Solution Overview

Problem

Existing pressing devices for tool holders with little or no conicity are inefficient for accommodating different tool sizes and adjusting pressing pressures, as they are often limited to a single tool size and lack easy pressure adjustment.

Innovation Solution

A pressing device with a modular design featuring separable shells, axially movable pressing plates, and adjustable pressure cylinders, allowing for interchangeable jaw arrangements and varying pressure levels through hydraulic control and piston configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a pressing device is designed for a single tool size, then the pressing pressure can be optimized for that specific size, but the device cannot accommodate different tool sizes

Engineering Contradiction:
Improveaccommodation of different tool sizesVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The pressing device is divided into modular components: interchangeable jaw arrangements that can be swapped for different tool sizes, and separable shells that can be reconfigured. This segmentation allows the device to adapt to various tool sizes without redesigning the entire system, resolving the contradiction between versatility and complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device incorporates universal features such as adjustable pressing plates, interchangeable jaws, and a modular shell structure that can accommodate multiple tool sizes and pressing configurations. This multi-functionality enables a single device to replace multiple specialized devices, achieving adaptability without proportionally increasing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the pressing pressure is fixed, then the device structure can be simplified, but the pressing pressure cannot be adjusted for different requirements

Engineering Contradiction:
Improveadjustment of pressing pressureVSAvoidpressure control mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The pressing device incorporates dynamic pressure adjustment capabilities through adjustable pressing plates and controllable pressure cylinders. The pressing pressure can be varied depending on the tool size and material requirements, transforming a static system into a dynamic one that adapts to different operational conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device allows changing the pressing pressure parameter through adjustable mechanisms including variable piston configurations and controllable hydraulic systems. By enabling parameter adjustment, the device achieves versatility in handling different pressing requirements while maintaining a manageable structure through standardized adjustment mechanisms.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If multiple devices are used for different tool sizes, then each device can be optimized for its specific purpose, but the overall system complexity and space requirements increase

Engineering Contradiction:
Improvecoverage of different tool sizesVSAvoidnumber of devices
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The pressing device is designed as a universal system that can handle multiple tool sizes through interchangeable components and adjustable mechanisms. Instead of requiring separate dedicated devices for each tool size, this single multi-functional device replaces multiple specialized devices, reducing the total quantity of equipment needed.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The device combines multiple pressing capabilities and tool size accommodations into a single integrated system. By merging functions that would otherwise require separate devices into one unified platform with interchangeable components, the solution reduces the number of devices while maintaining comprehensive coverage of different tool sizes.

Inventive Principle:
Principle #5Merging (Combining)
