Accessory for a vacuum cleaner suction head for collecting large debris
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suction heads for vacuum cleaners compromise on suction efficiency when dealing with large-size debris on smooth surfaces like marble, cement, and tiled floors, while maintaining efficiency on other types of surfaces such as carpets.
Innovation Solution
An accessory with a transverse elongated slot and spacer members, including longitudinal ribs and roller wheels, is removably coupled to the suction head to enhance suction efficiency for large-size debris on smooth surfaces without affecting performance on other surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional suction head is used to maintain suction efficiency on carpets and various surfaces, then suction efficiency on smooth surfaces for large-size debris deteriorates
Solution Approach 1:
The suction head is divided into modular components: a base plate for general surface cleaning and a removable accessory piece with transverse slot and spacer members for large debris on smooth surfaces. This segmentation allows each component to be optimized for specific functions while maintaining overall versatility through reconfiguration.
Solution Approach 2:
The accessory piece can be dynamically attached or detached from the base plate depending on the cleaning task. This dynamic reconfiguration enables the suction head to adapt its structure for different surface types and debris sizes, optimizing performance for each specific scenario.
2Productivity
If the suction head structure is modified to improve suction for large-size debris on smooth surfaces, then suction characteristics on other types of surfaces are affected
Solution Approach 1:
The specialized features for large debris handling (transverse slot, spacer members) are extracted into a separate removable accessory piece rather than being integrated into the base plate. This extraction allows the base plate to maintain its original suction characteristics for various surfaces while the accessory provides enhanced capability when needed.
Solution Approach 2:
The accessory piece acts as an intermediary component between the base plate and the large-size debris on smooth surfaces. It provides the necessary structural modifications (slot and spacers) only when required, without permanently altering the base plate's performance on other surface types.
3Productivity
If spacer members are added to maintain distance from the surface for large debris suction, then device complexity increases
Solution Approach 1:
The spacer members are merged with the accessory piece structure rather than being separate components. This integration reduces overall device complexity by combining multiple functions (spacing, debris guidance, structural support) into a single unified component that attaches to the base plate.
