Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surge protection systems in split mount wireless radio systems are inadequate in detecting and logging surge events, leading to uncertainties in determining the cause of failures and potential misallocation of repair responsibilities.
Innovation Solution
A signal distribution and protection module (SDPM) that includes an RF path, a DC path inductively coupled to the RF path, and a surge protection and detection component with clamping devices and a surge detector, which logs and records surge events for future reference, using a processor and memory to manage and output this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external surge arrestors are used for ODU protection, then surge protection capability is improved, but device complexity and cost increase due to separate housing requirements
Solution Approach 1:
The patent combines the surge protection function with the existing ODU housing structure by providing surge protection circuits inside the ODU housing. This integration eliminates the need for separate external surge arrestor housings, reducing overall device complexity while maintaining surge protection capability. The surge protection component is merged with the power supply module within the same housing structure.
2Device complexity
If surge protection circuits are integrated inside ODU housing, then device complexity is reduced, but protection effectiveness may be compromised
Solution Approach 1:
The patent implements different levels of surge protection at different locations within the system. Primary surge protection is provided at the power service entrance, while secondary surge protection circuits are integrated inside the ODU housing. This localized quality approach ensures that each component receives appropriate protection based on its vulnerability, maintaining overall protection effectiveness while optimizing device complexity.
3Device complexity
If surge events are not detected and logged, then system simplicity is maintained, but ability to determine failure causes is reduced
Solution Approach 1:
The patent incorporates a surge detection circuit that monitors surge events and provides feedback information about detected surges. The system logs surge event data including timing, magnitude, and characteristics, which is stored and can be retrieved for analysis. This feedback mechanism enables determination of failure causes by providing information about surge events that may have preceded system failures, without significantly increasing overall system complexity.
