Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the system measures all fluid flow through the tube, then the volume measurement is comprehensive, but the measurement precision deteriorates because air intake is incorrectly counted as water intake
Solution Approach 1:
The patent introduces a liquid sensing module as an intermediary component between the flow measurement system and the air/water differentiation task. This sensor acts as a mediator that detects the presence of liquid in the tube and provides signal information to distinguish water intake from air intake, thereby resolving the measurement accuracy problem without compromising comprehensive fluid monitoring
Solution Approach 2:
The patent replaces the purely mechanical flow measurement approach with an integrated sensing system that combines liquid detection (via capacitive or optical sensing modules) with flow measurement. This substitution enables the system to differentiate between liquid and gas phases, improving measurement precision while maintaining comprehensive volume tracking
2Productivity
If the system continuously monitors fluid flow, then the hydration tracking is comprehensive, but the calculation accuracy deteriorates due to air intake being counted as water
Solution Approach 1:
The liquid sensing module serves as an intermediary that provides phase identification information to the processing module. This mediator enables the system to maintain continuous monitoring productivity while filtering out false readings from air intake, thus preserving calculation accuracy
Solution Approach 2:
The system implements feedback through the liquid sensing module that continuously provides information about the presence or absence of liquid in the tube. This feedback mechanism allows the processing module to adjust calculations in real-time, ensuring accurate water intake measurement while maintaining comprehensive hydration tracking
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Accurately measures and displays daily water intake, providing users with precise hydration management.
Implementation Method 1
the liquid sensing module 34 is a non-contact liquid level sensor such as capacitive touch integrated circuit (IC)
Implementation Method 2
When the users drink water from containers such as cups through straws... the flowing of the liquid drives the fan blade 21 in the flow guide chamber 13 to rotate
Implementation Method 3
a flow sensing module 33... which is connected with and used for sensing the metal or magnet 23 mounted in the fan blade 21

AI summary
A liquid beverage flow meter having a flow guide chamber and a mounting chamber in a main body is provided. An upper end and a lower end of the main body are provided with a tube while a liquid sensing module is disposed adjacent to the tube. A fan blade mounted in the flow guide chamber is connected with and sensed by a flow sensing module. Thereby a processing module is driven by the liquid sensing module to calculate total rotation times of the fan blade from the flow sensing module and convert the rotation times into liquid flow to be displayed on a display module once the liquid sensing module detects liquid flowing through the tube while users drink the liquid. If no liquid flow is detected, the processing module will not be driven to operate. Thereby water intake volume is calculated more accurately.
