Solution Overview

Problem

Existing robotic lawnmower control systems fail to provide safe and dynamic movement within geographical areas, particularly in sensitive environments like airport runways, and do not account for dynamic constraints such as flooding or local activities.

Innovation Solution

A mobile robot equipped with a navigation system that includes a receiver for position data, an electronic module for comparing robot position to predefined geographic and sub-area parameters, allowing for secure and dynamic movement control by modifying sub-area parameters remotely without altering physical barriers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple electric cable is used to delimit the geographical area, then the device complexity is reduced, but the reliability of movement limitation in sensitive areas is insufficient

Engineering Contradiction:
Improvemovement control systemVSAvoidmovement limitation
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The geographical area is segmented into multiple sub-areas, each with its own parameters and constraints. The navigation system independently manages parameters for each sub-area, allowing granular control over robot movement in different zones while maintaining overall system reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically adjusts robot movement constraints based on real-time conditions in different sub-areas. Parameters such as speed limits, operational restrictions, and access permissions can be modified remotely for specific sub-areas without affecting the entire geographical area, enabling adaptive response to changing conditions.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If a fixed geographical area definition is used, then the stability of the control system is improved, but the adaptability to dynamic constraints is reduced

Engineering Contradiction:
Improvecontrol systemVSAvoidresponse to dynamic constraints
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The system maintains stable overall geographical area boundaries while allowing dynamic modification of sub-area parameters. Remote access enables real-time updates to sub-area definitions, constraints, and operational parameters without destabilizing the core control system architecture.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system allows modification of parameters defining sub-areas and their constraints through remote access. This enables adaptation to dynamic conditions such as flooding, maintenance activities, or changing operational requirements while maintaining the stability of the overall geographical area definition.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If remote access is enabled for modifying parameters, then the ease of operation is improved, but the security against unauthorized modification is reduced

Engineering Contradiction:
Improveparameter modificationVSAvoidparameter security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system implements validation mechanisms that provide feedback on parameter modifications. Remote access requests are validated against predefined criteria and electronic signatures, ensuring that only authorized parameter changes are applied while maintaining ease of operation for legitimate modifications.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system employs preventive security measures including electronic signatures and validation protocols that act before parameter modifications are applied. These preliminary anti-actions prevent unauthorized modifications while allowing legitimate remote access for parameter adjustments.

Inventive Principle:
Principle #9Preliminary anti-action
