Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If construction machines are integrated with BIM models using existing methods, then some digital information connection is achieved, but significant advantages in control efficiency and safety are not realized

Engineering Contradiction:
Improvecontrol safetyVSAvoidintegration complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a control system as an intermediary between the BIM model and construction machines. The control system receives digital information from the BIM model (including working area limitations and machine selection criteria) and translates it into actionable control signals for the construction machines, thereby achieving safe and efficient control without direct complex integration between BIM and machine systems

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical control methods with digital information-based control. By substituting physical control mechanisms with digital data flow from BIM models (including automated working area boundary transmission and machine parameter optimization), the system achieves improved safety and efficiency while reducing the need for complex mechanical integration systems

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If working area limitations are statically defined, then simple control is maintained, but dynamic adaptation to construction progress is not achieved

Engineering Contradiction:
Improveworking area adaptabilityVSAvoidcontrol simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements dynamic working area limitations that automatically adapt to construction progress. The system continuously updates the digital representation of working area boundaries based on real-time construction status, allowing the control system to adjust machine operating zones dynamically without requiring manual intervention, thus maintaining both adaptability and operational simplicity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent incorporates feedback mechanisms where the actual construction progress is continuously monitored and compared with the BIM model data. This feedback loop enables the system to automatically update working area limitations based on the current construction state, achieving dynamic adaptability while keeping the control process automated and simple

Inventive Principle:
Principle #23Feedback

3Productivity

If manual machine selection and logistics planning is performed, then flexibility is maintained, but time consumption and efficiency are reduced

Engineering Contradiction:
Improvemachine selection efficiencyVSAvoidplanning time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent enables the system to automatically perform machine selection and logistics planning based on BIM model data and construction requirements. The control system autonomously optimizes machine parameters, selects appropriate equipment, and plans logistics without manual intervention, thereby significantly improving efficiency and reducing planning time while maintaining flexibility through automated decision-making

Inventive Principle:
Principle #25Self-service

4Reliability

If construction operators receive traditional training, then basic operation skills are taught, but realistic simulation of actual working conditions is not provided

Engineering Contradiction:
Improveoperator training qualityVSAvoidsimulation system complexity
Core Design Contradiction:

Solution Approach 1:

The patent creates a digital copy of the actual construction site and working conditions within the BIM model environment. This virtual replica allows operators to train in a realistic simulation that mirrors actual working conditions, including dynamic working area limitations and real machine parameters, without requiring complex physical simulation equipment

Inventive Principle:
Principle #26Copying

AI summary

The present invention relates to a method and a device for controlling the operation of a construction machine, in particular in the form of a crane, using a building information model (BIM) that contains digital information about a structure to be erected and/or modified. The invention also relates to the construction machine itself, which can be connected to and controlled using such a BIM.It is proposed to automatically detect a component located in the detection and/or working area of ​​the construction machine by means of a detection device, which may include a low-frequency LWID identification system mounted on the load hook and a camera, whereby, depending on the detected component, position data specifying the destination of the component and/or travel data specifying the travel path of the component are provided from the building information model, and the construction machine control device automatically lifts and/or moves the component depending on the aforementioned position data and/or travel data.
