Solution Overview

Problem

Existing cooling apparatuses for shrink chucks lack sufficient cooling power, leading to inefficient cooling times.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If a conventional cooling apparatus with simple cooling fluid flow is used, then the device complexity is low, but the cooling power is insufficient leading to long cooling times

Engineering Contradiction:

Improvecooling powerVSAvoiddevice complexity

Core Design Contradiction:

PowerVSDevice complexity

Solution Approach 1:

The cooling attachment is positioned over the shrink chuck before cooling begins, with inlet openings already arranged to direct cooling fluid onto specific surfaces. The discharge device is pre-configured with upwardly directed openings to create upward flow paths. This preliminary arrangement ensures that when cooling starts, the fluid immediately follows optimized paths that maximize cooling efficiency from the beginning, rather than requiring complex real-time adjustments during the cooling process.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The cooling apparatus is divided into distinct functional components: inlet openings for fluid introduction, a discharge device with upwardly directed openings for controlled discharge, and a cooling attachment with specific geometric features. This segmentation allows each component to be optimized independently for its specific function while maintaining overall system simplicity. The modular design achieves enhanced cooling power without proportionally increasing overall device complexity.

Inventive Principle:

Principle #1Segmentation

2Productivity

If the cooling attachment is completely placed on the shrink chuck, then the cooling fluid flow control is improved, but additional cooling fluid cannot be introduced via gaps reducing cooling efficiency

Engineering Contradiction:

Improvecooling efficiencyVSAvoidfluid distribution control

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The cooling attachment features inlet openings and discharge openings positioned at specific locations to create localized cooling zones. The upwardly directed discharge openings concentrate cooling fluid flow in specific upward paths, creating areas of enhanced cooling where needed most. This local quality approach allows effective cooling with controlled fluid distribution rather than requiring complete coverage, maintaining productivity without excessive complexity.

Inventive Principle:

Principle #3Local quality

3Power

If downwardly directed cooling fluid flow is used, then the cooling fluid can be introduced into the interior, but the cooling fluid flows away downward reducing cooling effectiveness

Engineering Contradiction:

Improvecooling effectivenessVSAvoidcooling fluid loss

Core Design Contradiction:

PowerVSLoss of energy

Solution Approach 1:

Instead of directing cooling fluid downward as in conventional designs, the discharge device is configured with upwardly directed openings that invert the flow direction. This causes cooling fluid to rise upward through the shrink chuck, improving cooling effectiveness by maintaining contact with heated surfaces longer and preventing the fluid from flowing away downward. The inversion of flow direction recovers what would otherwise be lost cooling fluid, enhancing power while reducing energy loss.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

An apparatus cools and/or dries a shrink chuck and a method cools and/or dries a tool holder. The apparatus has a cooling attachment which can be fitted over the shrink chuck with the lower end thereof. In the region of the lower end of the cooling attachment guiding elements are arranged such that a first cooling fluid flow can be guided into an interior, which can receive the shrink chuck, of the cooling attachment while producing a turbulent flow which can be brought about by the guiding elements. In the method, the tool holder is dried and/or cooled by a first cooling fluid flow from a first cooling fluid. The first cooling fluid flow flows in the form of a turbulent flow axially in the direction of a tool receiving opening of the tool holder along the tool holder.
