Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual repair methods are used for deep-water cage nets, then personnel can perform repairs, but the repair efficiency is low and safety risks are high due to complex seabed environment and human body limitations
Solution Approach 1:
The patent replaces manual mechanical repair operations with an automated underwater robot system. The robot integrates hole-penetrating mechanisms, wire feeding mechanisms, rotary knotting mechanisms, and wire cutting mechanisms to automatically perform net repair tasks, eliminating the need for human divers in harsh underwater environments and significantly improving both safety and efficiency
Solution Approach 2:
The underwater robot is equipped with integrated self-contained mechanisms including wire feeding, knotting, and cutting functions that operate autonomously without requiring human intervention during the repair process, enabling the system to service itself and perform complete repair cycles independently
2Productivity
If conventional manual repair is used, then simple equipment is needed, but the repair quality and efficiency remain low due to human body function limitations
Solution Approach 1:
The patent combines multiple repair functions (hole penetration, wire feeding, knotting, and cutting) into a single integrated underwater robot system. This merging of functions allows the device to perform complete repair operations automatically, significantly improving efficiency while the modular design keeps maintenance manageable
Solution Approach 2:
The underwater robot is designed as a multi-functional device that can perform various repair operations including penetrating holes in nets, feeding repair wires, tying knots, and cutting excess wire. This universal capability allows a single device to handle different repair scenarios, improving overall productivity despite increased complexity
3Ease of operation
If modular assembly is used to assemble the underwater robot and repairing mechanism, then disassembly and assembly become convenient and transport safety is improved, but device complexity increases
Solution Approach 1:
The patent divides the underwater robot system into modular components including the main robot body, hole-penetrating mechanism, wire feeding mechanism, rotary knotting mechanism, and wire cutting mechanism. Each module can be independently assembled, tested, and maintained, making the complex system manageable through standardized interfaces and reducing overall assembly complexity
