Floor treatment system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor treatment systems lack operational safety due to potential pressure buildup and contamination risks in liquid containers during refilling, as well as inefficiencies in venting and preventing backflow through supply conductions.
Innovation Solution
A floor treatment system with a mobile apparatus and docking station featuring an opening device that automatically moves a wall portion of the liquid container into an open position when docked, allowing liquid to exit and preventing pressure buildup and contamination by ensuring the container opening is clear, and optionally using a valve for controlling the supply conduit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the container opening is sealed during refilling, then contamination is prevented, but pressure buildup occurs
Solution Approach 1:
The opening device is activated in advance during the docking process to open the container opening before refilling begins, preventing pressure buildup while maintaining contamination protection through the controlled opening mechanism
Solution Approach 2:
A valve mechanism serves as an intermediary component that controls the container opening state, allowing selective opening during refilling operations to balance contamination prevention with pressure release requirements
2Stress or pressure
If the container opening is opened during refilling, then pressure buildup is prevented, but contamination risk increases
Solution Approach 1:
The opening device activates the container opening in advance during the docking sequence, ensuring pressure can be equalized before liquid contact, while the controlled timing minimizes exposure to contamination
Solution Approach 2:
The valve acts as an intermediary that mediates between the need for pressure equalization and contamination prevention, providing controlled access that satisfies both requirements through timed operation
3Ease of operation
If a valve is added to control the supply conduit, then refilling control is improved, but device complexity increases
Solution Approach 1:
The valve is integrated into the existing docking station infrastructure to serve multiple functions including refilling control, pressure regulation, and contamination prevention, thereby minimizing the increase in overall device complexity while maximizing operational control
