Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid resin accelerator is used in cement compositions, then resin hardening is achieved, but mixing and handling complexity increases due to need for multiple mixers and equipment
Solution Approach 1:
The patent changes the physical state of the resin accelerator from liquid to solid form. This parameter change eliminates the need for separate liquid mixing equipment while maintaining the chemical function of accelerating resin hardening, thus resolving the contradiction between achieving reliable resin hardening and reducing mixing equipment complexity
Solution Approach 2:
The patent creates a composite material by combining solid resin accelerator particles with cementitious materials. This composite approach integrates the accelerator directly into the cement mix, eliminating the need for separate liquid resin mixing equipment and simplifying the overall mixing process while maintaining effective resin hardening
2Stability of the object's composition
If liquid resin components are mixed in batch mixers, then proper mixing is achieved, but processing time increases and bottlenecks occur
Solution Approach 1:
Changing the resin accelerator from liquid to solid form allows it to be incorporated directly into the cement slurry mixing process, eliminating the need for separate batch mixing of liquid resin components. This integration maintains proper mixing quality while significantly reducing processing time and eliminating bottlenecks in the cementing process
Solution Approach 2:
The solid resin accelerator is pre-incorporated into the cement slurry before the resin is added, ensuring proper distribution and mixing. This preliminary action eliminates the need for subsequent batch mixing operations, maintaining composition stability while accelerating the overall process
3Strength
If multiple liquid resin components are used, then desired mechanical properties are achieved, but material handling difficulty increases
Solution Approach 1:
The patent changes the physical state of the resin accelerator from liquid to solid, and further incorporates it into the cement slurry matrix. This simplifies material handling by reducing the number of separate liquid components that need to be handled and mixed, while the chemical composition is maintained to ensure desired mechanical properties of the cured resin are achieved
