Solution Overview
Problem
Conventional power distribution systems require separate circuit failure devices for each load, which can lead to increased complexity and cost, and may not effectively manage failures in systems with loads of varying operating voltages.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate circuit failure devices are used for each load, then system reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines multiple pulse generators into a single shared pulse line that serves multiple loads. Instead of having separate failure protection devices for each load, a single pulse line with shared pulse generators provides protection for all loads collectively, reducing device complexity while maintaining system reliability through redundant pulse generation capability
2Reliability
If separate circuit failure devices are used for each load, then system reliability is improved, but cost increases
Solution Approach 1:
The patent merges multiple pulse generation functions into a shared infrastructure. By having pulse generators that can serve multiple loads through a common pulse line, the system reduces the total number of components needed compared to having separate failure protection devices for each load, thereby reducing manufacturing cost while maintaining reliability
Solution Approach 2:
The pulse generators are designed with multi-functionality to serve multiple loads simultaneously. A single pulse line can distribute pulses to multiple loads, and the pulse generators can adaptively serve different loads based on system conditions, reducing the need for dedicated components for each load and lowering overall system cost
3Device complexity
If pulse generators operate without failure detection, then device complexity is reduced, but system reliability deteriorates
Solution Approach 1:
The patent incorporates failure detection circuits that continuously monitor the operation of pulse generators. When a failure is detected in one pulse generator, the system receives feedback and can switch to using another pulse generator to maintain pulse generation for the loads, thereby improving system reliability without requiring separate protection devices for each load
