Supercap Slave Communication Chain for Simpler Data Collection

Solution Overview

Problem

In supercap systems, the increased number of parts connected in series leads to system weight issues and complex communication connections, which complicates data collection and transmission between slave units and the master unit, necessitating a solution to simplify the circuit and enhance stability.

Innovation Solution

A system where the last slave unit in a series connects to the master unit, allowing it to collect and transmit sensing data from other slave units, thereby simplifying the communication circuit and reducing the number of components, and enabling voltage and temperature monitoring for balanced charging and discharging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If multiple slave units are connected in series to the master unit for data collection, then the sensing data coverage is improved, but the system weight increases and the communication circuit becomes complex

Engineering Contradiction:

Improvesensing data collectionVSAvoidcommunication connection

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The system segments the data collection function by dividing slave units into different groups (first group connected to master, second group connected to first group). This segmentation allows distributed sensing while maintaining a hierarchical structure that simplifies overall system complexity compared to fully distributed connections.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first slave unit acts as an intermediary between the second slave unit and the master unit. It collects sensing data from both itself and the second slave unit, then transmits combined data to the master unit. This intermediary approach reduces the number of direct communication connections needed while ensuring comprehensive data collection.

Inventive Principle:

Principle #24Intermediary (Mediator)
