Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual configuration and provisioning of test benches is used, then flexibility in configuring specific hardware components is maintained, but time consumption and operational burden increase significantly
Solution Approach 1:
The system enables self-service through automated test bench provisioning where the platform automatically configures hardware and software resources based on test requirements without manual intervention. The automated system provisions test benches by selecting available hardware components, configuring software environments, and establishing connections based on stored test case specifications.
Solution Approach 2:
Manual mechanical configuration operations are replaced with automated computational processes. The system uses software-based automation to provision hardware resources, configure test environments, and manage connections instead of manual physical setup, thereby reducing time consumption while maintaining configuration flexibility.
2Reliability
If physical testing facilities with fixed hardware resources are used, then hardware availability is ensured, but geographical restrictions and access complexity increase
Solution Approach 1:
The system creates virtual copies of physical hardware resources through software emulation and virtualization. Instead of requiring physical access to specific testing facilities, users can access virtualized hardware resources remotely through the platform, eliminating geographical restrictions while maintaining hardware availability through virtual instances of required components.
Solution Approach 2:
The system transitions from physical, geographical constraints to a virtual, network-based dimension. Hardware resources are accessed through a centralized platform that provides remote access via network connections, transforming the access model from physical presence requirements to digital connectivity, thereby reducing access complexity.
3Productivity
If limited hardware resources are deployed in testing facilities, then facility resource utilization is maximized, but adaptability to different vehicle variants and test requirements decreases
Solution Approach 1:
The system implements dynamic resource allocation where hardware and software resources are dynamically assigned based on real-time test requirements. Instead of fixed facility configurations, the platform can dynamically provision different hardware combinations, software environments, and test configurations to match various vehicle variants and test cases, maintaining high resource utilization while enhancing adaptability.
Solution Approach 2:
The platform provides universal access to diverse hardware and software resources through a unified virtualized environment. A single platform can support multiple vehicle variants, test types, and hardware configurations simultaneously, allowing one system to serve multiple functions and adapt to different test requirements without requiring separate dedicated facilities for each variant.
4Ease of operation
If manual management of test benches is used, then detailed control over test configurations is maintained, but operational burden and coordination complexity increase
Solution Approach 1:
The system implements automated feedback loops that monitor test bench status, resource availability, and test progress. This feedback enables the automated provisioning system to adjust configurations in real-time, manage resource allocations dynamically, and coordinate multiple test components automatically, reducing management complexity while maintaining detailed control through automated decision-making based on feedback information.
