Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water purifiers require user intervention to extract water, leading to potential splashing and inconvenience, and there is a need for a system that can accurately and stably supply fluid to a container without user operation once positioned.
Innovation Solution
An automatic extraction device equipped with a displacement measuring unit, control unit, and water extraction cock that detects the presence and stability of a container within a preset distance range, outputs signals to control fluid supply, and stops supply upon movement to prevent splashing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic extraction is implemented without user operation, then user convenience is improved, but container positioning accuracy and stability cannot be ensured
Solution Approach 1:
The displacement measuring unit performs preliminary detection to determine whether a container is present at the water extraction point before automatic extraction begins. This preliminary action ensures that the system only activates when proper container positioning is confirmed, resolving the contradiction by establishing positioning accuracy as a prerequisite for automatic operation.
Solution Approach 2:
The control unit continuously monitors the displacement measurement data and compares it against threshold values to determine container stability. This feedback mechanism ensures that automatic extraction only proceeds when both positioning accuracy and stability are confirmed, allowing the system to maintain ease of operation while ensuring precise container positioning.
2Productivity
If fluid supply continues without monitoring container stability, then productivity is improved, but water splashing and residual water problems occur
Solution Approach 1:
The control unit continuously monitors displacement measurement data during fluid supply to detect any container movement. When movement is detected, the system immediately stops fluid supply, preventing water splashing and residual water problems. This feedback-based monitoring allows the system to maintain high productivity while eliminating harmful effects.
Solution Approach 2:
The system takes preliminary anti-action by stopping fluid supply before water splashing can occur. By monitoring container stability in real-time and preemptively stopping supply when movement is detected, the system prevents the harmful effect of water splashing rather than addressing it after it occurs.
3Measurement precision
If displacement measurement is performed continuously, then container stability detection is improved, but energy consumption increases
Solution Approach 1:
The displacement measuring unit performs measurements at periodic intervals rather than continuously, determining container stability by comparing displacement values at different time points. This periodic measurement approach maintains accurate container stability detection while significantly reducing energy consumption compared to continuous monitoring.
