Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual labor is used for bolt retightening on electric angle steel towers, then the operator can perform the task, but the process has high danger coefficient, high labor intensity, long idle time, and low efficiency
Solution Approach 1:
The climbing robot is equipped with self-clamping mechanisms that automatically grip the angle steel tower surface using friction forces, and self-positioning capabilities through mechanical structures, enabling the system to service itself without external assistance during the bolt retightening operation
Solution Approach 2:
The patent replaces the manual mechanical system with an automated robot system that uses electric push rods, rotating mechanisms, and computer-controlled actuators to perform bolt retightening, substituting human physical labor with automated mechanical and electrical systems
2Adaptability or versatility
If conventional climbing robots are used for bolt retightening, then automation is achieved, but the cost performance is poor when dealing with different bolt types
Solution Approach 1:
The robot system is divided into modular components including separable socket tools, independent displacement mechanisms, and detachable working heads, allowing individual sockets to be replaced without reconfiguring the entire system, thus improving adaptability while controlling complexity
Solution Approach 2:
The robot is designed with universal interfaces and standardized mounting mechanisms that can accommodate different types of sockets and bolt configurations through a single platform, enabling one deployment to service multiple bolt types and spans
3Ease of operation
If manual bolt retightening is performed at high altitude, then the task can be completed, but the process is labor-intensive and time-consuming
Solution Approach 1:
The robot system maintains continuous operation capability with integrated power supply, continuous climbing mechanisms, and uninterrupted tool operation, eliminating idle time between tasks and maintaining productive action throughout the entire maintenance process
Solution Approach 2:
The robot acts as an intermediary between the operator and the high-altitude environment, performing dangerous tasks in harsh conditions while the operator remains safely on the ground, thus improving ease of operation and safety
