and confirm proper workpiece mounting without requiring manual intervention or expertise from the operator. The system self-checks workpiece identification and mounting status, providing automatic error detection and prevention, which simplifies operation despite the added complexity of the detection system

Inventive Principle:
Principle #25Self-service

AI summary

Dot pattern perforations (43) predetermined according to a type (kind and carving size) of a workpiece are formed in a part of a body of an attachment (40, 50, 60, 70, 80) where the workpiece is to be set. A seal carving apparatus (100) detects the dot pattern of the mounted attachment by means of photosensors (18S, 18D) to identify the type of the workpiece. This makes it possible to check consistency between type information on the workpiece input by a customer and type information identified from the dot pattern to prevent mismounting of the attachment or an erroneous carving operation.
