Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual sensors and components are sold separately and require user wiring, then system customization is improved, but installation complexity and user burden increase
Solution Approach 1:
The patent combines multiple separate components (reservoir, pump, sensors, wiring, filters) into a single pre-assembled lubrication system unit. This integration maintains the adaptability of having individual functional elements while eliminating the complexity of user wiring and assembly, as the entire system is pre-configured and ready for installation as one package.
2Volume of stationary object
If reservoir capacity is reduced to fit standard packages, then system compactness is improved, but refilling frequency increases
Solution Approach 1:
The system employs a dynamically adjustable reservoir capacity that can be configured based on specific application requirements. The reservoir is designed to accept various容量的 lubricant containers, allowing the system to adapt between compact configurations for space-constrained applications and larger capacities for reduced refilling frequency, thus balancing system size against operational continuity needs.
3Device complexity
If lubricant is fed directly from reservoir to multiple pump inlets, then system simplicity is improved, but uneven lubricant distribution and cavitation occur
Solution Approach 1:
The patent introduces a manifold as an intermediary component between the reservoir and the multiple pump inlets. This manifold serves as a distribution hub that receives lubricant from the reservoir and evenly distributes it to all pump inlets through dedicated passages, ensuring uniform lubricant availability to each plunger packing while maintaining relatively simple system architecture.
4Device complexity
If reservoirs do not provide contamination-free lubricant, then system simplicity is maintained, but pump packing lubrication quality deteriorates
Solution Approach 1:
The system incorporates filtration mechanisms that perform preliminary cleaning of the lubricant before it reaches the pump packings. Filters are positioned in the lubricant path to remove contaminants in advance, ensuring that only clean lubricant contacts the pump components, thereby protecting against wear and maintaining lubrication quality without significantly complicating the overall system design.
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 system provides reliable, contamination-free lubrication with reduced refilling frequency, prevents cavitation, and minimizes equipment downtime through easy installation and monitoring.
Implementation Method 1
A first filter for removing contaminants from the lubricant prior to the lubricant entering the large capacity reservoir
Implementation Method 2
A second filter can be provided for filtering lubricant leaving the reservoir and entering the manifold

AI summary
A lubricator package for intermittently delivering a lubricant to lubrication points on packing on a high-pressure reciprocating pump, a frac pump is described. A preferred package includes a large (e.g., 10 gallon) capacity reservoir; a three or five outlet pump; a common manifold receiving oil from the large capacity reservoir and supplying oil or grease to the pumps; a mounting stand supporting the large capacity reservoir and the five outlet pump; and an optional a control package providing low level monitoring of lubricant flow and controlling the pump providing a pump stroke counter or timer.
