Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual oil dripping method is used, then device complexity is reduced, but manufacturing precision and measurement precision deteriorate
Solution Approach 1:
The patent replaces the manual mechanical dripping method with an automated system comprising a gas pump, throttle valve, and infrared detection module. The gas pump provides controlled positive pressure to drive oil dripping, the throttle valve precisely regulates gas flow to control dripping speed, and the infrared detection module automatically counts and records the number of drops, eliminating manual operation and achieving precise quantitative control.
Solution Approach 2:
The patent introduces a gas pump as an intermediary to provide controlled positive pressure, a throttle valve as an intermediary to regulate gas flow, and an infrared detection module as an intermediary to automatically detect and count drops. These intermediary devices mediate between the user's intent and the actual oil dripping process, enabling precise quantitative control without direct manual manipulation.
2Ease of operation
If manual oil dripping method is used, then operation simplicity is improved, but reliability deteriorates
Solution Approach 1:
The patent enables the system to automatically perform the dripping and counting functions through the gas pump, throttle valve, and infrared detection module. The system self-regulates the dripping process by controlling gas pressure and flow, and automatically counts drops using the infrared detection module, eliminating the need for manual operation while ensuring reliable quantitative control through automated feedback and recording.
3Productivity
If gas pump gas flow is increased, then productivity is improved, but manufacturing precision deteriorates
Solution Approach 1:
The patent employs a throttle valve to dynamically adjust the gas flow from the gas pump in real-time. The throttle valve can be opened or closed to different degrees, enabling precise control of the gas flow rate that drives the oil dripping. This dynamic adjustment capability allows the system to maintain optimal dripping speed for accurate drop counting while maximizing productivity, preventing both too-slow dripping that reduces efficiency and too-fast dripping that compromises precision.
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
The device enables accurate and efficient quantitative distribution of essential oils, allowing for precise control over the dripping process, reducing operator error and making it suitable for both professionals and non-professionals.
Implementation Method 1
the gas pump applies, through the gas inlet tube, pressure to the liquid level of the essential oil contained in the essential oil container. The essential oil is driven to be dripped from the oil outlet tube
Implementation Method 2
the drip number detection module includes a plurality of groups of infrared ray pair tubes which correspond to drip outlets of the N drip hole passages in position and are configured to detect essential oil drips

AI summary
A quantitative essential oil dripping device which includes: N sealed essential oil containers for containing essential oil, wherein N is a positive integer greater than or equal to 1; N gas inlet tubes and N oil outlet tubes, which are all inserted into the N essential oil containers respectively, wherein in each of the essential oil containers, a gas outlet of the gas inlet tube is located above an inlet of the oil outlet tube; a gas pump arranged at gas inlets of the N gas inlet tubes; a throttle valve communicating the gas pump with the essential oil container; and a drip number detection module configured to detect the drip number of the essential oil dripped from an oil outlet of the oil outlet tube. During use, the gas pump is started, pressure is applied to the essential oil container through the gas pump, and the essential oil is driven to be dripped from the oil outlet tube under the combined action of the gas pump and the throttle valve, thereby achieving the dripping of the essential oil. The drip number of the essential oil dripped from the oil outlet of the oil outlet tube is detected through the drip number detection module, and the amount of the dripped essential oil is measured by recording the drip number, thereby accurately controlling the dripping of the essential oil. After the dripping of the essential oil is completed, the gas pump is stopped.
