Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual entry methods are used to store datacenter rack content information, then the system is simple to operate, but the accuracy of rack content information deteriorates
Solution Approach 1:
The system enables self-service by allowing the datacenter environment to be automatically imaged and documented without human intervention. The AGV autonomously navigates, captures images, and the system automatically processes this data to update inventory records, eliminating the need for manual entry while maintaining simplicity of operation.
Solution Approach 2:
Manual mechanical entry methods are replaced with an automated optical imaging system. The system uses cameras to capture images, processes them through image recognition algorithms, and automatically updates inventory databases, substituting human manual operations with automated mechanical and computational systems.
2Reliability
If conventional imaging systems with overlapping fields of view are used, then complete coverage is achieved, but the complexity of processing and correlating images increases
Solution Approach 1:
The datacenter environment is divided into multiple discrete zones, each captured by a dedicated camera with a non-overlapping field of view. This segmentation approach simplifies processing by assigning each image to a specific spatial region, eliminating the need for complex overlapping image correlation while ensuring complete coverage through systematic zone-by-zone mapping.
3Productivity
If automated guided vehicles with multiple cameras and laser systems are deployed, then imaging precision and coverage improve, but the cost and complexity of the system increase
Solution Approach 1:
The AGV is designed as a universal platform that performs multiple functions: navigation via laser imaging, datacenter mapping, rack content imaging, and autonomous return to base. By consolidating these diverse functions into a single multi-functional vehicle, the system achieves high productivity without proportionally increasing complexity, as the same hardware platform executes multiple tasks.
