Solution Overview

Problem

Existing soil cultivation devices are limited in mobility due to increased weight from liquid containers and lack the ability to perform both polishing and wet cleaning effectively, with restricted lateral movement.

Innovation Solution

A hand-held soil cultivation device with a structurally separate suction unit, a liquid supply system integrated into the guide part, and an optional external power supply, allowing for efficient liquid management and reduced weight, enabling easy maneuverability and simultaneous polishing and wet cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If liquid containers are attached to the device itself, then wet cleaning function is enabled, but weight increases and mobility is reduced

Engineering Contradiction:
Improvewet cleaning functionVSAvoiddevice weight
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The device is divided into separate functional modules: a lightweight base part with polishing tools and a separate suction unit with liquid container. This segmentation allows the base part to remain light for easy mobility while the suction unit provides wet cleaning functionality through its integrated liquid container and suction turbine.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A hose acts as an intermediary connection between the base part and the suction unit, allowing liquid to be transported from the suction unit's container to the base part's working area. This intermediary connection enables wet cleaning functionality without requiring the heavy liquid container to be attached to the base part itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If liquid containers are attached to the device itself, then wet cleaning function is enabled, but lateral mobility is restricted

3Device complexity

If the suction unit is integrated into the base part, then structural simplicity is achieved, but weight increases and mobility is reduced

Engineering Contradiction:
Improvestructural simplicityVSAvoidbase part weight
Core Design Contradiction:
Device complexityVSWeight of moving object

Solution Approach 1:

The device is divided into separate functional modules: a lightweight base part with polishing tools and a separate suction unit with liquid container. This segmentation allows the base part to remain light for easy mobility while the suction unit provides wet cleaning functionality through its integrated liquid container and suction turbine.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base part is designed to be universally applicable for polishing operations without being burdened by additional functions. The suction unit serves as a separate multi-functional module that can be connected via hose to provide both liquid supply and liquid collection capabilities, allowing the base part to remain simple and lightweight.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The invention relates to a handheld floor treatment device, comprising a floor part (1), which has a liquid supply (11), and a liquid intake (13) and a structurally separated suction unit that contains at least one suction turbine (17). The invention further relates to a handheld floor treatment device, comprising a floor part (1) having a bow (5), which encompasses the floor part (1) at least in some sections and which is connected to the floor part (1) by means of a first joint (4) that can be adjusted in the treatment direction (6), and further comprising a guide part (2) attached to the bow (5), the guide part having a handle (3). The guide part (2) comprises a further joint (8) at the lower end below the center but above the floor part (1), about which joint the guide part (2) can be adjusted transversely to the treatment direction (6) so that the floor part (1) can be rotated by a user (P) parallel to the treatment surface (B) about a vertical axis (A1) of the floor part (1) by at least ±45°, even if the guide part (2) is in a tilted position.
