Solution Overview

Problem

Conventional coolant supply devices require regular maintenance to clean the coolant tank, which involves stopping the machine tool and removing the supply pump and wires, leading to decreased availability due to the inability to completely prevent deposition of chips and sludge within the tank.

Innovation Solution

A coolant supply device with a slidable mounting member and detachable lid body that allows for cleaning of the coolant tank without removing the supply pump or wires, enabling the tank to be cleaned through a non-covered upper opening, thus reducing maintenance time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the supply pump and wires are removed to clean the coolant tank, then the tank can be completely cleaned, but the maintenance time increases and availability decreases

Engineering Contradiction:
Improvecleaning completenessVSAvoidmaintenance time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The mounting member is divided into a pump mounting portion and a wire mounting portion that can be independently removed. This segmentation allows the pump to remain installed while only the wire mounting portion is removed for cleaning access, enabling complete tank cleaning without removing the pump itself.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting member is designed with movable and removable components rather than fixed rigid connections. The wire mounting portion can be selectively removed to provide cleaning access, while the pump mounting portion remains fixed to maintain pump installation. This dynamic design enables flexible maintenance access without complete disassembly.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the supply pump is removed to access the coolant tank, then cleaning can be performed, but the complexity of the maintenance operation increases

Engineering Contradiction:
Improvecleaning accessibilityVSAvoidmaintenance operation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The mounting member is segmented into distinct functional portions: a pump mounting portion that remains fixed and a wire mounting portion that can be independently removed. This segmentation simplifies maintenance operations by allowing direct access to the coolant tank through removal of only the wire mounting portion, without requiring pump removal or complex disassembly procedures.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If the mounting member is made fixed to simplify structure, then device complexity is reduced, but cleaning access to the coolant tank becomes difficult

Engineering Contradiction:
Improvemounting member structureVSAvoidtank cleaning access
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The mounting member is segmented into a fixed pump mounting portion and a removable wire mounting portion. This segmentation maintains structural simplicity for pump installation while enabling easy cleaning access by removing only the wire mounting portion, without requiring complex movable mechanisms or complete disassembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting member transitions from a completely fixed structure to a partially dynamic structure where the wire mounting portion can be selectively removed. This provides cleaning access while maintaining the fixed pump mounting portion, achieving a balance between structural simplicity and operational flexibility.

Inventive Principle:
Principle #15Dynamics
