Solution Overview

Problem

Conventional cutting devices for ceramic or resin materials require users to rotate screws using a tool to attach and detach processing targets, which is burdensome and inefficient.

Innovation Solution

A processing target holding device with independent first and second holding portions, guide portions, and pressing mechanisms that allow the processing target to be sandwiched and held without the need for a tool, enabling easy attachment and detachment by guiding and pressing the target between the holding portions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If screws are used to connect the first and second holding members, then the processing target can be securely held, but the user must rotate screws using a predetermined tool which increases operational burden and time

Engineering Contradiction:
Improveholding stabilityVSAvoidattachment and detachment operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The holding members are designed to automatically connect and disconnect without requiring external tools. The first holding member with holding groove and the second holding member with protrusion automatically engage when the processing target is placed, and can be easily separated by pulling, eliminating the need for screw rotation tools

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The screw connection mechanism is completely removed from the holding structure. Instead of using screws to connect the first and second holding members, the patent uses a groove-protrusion engagement system that achieves secure holding without any fastening tools

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If screws are used to connect the holding members, then the structure is stable, but the attachment and detachment process becomes time-consuming

Engineering Contradiction:
Improvestructural stabilityVSAvoidattachment and detachment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The holding members automatically engage through their groove-protrusion design when the processing target is positioned between them, eliminating the time-consuming screw fastening process. Detachment is achieved by simple pulling motion without any tool operation

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The holding groove and protrusion are pre-configured in specific positions and orientations so that when the processing target is placed, the components automatically align and engage, achieving rapid attachment without manual adjustment or tool operation

Inventive Principle:
Principle #10Preliminary action

AI summary

A processing target holding device comprising: a first holding portion (71) that holds a first end portion (9a), which is one end in a first direction of the processing target (5), and extends in a second direction orthogonal to the first direction; a second holding portion (72) that holds a second end portion (9b), which is an end on an opposite side of the processing target (5) to the first end portion (9a), and extends in the second direction at a position facing the first holding portion (71); a guide portion (62,63) that is provided in at least any one of the first holding portion (71) and the second holding portion (72) to guide movement of the processing target (5) in the second direction; a first pressing mechanism (64) that is provided in the first holding portion (71) to press the processing target (5) toward the second holding portion (72); and a second pressing mechanism (65) that is provided in the second holding portion (72) so as to face the first pressing mechanism (64) to press the processing target (5) toward the first holding portion (71 ).
