Solution Overview

Problem

Existing autonomous mobile outdoor soil cultivation robots lack user-friendly features, particularly in terms of visibility and operation under outdoor conditions such as direct sunlight and under bushes.

Innovation Solution

The robot is equipped with a large screen surface, air cooling circuit, and protective cover to ensure clear visibility and robust operation, featuring a screen surface that is at least 5% of the outer contour, translucent or transparent, with an air cooling system and protective housing to maintain functionality under outdoor conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a small screen is used to reduce device complexity, then the device complexity is reduced, but the screen visibility under outdoor conditions deteriorates

Engineering Contradiction:
Improvescreen visibilityVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines multiple functions into the housing structure: the housing serves as both the protective enclosure and the mounting structure for the screen device, eliminating the need for separate mounting brackets or frames. This integration maintains a clean design while supporting the larger screen area needed for outdoor visibility.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If no protective cover is used to simplify the structure, then the device complexity is reduced, but the protection against environmental factors deteriorates

Engineering Contradiction:
Improveprotection against environmental factorsVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The housing structure performs multiple functions simultaneously: it provides mechanical protection against environmental factors, serves as the mounting structure for the screen device, and defines the overall device geometry. This multi-functionality reduces the need for additional protective components while maintaining reliability.

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

Solution Approach 2:

The housing is designed as a continuous protective shell that encloses the screen device and other components, providing environmental protection through a unified structural element rather than multiple separate protective parts.

Inventive Principle:
Principle #30Flexible shells and thin films

3Ease of operation

If a large screen surface is used to improve visibility, then the screen visibility is improved, but the device complexity increases

Engineering Contradiction:
Improvescreen visibilityVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The housing structure is designed with localized features specifically optimized for screen mounting: a flat upper surface area dedicated to screen placement, appropriate structural reinforcement only where needed for screen support, and streamlined contours elsewhere. This targeted approach enables large screen visibility without unnecessarily increasing overall device complexity.

Inventive Principle:
Principle #3Local quality

AI summary

The invention relates to an autonomous mobile outdoor flooring robot (1), wherein the outdoor flooring robot (1) has at least an upper outer contour (2), the outer contour (2) comprising a contour surface (3) in a top view of the outdoor flooring robot (1), and a screen device (4), the screen device (4) comprising a screen area (5), and wherein a size (5W) of the screen area (5) in the top view of the outdoor flooring robot (1) corresponds to at least 5% of a size (3W) of the contour surface (3). This allows a user of the outdoor flooring robot to clearly see the screen area, particularly when working under a bush, outdoors, or at a distance. This improves usability.
