Adapter Assembly Sealing Rings for Harsh Environment Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic assemblies fail to provide effective protection against dust, moisture, and electromagnetic interference (EMC) in harsh environments such as outdoor facilities and high-voltage systems, while also lacking flexibility for series connections.
Innovation Solution
The design incorporates two adapter arrangements with sealing rings arranged one behind the other, made from different materials for enhanced protection, and a rotatable bracket for secure fastening, along with internal seals to prevent dust, moisture, and EMC ingress, allowing for flexible and secure series connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a single sealing ring is used in the adapter housing, then the structure is simple, but the protection against dust, moisture, and EMC is insufficient
Solution Approach 1:
The sealing function is segmented into multiple independent sealing rings arranged in series within the adapter housing. Each sealing ring addresses specific protection requirements (dust, moisture, EMC), allowing the system to achieve comprehensive protection while maintaining modular simplicity
Solution Approach 2:
Different sealing rings are made from different materials optimized for different protection functions. One sealing ring may use material optimized for dust and moisture sealing, while another uses material optimized for EMC shielding, creating a composite sealing system that addresses multiple harmful factors simultaneously
2Adaptability or versatility
If adapter housings are connected in series, then flexibility and expandability are improved, but the risk of dust, moisture, and EMC ingress at connection points increases
Solution Approach 1:
The adapter housings are designed to nest within each other through recesses and protrusions, creating an interlocked configuration. The sealing rings are positioned within these nested interfaces to ensure continuous sealing protection even when multiple adapter housings are connected in series
Solution Approach 2:
The sealing rings are pre-installed and positioned within the adapter housing before connection. The fastening elements are pre-configured to automatically engage and compress the sealing rings when adapter housings are connected, ensuring protection is established before any potential ingress can occur
3Reliability
If the bracket is fixed in position, then the fastening is simple, but the ability to lock securely to the web is reduced
Solution Approach 1:
The bracket is designed with rotational movement capability, transitioning from a basic position to a locked position where it engages with the web. This dynamic adjustment allows the bracket to adapt to the connection interface and achieve secure locking through rotational engagement rather than requiring complex multi-component fastening mechanisms
