Conductive Isolator for Electronic Device Shock Attenuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device isolation systems that provide shock and vibration attenuation often require conductive paths that extend outside the device's perimeter, increasing size and vulnerability to electrical shorts or damage, making them unsuitable for confined spaces or heavy applications.
Innovation Solution
An isolation system with a flexible conductor and an electrically conductive isolator, such as a bobbin with an elastomeric bushing, that provides an electrical path between the device and the structure while being integrated within the mount, reducing the overall size and enhancing weight capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductors extend outside the outer perimeter of the electronic device to provide electrical connection, then electrical path is established, but device size increases and vulnerability to electrical shorts increases
Solution Approach 1:
The isolator is designed to perform multiple functions simultaneously: mechanical isolation (shock and vibration attenuation), electrical connection (providing ground path and DC bond), and structural support. By merging these functions into a single integrated component, the need for separate external conductors is eliminated, reducing device assembly size while maintaining electrical connection reliability
Solution Approach 2:
The isolator serves as a multi-functional component that combines vibration isolation, electrical conduction, and mechanical mounting capabilities. This universal component replaces the need for separate isolation elements and external conductors, thereby reducing the overall device footprint and eliminating the vulnerability of exposed external conductors
2Reliability
If conductors extend outside the outer perimeter of the mount, then electrical connection is provided, but conductors may electrically short or be damaged from contact with neighboring objects
Solution Approach 1:
The isolator integrates the electrical conduction function within its structure, eliminating the need for separate external conductors that could expose vulnerable points. The electrical path is contained within the isolator body, protecting it from contact with neighboring objects while maintaining reliable electrical connection
Solution Approach 2:
The isolator acts as an intermediary component that provides electrical connection through its internal structure rather than through exposed external conductors. This intermediate design protects the electrical path from harmful external factors such as contact with neighboring objects
3Reliability
If traditional isolation systems are used, then shock and vibration attenuation is achieved, but device size increases and weight capacity is limited
Solution Approach 1:
The isolator combines mechanical isolation functionality with electrical connection capabilities in a single integrated component. This eliminates the need for separate isolation elements and external conductors, reducing device assembly size while maintaining effective shock and vibration attenuation
Solution Approach 2:
The isolator utilizes composite material construction that provides both mechanical isolation properties and electrical conductivity. This composite approach allows the single component to achieve vibration attenuation performance while maintaining electrical connection, eliminating the need for additional components that would increase device size
