Solution Overview

Problem

Users risk mouth scald when consuming liquids through straws due to temperature inconsistencies, as existing methods rely on manual temperature judgment, which can be inaccurate, especially with insulating containers.

Innovation Solution

A liquid extraction control method and device that acquires real-time liquid temperature and controls a flow channel based on predetermined temperature ranges, preventing the liquid from flowing when outside safe temperatures, and optionally tracks cumulative flow values to manage liquid intake.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual temperature judgment is used for liquid extraction, then the operation is simple, but the temperature measurement precision is low leading to mouth scald risk

Engineering Contradiction:
Improvetemperature measurement precisionVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces manual temperature judgment (mechanical/sensory system) with an automated temperature detection system using sensors and control circuits. The temperature detection module continuously monitors liquid temperature and sends signals to the control module, which automatically opens or closes the flow channel based on predetermined safe temperature ranges, eliminating the need for manual temperature assessment.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a temperature detection module as an intermediary between the liquid and the user. This module acts as a mediator that safely measures the liquid temperature and communicates the information to the control system, allowing temperature monitoring without direct contact between the user's mouth and potentially hot liquid.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If real-time temperature monitoring and automated flow control are implemented, then safety is improved, but the device complexity increases

Engineering Contradiction:
ImprovesafetyVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a feedback control system where the temperature detection module continuously monitors liquid temperature and sends real-time data to the control module. The control module compares the detected temperature with predetermined safe ranges and automatically adjusts the flow channel state accordingly, creating a closed-loop feedback system that ensures safety while maintaining relatively simple device architecture.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs self-service by automatically monitoring temperature and controlling the flow channel without requiring user intervention. The control module autonomously decides when to open or close the flow channel based on temperature feedback, eliminating the need for manual temperature checking and flow control operations.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If flow channel is kept open for easy liquid extraction, then ease of operation is improved, but the risk of hot liquid entering mouth increases

Engineering Contradiction:
Improveease of liquid extractionVSAvoidmouth scald risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary action by pre-setting safe temperature ranges and having the temperature detection module continuously monitor liquid temperature before liquid extraction occurs. The control module proactively opens the flow channel only when temperature is within safe limits and closes it immediately when temperature exceeds safe ranges, preventing hot liquid from reaching the user's mouth before contact can occur.

Inventive Principle:
Principle #10Preliminary action

AI summary

A liquid extraction control method includes: acquiring a current temperature value of liquid to be extracted; determining whether the current temperature value is within a predetermined temperature value range; opening a liquid flow channel when the current temperature value is within the predetermined temperature range, and closing the liquid flow channel when the current temperature value is outside the predetermined temperature range. The temperature range of the liquid to be extracted can therefore be controlled, reducing probability of injuries caused by overly hot or cold liquid through a straw, and facilitating control of the temperature and extraction amount suitable for users, so as to achieve smart and quantitative fluid extraction.
