Solution Overview

Problem

Coring machines struggle to maintain a perpendicular core bit orientation on angled or uneven surfaces, leading to issues like uneven core sides and bit sticking during reinstatement.

Innovation Solution

A mobile coring apparatus with a pivotable mast and angular adjustment mechanism that allows the core bit to remain perpendicular to the horizon, featuring a mast that can pivot between forward, rearward, and intermediate positions, secured by a locking mechanism and pivot wheel assembly, enabling operation on angled surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the coring machine operates on an angled surface with the core bit perpendicular to the surface, then the machine can maintain stability on the surface, but the core bit becomes non-vertical leading to uneven core sides and bonding compound pooling

Engineering Contradiction:

Improvemachine stability on angled surfaceVSAvoidcore bit perpendicularity to horizon

Core Design Contradiction:

Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

The mast is made dynamically adjustable through a pivot mechanism that allows it to change its angular position relative to the machine frame. The angular adjustment mechanism with multiple lockable positions enables the operator to dynamically adapt the mast angle to compensate for surface inclination, ensuring the core bit remains vertical while the machine operates on angled surfaces.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If the core bit is oriented perpendicular to the angled surface, then the machine can maintain contact with the surface, but gravity causes bonding compound to pool and the bit to stick during reinstatement

Engineering Contradiction:

Improvemachine operation on angled surfaceVSAvoidcore extraction and reinstatement process

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The adjustable mast allows the core bit orientation to be dynamically corrected to remain vertical regardless of surface angle. This dynamic adjustment prevents bonding compound pooling and bit sticking by ensuring proper vertical orientation during reinstatement, while the machine itself can operate on various angled surfaces.

Inventive Principle:

Principle #15Dynamics

3Device complexity

If the mast is fixed in position, then the device structure remains simple, but the core bit cannot remain perpendicular to the horizon on angled surfaces

Engineering Contradiction:

Improvemast structure simplicityVSAvoidcore bit vertical orientation

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

Rather than a completely fixed mast, the invention implements a mast with controlled dynamic capability through the angular adjustment mechanism. This mechanism adds selective adjustability with lockable positions, providing the necessary vertical orientation capability while maintaining relative structural simplicity through a straightforward pivot and locking system.

Inventive Principle:

Principle #15Dynamics

AI summary

A mobile coring apparatus includes a machine frame including a mount, a mast pivotally connected to the mount and a coring assembly coupled to the mast. The coring assembly is configured to drive a core bit for coring through a surface. The pivotable mast allows for the core bit to remain perpendicular with the horizon when the mobile coring apparatus is used on an angled surface.
