Rack-and-Pinion Water Nozzle Extension for Large Container Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water purifiers have a fixed water ejection unit that limits user convenience, as it cannot be easily adjusted to accommodate containers of various sizes and shapes, and the fixed position restricts the ejection of water into containers with larger inlets, leading to difficulties in water dispensing and reduced user convenience.
Innovation Solution
A water ejecting apparatus with a movable water ejection nozzle that can be rotated and moved horizontally, allowing adjustment of the interval between the nozzle and the case, using a gear module and driving motor to facilitate movement and prevent shaking, and equipped with sensors for precise control and user input for optimal positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the water ejection unit is fixed to the front surface of the water purifier main body, then the structure is simple and stable, but the user convenience is reduced and it is difficult to accommodate containers of various sizes and shapes
Solution Approach 1:
The water ejection unit is transformed from a fixed structure to a movable one, capable of rotating and extending horizontally. The rotating module allows the nozzle to rotate between 0-180 degrees, while the extending module enables horizontal movement, providing dynamic adjustment to accommodate different container sizes and positions.
Solution Approach 2:
The water ejection unit is divided into separate functional modules: a rotating module for angular adjustment and an extending module for horizontal movement. This segmentation allows independent control of each degree of freedom, enabling precise positioning while maintaining structural clarity.
2Adaptability or versatility
If the water ejection unit is separated from the main body and rotated by the user, then the position can be changed to a required position, but the length in the front and rear direction is fixed, making it difficult to receive water in containers having a large inlet size
Solution Approach 1:
The water ejection unit is transformed from a fixed structure to a movable one, capable of rotating and extending horizontally. The rotating module allows the nozzle to rotate between 0-180 degrees, while the extending module enables horizontal movement, providing dynamic adjustment to accommodate different container sizes and positions.
Solution Approach 2:
The water ejection unit gains an additional degree of freedom by adding horizontal extending capability to the existing rotating functionality. This transforms the adjustment from a single rotational dimension to a two-dimensional movement space, enabling the nozzle to reach various positions and angles for different container configurations.
3Adaptability or versatility
If the water ejection nozzle is moved horizontally using a driving motor and gear module, then the interval between the case and the water ejection nozzle can be adjusted, but shaking may occur during movement
Solution Approach 1:
A sensor is integrated into the system to detect the position of the water ejection nozzle during horizontal movement. This feedback mechanism allows the control system to monitor the movement process and make real-time adjustments to maintain stability and prevent shaking, ensuring reliable operation.
