Solution Overview

Problem

Conventional fans experience reliability issues due to excess wire length causing interference with other components, which compromises the efficient electrical connection to external systems.

Innovation Solution

A fan design featuring a plug with a terminal seat and linking portions connected to a frame, including bipolar knife-shaped terminals, that allows for precise electrical connection and assembly, preventing wire interference by using fixed holes and linking portions to secure the terminal seat within the accommodating portion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wires are configured with predetermined or long length to connect fan to external system, then electrical connection is established, but excess wire length causes interference with other components reducing reliability

Engineering Contradiction:

Improveelectrical connection reliabilityVSAvoidwire interference with components

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent divides the wire connection system into segments: a main wire running through the frame and shorter linking portions connecting to the terminal seat. This segmentation reduces the effective length of wires near components, minimizing interference while maintaining electrical connection reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The terminal seat is nested within the frame structure, with linking portions passing through fixed holes in the frame. This nesting arrangement organizes wires within the frame boundaries, preventing excess wire from interfering with external components while ensuring stable electrical connection.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Productivity

If conventional terminal connection structure is used, then electrical connection is achieved, but assembly process is complex and time-consuming

Engineering Contradiction:

Improveassembly speedVSAvoidconnection structure complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent merges the terminal seat, linking portions, and frame into an integrated structure where the terminal seat is directly mounted on the frame via fixed holes. This combination eliminates separate connection steps and reduces assembly complexity, improving productivity while maintaining connection functionality.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The frame serves multiple functions: it provides structural support, contains fixed holes for mounting the terminal seat, and guides the linking portions. This multi-functionality reduces the need for additional components and simplifies the overall connection structure, enhancing assembly efficiency.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The present invention provides a fan having a frame and a plug. The frame includes an accommodating portion and at least two fixed holes. Each of the fixed holes is disposed on the two sides of the accommodating portion. The plug has a terminal seat with at least two linking portions and a bipolar knife-shaped terminal between an top seat and a bottom seat of the terminal seat, and the plug so that the plug is assembled with the fixed holes of the frame via the linking portions of the plug and is accommodated within the accommodating portion of the frame.
