Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fixed workshop type drying line is used to dry biomass fuel, then drying function is provided, but transportation cost is high and construction cost is high
Solution Approach 1:
The patent transforms the static fixed workshop drying line into a dynamic mobile vehicle platform. The drying equipment is mounted on vehicles that can move to different locations, allowing the drying function to be provided at various biomass fuel sources rather than requiring centralized fixed facilities. This reduces construction costs while maintaining drying capability.
Solution Approach 2:
The mobile vehicle platform integrates multiple functions including preprocessing, drying, and transportation in a single system. The vehicle serves as both the drying chamber and the transport means, eliminating the need for separate fixed workshop infrastructure and reducing overall construction costs.
2Ease of manufacture
If raw biomass fuel is transported to power plants for drying, then drying is performed, but transportation cost is high
Solution Approach 1:
Instead of transporting biomass fuel to fixed drying facilities, the patent inverts the approach by bringing the drying facility to the biomass fuel sources. The mobile vehicle platform travels to collecting points or farms, performs drying on-site, and then transports the dried fuel, thereby eliminating high transportation costs associated with moving wet biomass.
Solution Approach 2:
The mobile vehicle performs preprocessing and drying actions at the source before transportation. By cutting, dehydrating, and drying the biomass fuel at collecting points or farms rather than at the power plant, the system reduces transportation requirements and costs.
3Adaptability or versatility
If each power plant is provided with processing and drying line, then drying function is provided, but construction cost is high and power generation cost is high
Solution Approach 1:
The mobile vehicle platform can travel to serve multiple power plants and biomass sources, providing drying services dynamically rather than requiring each power plant to have its own fixed drying line. This shared mobile resource reduces overall construction costs while maintaining adaptability to serve different locations.
Solution Approach 2:
The mobile vehicle platform can be deployed to different locations as needed, discarding the need for permanent fixed infrastructure at each power plant. The same drying equipment serves multiple facilities sequentially, reducing total construction investment while maintaining service coverage.
