Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of stationary object

If a large or very large scale electromagnetically shielded enclosure is needed, then the enclosure size increases, but radiofrequency leakage at seams and ingress/egress points worsens

Engineering Contradiction:

Improveenclosure sizeVSAvoidradiofrequency leakage

Core Design Contradiction:

Volume of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The enclosure is divided into multiple modular sections that can be assembled together. Each module has standardized interfaces with electromagnetic seals, allowing large enclosures to be constructed from smaller shielded units, maintaining shielding effectiveness while achieving large overall size.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Electromagnetic seals and gaskets are introduced as intermediary elements at all接缝 and ingress/egress points. These specialized sealing components bridge the gaps between modular sections and at access points, preventing radiofrequency leakage while allowing mechanical connection and access functionality.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If a modular electromagnetically shielded enclosure is designed, then reconfigurability and adaptability improve, but construction complexity increases

Engineering Contradiction:

ImprovereconfigurabilityVSAvoidconstruction complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The enclosure is divided into standardized modular sections with uniform connection interfaces. This segmentation allows different configurations to be assembled from the same set of modules, improving reconfigurability while keeping individual module complexity manageable through standardization.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The modular sections are designed with universal connection interfaces and standardized electromagnetic seals that can be used in any configuration. This universality allows the same components to serve multiple functions in different arrangements, improving adaptability without proportionally increasing construction complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Object-affected harmful factors

If electromagnetic shielding effectiveness is enhanced, then radiofrequency leakage reduces, but weight and cost increase

Engineering Contradiction:

Improveradiofrequency leakageVSAvoidenclosure weight

Core Design Contradiction:

Object-affected harmful factorsVSWeight of moving object

Solution Approach 1:

Electromagnetic seals and gaskets serve as intermediary components that provide the necessary shielding at critical interfaces without requiring the entire enclosure structure to be heavily shielded. This localized approach to shielding reduces overall weight while maintaining effectiveness at接缝 and access points.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Electromagnetic shielding is applied with varying intensity at different locations - heavy shielding at critical ingress/egress points and接缝 where leakage occurs, and lighter shielding in other areas. This localized quality approach optimizes shielding effectiveness while minimizing unnecessary weight.

Inventive Principle:

Principle #3Local quality

AI summary

A modular electromagnetically shielded enclosure is provided. The enclosure includes connective frame elements that make up a support frame assembly. Conductive fabric panels are fastened to the connective frame elements to form walls and ceiling. A modular electromagnetically shielded floor assembly is made up of floor panels with rabbet edges that form channels for the placement of electromagnetic shielding gaskets and floor panel connectors. The conductive fabric panels that make up the walls of the enclosure are fastened to the modular electromagnetically shielded floor assembly to form a faraday cage environment that can be readily assembled to create a large or very large shielded enclosure and that can be reconfigured with continued radiofrequency shielding effectiveness.
