Voice-Controlled Water Dispensing to Reduce Repeated Button Pressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current water dispensing apparatuses require users to repeatedly press buttons to dispense a desired amount of water, which is inconvenient and prone to errors, especially when filling large containers or selecting different temperatures.
Innovation Solution
A method utilizing voice recognition technology to control the water dispensing apparatus, allowing users to input desired amounts and temperatures through voice commands, eliminating the need for multiple button presses and ensuring accurate and safe water discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual button pressing is used to dispense water, then the apparatus can dispense water, but the user must repeatedly press buttons and continuously monitor water amount, increasing operation complexity and time consumption
Solution Approach 1:
The patent replaces manual button pressing (mechanical input) with voice recognition technology. The voice recognition module detects voice commands through acoustic waves and converts them into control signals, eliminating the need for repeated mechanical button presses. This allows users to input water dispensing requests naturally through speech, significantly reducing operation time and complexity.
2Productivity
If automatic water discharge button is used, then water discharge is automated, but the preset discharge amount is small and unrelated to container size, requiring multiple presses to fill large containers
Solution Approach 1:
The patent implements dynamic water dispensing control where the dispensing amount is not fixed but adapts based on real-time detection. The system dynamically adjusts the water dispensing duration and amount based on voice command interpretation and container detection results, allowing a single operation to dispense appropriate amounts for different container sizes rather than requiring multiple fixed-amount presses.
Solution Approach 2:
The system changes the water dispensing parameters (amount, duration, flow rate) based on detected conditions. When a large container is detected or when the system determines more water is needed, it automatically adjusts the dispensing parameters to provide larger amounts of water in fewer operations, rather than dispensing fixed small amounts repeatedly.
3Ease of operation
If voice recognition module operates continuously to enable voice commands, then user interaction is convenient, but power consumption increases
Solution Approach 1:
The voice recognition module operates periodically rather than continuously. The controller activates the voice recognition module only at specific intervals or when triggered by certain conditions (such as detecting a cup on the platform), allowing it to enter low-power states between activations. This periodic operation maintains voice command functionality while significantly reducing overall power consumption compared to continuous operation.

AI summary
The present invention relates to a water dispensing device control method, which includes: a step of allowing a call word in a sound shape uttered from a user to be input into a microphone; a step of identifying the input call word in a sound identifying module and outputting guiding sound of identifying the call word through a speaker; a step of allowing the desired discharge water amount in the sound shape uttered from the user to be input into the microphone; a step of identifying the input desired water discharge amount in the sound identifying module and outputting guiding sound of identifying the water discharge amount through the speaker; a step of allowing a user to input a water discharge order; a step of allowing water discharge to be implemented while a water discharge valve is opened; and a step of allowing the water discharge to be finished while the water discharge valve is closed when the water discharge flow rate detected in a flow rate sensor reaches the input desired water discharge amount.
