Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water absorption and drainage method is used to control sinking and floating, then the robot can change its quality to achieve floating or sinking, but the process takes a long time resulting in decreased working efficiency
Solution Approach 1:
The patent changes the physical state of the airbag from deflated to inflated to alter the robot's overall volume and buoyancy. By inflating the airbag, the robot's displacement increases, providing sufficient buoyancy to float on water surface or climb out of the pool, thereby achieving rapid sinking and floating control without the time-consuming water absorption and drainage process
Solution Approach 2:
The patent introduces an airbag system that uses pneumatic pressure to control the robot's floating and sinking states. The airbag can be rapidly inflated with air to increase buoyancy and deflated to decrease buoyancy, enabling fast response for sinking and floating operations and significantly improving working efficiency compared to water-based ballast systems
2Reliability
If water absorption and drainage method is used, then the robot can control its sinking and floating states, but the internal component configuration becomes complex
Solution Approach 1:
The patent extracts the water-based ballast system and replaces it with an airbag system. By removing the complex water absorption and drainage mechanisms, the internal component configuration is simplified while maintaining reliable sinking and floating control through the pneumatic airbag system
Solution Approach 2:
The patent changes the control mechanism from water mass variation to air volume variation in the airbag. This parameter change simplifies the system by eliminating the need for water intake and drainage components, reducing internal complexity while achieving the same functional outcome of controllable buoyancy
