Vacuum Cleaner Nozzle with Pivoting Teeth for Multi-Position Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaner accessories lack versatility in cleaning positions and storage, limiting their ability to effectively clean various surfaces and areas efficiently.
Innovation Solution
An accessory tool for a vacuum cleaner featuring a pivotable nozzle with interlocking teeth mechanisms and a movable conduit, allowing the nozzle to transition between a narrow first cleaning position and a wider second cleaning position, as well as a storage position, enhancing cleaning capabilities and ergonomic usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the nozzle is fixed in a single position, then the structure is simple, but the cleaning versatility is limited
Solution Approach 1:
The nozzle is designed with pivotable portions that can rotate between different positions (first cleaning position, second cleaning position, and storage position). The interlocking teeth mechanism enables controlled dynamic movement while maintaining stability in each position, allowing the nozzle to adapt to various cleaning scenarios without requiring multiple separate attachments.
2Adaptability or versatility
If the nozzle can access tight areas, then the cleaning coverage is improved, but the storage space requirement increases
Solution Approach 1:
The nozzle portions are designed to nest within each other when pivoted to the storage position. The first portion can be positioned inside or alongside the second portion, creating a compact configuration that minimizes storage space while maintaining the capability to extend to tight areas when needed.
3Productivity
If the nozzle has multiple cleaning positions, then the cleaning efficiency is improved, but the mechanism complexity increases
Solution Approach 1:
The interlocking teeth mechanism is designed to automatically engage and disengage as the nozzle portions pivot between positions. The teeth on the first portion interact with teeth on the second portion to provide automatic positioning and locking without requiring external actuators, motors, or complex control systems, thereby maintaining mechanical simplicity while enabling multiple cleaning positions.

AI summary
An accessory tool for a vacuum cleaner includes a conduit and a nozzle. The conduit includes a first end coupled to the vacuum cleaner and a second end opposite the first end. The nozzle is coupled to the second end and includes a first portion with a first set of teeth and a first channel with an opening opposite the first set of teeth. The nozzle also includes a second portion with a second set of teeth and a second channel with an opening opposite the second set of teeth. The first set of teeth interlock with the second set of teeth, and are configured to cause the first portion and the second portion to pivot together relative to the conduit between a closed position and an open position. The nozzle is movable along an outer surface of the conduit from the second end toward the first end.
