Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water purifiers face challenges with inconvenient water ejection mechanisms, limited positional flexibility, risk of hot water splashes, contamination, and inadequate detection of container height, leading to user inconvenience and safety issues.
Innovation Solution
A water ejecting apparatus with a lifting motor that automatically moves the water ejection nozzle up and down, is rotatable in both vertical and horizontal directions, and includes a touch bar for sensitive container height detection, minimizing pipe deformation and reducing splash risk through adjustable nozzle height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the water ejection nozzle is fixed at a high position, then the water purifier structure is simple, but water splashes when dispensed into containers causing contamination and burn risks
Solution Approach 1:
The water ejection nozzle is made dynamically adjustable in height through a lifting mechanism driven by a motor. The nozzle can move vertically along a guide rail between a first position (higher) and a second position (lower), allowing the system to adapt to different container heights and prevent water splash while maintaining structural simplicity.
Solution Approach 2:
A sensor detects the presence and height of the container, providing feedback to the control unit. The control unit then automatically adjusts the nozzle height to the appropriate position, enabling closed-loop control that prevents water splash without requiring complex manual positioning mechanisms.
2Object-affected harmful factors
If the water ejection nozzle is positioned low for all containers, then water splash is prevented, but the positioning mechanism becomes overly complex to accommodate varying container heights
Solution Approach 1:
Instead of providing multiple fixed positions or complex adjustable mechanisms, the system uses a single motor-driven lifting mechanism that can dynamically position the nozzle at any height within the range between the first and second positions, simplifying the overall structure while maintaining flexibility.
Solution Approach 2:
The system changes the height parameter of the nozzle dynamically based on container detection. The motor adjusts the nozzle position to match the container height, allowing the system to adapt to varying container sizes without requiring complex mechanical structures for each possible height.
3Adaptability or versatility
If the water ejection nozzle is manually adjusted to different positions, then positional flexibility is achieved, but user inconvenience and potential water leakage occur during adjustment
Solution Approach 1:
The system performs automatic self-adjustment of the nozzle position based on sensor detection of the container. The motor automatically moves the nozzle to the appropriate height without requiring user intervention, eliminating the inconvenience and potential leakage risks associated with manual adjustment while maintaining full positional flexibility.
Solution Approach 2:
The sensor continuously monitors the container presence and height, providing feedback to the control unit which automatically adjusts the nozzle position. This closed-loop system eliminates the need for manual user adjustment while providing adaptability to various container types and heights.
4Adaptability or versatility
If the water ejection nozzle moves vertically, then container height detection becomes necessary, but the detection system becomes more complex
Solution Approach 1:
A sensor is positioned to detect the container when the nozzle is at the second (lower) position. The sensor provides feedback to the control unit, which then determines the appropriate nozzle height. This simple detection system works effectively in conjunction with the motor-driven lifting mechanism to achieve container height adaptation without requiring complex detection hardware.
Solution Approach 2:
The sensor acts as an intermediary between the physical container and the control system. It detects the container's presence and provides electrical signals to the control unit, which then translates this information into appropriate motor control commands for nozzle positioning, simplifying the overall detection system.
