Solution Overview

Problem

Existing oil supply guides in textile machines face issues with oil leakage and difficulty in determining if oil is discharged through discharge ports, leading to inefficiencies and increased costs due to the need for flowmeters and visual checks.

Innovation Solution

An oil supply guide design featuring a stepped portion adjacent to the discharge port, which temporarily holds oil and changes appearance when oil is not being discharged, allowing for easy visual verification of oil flow without the need for flowmeters or costly installations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a flowmeter is installed at each discharge port path to determine oil discharge status, then the ability to specify which discharge port is blocked is improved, but the device complexity and cost increase significantly

Engineering Contradiction:
Improvedischarge port identification accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The oil supply guide structure itself serves as the detection mechanism. The stepped portion automatically indicates discharge status through oil accumulation visibility, eliminating the need for external flowmeters or complex detection systems. The system monitors its own state through the visual indicator built into the structure.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The stepped portion acts as an intermediary element between the discharge port and the observer. It accumulates discharged oil in a visible manner, translating the invisible oil flow into a visible indicator that can be easily observed without complex instrumentation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If visual checking of discharge ports is performed, then the cost is reduced, but the ability to determine oil discharge is worsened because running yarn blocks the view of discharge ports

Engineering Contradiction:
Improvecost reductionVSAvoiddischarge port visibility
Core Design Contradiction:
Ease of manufactureVSDifficulty of detecting and measuring

Solution Approach 1:

The stepped portion creates a new viewing dimension or location for oil accumulation. Instead of viewing the discharge port directly (which is blocked by yarn), the indicator is positioned in a different spatial location where oil accumulates in the stepped portion, making it visible from above without interfering with the yarn path.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The stepped portion serves as an intermediary indicator that translates the discharge status into a visible form in a location that is not blocked by the running yarn. It provides an indirect but clear visual signal of oil discharge status.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Quantity of substance

If the amount of oil discharged through each discharge port is set to be small, then the oil application to yarn is optimized, but the ability to determine whether oil is discharged is worsened because it becomes difficult to detect

Engineering Contradiction:
Improveoil discharge amountVSAvoidoil discharge detectability
Core Design Contradiction:
Quantity of substanceVSDifficulty of detecting and measuring

Solution Approach 1:

The stepped portion preliminarily accumulates the discharged oil before it continues to the yarn. This preliminary accumulation in a visible location amplifies the visual indicator effect, allowing even small amounts of oil discharge to be clearly detected through the accumulated oil in the stepped portion.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The stepped portion acts as an intermediary accumulation zone that concentrates and visualizes small amounts of discharged oil. It serves as a magnifying indicator that makes trace amounts of oil visible through accumulation in a confined visible space.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An object of the present invention is to enable easy determination of whether oil is discharged through a discharge port (61a), with low costs. A discharge port (61a) allowing oil to be discharged is formed in an adjacent portion (64) which is adjacent to an opposed portion (63) in a direction orthogonal to a running direction of a yarn (Y). Furthermore, a stepped portion (65) formed of a protrusion is provided immediately below the discharge port (61a) in the adjacent portion (64). Furthermore, an oil guiding surface (67) allowing the oil discharged through the discharge port (61a) to be guided from the adjacent portion (64) to a contact surface (63a) of the opposed portion (63) is provided. The stepped portion (65) is able to temporarily hold a part of the oil which is discharged through the discharge port (61a) and which flows toward the oil guiding surface (67).
