Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If waste plastic is incinerated or buried, then the disposal process is simple, but environmental pollution and resource waste occur
Solution Approach 1:
The patent converts waste plastic from a harmful substance into a useful resource by processing it into composite blocks mixed with inorganic materials. The organic polymer that would otherwise be incinerated or buried is transformed into a construction material component, eliminating pollution while creating valuable products.
Solution Approach 2:
The patent changes the physical and chemical parameters of waste plastic through mixing with inorganic materials (soil, sand, gravel) and applying heat treatment. This transformation changes the material properties from unusable waste to functional composite material suitable for construction applications.
2Productivity
If current recycling technology is used, then some waste plastic is recycled, but the recycling rate is low and economic feasibility is poor
Solution Approach 1:
The patent creates composite materials by combining processed waste plastic with inorganic materials such as soil, sand, and gravel. This composite approach increases the value and utility of recycled plastic, improving both recycling rates and economic feasibility by producing materials suitable for construction applications.
Solution Approach 2:
The patent divides the recycling process into distinct stages: organic material pretreatment, inorganic material pretreatment, mixing, and consolidation. This segmentation allows each process to be optimized independently while maintaining overall system efficiency and managing complexity.
3Reliability
If waste plastic is effectively mixed with inorganic soil, then recycling rate increases and pollution decreases, but the manufacturing process becomes more complex
Solution Approach 1:
The patent divides the manufacturing process into separate functional modules: organic material pretreatment part, inorganic material pretreatment part, mixing part, and consolidation part. Each module handles a specific task, making the overall complex process manageable and maintainable while achieving effective recycling.
Solution Approach 2:
The patent uses a mixing part as an intermediary between the pretreatment stages and the consolidation stage. This intermediary component combines the processed organic and inorganic materials in controlled proportions, ensuring effective mixing while maintaining process organization and manageability.
