Water ejecting apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water purifiers face challenges such as limited mobility of the water ejection nozzle, risk of hot water splashes, contamination, and inconvenience in dispensing water at various heights, failing to provide a hygienic and user-friendly experience.
Innovation Solution
A water ejecting apparatus with a lifting motor that automatically moves the water ejection nozzle up and down, is rotatable and movable in both vertical and horizontal directions, and includes a touch bar for detecting container height, reducing water splash and enhancing hygiene by adjusting the nozzle height and minimizing contact load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the water ejection nozzle is fixed at a predetermined height, then the structure is simple and stable, but the user cannot place containers at various locations for water dispensing
Solution Approach 1:
The water ejection nozzle is transformed from a fixed structure to a dynamically adjustable one. The lifting cover moves vertically along the guide rail, and the rotator enables horizontal rotation, allowing the nozzle to adapt to different container positions and heights automatically
Solution Approach 2:
The nozzle positioning system adds vertical movement dimension through the lifting cover mechanism and horizontal rotation dimension through the rotator, transforming a single-position nozzle into a multi-dimensional adjustable nozzle that can serve various container placements
2Object-affected harmful factors
If the water ejection nozzle is positioned at a high location, then the structure is compact, but water splashes when dispensed water drops contact the cup below
Solution Approach 1:
The touch bar acts as a feedback mechanism that detects the presence and height of the container. When the container is detected, the system automatically adjusts the nozzle height to match the container position, preventing water splash while maintaining operational convenience
Solution Approach 2:
The system performs self-adjustment of the nozzle height based on automatic container detection. The lifting motor responds to touch bar signals and autonomously positions the nozzle at the appropriate height, eliminating the need for manual adjustment and preventing splash automatically
3Adaptability or versatility
If the water ejection nozzle is manually disassembled and reassembled to change position, then the nozzle can be repositioned, but user inconvenience occurs and components may be lost or damaged
Solution Approach 1:
The nozzle positioning system uses dynamic mechanical components (lifting cover, rotator, guide rail) that enable smooth, tool-free adjustment. Users can reposition the nozzle by simple operational inputs rather than disassembly, eliminating component loss risks and operational inconvenience
Solution Approach 2:
The manual disassembly-reassembly mechanical process is replaced with an automated motor-driven positioning system. The lifting motor and rotator mechanism substitute for manual handling, providing precise, repeatable, and safe nozzle repositioning without user intervention in mechanical assembly
4Adaptability or versatility
If the water ejection nozzle moves only in horizontal direction, then the mechanism is simple, but the nozzle cannot move in vertical direction limiting container placement options
Solution Approach 1:
The system merges two independent movement mechanisms: vertical lifting (lifting cover along guide rail) and horizontal rotation (rotator). These combined mechanisms work together to provide comprehensive multi-directional nozzle positioning capability while maintaining modular simplicity
Solution Approach 2:
The system adds the vertical dimension to the existing horizontal rotation capability. The lifting cover mechanism provides vertical movement along the guide rail, complementing the rotator's horizontal rotation to create a two-dimensional positioning system that greatly expands container placement options

AI summary
A water ejecting apparatus includes a case and a water ejection unit coupled to one side of the case. The water ejection unit includes a rotator seated inside at a front of the case, a first lifting cover coupled to one side of the rotator and allowing a lifting gear extending in an up-down direction to be fixed thereto, a second lifting cover movably accommodated inside the first lifting cover, a lifting motor coupled to the second lifting cover and configured to interwork with the lifting motor, and a water ejection nozzle installed at a lower end of the second lifting cover and configured to eject water. A water ejection pipe having one end connected to the water ejection nozzle and the other end extending to an inside of the case is disposed in a lower space of the lifting motor and the gear module.
