Cutting Chain Drilling Device for Large Object Sampling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current drilling methods are inefficient and destructive for large objects, as they grind and damage samples, and sawing methods cannot access all areas, leading to high costs and sample preservation issues.
Innovation Solution
A singular drilling and cutting device with a cutting chain and polyhedron-shaped cutting elements, driven by a gear and motor, allowing for lateral, longitudinal, and rotational movement to create precise holes and cuts without damaging the object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If current drilling methods are used, then holes can be drilled through large objects, but the cutting elements are consumed and samples are damaged
Solution Approach 1:
The cutting chain is divided into multiple discrete cutting elements spaced along the chain, allowing selective engagement with the workpiece. This segmentation enables precise cutting actions that remove material efficiently while preserving sample integrity, as each cutting element can be positioned to make clean cuts rather than grinding continuously
Solution Approach 2:
Instead of using a traditional rotating drill bit that grinds material away, the invention uses a chain moving in the opposite direction with cutting elements that engage the workpiece in a pulling motion. This inversion of the cutting mechanism allows for cleaner cuts that preserve samples while maintaining drilling productivity
2Manufacturing precision
If sawing methods are used, then samples can be cut from large objects, but access to two or more sides is required
Solution Approach 1:
The invention transitions from the traditional two-dimensional sawing approach (requiring access to two sides) to a three-dimensional drilling approach using a cutting chain. The chain can be fed through a single access point and rotate to cut through the workpiece from multiple angles, enabling sample extraction from large objects with limited accessibility
Solution Approach 2:
The cutting chain device serves multiple functions: it can drill holes, cut samples, and access confined spaces within large objects. This multi-functionality replaces the need for separate sawing equipment and provides versatility in handling different sampling scenarios from a single access point
3Volume of moving object
If multiple cutting elements are used, then large holes can be drilled, but the cost increases significantly
Solution Approach 1:
The cutting chain is designed to be reusable with cutting elements that can be recovered, inspected, and replaced individually rather than discarding the entire drilling system. This allows for cost-effective drilling of large holes by maintaining the chain and replacing only worn cutting elements, reducing the overall quantity of consumables needed
Solution Approach 2:
The cutting chain provides continuous cutting action as it rotates and feeds through the workpiece, eliminating the need to stop and change cutting elements frequently. This continuous operation enables efficient drilling of large holes while minimizing the total number of cutting elements required compared to intermittent drilling methods

AI summary
A drilling and cutting device for both drilling and cutting through large objects is provided. The drilling and cutting device provides a plurality of cutting elements spaced apart and connected along a cutting chain that is operatively connected to a driven gear. The cutting chain is mounted along a periphery of a guide bar adapted to force the cutting chain to move on a certain path laterally, longitudinally or rotatably when selectively engaged to a mounting assembly.
