Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional twist drilling is used to machine ceramic materials, then the drilling operation can be performed, but the drill slips resulting in inclined cavity, poor roundness, and difficulties in cuttings exclusion
Solution Approach 1:
The patent applies ultrasonic vibration to the drill bit, causing it to vibrate at high frequency during the drilling operation. This vibration prevents the drill from slipping on the ceramic material surface, thereby eliminating inclined cavities and improving roundness while facilitating cuttings exclusion through the vibratory motion.
2Manufacturing precision
If ultrasonic vibration machining is applied to improve machining quality, then surface quality and machining efficiency are enhanced, but the equipment cost increases significantly
Solution Approach 1:
The patent divides the ultrasonic vibration system into modular components: a vibration generator module that can be attached to existing drilling machines. This segmentation allows the expensive ultrasonic technology to be added as a separate module rather than requiring complete equipment replacement, thereby reducing overall system cost while maintaining machining quality improvements.
Solution Approach 2:
The vibration generator module is designed to be universally compatible with various drilling machine types and tool holders. This multi-functionality allows a single ultrasonic module to serve multiple machining operations and be installed on different existing machines, amortizing the equipment cost across multiple applications and reducing the per-operation cost.
3Productivity
If ultrasonic vibration tool is used for machining, then machining efficiency is improved, but safety concerns arise due to improper power connection and water outlet design
Solution Approach 1:
The patent incorporates preliminary safety design features in the power connection mechanism and water outlet positioning. The power connection is designed with automatic engagement and interlocking mechanisms that ensure proper connection before operation begins. The water outlet is pre-positioned and protected to prevent exposure during rotation, eliminating safety hazards before they can occur during machining operations.
