Solution Overview

Problem

Existing workpiece support members for thermal processing machines require full replacement when damaged, leading to increased production costs and labor, as well as potential issues with rattling and deformation due to repeated use.

Innovation Solution

A workpiece support member with a base member and removable supporting members made of carbon fiber, where the supporting members are attached via protruding attachment parts and can be easily swapped out when damaged, utilizing the elasticity of carbon fiber to prevent rattling and simplify production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If workpiece support members are made as single integrated members, then structural strength and stability are improved, but replacement cost and labor increase when damage occurs

Engineering Contradiction:
Improvestructural strengthVSAvoidreplacement cost and labor
Core Design Contradiction:
StrengthVSEase of repair

Solution Approach 1:

The workpiece support member is divided into two separate parts: a base member and a supporting member. The supporting member that contacts the workpiece can be detached and replaced independently from the base member, allowing only the damaged portion to be replaced rather than the entire integrated structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The supporting member is designed as a replaceable component that can be discarded when damaged and recovered/reused the base member. This allows selective replacement of only the consumable supporting member while retaining the reusable base member, reducing overall replacement costs.

Inventive Principle:
Principle #34Discarding and recovering

2Reliability

If workpiece support members are replaced frequently due to thermal processing damage, then workpiece quality is maintained, but production cost and downtime increase

Engineering Contradiction:
Improveworkpiece qualityVSAvoidproduction cost and downtime
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

By segmenting the support member into replaceable supporting members and a reusable base member, the system allows quick replacement of only the damaged supporting members during thermal processing, minimizing downtime while maintaining workpiece quality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple supporting members are prepared in advance and can be quickly swapped during processing. This preliminary preparation allows for rapid replacement without extensive setup time, reducing production downtime.

Inventive Principle:
Principle #10Preliminary action

3Stability of the object's composition

If supporting members are made from carbon fiber with elastic properties, then rattling and deformation are prevented, but manufacturing complexity increases

Engineering Contradiction:
Improverattling and deformation preventionVSAvoidmanufacturing complexity
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The supporting member is made from carbon fiber, a composite material that provides both the necessary mechanical strength and elastic properties to prevent rattling and deformation during thermal processing, while allowing for lightweight construction.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The elastic properties of carbon fiber are utilized to change the mechanical behavior of the supporting member, allowing it to flex slightly and absorb vibrations rather than rigidly resisting them, thereby preventing rattling and deformation.

Inventive Principle:
Principle #35Parameter changes

AI summary

A workpiece support member for a thermal processing machine is installed on a workpiece support table to support a workpiece to be thermally processed, and includes a base member and a supporting member. The base member is formed of a plate-like member in a horizontally long shape, and provided with a plurality of protruding supporting member attachment parts at predetermined distance intervals on an upper part thereof. The supporting member is formed of a plate-like member in a horizontally long shape, and is installed in an attachable and removable state with a lower side thereof fitted alternately to a front surface and a rear surface of each of the adjacent supporting member attachment parts of the base member.
