Solution Overview

Problem

The difficulty in visually confirming the insertion of coil inserts into tap holes in workpieces, due to their similar color, leads to reduced work efficiency as users must screw in a screw to verify insertion, which is time-consuming and inefficient.

Innovation Solution

An insert insertion tool equipped with a coating member that holds ink and applies it to the insert, allowing it to stand out visually upon insertion, eliminating the need for screwing in a screw to confirm insertion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If no coating is applied to the insert, then the insert maintains its original appearance, but it becomes difficult to visually recognize whether the insert has been inserted into the tap hole

Engineering Contradiction:
Improvesimplicity of insertVSAvoidvisual recognition of insert insertion
Core Design Contradiction:
Ease of manufactureVSDifficulty of detecting and measuring

Solution Approach 1:

The patent applies a coating member with ink to the insert, changing its color from silver (stainless steel) to a contrasting color that stands out against the workpiece surface. This allows visual recognition of insert insertion without modifying the insert's structural simplicity.

Inventive Principle:
Principle #32Color changes

2Reliability

If a screw is screwed in to confirm insert insertion, then verification is achieved, but work efficiency is reduced due to time-consuming confirmation for each tap hole

Engineering Contradiction:
Improveverification of insert insertionVSAvoidwork efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

By coating the insert with contrasting ink, the patent enables immediate visual verification of insert insertion. Users can see whether an insert is present in each tap hole by observing color contrast, eliminating the need to screw in test screws for verification.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The coating member with ink acts as an intermediary that provides visual information about insert insertion status. Instead of using mechanical verification (screwing in test screws), the ink coating serves as a visual mediator that communicates insertion status.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If an ink holding member is added to the coating member, then ink is properly applied to the insert, but device complexity increases

Engineering Contradiction:
Improvequality of ink applicationVSAvoidstructure of coating member
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent uses a porous ink holding member that absorbs and holds ink. The porous structure naturally retains ink and allows it to be transferred to the insert surface through contact, providing reliable ink application without complex delivery mechanisms.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The ink holding member is designed to automatically transfer ink to the insert through simple contact. The porous material self-regulates ink transfer based on contact pressure and duration, eliminating the need for pumps, valves, or controlled delivery systems.

Inventive Principle:
Principle #25Self-service

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The tool significantly improves work efficiency by enabling visual confirmation of insert placement without the need for additional verification steps, reducing time and cost by using colored ink that contrasts with the workpiece, thus enhancing the recognition of inserted inserts.

Implementation Method 1

the coating member (50) uses the first ink holding member (51) and the second ink holding member (52) to apply ink to an upper surface, which is an exposed surface, of the insert (B1)

AI summary

An insert insertion tool 10 according to an embodiment includes a mandrel 20 on which an insert is mounted, and a coating member 50 configured to apply ink to a rear end on an opposite side of a tip end that first enters a tap hole, of the insert. Accordingly, the insert inserted into the tap hole stands out on a surface of a workpiece, a user is capable of visually recognizing whether or not the insert has been inserted into the tap hole, and thus, the confirmation work becomes easy and it is possible to improve the work efficiency.
