Solution Overview

Problem

Existing vacuum cleaners have a bulky design due to the placement of battery holders at the top, requiring users to remove batteries to access the filter cover for maintenance, which complicates access and increases the overall height, affecting heat dissipation and usability.

Innovation Solution

The vacuum cleaner features a battery cover that integrates the battery holder, allowing it to be positioned above the filter cover, enabling easy access without removing batteries, and is designed with a compact layout where the battery cover and filter cover are arranged laterally, alongside the suction unit and control unit, facilitating a more compact design and simplified maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If battery holders are placed at the top of the filter cover, then batteries can be accessed, but the overall height increases and access to the filter cover becomes complicated

Engineering Contradiction:
ImproveAccess to filter coverVSAvoidOverall height
Core Design Contradiction:
Ease of operationVSLength of stationary object

Solution Approach 1:

The battery holder is repositioned from a vertical arrangement on top of the filter cover to a lateral arrangement beside the filter cover. This spatial reconfiguration reduces the overall height requirement while maintaining accessibility to both the filter cover and battery holder through the same access opening.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If battery holders are placed at the top of the filter cover, then batteries can be accommodated, but access to filter cover requires removing batteries

Engineering Contradiction:
ImproveMaintenance accessVSAvoidAccess procedure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The access opening is designed as a shared entry point that provides independent access to both the filter cover and the battery holder. This segmentation of access paths allows users to reach either component without interfering with the other, eliminating the need to remove batteries to access the filter cover.

Inventive Principle:
Principle #1Segmentation

3Temperature

If battery holders are placed at the top of the filter cover, then batteries can be held, but heat dissipation is reduced

Engineering Contradiction:
ImproveHeat dissipationVSAvoidBattery holder positioning
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The battery holder is positioned in a lateral region with improved thermal characteristics, away from the confined space above the filter cover. This local repositioning allows for better heat dissipation pathways while maintaining the functional integration of the battery holder within the vacuum cleaner housing.

Inventive Principle:
Principle #3Local quality

AI summary

The invention relates to a vacuum cleaner (10/100) comprising a dirt collection container (28) for vacuumed material, a suction unit (42), at least one filter element (50) arranged between the dirt collection container (28) and a suction chamber (46) in the flow direction of the air suctioned by the suction unit (42), a filter cover (54) which covers the filter element (50) on the clean-area side, at least one rechargeable battery (90), and at least one battery receiving area (92). The aim of the invention is to provide a more compact design and facilitate access to the filter cover (54). This is achieved in that the vacuum cleaner (10/100) has a battery cover (70) which covers the at least one battery receiving area (92) and which is arranged above the filter cover (54) when the vacuum cleaner (10/100) is positioned on a floor surface (66) in an operating position. The battery cover (70) can be converted from a closed position, in which the battery cover covers the filter cover (54), into an open position, in which a user can access the filter cover (54) from the clean-area side, and back.
