Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional pneumatic control is used to dispense, then automatic dispensing operations can be carried out quickly, but the air pressure control becomes uneven leading to inconsistent dispensing amount
Solution Approach 1:
The system incorporates a pressure sensor that continuously monitors the air pressure in the dispensing cartridge and provides feedback to the control unit. When the pressure drops below a threshold value, the control unit automatically activates the electromagnetic valve to replenish gas, ensuring consistent pressure and dispensing amount throughout the operation
Solution Approach 2:
The system performs automatic pressure compensation without manual intervention. The control unit autonomously detects pressure drops and triggers the electromagnetic valve to replenish gas, enabling the system to self-regulate and maintain consistent dispensing performance throughout the operation
2Reliability
If manual pressure adjustment is performed when gas pressure drops, then normal operation can be restored, but the response time is long and dispensing amount remains inconsistent
Solution Approach 1:
The pressure sensor continuously monitors gas pressure in real-time and provides immediate feedback to the control unit. When pressure drops below the threshold, the system automatically activates the electromagnetic valve to replenish gas, eliminating the time delay associated with manual pressure adjustment and ensuring continuous reliable operation
Solution Approach 2:
The system replaces manual mechanical pressure adjustment with an automated electronic control system. The control unit with electromagnetic valve automatically replenishes gas when pressure drops, substituting the slow manual adjustment process with a fast automated response that maintains operation continuity
3Manufacturing precision
If the signal propagation path is made longer to detect liquid level variation, then liquid output control precision is improved, but the response time for regulating pressure becomes longer
Solution Approach 1:
The system replaces the conventional mechanical signal propagation path with an electronic sensing and control system. The pressure sensor and control unit provide immediate electronic detection and response to pressure changes, achieving both high precision liquid output control and fast pressure regulation response simultaneously
Solution Approach 2:
The system introduces a pressure sensor as an intermediary that directly monitors gas pressure and provides immediate feedback to the control unit. This intermediary enables rapid detection and response to pressure changes without the delays associated with longer mechanical signal paths, maintaining both precision and speed

AI summary
A fast glue replenishment device by using a dispensing cartridge is illustrated, which has a power unit, a regulation unit, a gas container, a control unit and a dispensing cartridge. The regulation unit controls a gas pressure of a gas output by the power unit to be equal to a necessary gas pressure value which the dispensing cartridge pushes a supply material for dispensing. When the dispensing cartridge pushes the supply material for dispensing, the gas container continuously provides the gas having the gas pressure value into the dispensing cartridge by using the control unit, such that the dispensing cartridge is maintained to have the necessary gas pressure value which the dispensing cartridge pushes the supply material for dispensing. Thus, the supply material is pushed in a short path and in a time differential to increase accuracy of pushing the supply material for dispensing.
