Water Ejection Nozzle with Lifting Motor and Touch Bar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water purifiers face challenges with user convenience, as their fixed water ejection nozzles limit placement options, cause water leakage during assembly/disassembly, and fail to detect container heights, leading to splashing and contamination 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 to detect container height and size, minimizing pipe deformation and reducing splashing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the water ejection nozzle is fixed in position, then the structure is simple and reliable, but the user convenience deteriorates due to limited container placement options
Solution Approach 1:
The water ejection nozzle is transformed from a fixed structure to a movable one, capable of adjusting its position in vertical and horizontal directions. The lifting cover moves vertically to adjust nozzle height, while the rotator enables horizontal rotation, allowing the nozzle to dynamically adapt to different container positions and sizes.
Solution Approach 2:
The system incorporates a touch bar that automatically detects the presence and height of containers. When a container is detected, the lifting motor automatically adjusts the nozzle height to match the container, eliminating the need for manual positioning by the user.
2Object-affected harmful factors
If the water ejection nozzle is positioned at a fixed height, then the device structure is simple, but water splashing and contamination occur due to inability to adapt to different container heights
Solution Approach 1:
The touch bar serves as a feedback mechanism that detects container height and position. This information is transmitted to the control system, which then commands the lifting motor to adjust the nozzle height accordingly, creating a closed-loop control system that prevents water splashing by ensuring proper nozzle-to-container alignment.
Solution Approach 2:
The system performs preliminary detection of container height and position before water ejection begins. The lifting motor pre-adjusts the nozzle to the appropriate height based on touch bar detection, ensuring that when water is ejected, the nozzle is already positioned to prevent splashing and contamination.
3Ease of operation
If the water ejection nozzle requires manual disassembly and reassembly to change position, then the structure is simple, but user convenience deteriorates and components may be lost or damaged
Solution Approach 1:
The manual mechanical assembly/disassembly process is replaced with an automated electromechanical system. The lifting motor and rotator enable electronic control of nozzle position, replacing the need for manual screw tightening and component handling, thereby improving ease of operation while containing complexity within the automated mechanism.
4Adaptability or versatility
If the water ejection nozzle can only move horizontally, then the mechanism is simple, but adaptability deteriorates due to inability to adjust vertical position
Solution Approach 1:
The nozzle positioning system is extended from one-dimensional horizontal movement to two-dimensional movement by adding vertical lifting capability. The lifting cover and lifting motor provide vertical adjustment, while the rotator maintains horizontal rotation capability, enabling the nozzle to adapt to containers at various heights and positions.
