Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light-emitting heat-dissipating fans are limited in the number of light-emitting elements they can accommodate and require additional components for circuit board fixation, and their halos are monotonous, making them costly and structurally complex to achieve color-changing effects.
Innovation Solution
A ring-shaped light-emitting heat-dissipating fan with a flat upper top surface for direct placement of a ring-shaped circuit board, eliminating the need for additional fixation components, and featuring a ring-shaped light guide with a lateral hole for enhanced light emission, allowing customizable light-emitting element placement and color control to create a colorful, variable halo.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If light-emitting elements are received in receiving recesses or holes of the heat-dissipating fan, then the light-emitting elements are fixed in position, but the quantity of light-emitting elements is limited and the structural design becomes complex
Solution Approach 1:
The patent extracts the light-emitting elements from the heat-dissipating fan structure itself and places them on a separate circuit board. This separation removes the constraint of receiving recesses in the fan, allowing unlimited quantity of light-emitting elements to be arranged on the circuit board without complicating the fan's structural design.
Solution Approach 2:
The patent segments the system into two independent parts: the heat-dissipating fan and the light-emitting circuit board assembly. This segmentation allows the light-emitting elements to be freely arranged on the circuit board while the fan maintains its simple original structure, resolving the contradiction between quantity and structural complexity.
2Reliability
If additional components are added to fix the ring-shaped circuit board to the ring-shaped light guide, then the circuit board is securely fixed, but the structural design becomes more complex
Solution Approach 1:
The patent merges the fixation function into the circuit board's own structure by designing recesses directly on the circuit board that engage with protrusions on the light guide. This integration eliminates the need for separate fixation components, achieving reliable fixation while maintaining simple structural design.
Solution Approach 2:
The circuit board performs its own fixation function through its built-in recesses that mate with the light guide's protrusions. The circuit board is self-fixing without requiring additional components, thereby achieving reliable fixation while keeping the overall structure simple.
3Adaptability or versatility
If light guide tubes are used to scatter light from light-emitting elements, then a halo effect is generated, but the halo is monotonous and requires many light-emitting elements to achieve color-changing effects
Solution Approach 1:
The patent uses a ring-shaped light guide instead of traditional light guide tubes, fundamentally changing the light distribution parameter. The ring-shaped geometry enables light to be distributed in a circular pattern, creating a versatile halo effect that can display various colors and patterns with fewer light-emitting elements arranged annularly on the circuit board.

AI summary
A ring-shaped light-emitting heat-dissipating fan comprises a base having a ring-shaped frame and a pivot portion; a fan pivotally disposed at the pivot portion; a ring-shaped light guide having an upper top surface, a lower top surface, an inner lateral surface, and an outer lateral surface; a lid disposed on the ring-shaped frame, with the ring-shaped light guide disposed between the base and the lid, and a receiving space formed between the lid and the ring-shaped light guide; and a ring-shaped circuit board disposed on an upper top surface of the ring-shaped light guide in the receiving space and having thereon a plurality of light-emitting elements arranged annularly. Therefore, the ring-shaped flat region dispenses with any receiving recesses for receiving the light-emitting elements. The ring-shaped circuit board controls color of light emitted from the light-emitting elements and their light emission cycles.
