Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual sputum clearance is performed by experienced personnel, then sputum clearance accuracy is improved, but labor intensity increases and operational complexity increases
Solution Approach 1:
The system enables self-service sputum clearance by automatically detecting sputum locations through sound receivers and controlling percussion units without requiring experienced manual operators. The control unit autonomously processes sound signals and triggers percussion at identified sputum regions, eliminating the need for skilled personnel to manually identify and treat sputum accumulation areas.
Solution Approach 2:
The patent replaces the mechanical manual percussion system with an automated electromechanical system. Sound receivers detect sputum locations, and control units automatically activate percussion units at the correct positions and angles, substituting the experienced human operator's manual actions with an automated detection-and-actuation system that maintains accuracy while reducing labor intensity.
2Productivity
If manual sputum clearance is performed, then sputum removal is achieved, but time consumption increases and productivity decreases
Solution Approach 1:
The system performs preliminary detection of sputum locations using sound receivers before initiating percussion treatment. By pre-identifying all sputum accumulation regions through acoustic signal analysis, the system can then efficiently target each location without time-consuming manual assessment, thereby reducing overall treatment time while maintaining thoroughness.
Solution Approach 2:
The automated system enables continuous monitoring and treatment of sputum accumulation. The control unit continuously processes sound signals and can immediately activate percussion units when sputum is detected, eliminating interruptions and delays associated with manual assessment. This continuous operation increases productivity by maintaining constant therapeutic action without idle time between detection and treatment.
3Area of stationary object
If multiple percussion units are used, then sputum clearance coverage is improved, but device complexity increases
Solution Approach 1:
The system divides the sputum clearance function into multiple independent percussion units, each capable of operating autonomously under control unit direction. This segmentation allows simultaneous treatment of multiple sputum locations across different body regions, expanding coverage while keeping each individual unit relatively simple in structure.
Solution Approach 2:
Multiple percussion units share common control and detection systems, creating a multi-functional integrated apparatus. The control unit can direct any percussion unit to any required location and angle, making each unit universally applicable to various sputum positions. This shared infrastructure reduces overall device complexity compared to having separate independent systems for each treatment location.
