Robotic Vacuum Docking Station With Mechanical Dirt Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robotic surface cleaning apparatuses require suction motors and air treatment members in docking stations to filter dirt, which complicates the design and functionality.
Innovation Solution
Incorporating a mechanical transfer member that conveys dirt from the robotic surface cleaning apparatus to the docking station, eliminating the need for suction motors and air treatment members in the docking station by moving dirt through the air treatment unit and into the docking station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If suction motors and air treatment members are installed in the docking station to filter dirt, then the dirt filtration function is improved, but the device complexity and cost increase
Solution Approach 1:
The patent extracts the air treatment function from the docking station and relocates it to the robotic vacuum cleaner. The air treatment unit with filtration capabilities is now integrated into the cleaner itself, allowing the docking station to be simplified to only provide charging and basic support functions. This resolves the contradiction by maintaining dirt filtration capability while eliminating the complexity of installing suction motors and air treatment members in the docking station.
2Productivity
If a mechanical transfer member is added to convey dirt to the docking station, then dirt transfer efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent merges the dirt conveyance function with the existing mechanical components of the robotic vacuum cleaner. The ram, originally designed for other purposes, is utilized to convey dirt from the air treatment unit to the dirt outlet. This integration approach improves dirt transfer efficiency without adding separate, complex mechanical transfer mechanisms, thereby resolving the contradiction between productivity and device complexity.
3Productivity
If the mechanical transfer member moves through the air treatment unit to convey dirt, then complete emptying of dirt storage chamber is achieved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent employs the existing structural features of the air treatment unit and dirt storage chamber to guide the mechanical transfer member's movement. The ram utilizes the available space and structural elements within the air treatment unit to convey dirt, rather than requiring precisely engineered dedicated guides or channels. This self-service approach allows complete emptying of the dirt storage chamber while minimizing the need for high manufacturing precision, resolving the contradiction between productivity and manufacturing precision requirements.
