Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid dispensing systems often reuse discharging devices intended for single-use, leading to potential contamination and inefficiencies.
Innovation Solution
A liquid dispensing apparatus and system that includes a chemical liquid discharging device with a piezo jet method, where the use history of each device is tracked to prevent reuse by determining if the device has been previously used before discharging, ensuring single-use compliance and maintaining hygiene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the discharging device is designed for single-use to prevent contamination, then hygiene and reliability are improved, but device complexity increases due to tracking mechanisms
Solution Approach 1:
The patent implements a single-use discharging device that is discarded after one use to ensure hygiene and prevent contamination. The device includes a use history tracking mechanism that records whether the device has been used, and the controller prevents reuse by checking this history. This disposable approach with tracking ensures reliability while managing the complexity through automated monitoring.
Solution Approach 2:
The patent employs a feedback mechanism where the controller checks the use history of the discharging device before allowing operation. The use history information is read from storage, and based on this feedback, the controller either permits or prevents device operation. This feedback loop ensures that only unused devices can discharge liquid, maintaining hygiene standards.
2Productivity
If the discharging device is reused after single use, then productivity is improved, but contamination risk increases
Solution Approach 1:
The patent implements a single-use discharging device that is discarded after one use to ensure hygiene and prevent contamination. The device includes a use history tracking mechanism that records whether the device has been used, and the controller prevents reuse by checking this history. This disposable approach with tracking ensures reliability while managing the complexity through automated monitoring.
Solution Approach 2:
The patent applies preliminary anti-action by preventing the harmful effect of contamination before it can occur. The controller checks the use history before allowing device operation and blocks reuse of previously used devices. This preventive measure eliminates the possibility of contamination from reused devices while maintaining productivity through proper device management.
3Reliability
If use history tracking is implemented to prevent reuse, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent employs a feedback mechanism where the controller checks the use history of the discharging device before allowing operation. The use history information is read from storage, and based on this feedback, the controller either permits or prevents device operation. This feedback loop ensures that only unused devices can discharge liquid, maintaining hygiene standards.
Solution Approach 2:
The discharging device automatically tracks its own use history through integrated sensors and storage mechanisms. The device self-monitors whether it has been used and provides this information to the controller without requiring external tracking systems. This self-service approach maintains reliability while minimizing additional complexity.
