Sealing Barrier for Containing Electronic Failure Emissions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for detecting electrical failures in electronic equipment often result in loud noises and smoke emissions, which can be startling and lead to unnecessary evacuations, and are prone to false alarms and high costs due to the use of electronic monitoring and sensing schemes.
Innovation Solution
A non-electronic apparatus comprising a conformable pad, gasket, and clip that forms a sealed barrier around electronic devices to contain sound and smoke, allowing for easy assembly and disassembly for servicing, and is designed to be cost-effective and minimize false alarms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If audible alarms are used to alert operators of electrical failure, then failure notification is improved, but noise pollution and operator startle response worsen
Solution Approach 1:
The patent converts the harmful failure noise and smoke into contained, manageable emissions. By using a conformable pad and gasket barrier system, the failure noise and smoke that would normally be harmful are instead contained within a defined space, preventing them from polluting the environment and startling operators, while still allowing visual monitoring of the contained emissions as a failure indicator
2Object-generated harmful factors
If potting material is used to contain devices and assemblies, then smoke and sound emissions are reduced, but device servicing and design changes become difficult
Solution Approach 1:
The patent divides the containment system into separate, modular components: a conformable pad that interfaces with the device surface, a gasket that forms the barrier perimeter, and a clip that provides mechanical attachment. This segmentation allows each component to be independently installed, removed, and replaced, enabling easy device servicing and design changes without requiring complete encapsulation like traditional potting material
Solution Approach 2:
The patent uses a dynamic, flexible containment system rather than a static rigid structure. The conformable pad can adapt to device surface variations, and the clip-gasket assembly can be easily attached and detached. This dynamic design allows the containment barrier to remain in place during operation but be quickly removed for servicing, unlike rigid potting material that requires destruction to access devices
3Reliability
If electronic monitoring circuits are installed to prevent catastrophic failure, then device protection is improved, but system complexity and cost increase
Solution Approach 1:
The patent extracts and removes all electronic monitoring and sensing circuits from the system. Instead of adding complex electronic protection circuits that monitor current, voltage, and drive signals, the invention uses a simple mechanical barrier system that provides passive protection by containing emissions, thereby reducing system complexity while maintaining device protection capability
Solution Approach 2:
The patent employs inexpensive, simple mechanical components (conformable pad, gasket, clip) instead of expensive electronic monitoring circuits. These simple barrier components provide adequate protection by containing emissions, eliminating the need for costly electronic monitoring and sensing schemes while maintaining reliable device protection

AI summary
An apparatus and method are provided for limiting failure noise and smoke emissions produced as a result of electrical failure conditions and/or failed electronic devices or assemblies of electronic equipment, such as IT and telecommunications equipment. In one aspect, the apparatus includes a conformable pad, a gasket and a clip that are disposed along one or more surfaces or planes of one or more electronic devices or assemblies such that the apparatus helps to form a substantially air tight seal around the one or more devices or assemblies. The air tight seal the apparatus defines minimizes or eliminates failure noise and smoke emissions generated as a result of failure conditions or catastrophic failure of the one or more devices or assemblies. The apparatus thereby provides a non-electronic solution to limiting failure noise and smoke that is relatively inexpensive to manufacture and implement, and enables in-field servicing of its components and the devices or assemblies to which it is applied.
