Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Upright vacuum cleaners face issues with metal objects damaging internal components and being propelled by the rotary brush, and existing guards increase cost, footprint, and complexity, affecting maneuverability and aesthetics.
Innovation Solution
Incorporating magnet assemblies with brackets and magnets positioned on shelves within recesses in the cleaning head to prevent metal objects from entering, which are removably attached to reduce assembly time and maintain a sleek design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If guards are added to prevent metal objects from entering the cleaning head, then protection against damage is improved, but device complexity and cost increase
Solution Approach 1:
The harmful metal objects are extracted from the debris stream using magnetic force before they can enter the cleaning head and cause damage. The magnet assembly selectively removes ferrous debris through magnetic attraction, separating it from the airflow path.
Solution Approach 2:
A magnet assembly serves as an intermediary component positioned between the debris source and the cleaning head. This intermediate magnetic field captures metal objects without requiring physical contact or complex mechanical guards, simplifying the overall system design.
2Reliability
If guards are added to prevent metal objects from entering the cleaning head, then protection against damage is improved, but manufacturing cost increases
Solution Approach 1:
The magnet assembly uses inexpensive permanent magnets and simple bracket components that can be easily manufactured and replaced if needed. This approach avoids costly complex mechanical guard systems while providing effective protection.
Solution Approach 2:
The solution extracts only the essential protective function using a simple magnet assembly, eliminating the need for expensive complex guard mechanisms. The magnetic field provides protection through a minimal, cost-effective component structure.
3Reliability
If guards are added to prevent metal objects from entering the cleaning head, then protection against damage is improved, but the footprint and maneuverability are worsened
Solution Approach 1:
The magnet assembly is nested within the existing vacuum cleaner structure, utilizing the space around the cleaning head without adding external protruding guards. The magnetic components are integrated into the housing, maintaining a compact footprint.
Solution Approach 2:
Instead of adding external guards that increase horizontal footprint, the solution uses magnetic fields that extend in three-dimensional space around the cleaning head. The magnetic protection zone encompasses the area without requiring additional physical space or structural extensions.
4Reliability
If guards are added to prevent metal objects from entering the cleaning head, then protection against damage is improved, but aesthetics are worsened
Solution Approach 1:
The magnet assembly is nested within the cleaning head housing, with the magnetic components concealed inside the structure. The bumper and housing panels provide a smooth external appearance, hiding the protective magnetic components from view while maintaining aesthetic design.
Solution Approach 2:
The bumper serves as an aesthetic intermediary that provides a clean external surface while the magnetic protection occurs internally. This allows the vacuum cleaner to maintain its designed appearance while incorporating protective functionality without visible guards or protrusions.

AI summary
An upright vacuum cleaner includes a blower for pulling air and debris through the upright vacuum cleaner, a motor connected to the blower, and a cleaning head for removing the debris from a floor. The cleaning head includes a front wall, a rear wall, a first sidewall, and a second sidewall. The first sidewall and the second sidewall extend between the front wall and rear wall. The vacuum cleaner further includes a debris tube connected to the cleaning head for receiving the debris from the cleaning head. The vacuum cleaner also includes magnet assemblies adapted to prevent metal objects from entering the cleaning head. Each magnet assembly includes a bracket and a magnet. The bracket includes a horizontal plate and a vertical plate. The magnet is connected to the vertical plate. The front wall includes shelves to support the magnet assemblies. Each shelf is arranged to receive one of the magnet assemblies such that the horizontal plate rests on the shelf and the magnet is positioned below the shelf.
