Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If single charge and discharge mode is used, then device structure is simple, but drilling efficiency is low
Solution Approach 1:
The drilling system is divided into multiple independent drill rods (first drill rod, second drill rod, third drill rod, fourth drill rod), each with its own energy storage capacitor and discharge switch. This segmentation allows parallel operation of multiple drilling units, enabling continuous drilling while maintaining manageable individual component complexity.
Solution Approach 2:
The patent implements continuous drilling operation by coordinating multiple drill rods with different charge/discharge cycles. While one drill rod is discharging to break rock, others are charging or ready to discharge, ensuring uninterrupted drilling action and eliminating idle time between charges.
2Productivity
If multiple drill rods are used for continuous discharge, then drilling efficiency is improved, but control complexity increases
Solution Approach 1:
The control unit receives feedback signals from each drill rod's discharge status and energy storage capacitor charge level, automatically adjusting the discharge sequence and timing. This feedback mechanism coordinates the complex multi-rod operation without requiring manual intervention, managing control complexity through automated monitoring and adjustment.
Solution Approach 2:
The discharge sequence and timing of each drill rod are dynamically adjusted based on real-time operational conditions. The control unit can modify the discharge schedule of individual rods depending on rock hardness, drilling depth, and energy availability, optimizing performance while adapting to changing conditions.
3Duration of action of moving object
If alternate charging and discharging is implemented, then continuous drilling is achieved, but energy management complexity increases
Solution Approach 1:
Energy storage capacitors are charged in advance during periods when other drill rods are discharging or when drilling load is reduced. This preliminary charging action ensures that energy is ready and available when needed, enabling continuous operation without waiting for sequential recharge of a single rod.
Solution Approach 2:
The system recovers and stores energy from the power supply across multiple capacitors in parallel, distributing the energy storage burden. When one capacitor is discharged, others can be charged or are already charged and ready, creating a rotating energy supply system that maintains continuous operation.

AI summary
Disclosed is a pulse drilling device, including: a plurality of drill rods (100), a plurality of drill bits, a plurality of energy storage capacitors (300) and a plurality of discharge switches (400). Each of the drill rods is correspondingly connected to the energy storage capacitor, the energy storage capacitor is configured to charge the drill rod connected to the energy storage capacitor, the drill bit is connected to the drill rod, the discharge switch is connected to the drill rod to control the drill rod to discharge to the drill bit to break rocks, and the plurality of the drill rods are configured to continuously and alternately charge and discharge. The discharge switch can control the charging state of each of the drill rods correspondingly. When one of the drill rods is in the discharging state, the other drill rods are in the charging state. The drill rod in the discharging state switches to the charging state after the electric energy is exhausted, and at the same time, the drill rod in the fully charged state is continuously discharged. As a result, the plurality of drill rods can be continuously charged and discharged alternately, thereby greatly improving the drilling efficiency.
