Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an irreversible gear transmission with clutch is used, then the feeding motor can be disengaged from the feeding mechanism, but the system becomes complicated, costly, and heavy
Solution Approach 1:
The patent removes the clutch component entirely from the system. The feeding motor is permanently coupled to the gear transmission through a planetary gear set, eliminating the need for engagement/disengagement mechanisms while maintaining the ability to manually override the system by turning the rack gear directly.
Solution Approach 2:
The rack gear serves dual functions: it can be rotated by the feeding motor through the planetary gear transmission for automated feeding, or it can be manually rotated by the operator for manual positioning. This multi-functionality replaces the need for a clutch mechanism.
2Ease of operation
If a worm gear transmission is used, then the feeding motor can be disengaged, but the transmission efficiency is low and feeding speed is limited
Solution Approach 1:
The patent replaces the worm gear transmission with a planetary gear set. Planetary gears provide higher mechanical efficiency and can handle higher speeds compared to worm gears, while still providing the necessary gear reduction and torque multiplication for the feeding mechanism.
Solution Approach 2:
The patent changes the gear transmission parameters by using a planetary gear set with specific tooth configurations that allow for higher efficiency and speed. The gear ratio and mechanical efficiency are optimized to enable faster feeding speeds while maintaining adequate torque.
3Loss of energy
If a planetary gear with angle gear is used, then the gear can be turned by hand and efficiency is higher, but the design becomes more complex
Solution Approach 1:
The angle gear (bevel gear) acts as an intermediary element that transfers motion between the horizontal axis of the rack gear and the vertical axis of the planetary gear set. This allows the manually rotatable rack gear to drive the planetary gears, which then drive the feeding motor or feeding mechanism, achieving high efficiency while maintaining manual operability.
4Adaptability or versatility
If remote wireless control is implemented, then the operator can control the drilling device in hazardous or inaccessible areas, but the control system becomes more complex
Solution Approach 1:
The patent replaces direct mechanical or wired control with wireless electronic control. A remote control device communicates with the drilling machine's control system via wireless signals, allowing the operator to control feeding speed, direction, and drilling parameters from a safe distance without complex wiring or mechanical linkages.
