Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual work is used to add insulating protective covers over parallel groove clamps, then insulation protection is provided, but operational efficiency is low and the effectiveness of insulation protection cannot be guaranteed
Solution Approach 1:
The patent replaces the manual mechanical process of adding insulating protective covers with an automated coating device that applies liquid insulating material. The device includes a coating mechanism with spray nozzles and a curing mechanism with heating elements, automating the entire insulation process and eliminating manual labor while ensuring consistent application quality and effectiveness.
Solution Approach 2:
The patent changes the state of insulating material from solid protective covers to liquid coating material that can be sprayed and then cured. This parameter change allows for automated application through spraying, ensures uniform coverage, and enables controlled curing through temperature or UV treatment, thereby improving both efficiency and reliability of insulation protection.
2Extent of automation
If robotic operations are used to secure grounding wires, then operational safety is improved and efficiency is increased, but subsequent manual work is still required for insulation
Solution Approach 1:
The patent merges the robotic wire-securing operation with the insulation application process by integrating the coating device into the robotic system. The coating mechanism is positioned to work immediately after the clamp is secured, and the curing process is initiated automatically, combining multiple operations into a single automated workflow that reduces process complexity despite increased automation extent.
Solution Approach 2:
The patent ensures continuous automated operation by immediately applying the liquid insulating material after the robotic clamp installation, without requiring manual intervention. The curing process follows automatically, maintaining continuous useful action throughout the entire process from clamp installation to final insulation, thereby managing device complexity while maximizing automation extent.
