Multi-Outlet Tool Bit for Precise Fluid Delivery in Drilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drill bits deliver fluids to workpieces through the cutting tip, which can limit the effectiveness of fluid distribution and lead to inefficiencies in debris removal and lubrication during the drilling process.
Innovation Solution
A tool bit design featuring an internal cavity with transverse channels and outlets spaced from the tip, allowing fluid to be delivered to the workpiece from a location away from the cutting tip, enabling more controlled and efficient application of fluids during drilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fluid is delivered through the cutting tip, then the fluid delivery structure is simple, but the fluid distribution effectiveness is limited
Solution Approach 1:
The tool bit is segmented into multiple functional zones: a cutting tip portion and a body portion with multiple outlets. The outlets are spaced apart from the cutting tip, allowing fluid to be delivered to different locations on the workpiece surface simultaneously, improving fluid distribution effectiveness without excessive complexity
Solution Approach 2:
The invention transitions from single-point fluid delivery at the cutting tip to multi-point fluid delivery along the body of the tool bit. By spacing outlets at different positions, the system adds spatial dimensionality to fluid delivery, enabling broader coverage and more effective distribution across the workpiece surface
2Manufacturing precision
If outlets are spaced from the cutting tip, then fluid delivery accuracy is improved, but the device complexity increases
Solution Approach 1:
The internal cavity and multiple channels are merged into a single integrated body structure. The cavity serves as a common fluid reservoir that feeds all outlets through branching channels, allowing precise positioning of multiple outlets without requiring separate complex delivery systems for each outlet
Solution Approach 2:
The internal cavity serves multiple functions: it acts as a fluid reservoir, a structural support element, and a distribution hub for multiple channels. This multi-functionality reduces the need for additional separate components, managing device complexity while enabling precise fluid delivery to multiple locations
3Reliability
If multiple outlets are used, then fluid distribution effectiveness is improved, but fluid waste increases
Solution Approach 1:
Different outlets are positioned at specific locations to deliver fluid precisely where needed on the workpiece surface. The spacing and positioning of outlets are optimized to target specific zones, ensuring fluid is applied locally where it provides maximum benefit rather than being wasted in unnecessary areas
Solution Approach 2:
The system uses multiple outlets to deliver fluid to multiple locations simultaneously, but each outlet delivers a controlled amount of fluid appropriate for its specific location. This partial action at multiple points achieves better overall distribution effectiveness without the excessive fluid application that would result from a single high-flow outlet

AI summary
A tool bit includes a body having an internal cavity extending along a longitudinal axis between a first distal end and a second distal end. A plurality of channels of the body extend transverse from the internal cavity of the body. The first distal end includes an inlet in fluid communication with the internal cavity and the plurality of channels. The body includes an outer surface having a plurality of outlets spaced from the second distal end. Each one of the plurality of outlets is in fluid communication with a corresponding one of the plurality of channels such that a fluid is deliverable into the body via the inlet and out of the body via the plurality of outlets. A tooling assembly for applying a fluid to a surface includes a workpiece and the tool bit as discussed above which is movable relative to the workpiece.
