Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robot swimming pool cleaners have limited space utilization due to the occupation of engine and battery compartments, resulting in insufficient garbage loading capacity and frequent cleaning needs.
Innovation Solution
The design includes a sealed compartment with a motor and output gear integrated with the first driving wheel, allowing the motor compartment to be positioned at one end and increasing the space for the garbage bin, along with a gear system for efficient movement and four-wheel drive capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the engine compartment and battery compartment occupy most of the space in the robot cleaner, then the robot can function properly, but the garbage bin has insufficient loading capacity
Solution Approach 1:
The patent merges the motor with the driving wheel structure, integrating the motor compartment into the wheel hub. This allows the motor to share space with the driving mechanism, effectively reducing the space occupied by separate engine and battery compartments, and thereby increasing the garbage bin capacity.
Solution Approach 2:
The patent implements a nested structure where the motor is positioned within the driving wheel assembly. The motor compartment is nested within the overall wheel structure, allowing efficient use of internal space and maximizing the volume available for the garbage bin.
2Volume of stationary object
If the motor compartment is positioned centrally, then the structure is balanced, but the garbage bin space is reduced
Solution Approach 1:
The patent adopts an asymmetric layout where the motor compartment is positioned off-center within the driving wheel assembly rather than in the center of the robot body. This asymmetric positioning allows the garbage bin to occupy the central and rear portions of the robot, maximizing its volume while the motor's position is optimized for mechanical efficiency within the wheel structure.
3Ease of manufacture
If separate compartments are used for motor and driving mechanism, then maintenance is easier, but space efficiency decreases
Solution Approach 1:
The patent combines the motor compartment with the driving wheel structure, creating an integrated assembly. The motor is housed within the wheel hub, merging what would traditionally be separate compartments. This integration maximizes space efficiency and garbage capacity while the wheel itself can be designed as a removable module for maintenance purposes.
