Solution Overview

Problem

Existing milling machines are not suitable for mining all types of rock and are limited in their application, particularly on construction sites for cutting reinforced concrete, as they require prior drilling and are not adaptable for different rock types or depths.

Innovation Solution

A milling machine equipped with a diamond cable as both a drive cable and milling unit, featuring telescopic arms for adjustable spatial extension, and a combined drilling and milling unit on a carrier device, allowing flexible operation and adaptation to various rock types and depths.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If prior drilling is performed in rock before mining, then the known milling machines can operate, but the process becomes limited to specific rock types and requires additional preparatory steps

Engineering Contradiction:
Improveadaptability to different rock typesVSAvoidprocess complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The diamond cable serves dual functions as both the drive cable for power transmission and the milling unit for cutting rock. This eliminates the need for separate drilling and milling operations, allowing the system to handle various rock types directly without preparatory drilling, thereby improving adaptability while reducing process complexity

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

Solution Approach 2:

The invention combines the drive cable and milling unit into a single integrated diamond cable system. By merging these previously separate functions into one component, the system achieves versatility across different rock types without requiring additional preparatory steps or increasing overall process complexity

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If the milling machine has fixed spatial extension, then the structure is simpler, but it cannot be adjusted to different borehole depths or application requirements

Engineering Contradiction:
Improveadjustability to different borehole depthsVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The milling machine incorporates telescopic arms that can be extended or retracted during operation, transforming the structure from static to dynamic. This allows the spatial extension to be adjusted to different borehole depths and application requirements while maintaining reasonable structural complexity through the use of standardized telescopic mechanisms

Inventive Principle:
Principle #15Dynamics

3Length of moving object

If the milling machine is transported in compact form, then transport is easier, but it cannot reach deep boreholes or cover large areas

Engineering Contradiction:
Improvespatial extensionVSAvoidtransportability
Core Design Contradiction:
Length of moving objectVSEase of operation

Solution Approach 1:

The telescopic arms can be retracted to a compact configuration for transport, making the milling machine easy to move to different locations. During operation, the arms are extended to achieve the required spatial extension for deep boreholes or large areas, thus resolving the contradiction between transportability and operational reach

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The telescopic arms are designed to nest within each other when retracted, similar to nested dolls. This nesting configuration minimizes the spatial footprint during transport while allowing full extension during operation, thereby achieving both easy transport and sufficient working reach

Inventive Principle:
Principle #7Nested doll (Nesting)

4Adaptability or versatility

If the diamond cable is used as both drive cable and milling unit, then all types of rock can be mined and reinforced concrete crushed, but the cable must maintain tension while allowing spatial adjustment

Engineering Contradiction:
Improveapplicability to all rock types and materialsVSAvoidcable tension control complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The diamond cable performs both drive and milling functions universally across different materials including all rock types and reinforced concrete. The cable tension control system is designed to maintain appropriate tension regardless of the material being processed or the spatial configuration of the telescopic arms, achieving versatility without proportionally increasing control complexity

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