Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional heat-dissipating fans face issues with wire fixation, as existing methods fail to securely attach wires to the base, leading to potential breakage and allow dust or water vapor entry, due to non-adjustable openings and inadequate sealing.

Innovation Solution

A base assembly with a wire-fixing element featuring flexible extending arms and threaded structures that can be buckled into the base, providing adjustable and secure fixation of wires, preventing movement and breakage while sealing the opening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a wire bundle is used to fix the wire, then the wire can be held in place, but the opening cannot be adjusted according to wire dimension or number, resulting in ineffective fixation

Engineering Contradiction:

Improvewire fixation reliabilityVSAvoidopening adjustability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The wire fixing element incorporates flexible arms that can dynamically adjust their position and shape to accommodate different wire configurations and opening sizes, transforming a static structure into an adaptive one that maintains reliable fixation across varying conditions

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The fixing element allows adjustment of geometric parameters such as arm curvature and positioning to match different wire dimensions and opening sizes, enabling the same structure to effectively secure various wire configurations through parameter modification rather than requiring multiple fixed-size components

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If the opening is not properly blocked, then the structure remains simple, but dust or water vapor can enter the pillow, causing harmful effects

Engineering Contradiction:

Improveblocking structure complexityVSAvoiddust and water vapor intrusion

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The wire fixing element serves multiple functions simultaneously: it secures the wire in place while also acting as a blocking structure to prevent dust and water vapor entry, eliminating the need for separate components and maintaining structural simplicity while providing comprehensive protection

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Strength

If the wire is not securely fixed, then the structure remains simple, but the wire may break when stretched with external force

Engineering Contradiction:

Improvewire fixation strengthVSAvoidfixation structure complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The fixing element uses flexible arms that can deform and conform to the wire and opening geometry, providing strong mechanical anchoring through flexibility rather than rigid constraints, thereby achieving high fixation strength with a relatively simple and adaptable structure

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

A wire-fixing element is coupled into an opening of a base. A wire passes through the opening, and one part of the wire is disposed in the base. The wire-fixing element includes a first end and a second end. A pair of arms is disposed at the first end and the arms are buckled into the opening. A supporting member is disposed at the second end and is used for supporting the wire.
