1Productivity

If multiple computing devices are integrated into a predetermined area to provide more computational resources, then productivity increases, but electromagnetic interference between devices worsens

Engineering Contradiction:

Improvecomputational resourcesVSAvoidelectromagnetic interference

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The housing device is divided into multiple separate compartments, each capable of containing individual computing devices. This segmentation physically isolates EMI-emitting devices from sensitive devices while maintaining integration within a single housing structure, resolving the contradiction between high-density integration and EMI management.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces EMI shielding materials and filtering mechanisms as intermediaries between EMI-emitting devices and sensitive devices. These intermediaries allow computational resources to be densely integrated while actively managing and reducing electromagnetic interference through shielding and filtering.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If EMI isolation enclosures are made structurally robust to prevent deformation, then EMI isolation effectiveness improves, but device access and thermal management become more difficult

Engineering Contradiction:

ImproveEMI isolation effectivenessVSAvoiddevice access

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The housing device incorporates removable panels, doors, or access points that allow the enclosure to transition between sealed (for EMI isolation) and open (for device access) states. This dynamic design maintains EMI isolation effectiveness when closed while enabling easy device access and thermal management when opened.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The housing device applies EMI shielding materials and sealing measures selectively at critical locations where EMI protection is most needed, rather than uniformly throughout the entire structure. This localized approach maintains EMI isolation effectiveness while reducing overall structural complexity and improving accessibility.

Inventive Principle:

Principle #3Local quality

3Reliability

If EMI isolation enclosures are made structurally robust to prevent deformation, then EMI isolation effectiveness improves, but the enclosure complexity increases

Engineering Contradiction:

ImproveEMI isolation effectivenessVSAvoidenclosure structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines EMI shielding functions with the existing structural frame of the housing device, rather than adding separate complex isolation structures. By integrating EMI management into the primary structural elements, the design achieves reliable EMI isolation without significantly increasing overall enclosure complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The housing device uses material property changes (such as incorporating conductive shielding materials or applying coatings) to existing structural elements to achieve EMI isolation, rather than designing entirely new complex structural features. This approach maintains structural simplicity while improving EMI protection effectiveness.

Inventive Principle:

Principle #35Parameter changes
