Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external vacuum sources and large fluid supplies are used for drilling operations, then debris removal and lubrication/cooling functions are achieved, but cleanup requirements and manufacturing costs increase
Solution Approach 1:
The patent combines the vacuum passage and fluid passage into a single integrated tool body, allowing simultaneous debris removal and fluid delivery through coordinated passages. The vacuum passage removes debris while the fluid passage delivers lubrication/cooling fluid, and both functions work together more efficiently than separate external systems.
Solution Approach 2:
The tool is designed to be self-sufficient by integrating both vacuum and fluid delivery capabilities within the tool body itself, eliminating the need for extensive external vacuum sources and large fluid supply systems. The tool serves its own debris removal and lubrication needs through its internal passage system.
2Reliability
If external vacuum sources are used to remove debris, then debris removal is achieved, but device complexity and setup requirements increase
Solution Approach 1:
The patent merges the vacuum delivery system and fluid delivery system into a single integrated tool assembly. Both passages originate from the tool body and work in coordination, simplifying the overall system architecture compared to separate external vacuum sources and fluid supply systems.
Solution Approach 2:
The tool body serves multiple functions simultaneously: it delivers cutting fluid through the fluid passage, removes debris through the vacuum passage, and provides structural support for the cutter. This multi-functionality reduces the need for separate specialized equipment.
3Temperature
If large amounts of fluid are supplied for lubrication and cooling, then lubrication and cooling functions are achieved, but cleanup requirements and manufacturing lead times increase
Solution Approach 1:
The tool integrates fluid delivery and vacuum removal capabilities, allowing it to manage its own thermal management and debris removal needs during processing. This self-service capability eliminates post-processing cleanup steps and reduces manufacturing lead time.
Solution Approach 2:
The integrated system allows continuous operation during the drilling process with fluid being delivered and debris being removed simultaneously throughout the operation, rather than requiring separate fluid application and subsequent cleanup steps, thereby reducing total manufacturing time.
