Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional barrel-replacement type pump is used, then the grease barrel can be replaced, but residual grease remains in the barrel causing pollution and foreign matter insertion
Solution Approach 1:
The pump structure is segmented into multiple functional components including a suction chamber, pumping chamber, and discharge chamber separated by pistons and valves. This segmentation allows complete evacuation of grease from the suction chamber through controlled pumping action, preventing residual grease from remaining in the barrel
Solution Approach 2:
The pump performs preliminary cleaning action by completely discharging all grease from the barrel before replacement. The suction port is positioned at the bottom of the barrel and the pumping mechanism ensures all grease is extracted before the barrel is removed, preventing contamination from residual grease
2Adaptability or versatility
If a single discharge port pump is used, then the structure is simple, but it cannot provide variable grease discharge amounts for different equipment needs
Solution Approach 1:
The pump is designed with multiple discharge ports (first discharge port and second discharge port) that can selectively discharge grease at different rates. The control system can direct grease flow through different pathways to achieve variable discharge amounts, enabling the same pump to serve multiple equipment types with different grease requirements
Solution Approach 2:
The pump incorporates a controllable valve system that dynamically adjusts the discharge rate by switching between different discharge ports or opening/closing pathways. This dynamic control allows the pump to adapt its grease discharge characteristics in real-time based on equipment needs, transforming a static single-function device into a versatile multi-rate system
3Measurement precision
If a pump without flow control is used, then the structure is simple, but it cannot precisely control the grease flow amount for different lubrication requirements
Solution Approach 1:
The pump incorporates a flowmeter that continuously monitors the grease flow rate and provides feedback to the control system. Based on this feedback, the control system adjusts the valve positions or pumping parameters to maintain the desired flow rate, enabling precise control of grease discharge for different lubrication requirements
Solution Approach 2:
The pump replaces manual or mechanical flow control methods with an automated control system that uses sensors and electronic control. The flowmeter and controller work together to automatically regulate grease flow, substituting complex mechanical adjustment mechanisms with a more precise sensor-based control system

AI summary
One aspect of the present disclosure relates to a multipurpose grease barrel pump for preventing a presence of residual grease inside a grease barrel, which may easily adjust a discharge amount of grease, in which the multipurpose grease barrel pump is based on grease residue prevention type, has a branch and shock prevention structure, enables control (on/off) of a flow amount of the pump, and has a grease spray function, a function of periodically or continuously injecting a very small amount of the grease, and a typical pump function of discharging a large amount of the grease.
