Solution Overview

Problem

Current methods for removing fluids from underwater containers, such as shipwreck tanks, are complex and prone to errors due to poor visibility and the risk of oil leakage during equipment changes, increasing the likelihood of environmental damage.

Innovation Solution

A device with a drill bit having multiple sections (spotting, twist, and tap drill) and a suction device that surrounds the drill bit, allowing immediate suction upon puncturing the container, reducing the need for tool changes and minimizing oil escape, equipped with indicators for safe operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If drilling equipment is removed and suction equipment is placed to the drilled hole, then fluid can be removed from the container, but oil may escape the suction equipment during equipment changes

Engineering Contradiction:
Improvefluid containment reliabilityVSAvoidequipment change complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the drilling function and suction function into a single integrated device. The drill bit with flutes is integrated with the suction device, allowing the drill to create the hole and the suction device to immediately capture fluid without removing equipment. This merging eliminates the equipment change step that causes oil escape and reduces operational complexity.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If multiple tool changes are conducted during drilling procedure, then different drilling functions can be performed, but the risk of hazardous fluid leaking into the environment increases

Engineering Contradiction:
Improvedrilling function versatilityVSAvoidfluid leakage risk
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent integrates multiple drilling functions (spotting, twisting, and tapping) into a single multi-section drill bit. The drill bit includes a spotting drill section for initial penetration, a twist drill section for enlarging the hole, and a tap drill section for threading. This integration allows versatile drilling operations without removing or changing tools, eliminating leakage risks during equipment changes.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The suction device operates continuously throughout the entire drilling process, from initial penetration to final threading. The suction begins when the spotting drill section penetrates the container and continues without interruption as the drill progresses through different sections. This continuous operation ensures no fluid escape occurs during the drilling procedure.

Inventive Principle:
Principle #20Continuity of useful action

3Productivity

If the drill bit has multiple sections for different drilling steps, then the drilling process can be completed without tool changes, but the device structure becomes more complex

Engineering Contradiction:
Improvedrilling process efficiencyVSAvoiddrill bit structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The drill bit is segmented into distinct functional sections: a spotting drill section for initial penetration, a twist drill section for enlarging the hole, and a tap drill section for threading. Each section performs a specific drilling function, allowing the complete drilling process to be completed with one tool while maintaining clear functional separation. This segmentation achieves productivity improvement without excessive complexity.

Inventive Principle:
Principle #1Segmentation
