Suction foot for a floor cleaning machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction cups in floor cleaning machines require time-consuming and inconvenient cleaning due to dirt accumulation, which dries into a solid layer, hindering efficient operation.
Innovation Solution
A suction base with a flushing device that supplies rinsing fluid into the suction channel, connected to the suction foot base and suction channel, allowing for easy cleaning by using the suction device to remove the fluid and dirt, with optional features like hose couplings, multiple flushing fluid openings, and a hollow body design for improved cleaning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the suction channel is used continuously for floor cleaning, then cleaning productivity is improved, but dirt accumulates in the suction channel requiring time-consuming cleaning interruptions
Solution Approach 1:
The invention applies preliminary action by introducing flushing fluid into the suction channel before dirt can accumulate to problematic levels. The flushing device enables proactive cleaning during operation, preventing dirt buildup rather than requiring reactive cleaning interruptions. This allows the suction channel to be maintained in a clean state continuously, eliminating productivity losses from cleaning stops.
2Reliability
If the suction channel is cleaned frequently to prevent dirt accumulation, then cleaning effectiveness is maintained, but operational time is reduced due to cleaning interruptions
Solution Approach 1:
The invention enables continuity of useful action by allowing the suction channel to be flushed with cleaning fluid during normal operation without stopping the floor cleaning process. The flushing can occur continuously or at regular intervals while the machine remains operational, maintaining cleaning effectiveness while maximizing operational time. The useful actions of both floor cleaning and suction channel maintenance occur simultaneously.
3Ease of operation
If a flushing device is added to the suction foot, then ease of cleaning is improved, but device complexity increases
Solution Approach 1:
The invention applies merging by integrating the flushing device components directly into the existing suction foot structure. The flushing fluid supply line connects to the suction channel, and the flushing fluid opening is incorporated into the suction foot base. This combination allows the suction channel to be cleaned through the existing suction connection without requiring separate cleaning equipment or complex additional mechanisms, improving ease of cleaning while minimizing added complexity.
