Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If construction assist systems use only operation data from high-performing operators, then the quality of operation guidance is improved, but the system fails to reflect actual worksite conditions and reduces adaptability to different environments
Solution Approach 1:
The system segments the guidance approach into two components: (1) operation data from high-performing operators for technical guidance quality, and (2) real-time worksite environment data for contextual adaptation. This segmentation allows each component to fulfill its specific function while together they resolve the contradiction between guidance quality and adaptability.
Solution Approach 2:
The system introduces an intermediary virtual environment that mediates between the operation data and actual worksite conditions. This virtual space integrates both high-quality operation patterns and real-time environmental data, allowing the system to provide guidance that is both technically sound and contextually appropriate without directly combining the conflicting data sources.
2Adaptability or versatility
If the system simulates shovel motion in a virtual environment based on real worksite data, then worksite condition reflection is improved, but system complexity increases
Solution Approach 1:
The system creates a virtual copy of the worksite environment rather than directly modifying or analyzing the physical environment. This copying approach allows the system to reflect actual worksite conditions through sensors and space recognition devices while maintaining manageable complexity by working with digital representations rather than physical system modifications.
3Measurement precision
If real-time sensor data and space recognition devices are used to create virtual environment, then worksite awareness accuracy is improved, but information processing requirements and system complexity increase
Solution Approach 1:
The system employs multi-functional sensors and processing components that simultaneously perform multiple tasks: capturing spatial data, recognizing worksite features, tracking shovel position, and updating the virtual environment. This universality reduces overall system complexity by consolidating functions rather than requiring separate dedicated systems for each function.

AI summary
A construction assist system (SYS) to assist construction with a shovel (100) includes a controller (50) to simulate the motion of the shovel (100) in a virtual environment set based on the work environment of the shovel (100). The controller (50) may perform the simulation based on the output of a space recognition device that recognizes a space around the shovel (100). The space recognition device may be mounted on the shovel (100) or may be installed outside the shovel (100). Furthermore, the construction assist system (SYS) may include a display device (D1) to display the result of the simulation performed by the controller (50).
