Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed voltage converter is used to step up system voltage to high voltage for spray charging, then the spray particles can be attracted to the user as desired, but the attraction is not optimized for current session variables and cannot be actively monitored or adjusted over time
Solution Approach 1:
The patent implements a dynamic voltage adjustment system that transitions from fixed voltage to adjustable voltage operation. The controller actively modifies the output voltage of the spray charging system based on real-time feedback from sensors monitoring spray deposition quality, user feedback, and environmental conditions, enabling the system to adapt to changing variables during different spray sessions
Solution Approach 2:
The patent incorporates multiple feedback mechanisms including sensors that detect spray deposition quality, users' stance position, and environmental factors. This feedback is processed by the controller which adjusts the voltage output accordingly, creating a closed-loop control system that continuously optimizes spray particle attraction without requiring manual intervention
2Reliability
If fixed voltage is applied to the spray mechanism, then the system is simple to operate, but sufficient feedback is not provided to make suitable adjustments during the spray pass
Solution Approach 1:
The system performs self-optimization by automatically adjusting voltage based on sensor feedback without requiring manual intervention. The controller monitors spray deposition quality and environmental conditions, then autonomously modifies voltage parameters to maintain optimal spray application consistency throughout the session
Solution Approach 2:
Multiple sensors provide continuous feedback on spray deposition quality, user position, and environmental factors to the controller, which automatically adjusts voltage to maintain consistent spray application. This feedback loop ensures reliable performance while keeping the user interface simple
3Productivity
If voltage is not actively adjusted during the spray pass, then the system is easier to control, but the spray attraction is not optimized for variables of the current session
Solution Approach 1:
The system dynamically adjusts voltage parameters in real-time during spray passes based on detected variables such as user stance position, environmental conditions, and spray deposition quality. This dynamic control optimizes spray attraction and deposition quality while the controller manages the complexity of coordination between multiple sensors and adjustment mechanisms
