Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric power plugs lack protection mechanisms, leading to potential electric shocks, wire fires, and power disconnection issues due to loose connections and pressure failures, which can result in dangerous electrical accidents.
Innovation Solution
The design incorporates a replaceable fuse and a tight pressure mechanism with zigzag tooth-wise patterns on contraction plates to secure the electric power line, along with a backup fuse system for easy replacement, ensuring secure connections and preventing power line disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pressure-connection installations are used to join electric power lines in conventional plugs, then the plug structure is simple and easy to manufacture, but the connection becomes loose or deviated after long-term use due to external force, causing power disconnection or leakage
Solution Approach 1:
The plug structure employs a dynamic tightening mechanism where the tightening component can move between a first position (for initial insertion) and a second position (for secure locking). This dynamic adjustment allows the connection to adapt to external forces over time, maintaining reliability without requiring an overly complex static structure.
Solution Approach 2:
The plug is divided into functional modules: a housing, a tightening component, a connection component, and a sealing component. This segmentation allows each part to perform its specific function independently, improving overall connection stability while keeping the overall structure manageable and manufacturable.
2Object-affected harmful factors
If conventional plugs without protection structures are used, then the plug structure is simple, but electric current overflow may damage appliances or cause wire fires
Solution Approach 1:
The fuse is pre-installed within the housing before the plug is put into service. This preliminary protective measure ensures that if electric current overflow occurs, the fuse will blow to prevent damage to appliances or wire fires, without requiring complex protection systems to be assembled at the time of use.
Solution Approach 2:
The fuse acts as an intermediary protective element between the electric power line and the connected appliances. It provides overcurrent protection by interrupting the circuit when excessive current flows, thereby protecting both the plug structure and the connected devices without adding complex control systems.
3Reliability
If a tight pressure mechanism with zigzag tooth-wise patterns is added to secure the electric power line, then power line disconnection is prevented, but the manufacturing complexity increases
Solution Approach 1:
The tightening component integrates multiple functions into a single element: it provides mechanical clamping through zigzag tooth-wise patterns, maintains electrical contact through the connection component, and ensures sealing through the sealing component. This merging reduces the number of separate parts and simplifies the manufacturing process while achieving reliable power line security.
Solution Approach 2:
The zigzag tooth-wise pattern on the tightening component creates variable contact points that adapt to the diameter and shape of the electric power line. This parameter variation allows the same component to securely hold different types of power lines without requiring custom-designed parts for each application, easing manufacturing.
4Ease of operation
If a replaceable fuse system is implemented, then fuse replacement becomes convenient for users, but the plug structure becomes more complex
Solution Approach 1:
The fuse is designed as a separate, extractable component that can be removed and replaced independently from the main plug body. This extraction design allows users to conveniently replace fuses without disassembling the entire plug, improving ease of operation while keeping the overall structure relatively simple through modular design.

AI summary
A plug structure comprises a seat body, an electric power line and a housing, wherein the front end of the seat body includes at least two conductive plates, the inside of the seat body has a main fuse electrically connected to the conduct plate and a backup fuse, and the electric power line can be set up at the rear end of the seat body and clipped by the contraction plates respectively installed on the two sides of the rear end of the seat body; therefore, when the housing is sleeve installed towards the seat body from the electric power line, the contraction plate squeezes the electric power line due to the structure at the rear end of the housing such that the zigzag tooth-wise pattern configured on the inner surface of the contraction plate can tightly press upon the surface of the electric power line so the electric power line may not be easily pulled out from the rear end of the seat body.
