Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing core drill bits lack efficient means for tracking the usage and performance of abrasive cutting segments, leading to suboptimal operation and maintenance, as they do not have integrated systems for data storage and communication of operational parameters.
Innovation Solution
A core drill bit design featuring a tubular shaft with a mounting platform, an annular cutting section equipped with abrasive segments, and a transponder system for data storage and communication, allowing for the reading of operational data and enabling remote monitoring without a power supply, using passive transponders and repeaters for radio signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a transponder system with data storage is integrated into the drill bit for tracking operational parameters, then measurement precision and information availability are improved, but device complexity increases
Solution Approach 1:
The patent embeds a first transponder with data storage inside the annular cutting section, and a second transponder with antenna inside the tubular shaft. The nested arrangement allows both transponders to coexist in a compact configuration, enabling data storage and wireless communication functions without significantly increasing overall device complexity
Solution Approach 2:
The patent introduces a repeater as an intermediary device that receives signals from the first transponder and retransmits them to the machine tool. This mediator enables long-range wireless communication while keeping the first transponder simple and integrated within the cutting section
2Ease of operation
If a passive transponder system is used for remote monitoring without power supply, then ease of operation is improved, but the ability to transmit complex operational data is limited
Solution Approach 1:
The first transponder continuously stores operational parameters such as torque, speed, and usage time in its data storage memory during drilling operations. This preliminary data accumulation ensures that comprehensive information is available for later retrieval, even though the transponder itself requires no power supply
Solution Approach 2:
The system creates a digital copy of operational data in the transponder's data storage, which can be retrieved and transmitted without consuming additional power. This allows the passive transponder to provide complete operational information without requiring active power during data transmission
3Adaptability or versatility
If the annular cutting section is made releasably mounted for replacement, then adaptability is improved, but reliability of the transponder connection may worsen
Solution Approach 1:
The first transponder is nested inside the annular cutting section, protected within its structure. The second transponder is nested inside the tubular shaft with its antenna positioned to face the first transponder. This nested configuration ensures that the transponders remain properly aligned and connected even when the cutting section is replaced
Solution Approach 2:
The repeater system provides continuous wireless communication between the transponders and the machine tool, enabling real-time monitoring of the cutting section's operational status. This feedback mechanism ensures reliable data transmission regardless of mechanical connection changes during cutting section replacement
