Solution Overview
Problem
Conventional water purifiers suffer from water splashing issues due to the fixed height of the water discharge nozzle, which can lead to inefficiency and mess, especially when using glasses of varying sizes, and the movable water discharge nozzle tends to randomly descend due to its self-weight, making it difficult to maintain a desired height.
Innovation Solution
The water purifier incorporates a movable water discharge module with a resistance unit and guide parts to adjust the nozzle's height, preventing splashing and ensuring the nozzle remains at the desired position, featuring a stainless steel nozzle and a tray that rotates for improved user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the water discharge nozzle is made movable to adjust height, then water splashing is prevented and adaptability is improved, but the nozzle tends to randomly descend due to self-weight
Solution Approach 1:
The patent applies a resistance unit that generates upward resistance force to counteract the downward gravitational force on the movable water discharge nozzle. This resistance unit includes a resistance member and a spring that work together to provide the necessary counterbalancing force, preventing the nozzle from randomly descending while maintaining height adjustability.
Solution Approach 2:
The patent implements a feedback mechanism where the resistance unit continuously monitors and responds to the position of the movable water discharge nozzle. The spring-based resistance unit automatically adjusts the counterbalancing force based on the nozzle's position, providing stable equilibrium at any selected height without requiring active control systems.
2Adaptability or versatility
If the water discharge nozzle is made movable, then adaptability is improved, but the device complexity increases due to additional components
Solution Approach 1:
The patent divides the water discharge system into a fixed case and a movable case, allowing the nozzle to be segmented into adjustable portions. The resistance unit is further segmented into a resistance member and a spring, enabling independent optimization of each component's function while reducing overall system complexity.
Solution Approach 2:
The patent introduces a guide part as an intermediary component between the movable water discharge nozzle and the fixed case. This guide part provides smooth guidance and support during movement, simplifying the connection mechanism while ensuring stable operation and reducing the complexity of direct attachment methods.
3Reliability
If a resistance unit is added to prevent nozzle descent, then position stability is improved, but friction increases reducing operational sensitivity
Solution Approach 1:
The patent applies different friction characteristics to different parts of the resistance unit. The guide part provides low-friction guidance for smooth operation, while the resistance member and spring provide higher friction for stable position holding. This localized differentiation of friction properties enables both ease of operation and position stability.
Solution Approach 2:
The patent utilizes the elastic properties of the spring in the resistance unit to dynamically adjust the resistance force based on the nozzle's position. The spring constant and compression distance are optimized to provide minimal resistance during movement (improving operational sensitivity) while maintaining sufficient resistance to prevent random descent (ensuring position stability).
