Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If bitumen is transported through pipelines, then transport capacity is increased, but diluents must be added which increases cost and reduces bitumen quantity
Solution Approach 1:
The patent changes the physical state parameter of bitumen from liquid to solid form (aggregates), eliminating the need for diluents to achieve sufficient fluidity for pipeline transport. This allows 100% bitumen content without diluent addition, resolving the contradiction between transport capacity and bitumen quantity.
Solution Approach 2:
The patent creates composite solid aggregates consisting of bitumen combined with solidifying agents or binders. These composite structures maintain bitumen's transportability through pipelines while preserving pure bitumen content, eliminating the need to trade bitumen quantity for transport capability.
2Adaptability or versatility
If bitumen is transported by truck, then flexibility is improved, but efficiency and cost performance deteriorate for large quantities over large distances
Solution Approach 1:
The solid bitumen aggregates can be transported through multiple modes including pipelines, rail, and trucks, making the transport system universal. The solid form enables efficient large-volume transport through pipelines while maintaining flexibility to use alternative modes when needed, resolving the contradiction between flexibility and efficiency.
3Adaptability or versatility
If diluent recovery units are installed at intermediate points, then bitumen handling capability is improved, but installation cost increases
Solution Approach 1:
The patent extracts and eliminates the need for diluent recovery units by transporting bitumen in solid form that does not require diluents. This removes the complex infrastructure of DRUs from the system, reducing installation costs while maintaining bitumen handling capability.
4Ease of operation
If solid bitumen pellets are used, then handling and storage safety is improved, but pellet strength under compression must be sufficient to prevent failure
Solution Approach 1:
The patent optimizes the physical parameters of solid bitumen aggregates, including size, density, and internal structure, to achieve sufficient crush resistance. The solid form provides inherent structural integrity that prevents pellet failure during handling and storage while maintaining safety benefits.
