Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If hydraulic pressure is used to generate torque in the impact device, then torque output is achieved, but torque adjustability is lost
Solution Approach 1:
The patent applies the dynamics principle by making the hydraulic pressure adjustable rather than fixed. The hydraulic pressure adjusting unit allows the hydraulic pressure to be dynamically changed according to different working conditions, enabling torque adjustment while maintaining the hydraulic torque generation mechanism. This transforms a static system into a dynamic one where key parameters can be modified to adapt to different requirements.
Solution Approach 2:
The patent directly implements parameter changes by providing a hydraulic pressure adjusting unit that modifies the hydraulic pressure parameter. By changing the hydraulic pressure from a fixed value to an adjustable parameter, the system can output different torque values to meet various user demands while still utilizing hydraulic pressure for torque generation.
2Adaptability or versatility
If hydraulic pressure adjusting unit is added to enable torque adjustment, then torque adjustability is improved, but device complexity increases
Solution Approach 1:
The hydraulic pressure adjusting unit is designed to perform multiple functions: it adjusts hydraulic pressure for torque control, and can potentially serve other pressure-related functions within the impact device. By making this component multi-functional, the patent reduces the need for additional separate components, thereby limiting the increase in device complexity while achieving torque adjustability.
