Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional drilling machine with handle-based elevation regulation is used, then the structure is simple, but the machining efficiency is low and drilling precision is poor
Solution Approach 1:
The patent replaces the conventional mechanical handle-based elevation regulation system with a computerized numerical control system. The drilling depth and angle are controlled through programmable parameters rather than manual mechanical adjustments, significantly improving machining efficiency and precision while reducing process complexity through automation.
Solution Approach 2:
The invention implements variable parameter control for drilling operations, including adjustable drilling angles, depths, and speeds through numerical control. This allows optimization of drilling parameters for different vent hole requirements, improving both efficiency and precision compared to fixed-parameter conventional machines.
2Manufacturing precision
If a high-end five-axis linkage machining center is used for drilling, then the machining precision can be improved, but the device complexity increases and occupancy space expands
Solution Approach 1:
The patent segments the five-axis linkage system into modular functional units: a drilling unit with spindle and drill bit, a positioning unit with X-Y-Z axes, and a control unit with numerical control system. This modular segmentation achieves high precision hole diameter consistency while reducing overall device complexity and occupancy space compared to integrated five-axis machining centers.
Solution Approach 2:
The drilling machine is designed with multi-functional capabilities including drilling at various angles, adjustable depth control, and automated positioning. This universal design allows a single machine to perform multiple drilling operations that would otherwise require different specialized equipment, reducing device complexity while maintaining high precision.
3Manufacturing precision
If manual handle operation is used for drill elevation regulation, then the device complexity is low, but the drilling precision and angle control are poor
Solution Approach 1:
The patent replaces manual handle-based mechanical elevation regulation with a numerical control system that electronically controls drill position and angle. This substitution achieves precise drilling angle control through programmable parameters while the control system automates operations, reducing the complexity of manual handling.
