Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suction devices for patients with impaired mobility are inconvenient as they require manual operation, generate loud noise, and have high maintenance costs due to disposable catheters, and fail to provide continuous and efficient foreign material removal.
Innovation Solution
A suction device equipped with a sensor unit to detect abnormal breathing and foreign material in the bronchus, automatically inserting a catheter and adjusting suction pressure, featuring a mass flow meter sensor, stepping motor, and alternating cuffs to minimize patient discomfort and maintenance costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is required to remove foreign material, then the device can be operated, but convenience and work efficiency are reduced
Solution Approach 1:
The suction device automatically detects foreign material in the patient's body and performs suction operations without requiring manual intervention. The device monitors breathing conditions continuously and autonomously activates the suction mechanism when foreign material is detected, enabling the system to serve itself rather than requiring constant human operation.
Solution Approach 2:
The device incorporates sensors that continuously monitor breathing conditions and provide feedback to the control system. When the sensor detects changes indicating foreign material presence, the control unit processes this information and automatically activates the suction mechanism, creating a closed-loop feedback system that enables automatic operation based on real-time physiological data.
2Productivity
If suction device operates continuously to remove foreign material, then foreign material removal is efficient, but power consumption increases
Solution Approach 1:
Instead of continuous operation, the suction device operates periodically based on sensor detection. The system continuously monitors breathing conditions but only activates suction when foreign material is detected, creating an on-demand periodic operation pattern that maintains effectiveness while minimizing energy consumption during normal breathing conditions.
Solution Approach 2:
The device autonomously determines when suction is needed by monitoring its own operational environment through sensors. The system activates suction only when foreign material is detected and remains inactive during normal conditions, enabling self-regulated operation that optimizes the balance between productivity and energy consumption without requiring external control.
3Reliability
If catheter is replaced frequently due to contamination, then hygiene is maintained, but expenses increase
Solution Approach 1:
The suction device extracts and removes foreign material through the catheter without requiring the catheter itself to be replaced frequently. The system design allows the catheter to remain in place and be cleaned or sterilized between uses, separating the function of foreign material removal from the need for frequent catheter replacement, thereby reducing consumption and cost.
Solution Approach 2:
Instead of discarding the catheter after single use, the system recovers and reuses the catheter by sterilizing it between operations. The catheter is removed from the patient, cleaned and disinfected, then reused for subsequent suction operations, transforming a disposable item into a reusable component that maintains hygiene standards while reducing waste and cost.
