Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual pump control is used for liquid dispensing, then the system is simple to operate, but the dosing precision deteriorates making calibrated dispensing difficult
Solution Approach 1:
The patent replaces the manual mechanical pump control system with an electronically actuated pump controlled by a microprocessor. The pump is actuated by electronic signals that precisely control the timing and duration of liquid dispensing, eliminating the imprecision of manual operation while maintaining ease of use through electronic interfaces.
Solution Approach 2:
The system incorporates a pressure sensor that detects when liquid reaches the dispensing point and sends feedback signals to the microprocessor. This feedback mechanism automatically stops the pump when the correct dose is delivered, ensuring precise dosing without requiring manual measurement or estimation by the operator.
2Productivity
If larger liquid tanks are used to reduce filling frequency, then the number of fillings is reduced, but the operator load and injury risk increase
Solution Approach 1:
The system uses a portable liquid container that can be dynamically exchanged or refilled without requiring the operator to carry excessive weight. The container design allows for efficient refilling procedures and includes features like ergonomic handles and balanced weight distribution to minimize operator strain during handling and movement.
Solution Approach 2:
The system incorporates automatic monitoring of liquid levels through pressure sensors and microprocessor control. When the liquid level is low, the system can automatically alert the operator or even initiate the refilling process, reducing the need for frequent manual interventions and minimizing the physical burden on operators.
3Productivity
If the pump generates over-pressure for liquid exit, then the liquid can be dispensed effectively, but liquid wastage occurs after treatment
Solution Approach 1:
The pressure sensor detects when liquid reaches the dispensing point and immediately sends a stop signal to the microprocessor, which cuts off the pump operation. This feedback mechanism ensures that liquid dispensing stops precisely when needed, preventing the continuous flow and over-pressure conditions that cause wastage in manual systems.
Solution Approach 2:
The electronic control system replaces the manual pump control that cannot quickly respond to stop dispensing. The electronically actuated pump can be precisely controlled to maintain over-pressure only during the exact dispensing window, then immediately release pressure to prevent drippage and wastage.
4Device complexity
If the nozzle is positioned in intermediate location on the tubular member, then the system structure is simplified, but correct treatment of some trap doors requires removing covers
Solution Approach 1:
The system uses an extendable tubular member with the nozzle that can be dynamically adjusted in length and position. The tubular member can be extended to reach deeper into trap doors or repositioned as needed, allowing the nozzle to be placed in the optimal position for each specific treatment scenario without requiring structural modifications or cover removal.
Solution Approach 2:
The dispensing system is segmented into modular components including the tubular member, nozzle, and positioning mechanisms that can be independently adjusted. This segmentation allows flexible configuration of the nozzle position relative to the tubular member, enabling access to various trap door types without compromising the simplified overall structure.
