Vacuum Cleaner Tool Holder Lighting for Dark Parking Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it difficult to insert the suction tool into the holding device of vacuum cleaners, especially in dark environments, as existing solutions lack adequate illumination for the parking position.
Innovation Solution
Incorporating a lighting device within and adjacent to the holding device, with a light source and light guide for direct illumination, and a switching device for delayed lighting after the vacuum cleaner is switched off, ensuring visibility for 30-60 seconds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a holding device for receiving a suction tool is provided on the housing, then the suction tool can be stored in a parking position, but the user cannot easily see or insert the suction tool into the holding device in dark environments
Solution Approach 1:
The lighting device is activated automatically before the user needs to insert the suction tool, specifically when the vacuum cleaner is switched off or disconnected from mains voltage. The lighting remains on for a predetermined time (30-60 seconds) to provide adequate illumination for the insertion operation, then switches off automatically to save energy.
Solution Approach 2:
The lighting system serves itself by automatically detecting when the vacuum cleaner is switched off or unplugged, activating the lights without user intervention, and automatically timing the duration of illumination. The system manages its own operation cycle without requiring manual control.
2Ease of operation
If the lighting device remains on after switching off the vacuum cleaner, then the user can see the holding device for insertion, but energy is wasted during the lighting period
Solution Approach 1:
The lighting device operates periodically rather than continuously - it activates only during specific periods when the vacuum cleaner is switched off or disconnected from mains voltage, and deactivates after a predetermined time interval (30-60 seconds). This periodic operation provides necessary illumination while minimizing energy consumption during non-essential periods.
Solution Approach 2:
The lighting is activated in advance of when the user actually needs to insert the suction tool, specifically when the vacuum cleaner is switched off or unplugged. The lighting remains on for a predetermined time that is sufficient for the insertion operation, then switches off automatically, providing illumination only when and for as long as it is actually needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances user convenience by providing sufficient illumination for inserting the suction tool in dark conditions and improving flexibility when parking the vacuum cleaner, especially in dark rooms.
Implementation Method 1
the lighting device comprises at least one light source arranged in the housing and a light guide assigned to the light source and projecting up to the housing surface

AI summary
The cleaner (1) has a holder (4) for holding a suction tool in a parked position and arranged at a housing (2). An illumination device e.g. parking lights (9, 10) and a light strip (11) are attached at the holder. The holder is divided into a guiding region and a holding region, and the lights are arranged at the guiding region and the holding region. The illumination device comprises a light source i.e. LED and optical fibers, that are projected at a housing surface and attached at the light source. A switching device is attached to the illumination device.
