Solution Overview

Problem

Current methods for planning routes for mobile technical systems in buildings do not adequately assess the suitability of routes based on the specific parameters and conditions of the system, such as weight, dimensions, and environmental factors, potentially leading to collisions or operational failures.

Innovation Solution

A computer-implemented method and device that utilize a spatial model of the building to read in route and system parameters, derive boundary conditions, and check each point on the route for compliance, issuing results and allowing for real-time adjustments or warnings, with integration into building management systems and sensors for environmental data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If path planning algorithms are used to determine routes for mobile technical systems, then the route can be planned based on boundary conditions like walls and passageways, but the suitability of the route for specific system parameters (weight, dimensions, environmental factors) is not adequately assessed

Engineering Contradiction:
Improveroute planningVSAvoidroute suitability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies preliminary action by performing a simulation of the mobile technical system moving along the planned route before actual operation. The simulation checks boundary conditions, system parameters, and environmental factors in advance to validate route suitability, preventing operational failures before they occur.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses a simulation model that creates a virtual copy of the mobile technical system and the building environment. This digital twin approach allows testing the route in a virtual environment without physical risks, assessing parameters like weight, dimensions, and environmental conditions before real-world deployment.

Inventive Principle:
Principle #26Copying

2Device complexity

If traditional path planning only considers boundary conditions like walls and passageways, then the planning process is simple, but the route may not be suitable for the specific parameters of the mobile technical system such as weight, dimensions, and environmental factors

Engineering Contradiction:
Improvepath planning processVSAvoidroute validation accuracy
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The patent applies parameter changes by expanding the validation criteria from simple boundary conditions to multiple system-specific parameters including weight, dimensions, heat resistance, turning radius, and environmental factors. The simulation model dynamically adjusts and checks these parameters to ensure the route is suitable for the specific mobile technical system.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a universal simulation framework that can validate routes for different types of mobile technical systems with varying parameters. The system handles diverse requirements (weight-bearing capacity, dimensional constraints, environmental conditions) through a single multi-functional validation process that adapts to different system types.

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

3Reliability

If a simulation model with Building Information Modeling (BIM) is used to verify route characteristics, then route suitability can be assessed comprehensively, but the complexity of the system increases

Engineering Contradiction:
Improveroute verificationVSAvoidsimulation system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the path planning algorithm with the simulation model into an integrated system. The boundary condition checking and parameter validation are combined in a single simulation process that uses BIM data, reducing the need for separate verification steps and managing complexity through unification.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The simulation model acts as an intermediary between the path planning algorithm and the actual mobile technical system operation. It translates planning data into validated route recommendations by checking all necessary parameters, serving as a mediator that simplifies the interface between planning and execution while ensuring comprehensive validation.

Inventive Principle:
Principle #24Intermediary (Mediator)
