Cooling Fan Motor Layout With Integrated Nixie Speed Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooling fans lack intuitive display of rotation direction and speed, leading to deficiencies in user understanding and visual appeal.
Innovation Solution
A cooling fan design incorporating a nixie tube with a PCB board and stator part, where a pin of the nixie tube passes through the stator part to connect electrically with the PCB board, allowing data display via the nixie tube, and a light-transmitting member for protection and clarity, along with a controller for control and shock-absorbing pads for noise reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a nixie tube is added to the driving unit for data display, then the visual effect and data display capability are improved, but the device complexity increases
Solution Approach 1:
The patent merges the nixie tube display component with the driving unit by having the nixie tube pin pass through the stator part to connect with the PCB board. This integration allows the display function to be incorporated into the existing motor structure without requiring a completely separate display system, thus improving visual effect while controlling complexity growth.
Solution Approach 2:
The driving unit is designed to serve multiple functions: it provides motor drive capability (stator and rotor parts) and simultaneously serves as a mounting structure for the nixie tube display. The stator part acts both as a motor component and as a structural element that accommodates the display, making the driving unit a multi-functional component that addresses both motion generation and information display needs.
2Device complexity
If the nixie tube pin passes through the stator part to connect with the PCB board, then the structure is simplified, but the manufacturing precision requirements increase
Solution Approach 1:
The design segments the connection path into distinct sections: the nixie tube pin passes through the stator part (which has a predefined spacing) to reach the PCB board. This segmentation allows each component to be manufactured and assembled separately with standard tolerances, rather than requiring a single complex integrated structure, thus simplifying the overall structure while managing manufacturing precision requirements through modular assembly.
3Object-generated harmful factors
If shock absorbing pads are added to the outer frame, then the noise reduction is improved, but the device complexity increases
Solution Approach 1:
The shock absorbing pads are simple, inexpensive components that can be easily added to the outer frame corners. These pads are basic vibration damping elements that provide effective noise and vibration reduction without requiring complex mechanisms. Their simplicity and low cost allow them to be integrated into the frame structure with minimal impact on overall device complexity while effectively addressing the noise issue.
