Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mobile systems with lamps are used for lighting and heating the lawn, then grass growth is improved, but continuous operator monitoring and positioning is required
Solution Approach 1:
The system uses autonomous robots equipped with sensors, lamps, and heating elements that automatically navigate the lawn surface, detect grass growth needs, and apply treatments without human intervention. The robots self-coordinate their movements and operations based on real-time environmental sensing.
Solution Approach 2:
The patent replaces manual mechanical positioning systems with automated robotic platforms that use sensors, processors, and actuators to autonomously navigate and position themselves on the lawn surface based on detected grass conditions and growth requirements.
2Illumination intensity
If sodium lamps erected several meters above the ground are used, then grass coloring is improved, but heating and photosynthesis promotion are insufficient
Solution Approach 1:
The system employs multiple types of lamps (sodium lamps for coloring, LED lamps for photosynthesis, heating lamps for temperature) positioned at different heights and orientations above specific grass zones, allowing each area to receive the specific combination of light and heat it needs for optimal growth.
Solution Approach 2:
The patent combines multiple lamp technologies (sodium vapor lamps, LED lamps, heating lamps) in a single integrated system, allowing simultaneous achievement of grass coloring, photosynthesis promotion, and soil heating that cannot be achieved with a single lamp type.
3Adaptability or versatility
If multiple lamp types are used for different functions, then comprehensive grass treatment is achieved, but system complexity increases
Solution Approach 1:
The system divides the lawn into multiple zones and assigns different robot units with specialized lamp configurations to treat specific zones. Each robot carries a subset of lamp types (sodium, LED, heating) appropriate for its assigned area, reducing individual robot complexity while maintaining overall system versatility.
Solution Approach 2:
The patent designs robotic platforms with interchangeable lamp modules and adjustable positioning mechanisms that allow the same robot structure to perform multiple functions (lighting, heating, photosynthesis promotion) by changing lamp configurations rather than requiring dedicated robots for each function.
4Extent of automation
If automated positioning systems are implemented, then operator intervention is reduced, but device complexity increases
Solution Approach 1:
The system uses sensors to continuously monitor grass growth conditions, robot position, and environmental parameters, then feeds this information back to the control system which automatically adjusts robot positioning and lamp operation. This closed-loop control achieves high automation while using relatively simple sensor-controller-actuator circuits.
