Flush-Mounted Vacuum Inlet With Foot-Activated Door Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional vacuum systems for non-carpeted surfaces are cumbersome, require manual dexterity, and can be stressful due to the need for bending and maneuvering, and existing flush-mounted vacuum fittings are not aesthetically pleasing or space-efficient, especially in open-plan living areas.
Innovation Solution
A vacuum assembly with a flush-mounted inlet door that can be activated by slight pressure, integrating a waste collection system with dual receiving holes and an electrical switch, allowing for convenient foot-activated operation and reducing the risk of accidental activation, featuring a spring-loaded door for dual tension and a micro switch for efficient power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional dustpan with rigid handle is used, then debris collection function is provided, but operator requires considerable bending or stooping which is stressful and fatiguing
Solution Approach 1:
The patent replaces the manual mechanical dustpan system with an automated vacuum system that uses electrical power and airflow to collect debris, eliminating the need for manual sweeping and dustpan manipulation. The vacuum cleaner with power head directly attaches to the inlet, substituting the mechanical broom-dustpan system with an electrically-powered suction system.
Solution Approach 2:
The patent introduces a kickboard-mounted vacuum inlet as an intermediary element between the floor and the vacuum cleaner. This inlet provides a fixed mounting point that eliminates the need to maneuver a complete vacuum cleaner across the room, allowing the power head to be positioned at the inlet while the main body can be placed in a convenient location.
2Ease of operation
If vacuum cleaner with long handle and hose is used, then ease of cleaning is improved, but difficulties in maneuvering across rooms and large storage space requirement occur
Solution Approach 1:
The patent divides the vacuum system into separate components: a fixed kickboard-mounted inlet and a movable vacuum cleaner with power head. The power head can be detached and positioned at the inlet for cleaning, while the main vacuum body can be stored in a compact location, reducing the space required for the complete system.
Solution Approach 2:
The patent transitions from a fully movable vacuum cleaner operating in two dimensions (across the floor) to a system where the power head operates at a fixed vertical dimension (kickboard inlet), eliminating the need to maneuver the complete vacuum across rooms while maintaining cleaning capability.
3Shape
If flush mounted vacuum fitting is installed, then aesthetic appearance and space efficiency are improved, but accidental activation risk increases
Solution Approach 1:
The patent incorporates a toe lift portion that extends outwardly from the flush-mounted fitting, providing a preliminary action mechanism that requires intentional foot pressure to activate. This preliminary action feature ensures that accidental contacts do not trigger the vacuum, while still maintaining the aesthetic flush-mounted appearance from most viewing angles.
4Ease of operation
If toe lift portion extends outwardly for activation, then ease of operation is improved, but flush mounted aesthetic appearance is compromised
Solution Approach 1:
The patent applies local quality by providing the toe lift portion only at the specific location where foot activation is needed, while the rest of the fitting maintains its flush-mounted appearance. The toe lift portion is positioned to extend outwardly only in the area required for operational access, while the surrounding fitting remains flush with the kickboard surface for aesthetic purposes.

AI summary
A vacuum assembly comprising: (a) an inlet having an open and closed position; (b) a waste collection member (c) a vacuum means for generating a flow of air from said inlet to said collection member; and (d) a switch adapted to interact with the inlet, wherein the inlet when open activates the switch to receive debris through the inlet. The assembly is flush mounted to an existing fitting.
