Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple cables and connectors are used to interconnect modules on a backplane, then module connectivity and system functionality are achieved, but space utilization becomes inefficient and design complexity increases
Solution Approach 1:
The patent merges multiple interconnection functions into a single integrated midplane structure. The midplane carrier integrates multiple connectors and cable pathways into one unified component that simultaneously connects multiple modules, eliminating the need for separate cables and connectors for each module interconnection.
Solution Approach 2:
The midplane carrier serves multiple functions simultaneously: it acts as a structural support element, an interconnection hub, and a routing pathway for multiple modules. This universal component performs the roles of traditional separate cables and connectors, reducing overall system complexity while maintaining reliable module connectivity.
2Reliability
If multiple cables are used to connect modules on a backplane, then all modules can be interconnected, but space utilization becomes ineffective
Solution Approach 1:
The patent consolidates multiple cable pathways and connector functions into a single integrated midplane structure. This merging eliminates redundant cable routing and connector placements, thereby improving space utilization while maintaining complete module interconnection capability.
3Stability of the object's composition
If modules are fixed attached to the backplane, then stable connections are achieved, but alignment precision and ease of installation are reduced
Solution Approach 1:
The patent introduces a dynamic alignment mechanism where the midplane carrier can float or move within defined boundaries during module installation. This dynamic capability allows the midplane to self-align with modules, achieving precise alignment without requiring complex fixed attachment mechanisms that would compromise installation ease.
4Reliability
If a traditional backplane with multiple connectors is used, then module connectivity is achieved, but manufacturing cost increases
Solution Approach 1:
The patent reduces manufacturing cost by merging multiple separate connectors and cable assemblies into a single midplane carrier component. This consolidation reduces the number of parts that need to be manufactured, assembled, and quality-checked, thereby lowering overall manufacturing costs while maintaining reliable module connectivity.
Solution Approach 2:
The midplane carrier serves as a universal interconnection solution that replaces multiple specialized connectors and cable types. This universality simplifies the manufacturing process by using standardized components and assembly procedures, reducing manufacturing complexity and cost while achieving the required module connectivity.
