Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction heads for vacuum cleaners are inefficient in picking up large-size debris and fine dust on carpets and hard surfaces, with increased power consumption and reduced motor power due to regulatory constraints, leading to a need for optimized components to maintain performance.
Innovation Solution
A base plate for the suction head with a front inclined surface at an angle of 10° to 20° and a rear inclined surface with a smaller angle, combined with velvet strips and a specific design to ensure adhesion and guide large-size debris into the suction channel, preventing pushing and enhancing suction efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If motor power is increased to improve suction performance, then suction efficiency is improved, but power consumption increases and violates regulatory constraints
Solution Approach 1:
The patent changes the geometric parameters of the base plate, specifically introducing inclined surfaces with optimized angles (10°-20° at the front, 5°-15° at the rear) to improve airflow dynamics and suction efficiency without increasing motor power
Solution Approach 2:
The base plate is segmented into distinct functional zones: a front inclined surface for debris guidance, a rear inclined surface for airflow optimization, and flat surfaces for sealing. This segmentation allows each zone to perform its specific function efficiently
2Productivity
If conventional base plate design is used, then manufacturing is simple, but suction efficiency for large-size debris and fine dust is insufficient
Solution Approach 1:
Different regions of the base plate are given different geometric qualities: the front surface has a steeper inclination (10°-20°) for debris deflection, while the rear surface has a gentler inclination (5°-15°) for airflow management, and lateral surfaces are flat for sealing contact
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution improves suction performance by effectively capturing large-size debris and fine dust, reducing power consumption, and maintaining performance comparable to higher-powered models while adhering to reduced power regulations.
Implementation Method 1
the front inclined surface is inclined upwardly so that the front side is raised with respect to the surface to be vacuumed... which conveys a large-size body towards the suction channel and prevents this body from being pushed in a forwards direction or from being pushed downwards
Implementation Method 2
a suction head for picking up dust, debris or fluids from a surface... a suction channel which, during use, is joined to the base plate and is in fluid communication with the base plate channel

AI summary
A base plate for a vacuum cleaner suction head is described, said base plate comprising a lower face, an upper face and a base plate channel open towards the surface to be vacuumed. The channel extends across the whole width of the base plate. The base plate channel comprises a front edge and a rear edge. The lower face comprises: a first surface which extends along the whole front edge of the channel and a second surface which extends along the whole rear edge of the channel, the first and second surfaces lying in a same horizontal plane. The lower face also comprises a front inclined surface extending from said first surface towards the front side. According to the invention, the front inclined surface is inclined upwards so that the front side is raised with respect to the surface to be vacuumed.
