Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the power of the power washer is increased, then the cleaning capability is improved, but the footprint and size of the device increases
Solution Approach 1:
The patent reconfigures the internal arrangement of components by changing their spatial orientation from conventional layouts to a compact configuration where the battery, motor, and pump are closely integrated in a three-dimensional space, allowing increased power density without increasing the device's footprint
Solution Approach 2:
The patent merges the battery, motor, and pump into a tightly integrated assembly where components are positioned immediately adjacent to each other, reducing overall device size while maintaining the power required for effective cleaning operations
2Duration of action of moving object
If the battery size is increased to provide sufficient power and endurance, then the runtime is improved, but the device footprint increases
Solution Approach 1:
The patent optimizes the battery configuration by arranging cells in series to achieve the required voltage for extended runtime while maintaining a compact physical footprint through efficient three-dimensional space utilization
3Area of stationary object
If the footprint is reduced to improve storage and shipping efficiency, then manufacturing and shipping costs are reduced, but the available space for power components is limited
Solution Approach 1:
The patent employs a nested arrangement where the motor is positioned within the battery housing space, and the pump is integrated adjacent to the motor, creating a compact nested configuration that maximizes power density within a reduced footprint
Solution Approach 2:
The patent utilizes parallel axis alignment of the battery, motor, and pump components to optimize spatial arrangement, allowing efficient packing of power components in a compact configuration that maintains sufficient power output
