Interchangeable AC Mains Filter for Noise Frequency Targeting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
AC powered devices suffer from performance degradation due to noise on the mains power circuit, and existing power conversion devices are not configurable to select specific noise frequencies, leading to costly replacements when filters fail.
Innovation Solution
A filter system with interchangeable connectors, including a male and female C13/C14 connector configuration, allowing for easy addition and cascading of filters to target specific noise frequencies, thereby improving device performance without requiring entire device replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If filters are built into the system, then noise filtering performance is improved, but device cost and complexity increase
Solution Approach 1:
The filter is separated from the powered device into an independent, removable module that connects via standard AC connectors. This segmentation allows the filter to be added or removed without modifying the device itself, reducing overall system complexity while maintaining noise filtering capability.
Solution Approach 2:
A standard AC power connector serves as an intermediary between the powered device and the removable filter. This intermediary interface enables easy connection and disconnection of the filter without requiring integration into the device's internal circuitry.
2Object-affected harmful factors
If filters are built into the system, then noise filtering performance is improved, but manufacturing cost increases
Solution Approach 1:
By segmenting the filter into a separate removable module, manufacturers can produce filters independently and add them to devices as needed, rather than integrating them into every device. This reduces manufacturing costs for devices that don't require filtering while maintaining the option to add filtering capability.
Solution Approach 2:
The removable filter design allows for cost-effective replacement of filters rather than replacing entire devices. This approach treats the filter as a separate, replaceable component that can be manufactured and replaced at lower cost.
3Object-affected harmful factors
If filters are built into the system, then noise filtering performance is improved, but ease of repair and modification decreases
Solution Approach 1:
The filter is divided into a separate removable module that can be easily detached and replaced. This segmentation enables users to replace a faulty filter by simply unplugging and replugging the connector, without requiring technical expertise or device disassembly.
Solution Approach 2:
The filter connection is designed to be dynamic and changeable rather than fixed. The removable connector allows the filter configuration to be easily modified or replaced based on different noise filtering requirements or device needs.
4Object-affected harmful factors
If multiple filters are cascaded, then noise filtering performance is improved, but device complexity increases
Solution Approach 1:
Multiple filters can be cascaded by connecting them in series through the standard AC connector interface. This merging approach allows comprehensive noise filtering across multiple frequency ranges while maintaining a simple, uniform connection method that doesn't increase system complexity.
