Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional intermittent drilling and cuttings removal mode is used, then equipment structure is simple, but drilling efficiency is low and time consumption is high
Solution Approach 1:
The patent merges the drilling function and cuttings removal function into a single integrated drill assembly. The drill assembly includes drilling teeth for cutting rock and a spiral blade for transporting cuttings, both operating simultaneously during continuous rotation. This eliminates the need to stop drilling for cuttings removal, achieving continuous drilling and cuttings discharge operations.
Solution Approach 2:
The drill assembly serves multiple functions: it drills through rock with drilling teeth, transports cuttings upward via the spiral blade, and enables continuous operation without interruption. The integrated design allows the same component to perform both cutting and material transport functions simultaneously, improving productivity without requiring separate equipment for each function.
2Productivity
If separate pouring tools are used after piling, then drilling equipment remains simple, but continuous pouring cannot be achieved and operation becomes intermittent
Solution Approach 1:
The patent combines the pouring function with the drill assembly by integrating a pouring mechanism that includes a pouring channel and control valve. The pouring channel is built into the drill assembly structure, allowing concrete to be delivered continuously through the same equipment used for drilling, eliminating the need to switch to separate pouring tools.
Solution Approach 2:
The drill assembly is designed to perform multiple operations sequentially or simultaneously: drilling with drilling teeth, transporting cuttings with the spiral blade, and pouring concrete through the integrated pouring channel. This multi-functional design enables continuous operation from drilling through to concrete pouring without equipment changes or operational interruptions.
3Reliability
If electrical structures are used in underground environment, then control functionality is advanced, but reliability decreases due to susceptibility to failure
Solution Approach 1:
The patent replaces electrical control structures with purely mechanical control mechanisms. The control valve for regulating concrete flow is operated mechanically through linkages connected to the drill assembly, eliminating the need for electrical motors, sensors, or control systems in the underground environment. This mechanical substitution improves reliability while maintaining adequate control functionality.
