Fan Frame Snap-Fit Light Guide Mounting Without Screw Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fans with light sources often require screw holes for light guide components, which compromise the appearance and lead to light leakage and inconvenient assembly.
Innovation Solution
A fan design featuring a frame body without screw holes, utilizing extending bases and posts for mounting light guide components, ensuring the light guide components are securely attached without compromising the fan's appearance and assembly convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw holes are used to fix light guide components on the fan frame, then the assembly is secure, but the appearance is compromised and light leakage occurs
Solution Approach 1:
The patent removes the screw holes from the fan frame by extracting the traditional screw fixation method. Instead, it uses a snap-fit structure where the light guide component has protrusions that engage with corresponding recesses on the fan frame, eliminating the need for holes that compromise appearance and cause light leakage.
Solution Approach 2:
The patent introduces an intermediary snap-fit mechanism consisting of protrusions and recesses that mediate between the light guide component and the fan frame. This intermediary structure provides secure fixation without requiring screw holes, thus maintaining appearance quality and preventing light leakage.
2Reliability
If screw holes are made on the fan frame for light guide components, then the assembly is secure, but light leakage occurs
Solution Approach 1:
The patent extracts the harmful screw holes from the fan frame design. By replacing the screw fixation method with a snap-fit structure using protrusions and recesses, it eliminates the holes that allow light to leak through while maintaining secure fixation of the light guide component.
3Reliability
If traditional screwing manner is used to fix light guide ring, then the fixation is reliable, but the assembly convenience is reduced
Solution Approach 1:
The patent replaces the mechanical screw fixation system with a simpler snap-fit mechanism. The light guide component features protrusions that automatically engage with recesses on the fan frame during assembly, eliminating the need for screws, hole alignment, and threading operations, thus significantly improving assembly convenience while maintaining fixation reliability.

AI summary
A fan including fan frame, fan rotor, at least one light source and first light guide component. Fan frame includes frame body and first assembling structures. Frame body includes outer and inner walls. First assembling structures each comprise extending base and post. Extending base protrudes from outer wall, a part of extending base is spaced apart from outer wall so that a gap is formed therebetween, and post protrudes from a side of extending base located away from outer wall. Light source is disposed on fan frame. First light guide component is engaged with fan frame. A light emitted from light source is configured to be incident on first light guide component. First light guide component includes first wall and second assembling structures. Second assembling structures are connected to first wall and respectively and removably mounted on first assembling structures.
