Pivoting Handle and Suction Diverter for Focused Edge Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum cleaners lack effective edge cleaning capabilities and efficient debris removal, particularly along surfaces like baseboards and edges, and often have cumbersome designs that complicate storage.
Innovation Solution
A surface cleaning apparatus featuring a base unit with a pivoting handle and diverter assembly that allows for selective restriction of the suction nozzle, enhancing edge cleaning by focusing suction and providing improved illumination for better visibility, while also allowing the handle to be easily folded for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the suction nozzle is restricted to focus suction at edges, then edge cleaning performance is improved, but the overall cleaning area is reduced
Solution Approach 1:
The suction nozzle is made movable relative to the cleaner body through a positioning mechanism, allowing it to be dynamically positioned between a first position for general cleaning and a second position for edge cleaning. This dynamic repositioning enables the system to adapt its cleaning focus based on the task requirements, resolving the contradiction between focused edge cleaning and overall cleaning area coverage.
2Volume of moving object
If the handle is made foldable for compact storage, then storage space requirement is reduced, but the structural complexity increases
Solution Approach 1:
The handle is designed with a folding mechanism that allows it to be dynamically reconfigured between an extended operational position and a folded storage position. This dynamic capability enables compact storage while maintaining full functionality during use, addressing the contradiction between storage compactness and structural simplicity.
3Difficulty of detecting and measuring
If illumination is added for edge visibility, then edge detection capability is improved, but energy consumption increases
Solution Approach 1:
Illumination elements are positioned to provide preliminary lighting of the edge area before the suction nozzle reaches it, enabling the user to detect and identify edges in advance. This preliminary illumination action allows for better edge detection while using energy efficiently by illuminating only the immediate working area rather than the entire path.
