Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional waste management methods are used at landfill sites, then operational simplicity is maintained, but environmental risk detection capability is insufficient
Solution Approach 1:
The patent creates a digital twin (virtual model) of the physical landfill environment that replicates real-world conditions. Sensors in the physical environment correspond to virtual sensors in the digital model, allowing risk detection and analysis in the virtual space without directly interfering with physical operations. This copying approach enhances detection capability while keeping physical system changes minimal.
Solution Approach 2:
The digital twin serves as an intermediary between the physical landfill environment and the risk detection/analysis system. Instead of directly monitoring the complex physical environment, the system uses the virtual model as a mediator to process sensor data, simulate environmental conditions, and identify risks. This intermediary layer simplifies the connection between physical sensors and risk assessment.
2Measurement precision
If comprehensive sensor data collection is implemented at debris locations, then measurement precision is improved, but device complexity increases
Solution Approach 1:
Instead of directly processing complex sensor data from multiple sources, the patent copies this data into a virtual environment where it can be processed more easily. The digital twin replicates the sensor network and environmental conditions, allowing for precise material identification through virtual analysis without managing the physical complexity of the sensor infrastructure.
Solution Approach 2:
The patent replaces direct physical analysis of debris with virtual simulation and analysis in the digital twin environment. Rather than using physical methods to identify and classify materials at the landfill site, the system uses computational algorithms in the virtual model to analyze sensor data and determine material composition, reducing the need for complex physical inspection equipment.
3Loss of information
If real-time augmented reality overlay is generated, then information availability is improved, but processing time and computational load increase
Solution Approach 1:
The patent performs preliminary processing of sensor data and pre-generation of AR overlay content in advance within the digital twin environment. By preparing visualization data beforehand in the virtual model, the system reduces the computational load during real-time display, allowing AR information to be presented with minimal delay when viewed through mobile devices or AR glasses at the landfill site.
Data Source
AI summary
A digital model is generated of a debris location where the digital model includes an augmented reality overlay of the debris location. Digital data from sensors at a debris field is received at a computer, and the digital data depicts debris in the debris field. Materials in the debris field are detected and identified based on the detected materials in the debris field. Layers of materials in the debris field are identified. A digital model is generated of the materials in the debris field including in the layers. Using the computer and an augmented reality (AR) device, an augmented reality overlay is generated based on the digital model of the materials in the debris fields. The augmented reality overlay is superimposed over the digital model of the materials in the debris field to indicate the materials in the debris field and the materials in the layers of the debris field.
