Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional manufacturing processes are used for electric vehicle assembly, then the process can be completed with existing equipment and methods, but the cycle time is increased and manufacturing efficiency is reduced
Solution Approach 1:
The system performs preliminary analysis of ergonomic constraints, part dimensions, and assembly requirements before generating the assembly sequence. By pre-processing this data and using machine learning models to predict optimal sequences in advance, the system minimizes cycle time during actual manufacturing while maintaining high productivity.
2Ease of operation
If traditional assembly sequencing is used, then the process is simple to implement, but ergonomic constraints are not adequately considered leading to potential health risks for workers
Solution Approach 1:
The system introduces an intermediary AI model that acts as a mediator between the assembly requirements and the sequencing decisions. This intermediary layer processes ergonomic data, part dimensions, and constraints to generate optimized sequences, protecting workers from ergonomic hazards while managing system complexity through modular architecture.
3Area of stationary object
If manual planning of assembly sequences is used, then the process is flexible to accommodate changes, but the space utilization and station placement are suboptimal
Solution Approach 1:
The system dynamically generates assembly sequences and station placements based on input data including part dimensions, ergonomic constraints, and manufacturing requirements. The machine learning model can adapt to different products and constraints by reprocessing input data, optimizing space utilization while maintaining flexibility through data-driven decision-making rather than fixed manual planning.
4Productivity
If assembly sequences are generated without considering part dimensions and ergonomics, then the planning process is faster, but the resulting sequences lead to increased cycle times and potential worker injury
Solution Approach 1:
The system performs preliminary analysis of ergonomic constraints and part dimensions before generating assembly sequences. By pre-processing this data and using machine learning models to predict optimal sequences that account for worker safety, the system achieves both high assembly speed and worker health protection without compromising either aspect.

AI summary
The present solution provides a model for manufacturing products, such as electric vehicles. The solution can use a data processing system to receive data identifying physical characteristics of a part of a plurality of parts of a product to assemble. Data processing system can identify a first constraint corresponding to ergonomic data for assembling the part. Data processing system can identify a second constraint corresponding to the physical characteristics of the part. Data processing system can generate, using the data input into a model of the data processing system and based on the first constraint and the second constraint, a sequence identifying an order in which to assemble the part into the product with respect to assembly of the plurality of parts.
