Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If self-propelled street sweeping equipment is mounted on a truck chassis, then the equipment has sufficient power and cleaning capability, but the equipment becomes excessively large and expensive
Solution Approach 1:
The patent divides the street sweeping equipment into separate functional modules: a self-propelled unit with combustion or electric motor for mobility, and a separate suction unit with turbine for cleaning. This segmentation allows each module to be optimized independently, reducing the overall size and cost while maintaining sufficient cleaning capability through the dedicated turbine-powered suction system.
Solution Approach 2:
The self-propelled unit is designed to perform multiple functions: it provides propulsion for the entire system, carries the operator in a protected cabin, and houses the hydraulic system for controlling sweeping and suction operations. This multi-functionality reduces the need for separate truck-mounted systems, decreasing overall equipment size and cost.
2Ease of manufacture
If self-propelled street sweeping equipment is made smaller and less complex, then the equipment cost is reduced, but the equipment lacks safety and comfort features like closed cabins and fairing assemblies
Solution Approach 1:
The patent employs a dynamic hydraulic system that can independently control the operation of sweeping brushes and suction turbine based on real-time conditions. This allows the smaller, more cost-effective equipment to maintain safety and performance by adaptively adjusting operational parameters, compensating for the reduced physical size through intelligent control.
Solution Approach 2:
The patent introduces a hydraulic system as an intermediary between the self-propelled unit and the suction unit, enabling coordinated operation of multiple functions from a single operator position. This intermediary system allows the compact equipment to achieve the safety and operational control typically associated with larger truck-mounted systems.
3Device complexity
If the equipment operates without air filtration, then the equipment is simpler and less expensive, but the equipment expels dust and residues back into the environment
Solution Approach 1:
The patent extracts the air filtration function as a separate, integrated component within the suction system. The turbine-driven suction unit incorporates filters that capture dust and residues from the air before expulsion, removing the harmful function from the system while maintaining overall simplicity through the modular design where filtration is built into the existing suction pathway rather than adding a separate complex filtration system.
