Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a traditional spraying robot is used for operation, then spraying automation is achieved, but the work space is limited, mechanical efficiency is low, and tail-end operation accuracy is poor
Solution Approach 1:
The patent replaces traditional rigid mechanical arm structures with a rope traction system that uses flexible cables and pulleys. This substitution allows the spray gun to achieve greater workspace flexibility and mobility while maintaining automated spraying capability, directly resolving the contradiction between automation extent and workspace adaptability
Solution Approach 2:
The patent employs flexible ropes and cables instead of rigid mechanical linkages to connect the spray gun to the driving mechanism. This flexible transmission system enables the spray gun to navigate complex three-dimensional spaces and access difficult-to-reach areas, significantly expanding the effective workspace while preserving automated operation
2Reliability
If separate machines are used for grinding, cleaning and spraying, then each operation can be performed by specialized equipment, but the operation process becomes complex and efficiency is low
Solution Approach 1:
The patent integrates grinding, cleaning, and spraying operations into a single unified robot system. The spray gun assembly incorporates multiple functional components that can perform different operations sequentially or simultaneously, eliminating the need for multiple separate machines and reducing operational complexity while maintaining specialized capabilities
Solution Approach 2:
The patent designs a multi-functional spray gun system that can perform grinding, cleaning, and spraying operations using a single integrated platform. The system includes interchangeable or adjustable components that allow one device to execute multiple functions, thereby improving productivity by eliminating machine changes and setup time
3Adaptability or versatility
If a robot changes working heads with different functions, then different machining requirements can be met, but the machining efficiency is reduced
Solution Approach 1:
The patent implements a universal spray gun system with integrated multi-functionality, where a single device can perform grinding, cleaning, and spraying operations. This eliminates the need to change working heads between different operations, maintaining adaptability to various machining requirements while continuously improving machining efficiency by avoiding head changeover time
4Reliability
If electromagnetic adsorption is used for wall climbing, then the robot can adhere to vertical surfaces, but electric energy is needed to maintain adsorption capacity, limiting working capacity
Solution Approach 1:
The patent replaces electromagnetic adsorption with a mechanical rope traction system for wall climbing. The robot uses ropes and pulleys to ascend and adhere to vertical surfaces, eliminating the need for continuous electric energy consumption to maintain adsorption. This mechanical approach provides reliable wall climbing capability while significantly reducing energy requirements

Function Achieved in This Case
The integrated robot achieves improved efficiency, stability, and quality by enabling flexible operation on large and irregular surfaces while effectively managing reaction forces, reducing vibration, and ensuring accurate location and operation.
Implementation Method 1
The spring reaction force regulation mechanism includes a third vertical plate that is parallel to the second vertical plate; the second vertical plate is located between the first vertical plate and the third vertical plate, and may move in the front-back direction of the hanging basket. The third vertical plate is fixedly connected to the hanging basket. A telescopic rod and a second traction mechanism for connecting the first vertical plate and the second vertical plate are arranged therebetween. The stretching and contracting of the telescopic rod make the first vertical plate move back and forth relative to the hanging basket. The second traction mechanism controls the first vertical plate to realize the adjustment of a pitch angle. A rigid rod for connecting the third vertical plate and the second vertical plate and a third traction mechanism are arranged therebetween; one end of the rigid rod is fixedly connected to the second vertical plate; the other end of the rigid rod is connected to springs arranged on the third vertical plate after penetrating through the third vertical plate vertically. The thrust and reaction force stressed on the cleaning and spraying mechanism may be balanced by the change of lengths of the springs and the change of an included angle between each of the springs and the rigid rod.
Implementation Method 2
The rope traction type robot integrating grinding, cleaning, and coating operations with a hanging basket, traction mechanisms, and a spring reaction force regulation system, allowing for three degrees of freedom movement and balancing thrust and reaction forces through magnetorheological dampers and spring mechanisms.
