Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for cooling shrink chucks are either inefficient with compressed air or require complex designs for liquid coolant collection and drying, lacking a simple and cost-effective solution for rapid cooling across different sizes.
Innovation Solution
A device with a liquid coolant supply system and suction unit that sucks off the coolant from the cooling attachment, allowing for effective and rapid cooling without the need for complex collection systems, and can be used for various shrink fit chuck diameters, with optional integration of an induction device for shrinking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If compressed air is used for cooling the shrink chuck, then the cooling process is simple, but the cooling effect is limited and slow
Solution Approach 1:
The patent uses a two-phase cooling approach: first using compressed air (pneumatic) for initial cooling, then transitioning to liquid coolant (hydraulic) for rapid heat removal. The system switches from gas-based cooling to liquid-based cooling to achieve both simplicity and high cooling efficiency.
Solution Approach 2:
The patent changes the physical state and properties of the coolant from gas (compressed air) to liquid (coolant liquid) to dramatically improve the cooling effect. This parameter change allows the system to achieve rapid cooling while maintaining operational simplicity.
2Productivity
If liquid coolant is sprayed on the shrink chuck with a pot-shaped container for shielding, then rapid cooling is achieved, but the design becomes complex requiring collection containers and drying devices
Solution Approach 1:
The patent extracts the coolant collection function from the cooling attachment itself and relocates it to a separate, movable collection container. This separation allows the cooling attachment to remain simple while still achieving rapid cooling with liquid coolant.
Solution Approach 2:
The patent introduces dynamic, movable components (the collection container that can be moved into position) rather than fixed, complex integrated systems. This dynamic approach reduces the permanent structural complexity while maintaining effective coolant collection and drying capabilities.
3Adaptability or versatility
If a single cooling attachment is designed to accommodate different shrink chuck diameters, then versatility is improved, but the gap between attachment wall and chuck wall increases reducing cooling efficiency
Solution Approach 1:
The patent segments the cooling system into modular components, including interchangeable or adjustable cooling elements that can be positioned at optimal distances from the chuck surface. This segmentation allows maintaining effective cooling gaps while accommodating various chuck diameters.
Solution Approach 2:
The patent creates a universal cooling attachment design that can handle multiple chuck sizes through adjustable or interchangeable components. The system maintains cooling effectiveness across different diameters by allowing flexible configuration of the cooling elements relative to the chuck surface.
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
Enables efficient and rapid cooling of shrink fit chucks, ensuring they are dry post-cooling, and allows for a single cooling attachment to be used across a wide diameter range, with the option to also facilitate shrinking.
Implementation Method 1
air being sucked in at the underside of the cooling attachment by the suction unit via the suction line. The air sucked in entrains the liquid coolant and transports it to a collection container.
Implementation Method 2
The liquid coolant, through which a particularly effective and rapid cooling of the shrink fit chuck can be achieved
Implementation Method 3
a pump with the help of which it generates a carrier gas flow, which is charged with a liquid cooling medium, so that a coolant flow consisting predominantly of the carrier gas in terms of volume is created
