Solution Overview

Problem

Existing floor cleaning devices, such as robotic vacuum cleaners and mops, require separate charging stations that disrupt the aesthetic appearance and occupy unnecessary space in the room.

Innovation Solution

A strip arrangement with integrated charging devices for floor cleaning devices, such as vacuuming and mopping robots, is designed to conceal the charging mechanism within a skirting board, allowing for contact-based or contactless energy transfer, maintaining a cohesive room appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a separate charging station is used for floor cleaning devices, then the charging function is provided, but the aesthetic appearance of the room is disrupted and unnecessary space is occupied

Engineering Contradiction:
Improvecharging functionVSAvoidspace occupied in room
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The charging device is integrated into the strip arrangement, merging the charging function with the existing skirting board structure. This eliminates the need for a separate charging station and optimizes space usage by utilizing the vertical space behind the strip rather than occupying floor space.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The charging device is nested within the strip arrangement, specifically utilizing the hollow profile's interior space to house the charging mechanism. This nesting approach allows the charging function to be concealed within the existing structure, maintaining aesthetic appearance while providing the charging capability.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If a separate charging station is used for floor cleaning devices, then the charging function is provided, but the aesthetic appearance of the room is disrupted

Engineering Contradiction:
Improvecharging functionVSAvoidaesthetic appearance
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The charging device is merged with the strip arrangement, creating a unified structure that maintains the clean lines and aesthetic appearance of the room. The charging function is provided without the visual disruption of a separate charging station.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The charging device is nested within the hollow profile of the strip arrangement, concealing the charging mechanism behind the cover profile. This nesting approach allows the charging function to be hidden, maintaining the aesthetic appearance of the room while providing the necessary charging capability.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Area of stationary object

If the charging device is integrated into the strip arrangement, then space is optimized and aesthetics are maintained, but the charging device requires interior space within the strip

Engineering Contradiction:
Improvespace usageVSAvoidinterior space required
Core Design Contradiction:
Area of stationary objectVSVolume of stationary object

Solution Approach 1:

The charging device is nested within the hollow profile's interior space, utilizing the existing void space behind the strip arrangement. This nesting approach allows the charging device to be housed within the strip structure without requiring additional space, as the hollow profile already provides the necessary volume.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The charging device utilizes the vertical dimension and the space behind the strip arrangement rather than occupying horizontal floor space. By transitioning from a floor-based charging station to a wall-mounted integrated solution, the invention optimizes space usage by utilizing the third dimension (depth behind the strip).

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