Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional mechanical thread connections are used to connect pipe parts, then the connection can be securely made, but the process is time-consuming and requires multiple field hands operating heavy equipment
Solution Approach 1:
The patent applies hydraulic principles by using a hydraulic grapple connector that is actuated by hydraulic pressure. The hydraulic system allows the grapple to open and close rapidly, enabling quick connection and disconnection of pipe segments without manual manipulation or heavy mechanical tools, thus dramatically reducing connection time while maintaining secure attachment
Solution Approach 2:
The invention replaces the conventional mechanical thread-based connection system with a hydraulic grapple connection system. Instead of using threaded assemblies that require manual tightening with tongs and wrenches, the system uses a hydraulically actuated grapple that can be opened and closed rapidly, substituting manual mechanical operations with automated hydraulic actuation
2Strength
If grapple type connection is used with hammering and tongs to secure the connection, then the pipe can be held securely, but the process involves safety hazards and requires multiple field hands
Solution Approach 1:
The hydraulic grapple connector is designed to secure itself to the pipe through hydraulic actuation. The system uses internal hydraulic pressure to automatically tighten and secure the grapple around the pipe, eliminating the need for multiple field hands to manually operate hammers and tongs. The self-securing mechanism reduces human exposure to safety hazards while maintaining strong connection
Solution Approach 2:
The patent uses hydraulic pressure to actuate the grapple mechanism, allowing it to close and secure around the pipe without manual hammering or tong operations. The hydraulic system provides controlled, consistent force that securely attaches the grapple to the pipe while eliminating the safety hazards associated with manual mechanical fastening operations
3Adaptability or versatility
If threaded assemblies are used for pipe connection, then the parts can be connected, but pipe rotation is required which complicates the connection process
Solution Approach 1:
The invention replaces the rotation-based threaded connection mechanism with a linear hydraulic grapple actuation system. The grapple opens and closes in a linear motion driven by hydraulic pressure, eliminating the need for pipe rotation or complex threading operations. This substitution simplifies the connection process while maintaining versatility in application
4Ease of manufacture
If conventional mechanical connection systems are used, then connections can be made, but heavy equipment and multiple field hands are required
Solution Approach 1:
The hydraulic grapple connector is designed as a multi-functional device that combines connection, sealing, and securing functions in a single integrated system. The universal hydraulic actuation mechanism can be applied to various pipe sizes and configurations, eliminating the need for multiple specialized tools and reducing the number of field hands required to operate the system
