Cordless Vacuum Battery Pack Layout Around the Dirt Container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum cleaners, especially battery-powered hand-holdable models, face challenges in compact design due to bulky components like battery packs and dirt containers, which hinder ergonomic handling and storage.
Innovation Solution
The integration of a battery pack with a curvilinear or annular cross-sectional profile that embraces the dirt container, allowing for a smoother and more compact design, with the battery pack being detachable for recharging and easy replacement, and the use of a two-stage cyclonic separation apparatus for efficient dust and dirt collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If battery packs and dirt containers are designed as separate bulky components, then each component can be optimized for its function, but the overall vacuum cleaner size increases and ergonomic handling becomes difficult
Solution Approach 1:
The patent combines the battery pack and dirt container into a single integrated housing structure. The battery pack is positioned within the housing to embrace the dirt container, creating a compact unified assembly that reduces overall vacuum cleaner size while maintaining ergonomic handling characteristics.
Solution Approach 2:
The battery pack is nested within the housing structure in such a way that it embraces the dirt container. This nesting arrangement allows the battery pack to partially surround the dirt container, maximizing space utilization and minimizing the overall volume of the vacuum cleaner.
2Ease of repair
If battery packs are made detachable for easy recharging and replacement, then maintenance becomes easier, but the connection reliability and sealing may be compromised
Solution Approach 1:
The housing is divided into a detachable battery pack portion and a main body portion. The battery pack can be easily removed and reattached, facilitating convenient recharging and replacement while maintaining connection reliability through proper interface design.
3Shape
If conventional separate component design is used, then manufacturing is simpler, but the vacuum cleaner lacks compactness and smooth profile
Solution Approach 1:
The battery pack and dirt container are merged into a single integrated housing structure, creating a smooth external profile without protruding components. This integration achieves a compact, aesthetically pleasing design while managing the complexity through modular assembly techniques.
