Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a hydraulic drive system is used in the nail punching machine, then sufficient driving force can be achieved, but the device complexity increases due to hydraulic lines and the ease of operation deteriorates due to operator fatigue and discomfort
Solution Approach 1:
The patent replaces the hydraulic drive system with an electric drive motor. The electric motor directly drives the driving mechanism through a mechanical connection, eliminating the need for hydraulic lines and fluid power transmission. This substitution reduces device complexity and improves operator comfort while maintaining sufficient driving force for punching rail spikes.
2Power
If a hydraulic drive system is used, then the driving mechanism can be powered, but the device complexity increases due to the presence of hydraulic lines
Solution Approach 1:
The patent substitutes the complex hydraulic power transmission system with a simpler electric motor and direct mechanical connection. The electric motor is mounted on the machine body and connects directly to the driving mechanism, eliminating hydraulic pumps, valves, lines, and fluid management systems, thereby significantly reducing device complexity while maintaining adequate power delivery.
Solution Approach 2:
The patent extracts and removes the hydraulic system components (hydraulic lines, hydraulic pump, hydraulic fluid) from the nail punching machine. By eliminating these components and replacing them with an electric motor, the patent simplifies the overall device structure and reduces maintenance requirements while preserving the essential driving function.
3Power
If the driving mechanism is directly connected to the handle, then power transmission is efficient, but vibrations are transmitted to the operator reducing user comfort
Solution Approach 1:
The patent introduces a vibration decoupling device as an intermediary element between the driving mechanism and the handle. This device allows power transmission from the electric motor to the driving mechanism while simultaneously decoupling and dampening vibrations, preventing them from being transmitted to the operator's hands and arms during operation.
