Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In power supply systems where multiple loads are connected, overloads can occur due to varying working conditions, leading to increased temperatures and potential mainboard failure, fires, and security incidents.
Innovation Solution
An electric connection assembly comprising a connector, wires, and a fuse, where the fuse is connected in series with one of the wires to prevent overload-induced temperature rises, featuring a protective sleeve for the fuse to ensure safety and ease of replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple loads are connected through a single mainboard to a power supply system, then the power supply system can simultaneously supply power to multiple loads, but an overload in one load can cause temperature rise and lead to mainboard failure and security incidents
Solution Approach 1:
The patent divides the power connection system into independent modular units, each with its own connector and fuse. Instead of one centralized mainboard connection for multiple loads, each load has its own connection assembly with independent overload protection, segmenting the risk so that one overload does not affect other loads
Solution Approach 2:
The fuse acts as an intermediary protective element inserted between the power supply and the load. It mediates the electrical connection by providing a sacrificial component that breaks the circuit under overload conditions, protecting the mainboard and other components from damage
2Reliability
If a fuse is added in series with the wire to prevent overload, then the system safety is improved, but the device complexity increases
Solution Approach 1:
The patent combines the connector and fuse into a single integrated connection assembly. The fuse is built into the connector structure itself, merging two components into one unified unit that provides both electrical connection and overload protection functions simultaneously
Solution Approach 2:
The connection assembly is designed to be self-protecting through the integrated fuse that automatically responds to overload conditions without external intervention. The fuse element self-destructs to break the circuit when excessive current is detected, providing automatic protection
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents overheating and potential fires by breaking the circuit when an overload is detected, ensuring the safety and reliability of the load system.
Implementation Method 1
an overload may occur in one of the plurality of separate loads. An overload in one load raises the temperature of the entire load system

AI summary
An electric connection assembly comprises a connector, a first wire, a second wire, and a fuse. The connector has a housing, a first conductive contact disposed in the housing, and a second conductive contact disposed in the housing. The first wire has a first end electrically connected to the first conductive contact and an opposite second end electrically connected to a first electrode of a load. The second wire has a first end electrically connected to the second conductive contact and an opposite second end electrically connected to a second electrode of the load. The fuse is connected in series with the second wire.
