Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual coating by workers suspended by ropes is used, then access to difficult surfaces is achieved, but productivity is very slow and worker safety is compromised
Solution Approach 1:
The patent replaces the manual mechanical system of workers suspended by ropes with an automated robotic system equipped with magnetic shoes that can adhere to and move along vertical and inclined surfaces autonomously, eliminating the need for human workers to physically access difficult surfaces while dramatically increasing coating productivity
Solution Approach 2:
The robotic system is self-propelled using omnidirectional wheels and self-positioned using magnetic shoes that adhere to ferromagnetic surfaces, allowing it to autonomously navigate and coat difficult surfaces without human intervention or external support structures
2Extent of automation
If fixed-base equipment is used for coating, then automation is achieved, but the infrastructure becomes too large and economically unfeasible for offshore environments
Solution Approach 1:
The patent divides the coating system into a mobile robotic unit that can independently navigate surfaces, eliminating the need for large fixed-base infrastructure. The robot is self-contained with all necessary components (magnetic shoes, omnidirectional wheels, coating apparatus) integrated into a single transportable unit
Solution Approach 2:
The patent transitions from ground-based fixed infrastructure to surface-based mobile operation by having the robot climb and move along vertical and inclined surfaces using magnetic adhesion, effectively utilizing the third dimension (height/verticality) to access and coat surfaces without requiring peripheral access from the deck or structure
3Productivity
If workers remain on platform for extended periods for coating, then coating is completed, but plant occupancy is reduced and access control is compromised
Solution Approach 1:
The patent replaces human workers with an autonomous robotic system that can perform coating operations without requiring extended presence on the platform, completing tasks faster and reducing the time occupation of specialized personnel while maintaining coating quality and completion

AI summary
The present invention aims at developing a robot for applying coating in regions called “difficult access areas” of offshore platforms and ships, such as curved, vertical surfaces, or surfaces with negative inclination angles. The design concept was developed based on a low-weight painting system, integrated into a vehicle with magnetic shoes (104), which produces a constant magnetic force on the metallic surface, capable of guaranteeing the support of the vehicle in the different areas of application. The floating magnetic system aims at ensuring that the wheels (102) have the necessary friction for the vehicle to move. The use of the equipment allows greater productivity, with agility and speed in the application of coatings, reduction of coating losses during the process, repeatability and guarantee of the thickness of the applied layer, in addition to allowing the application of the coating on vertical surfaces, with negative inclinations or curves, without the need for access using scaffolding, dispensing with scaffolding assembly and disassembly services and the use of ropes by professionals for work on the sea, with the consequent reduction in the number of workers on the sea and the reduction of exposure of the man in unhealthy environments.
