Solution Overview

Problem

Existing methods for splitting rock or concrete are hazardous, labor-intensive, and generate significant noise and vibration, with limitations in speed, reliability, and flexibility, particularly due to the need for manual handling of heavy splitting cylinders and precise positioning.

Innovation Solution

A device with a carriage and working head that allows for simultaneous drilling and splitting, using a single unit with a drilling device and a splitting device that can be precisely positioned and operated without manual intervention, enabling larger cleavage planes and flexible angle selection, and incorporating a centering element or GPS for precise alignment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual handling of heavy splitting cylinders is used, then the splitting operation can be performed, but worker safety deteriorates and labor intensity increases

Engineering Contradiction:
Improvemanual handling requirementVSAvoidworker safety
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent combines the drilling device and splitting device into a single integrated unit mounted on a common carriage. The working head can rotate to position either the drilling device or splitting device for operation, eliminating the need for manual handling of separate heavy cylinders while maintaining splitting functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The working head is designed as a multi-functional component that can perform both drilling and splitting operations. By rotating the working head about a second axis, the same structural unit can alternate between positioning the drilling device and the splitting device, making the equipment universal and eliminating manual intervention.

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

2Productivity

If separate drilling and splitting operations are performed, then each operation can be optimized, but productivity deteriorates due to multiple positioning requirements

Engineering Contradiction:
Improveoperation speedVSAvoidnumber of devices
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges two separate operations (drilling and splitting) into a single integrated device. The carriage with the rotatable working head can perform both functions without requiring repositioning or更换 equipment, thereby increasing productivity while maintaining functional optimization through dedicated drilling and splitting components.

Inventive Principle:
Principle #5Merging (Combining)

3Measurement precision

If workers are positioned in the immediate vicinity of the splitting surface, then precise operation can be achieved, but safety deteriorates due to exposure to splintering and sliding materials

Engineering Contradiction:
Improvepositioning accuracyVSAvoidworker exposure to hazards
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The integrated device performs both drilling and splitting operations autonomously without requiring workers to be in the danger zone. The carriage can be positioned and operated remotely, and the device itself handles the precise positioning and execution of both operations, eliminating worker exposure to splintering and sliding material hazards.

Inventive Principle:
Principle #25Self-service

4Force

If heavy splitting cylinders are used for larger operations, then splitting capacity is improved, but ease of operation deteriorates due to increased weight and handling difficulty

Engineering Contradiction:
Improvesplitting forceVSAvoidhandling ease
Core Design Contradiction:
ForceVSEase of operation

Solution Approach 1:

The patent integrates the splitting device with the drilling device on a common carriage system. This allows larger capacity splitting cylinders to be mounted and operated without manual handling, as the entire assembly can be positioned and controlled as a single unit, maintaining high splitting force while improving operational ease through integration.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The device (1) has a drilling device (4) attached at a working head (24). A splitting device (5) i.e. hydraulically driven splitting cylinder (51), is attached to the working head, and generates gap force that acts at right angle to a bore axis and parallel to an axis (26) in a drilled hole in a working position. The working head is rotated at another axis (27) in relation to a carriage (2) such that either the drilling device or the splitting device is alternately brought into the working position by rotating the head at the latter axis and moving the head along the former axis. The drilling device is a drill machine, a percussion drill or a core drill. An independent claim is also included for a method for splitting a fixed material.
