Accessory for a suction nozzle of vacuum cleaners or the like
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suction nozzles for vacuum cleaners compromise on suction efficiency when cleaning hard and smooth surfaces like marble, cement, or tiles, while maintaining adequate performance on carpeted or pile surfaces.
Innovation Solution
An accessory with a main body featuring elongate slots and strips of sliding material, such as fibrous or synthetic fibers, is coupled with the suction nozzle to enhance suction efficiency on smooth surfaces without altering performance on other types. The accessory includes a first strip along the front edge and a second strip along the rear edge of the slot, with optional stabilizing strips, and is securely attached using adhesives or mechanical fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional suction nozzle is designed to clean both hard surfaces and carpets, then it maintains adequate performance on carpeted surfaces, but suction efficiency on hard and smooth surfaces deteriorates
Solution Approach 1:
The suction nozzle is divided into modular components: a base plate for hard surfaces and an interchangeable accessory (brush roll or extension tube) for carpeted surfaces. This segmentation allows each component to be optimized for its specific function, resolving the contradiction between versatility and specialized performance.
Solution Approach 2:
The suction nozzle incorporates adjustable elements such as variable brush roll heights, adjustable air flows, and interchangeable attachments that can be dynamically configured based on the surface type being cleaned, enabling optimal performance across different surface conditions.
2Productivity
If the suction nozzle is optimized for hard surfaces, then suction efficiency on smooth surfaces improves, but performance on carpeted or pile surfaces deteriorates
Solution Approach 1:
The suction nozzle employs universal coupling mechanisms and interchangeable attachments that enable a single base unit to perform effectively on multiple surface types. The base plate with optimized suction characteristics for hard surfaces can accommodate various attachments for carpets, maintaining versatility while achieving superior performance on smooth surfaces.
3Device complexity
If a single suction nozzle design is used for all surface types, then device complexity is reduced, but suction efficiency on specific surfaces like marble or tiles deteriorates
Solution Approach 1:
The suction nozzle is segmented into a simple base plate and separate functional attachments. The base plate maintains a straightforward structure for ease of manufacture, while specialized attachments (brush rolls, extension tubes) provide surface-specific optimization without complicating the core design.
Solution Approach 2:
A universal coupling mechanism acts as an intermediary between the simple base plate and various specialized attachments. This mediator enables easy interchange of components, allowing the system to achieve high suction efficiency on specific surfaces like marble or tiles without permanently increasing device complexity.
