Solution Overview

Problem

Conventional drilling and bolting rigs require complex fluid power systems and external hoses, which can lead to complications and constraints in movement and operation.

Innovation Solution

A boom system for supporting a drilling and bolting tool that incorporates a fluid passage within the boom structure, allowing for actuation of the tool using pressurized fluid, and includes actuators and flow distributors to facilitate translational and rotational movements without external hoses, utilizing a single pump system for distributed hydraulic control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If external hoses and complex fluid power systems are used to actuate the drilling and bolting tool, then the tool can be powered and controlled, but the system complexity increases and movement constraints are introduced

Engineering Contradiction:
Improvemovement freedomVSAvoidfluid power system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent integrates the fluid passage directly into the boom structure, merging the hydraulic supply system with the mechanical support structure. This eliminates the need for separate external hoses and reduces system complexity while maintaining full actuation capability of the drilling and bolting tool.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The boom structure serves multiple functions: it provides mechanical support for the drilling and bolting tool, acts as a fluid conduit for hydraulic power transmission, and enables positional adjustment. This multi-functionality reduces the need for separate components and simplifies the overall system.

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

2Reliability

If multiple external hoses are connected to the drilling and bolting rig for fluid power actuation, then the tool can be actuated, but wear and maintenance requirements increase

Engineering Contradiction:
Improvereduction of wearVSAvoidnumber of fluid conduits
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The fluid passage is integrated into the boom structure as a built-in conduit rather than using separate external hoses. This single integrated passage replaces multiple separate fluid conduits, reducing wear points and maintenance requirements while maintaining reliable fluid power transmission.

Inventive Principle:
Principle #5Merging (Combining)

3Use of energy by moving object

If a single pump system with distributed hydraulic control is used, then power requirements are reduced, but the fluid distribution system must be precisely controlled

Engineering Contradiction:
Improvepower requirementsVSAvoidfluid distribution control
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The boom structure itself serves as the fluid distribution network, with the integrated passage automatically routing hydraulic fluid to the actuator. This self-service approach eliminates the need for complex external distribution systems while enabling single-pump operation.

Inventive Principle:
Principle #25Self-service
