Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If EMI emitting devices are placed in high-density environments with tightly packed devices, then device density and space utilization are improved, but electromagnetic interference propagation increases causing disruption to thermal management, mechanical positioning, and electrical operations
Solution Approach 1:
The device is divided into separate isolated volumes for EMI-emitting devices and non-isolated volumes for other components. This segmentation allows EMI-emitting devices to be packed densely while containing their electromagnetic interference within specific isolated compartments, preventing interference propagation to other devices and systems.
Solution Approach 2:
EMI isolation structures act as intermediary barriers between EMI-emitting devices and other sensitive components. These isolation structures mediate the electromagnetic environment by blocking and containing EMI within isolated volumes, enabling high-density device placement without compromising the operational integrity of adjacent components.
2Object-affected harmful factors
If EMI isolation structures are implemented to contain electromagnetic interference, then EMI propagation is reduced, but device complexity and structural requirements increase
Solution Approach 1:
The EMI isolation structures are designed to perform multiple functions simultaneously: they provide electromagnetic interference containment while also serving as structural mounting frameworks for devices. The isolated volumes and chassis structures fulfill both EMI shielding and mechanical support roles, reducing overall device complexity despite the presence of isolation requirements.
Solution Approach 2:
The EMI isolation structures are merged with the device chassis and mounting framework. Rather than adding separate isolation components, the isolation functionality is integrated into the existing structural elements, such as combining EMI shielding walls with chassis components and mounting structures, thereby reducing overall structural complexity.
3Object-affected harmful factors
If isolated volumes are created for EMI emitting devices, then EMI suppression is achieved by at least 80 decibels, but thermal management challenges increase due to restricted gas flow
Solution Approach 1:
The EMI isolation structures incorporate gas flow passages and openings that maintain electromagnetic isolation while allowing thermal management gas flow. These flexible design elements enable heat dissipation through the isolation walls via controlled gas circulation, resolving the conflict between EMI containment and thermal management.
Solution Approach 2:
Gas flow passages act as intermediaries that transfer thermal energy out of isolated volumes while maintaining EMI containment. The passages allow thermal management gas to circulate through and around EMI-emitting devices, removing heat without compromising the electromagnetic isolation provided by the structured walls and enclosures.
4Ease of operation
If support modules are placed outside isolated volumes to provide power and communication services, then ease of operation is improved, but EMI isolation effectiveness may be compromised
Solution Approach 1:
Support modules providing power, communication, and thermal management services are extracted from isolated volumes and placed in non-isolated areas. This extraction maintains ease of operation and service accessibility while preventing EMI from affecting the support modules. Connection interfaces and feedthroughs provide controlled access points that maintain EMI isolation boundaries.
Solution Approach 2:
Physical connection interfaces and feedthrough structures replace the need for support modules to be physically located inside isolated volumes. These substitution elements provide electrical, communication, and thermal management connections through the isolation barriers, maintaining both EMI isolation effectiveness and service accessibility without requiring internal placement of support equipment.
