Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat-dissipating fan designs face a trade-off between operation efficiency and noise reduction, where high efficiency is often accompanied by loud noise, and low noise results in insufficient heat dissipation.
Innovation Solution
The apparatus incorporates a fan component, a Helmholtz resonator, and a speaker component, where the resonator is designed to reduce noise generated by the fan's operation and function as a cabinet for the speaker, amplifying sound frequencies to enhance acoustic quality while maintaining heat dissipation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the heat-dissipating fan operates on a high rotation mode, then the operation efficiency for heat dissipation is significant, but the operation noise is loud
Solution Approach 1:
The patent converts the harmful noise generated by the high-speed fan into a useful function by using it to drive the resonator. The fan-induced air flow activates the resonator to produce audible sound waves, transforming the harmful noise into a beneficial acoustic output for the speaker component.
Solution Approach 2:
The resonator acts as an intermediary between the fan and the speaker component. It receives mechanical energy from the fan's air flow and converts it into acoustic energy, mediating the energy transfer and enabling the speaker to function without direct electrical connection.
2Object-generated harmful factors
If the heat-dissipating fan operates on a low rotation mode, then the operation noise is quite, but the operation efficiency is insignificant
Solution Approach 1:
The system dynamically adjusts the fan's rotation speed based on operational requirements. The fan can operate at different speeds, and the resonator responds accordingly, allowing the system to optimize between heat dissipation efficiency and noise levels depending on the device's thermal and acoustic needs.
Solution Approach 2:
The patent changes the operational parameters of the fan (rotation speed) to achieve different performance levels. By adjusting the fan speed parameter, the system can balance heat dissipation efficiency and noise generation, with the resonator adapting its acoustic output accordingly.
3Object-generated harmful factors
If a resonator is added to reduce fan noise, then the acoustic quality is improved, but the device complexity increases
Solution Approach 1:
The resonator serves multiple functions simultaneously: it acts as a noise reduction element by filtering fan-generated noise, functions as a speaker component to produce audible sound, and serves as part of the acoustic chamber structure. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity.
Solution Approach 2:
The patent merges the resonator with the speaker component and the acoustic chamber structure. By combining these elements into a single integrated component, the design reduces the number of separate parts and simplifies the overall device structure while achieving noise reduction and acoustic output functions.
