Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional shale shakers are used for sieving drilling fluid, then solid particles can be separated from the fluid, but the device transmits substantial vibrations to the base and generates high noise levels
Solution Approach 1:
The patent applies controlled mechanical vibration through a vibrating element that oscillates at specific frequencies to facilitate particle separation through the筛布, while the damping element absorbs excess vibrations to prevent transmission to the base, thus resolving the contradiction between separation efficiency and vibration/note control
Solution Approach 2:
The damping element acts as an intermediary between the vibrating sieving system and the base, absorbing and dissipating vibration energy to prevent harmful vibrations and noise from being transmitted to the surrounding environment while maintaining effective separation
2Reliability
If the sieving cloth is moved relative to the material to achieve sieving effect, then particles can be separated, but the sieving cloth is subjected to considerable wear and must be replaced frequently
Solution Approach 1:
The vibrating element induces oscillatory motion in the sieving cloth, creating dynamic separation conditions that reduce particle adhesion and minimize wear on the cloth surface, thereby extending its service life while maintaining separation efficiency
Solution Approach 2:
The periodic vibration applied to the sieving cloth creates alternating periods of high and low stress, preventing continuous wear in the same locations and reducing overall material degradation, thus extending the cloth's operational lifespan
3Adaptability or versatility
If high viscosity drilling fluid is used for drilling sandstone formations, then drilling can proceed, but conventional sieving apparatuses cannot provide enough gravitational forces to separate the drilling mud from solid particles
Solution Approach 1:
The vibrating element generates oscillatory forces that supplement gravitational forces, enabling effective separation of solid particles from high viscosity drilling fluid by creating dynamic motion that overcomes the increased bonding strength between mud and particles
Solution Approach 2:
The system changes the physical parameters of the separation process by introducing vibration frequency and amplitude as additional separation mechanisms, allowing effective processing of fluids with varying viscosities including high viscosity drilling muds that cannot be separated by gravity alone
4Reliability
If shale shakers are used for sieving, then drilling fluid can be cleaned, but hazardous substances evaporate to the immediate environment exposing personnel to health risks
Solution Approach 1:
The enclosure with sealed walls acts as a protective shell that contains the sieving process, preventing hazardous evaporation from reaching the environment and personnel while maintaining effective drilling fluid cleaning operations inside the enclosed space
Solution Approach 2:
The enclosure creates a controlled environment that isolates hazardous substances from the external atmosphere, effectively protecting personnel from exposure while allowing the cleaning process to proceed normally within the sealed space
