1Productivity

If manual sampling is conducted in high-risk production areas, then sampling can be performed, but staff safety is compromised and labor intensity increases

Engineering Contradiction:

Improvesampling efficiencyVSAvoidstaff safety risk

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces manual mechanical sampling operations with an automated robotic system that uses mechanical arms and automated valves to perform sampling tasks remotely, eliminating staff exposure to high-risk environments while maintaining sampling efficiency

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The robotic system acts as an intermediary between the operator and the hazardous sampling environment, allowing staff to control sampling operations remotely through a control system that interfaces with the robot's mechanical components and sensors

Inventive Principle:

Principle #24Intermediary (Mediator)

2Extent of automation

If electromagnetic valves are installed at transformer oil sampling sites, then automated sampling can be achieved, but installation and maintenance costs increase

Engineering Contradiction:

Improveautomated sampling capabilityVSAvoidinstallation and maintenance cost

Core Design Contradiction:

Extent of automationVSEase of manufacture

Solution Approach 1:

The robotic system is designed with universal, multi-functional components that can perform multiple sampling operations across different transformer types and locations, eliminating the need for site-specific electromagnetic valve installations and reducing overall system complexity and cost
