Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices, such as floor scrubbers, require frequent user intervention to check the water level in the wastewater tank to avoid overflow and lack convenient detection of proper tank assembly, leading to poor user experience.
Innovation Solution
Incorporation of a first sensing assembly with two symmetrical floats in the wastewater tank, allowing for real-time detection of water level and tank assembly status, using induction signals to alert the user when the tank is full or improperly assembled, and a filter mesh pouch for efficient wastewater filtration during dumping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a water level detection system is added to the wastewater tank, then overflow risk is reduced, but device complexity increases
Solution Approach 1:
The patent replaces complex electronic water level detection systems with a simple magnetic float mechanism. The float contains a magnet that interacts with a Hall sensor, providing reliable water level detection through magnetic field interaction rather than complex electrical circuits. This mechanical-magnetic approach maintains reliability while minimizing device complexity
Solution Approach 2:
The wastewater tank system performs self-detection of its own water level through the integrated float mechanism. The float automatically rises and falls with water level changes, triggering detection without requiring external monitoring systems. The tank essentially detects itself, reducing the need for additional complex detection infrastructure
2Reliability
If assembly status detection is implemented, then improper assembly is prevented, but device complexity increases
Solution Approach 1:
The patent combines water level detection and assembly status detection into a single integrated float mechanism. The same float that detects water level also indicates assembly status through its position relative to the tank body. This merging of functions eliminates the need for separate detection systems, reducing overall device complexity while maintaining reliable detection of both parameters
Solution Approach 2:
The float mechanism serves multiple functions: it detects water level, indicates assembly status, and provides visual feedback to the user. This multi-functional design allows a single component to perform what would traditionally require multiple separate systems, thereby reducing device complexity while improving reliability through comprehensive monitoring
3Device complexity
If manual water level checking is required, then device complexity is reduced, but user convenience deteriorates
Solution Approach 1:
The patent implements automatic feedback through the float mechanism that provides real-time information about water level and assembly status. The float's position gives immediate visual feedback to the user, eliminating the need for manual checking. This automatic feedback system maintains simple device architecture while dramatically improving ease of operation by keeping users informed without requiring their active involvement
4Reliability
If filtration system is added during dumping, then filtration efficiency is improved, but device complexity increases
Solution Approach 1:
The patent extracts the filtration function from the main device body and places it in a removable filter bag that is easily attached and detached. This extraction allows the filtration system to be added only when needed during the dumping process, rather than being a permanent integrated component. The result is improved filtration efficiency without permanently increasing device complexity, as the filtration element can be removed when not in use
