Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sensor positioning system is deployed in open ocean aquaculture, then sensor data capture capability is improved, but the system becomes vulnerable to rotational disturbances from external forces like ocean currents and winds
Solution Approach 1:
The patent employs a counterbalancing mechanism where a counterweight is attached to the sensor positioning system to offset the rotational disturbances caused by ocean currents and winds. The counterweight creates an opposing moment that balances the destabilizing forces, allowing the sensor system to maintain stable positioning and continuous data capture capability despite external environmental forces.
2Reliability
If traditional bracing components are used in the sensor positioning system, then the system structure is simple, but the system cannot effectively resist torquing from external forces requiring frequent manual maintenance
Solution Approach 1:
The patent transitions from static traditional bracing components to a dynamic bracing system that can actively respond to external forces. The dual bracing components are designed with adjustable characteristics that allow them to adapt their stiffness and positioning in response to varying ocean currents and winds, enabling effective resistance to torquing while maintaining manageable system complexity through controlled adaptability.
3Stability of the object's composition
If the sensor positioning system uses dual bracing components with winch actuation, then stability against external forces is improved, but the system requires more complex actuation mechanisms
Solution Approach 1:
The patent integrates the winch actuation system to serve multiple functions simultaneously: it provides active positioning of the sensor system, adjusts the tension in dual bracing components, and enables the system to maintain stability against external forces. This multi-functionality reduces the need for separate dedicated mechanisms for each function, managing overall system complexity while achieving enhanced stability through a unified actuation platform.
