Solution Overview

Problem

Existing diamond wire cutting machines for quarries face challenges with large dimensions due to non-collapsible tightening columns, requiring extensive space for transport, difficulty in centering the pulleys with stone holes, and inability to handle uneven terrain, leading to inefficiencies in operation and material usage.

Innovation Solution

A compact diamond wire cutting machine with a collapsible tightening column, horizontally and vertically adjustable legs, and a combination of electric and hydraulic motors for enhanced mobility and adaptability, allowing for reduced dimensions during transport, precise alignment, and operation on uneven surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the tightening column is fixed and non-collapsible, then the machine structure is simple and stable, but the transport dimensions are large and space-consuming

Engineering Contradiction:

Improvetransport dimensionsVSAvoidcolumn structure

Core Design Contradiction:

Length of moving objectVSDevice complexity

Solution Approach 1:

The tightening column is divided into multiple telescopic segments that can be extended or retracted relative to each other. This segmentation allows the column to collapse into a compact form for transport while extending to full height for operation, resolving the contradiction between transport dimensions and operational functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The tightening column transitions from a static, fixed structure to a dynamic, adjustable structure. The telescopic mechanism enables the column to change its length dynamically - collapsed for transport and extended for cutting operations - thereby reducing transport dimensions without compromising operational stability.

Inventive Principle:

Principle #15Dynamics

2Measurement precision

If the pulleys are fixed in position, then the machine structure is simple, but the alignment with stone holes is difficult and time-consuming

Engineering Contradiction:

Improvep pulley alignmentVSAvoidposition adjustment mechanism

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The pulley system is made dynamically adjustable through horizontal displacement of the cart along the tightened wire and vertical adjustment of the tightening column. This allows precise alignment with pre-drilled holes in the stone while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The cart incorporating the movable pulleys is designed to perform multiple functions: it holds the pulleys, allows horizontal displacement for alignment, and can be vertically positioned by adjusting the tightening column. This multi-functionality reduces the need for separate alignment mechanisms.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the machine operates on fixed guides, then the cutting path is precise, but the mobility and adaptability to different terrains are reduced

Engineering Contradiction:

Improveterrain adaptabilityVSAvoidcutting path precision

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The machine replaces the traditional guide rail system with a self-propelled wheeled chassis that moves autonomously. The diamond wire itself serves as the guide, maintaining cutting precision while allowing the machine to navigate uneven terrain and be easily repositioned between cutting locations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The machine transitions from a static, guide-dependent system to a dynamic, self-mobile system. The adjustable legs and telescopic column allow the machine to adapt its configuration to uneven ground while maintaining cutting accuracy through the flexible wire system.

Inventive Principle:

Principle #15Dynamics

4Adaptability or versatility

If the machine has fixed legs, then the structure is stable and simple, but the ability to handle uneven terrain and adjust cutting angles is limited

Engineering Contradiction:

Improvecutting angle adjustmentVSAvoidmachine stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The legs are designed with vertical adjustability, allowing each leg to be independently positioned to compensate for uneven terrain. The telescopic tightening column also provides dynamic angle adjustment capability. These dynamic adjustments maintain machine stability while enabling adaptation to various cutting angles and ground conditions.

Inventive Principle:

Principle #15Dynamics
