Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional drilling pump transmission system is used, then power transmission is achieved, but transmission efficiency is low and equipment weight is heavy
Solution Approach 1:
The patent removes the intermediate transmission components (parallel box, chain box, belts, chains) from the power transmission system, directly coupling the diesel engine to the mud pump group. This extraction of unnecessary transmission elements eliminates energy losses and reduces equipment weight while maintaining power transmission capability.
Solution Approach 2:
The patent merges the previously separate components (engine, transmission boxes, belts, chains, mud pump group) into a directly coupled integrated system. By combining these elements into a unified power transmission arrangement, the system achieves higher efficiency and reduced weight.
2Power
If conventional drilling pump transmission system is used, then power transmission is achieved, but floor space is large
Solution Approach 1:
The patent extracts and removes the bulky intermediate transmission components (parallel box, chain box, belts, chains) that occupied significant floor space. The direct coupling arrangement requires minimal space while maintaining full power transmission capability.
Solution Approach 2:
By merging all power transmission elements into a compact directly coupled system, the patent reduces the spatial footprint required for power transmission while preserving the necessary power delivery to the mud pump group.
3Power
If conventional drilling pump transmission system is used, then power transmission is achieved, but operation and maintenance workload is heavy
Solution Approach 1:
The patent removes the complex intermediate transmission system requiring extensive operation and maintenance (parallel box, chain box, belts, chains). The direct coupling eliminates these components, significantly reducing operational complexity and maintenance requirements while maintaining power transmission.
Solution Approach 2:
By integrating all power transmission functions into a simple directly coupled system, the patent minimizes the number of moving parts and potential failure points, thereby reducing operation and maintenance workload.
