Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processes for producing lubricating greases are inflexible, leading to high storage costs and long waiting times due to the need for separate production batches for different quality greases, and they are difficult to control, resulting in challenges in maintaining specific specifications.
Innovation Solution
Adding a polymeric structure improver in a liquid composition at 25°C to a grease dispersion containing lubricating oil allows for the modification of grease properties, enabling the production of greases with improved water resistance, consistency, and homogeneity, while using commercially available components and existing industrial-scale plants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate production batches are used for different quality greases, then specific grease specifications can be produced, but storage costs and production time increase
Solution Approach 1:
The patent applies universality by developing a base grease composition that can serve multiple functions and be adapted to produce different grease specifications through additive packages. The base composition containing polymeric structure improvers can be modified with different additives to meet various customer requirements, eliminating the need for completely separate production batches for different grease types.
Solution Approach 2:
The patent applies preliminary action by pre-formulating a base grease composition with polymeric structure improvers that provides a consistent foundation. This base composition is prepared in advance and can then be quickly adjusted with different additive packages to produce various grease specifications, reducing the time required for separate batch productions.
2Manufacturing precision
If separate production batches are used for different quality greases, then specific grease specifications can be produced, but storage costs increase
Solution Approach 1:
The base grease composition serves as a universal platform that can be adapted to produce multiple grease specifications through additive variations. This reduces the need to store multiple different grease inventories, as a single base composition can be converted to different final products based on customer orders.
Solution Approach 2:
The patent enables a form of recovery by maintaining a base grease inventory that can be repurposed for different applications. Rather than discarding or storing separate batches of different grease types, the base composition with polymeric structure improvers can be recovered and adjusted to meet different specification requirements.
3Stability of the object's composition
If polymers are added during the structure formation phase at high temperatures, then grease structure is formed, but polymer degradation may occur
Solution Approach 1:
The patent applies parameter changes by carefully controlling the addition temperature and timing of polymeric structure improvers. The polymers are added at specific temperatures during the structure formation phase to ensure proper grease structure development while maintaining polymer stability. The process parameters are optimized to balance structure formation with polymer integrity.
Solution Approach 2:
The patent applies preliminary action by pre-selecting polymers with appropriate thermal stability characteristics before the structure formation phase. The polymeric structure improvers are chosen and prepared in advance to withstand the temperatures required for grease structure formation without degrading, ensuring both structure development and polymer reliability.
Applied Scientific Principles

Function Achieved in This Case
This approach allows for the production of greases with enhanced water resistance and consistency, enabling flexible production to meet customer demands without significant changes in consistency, reducing storage costs and production time, and improving physical parameters like water resistance.
Implementation Method 1
The production of greases is a consequence of physicochemical processes, with the aid of which the lubricating grease structure is constructed from thickener molecules generated in situ.
Implementation Method 2
In the course of this, different processes proceed, for example the aggregation of the thickener crystals generated in phase 1
Implementation Method 3
In a mechanical phase, additives, solid lubricants and the like, and also setting oil for fine adjustment of the end consistency, are added.
