Self-Propelled Vacuum Power Split for Textile Floor Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-propelled vacuum-cleaning devices are inadequate for cleaning both smooth and textile floor coverings, as they lack sufficient cleaning capacity on textile surfaces due to limited power allocation.
Innovation Solution
A self-propelled vacuum-cleaning device with a maximal electric power range of 150-300 watts, prioritizing 120-220 watts for the vacuum blower and 10-40 watts for the roller drive, along with variable power control and height adjustment, to effectively clean both smooth and textile surfaces with a rechargeable battery or fuel cell power source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the maximal electric power is increased above 300 watts, then the cleaning capacity on textile floor coverings is improved, but the weight and size of the power source increases disproportionately
Solution Approach 1:
The patent optimizes the power consumption parameters of individual components (vacuum blower, roller drive, drive mechanism, control electronics) to achieve a balanced power distribution that maximizes cleaning capacity within the 150-300 watt range, preventing disproportionate weight increase
2Weight of moving object
If the maximal electric power is decreased below 150 watts, then the weight of the power source is reduced, but the cleaning capacity on textile floor coverings becomes insufficient
Solution Approach 1:
The patent establishes minimum power thresholds (150-300 watts) and optimizes the distribution among components to ensure sufficient cleaning capacity on textile floor coverings while minimizing power source weight

AI summary
A self-propelled vacuum-cleaning device for cleaning smooth and textile floor coverings, particularly in the private home sector. The device has a housing, a vacuum blower, an electrically driven cleaning roller, an electrical drive mechanism, control electronics, and a power source. The maximal electric power of the self-propelled vacuum-cleaning tool lies between 150 watts and 300 watts during cleaning operation, whereby between 120 watts and 220 watts are allocated to the vacuum blower, between 10 watts and 40 watts are allocated to the electrical roller drive for the cleaning roller, and between 5 watts and 40 watts are allocated to the drive mechanism, and whereby the control electronics have a power demand of less than 5% of the maximal electric power.
