Vertical Solarium Fan Relocation for Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vertical tanning devices often suffer from high noise levels and the risk of catching a cold due to inefficient air circulation, which is unpleasant and uncomfortable, especially in cold weather.
Innovation Solution
A vertical tanning device design featuring a large central opening at the top for fresh and cooling air intake, with air flowing around the user and exiting through openings at the foot area to cool the lamps, using a radial fan positioned outside the head area to minimize noise and discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a motor-driven axial fan is installed in the head area to cool the tanning lamps, then the cooling effect is achieved, but high noise levels and risk of catching a cold occur
Solution Approach 1:
The fan is extracted from the head area and repositioned to the foot area of the tanning device. This relocation removes the noise source from the user's head region while maintaining the cooling function through the airflow path that rises from the foot area through the walls to cool the lamps.
Solution Approach 2:
Instead of introducing cooling air from the top and exhausting from the bottom, the system inverts the airflow direction by introducing air from the foot area and exhausting from the head area. This reversal of the conventional airflow pattern resolves the contradiction by positioning the fan away from the user's head while maintaining effective cooling.
2Temperature
If cooling air is blown in from below using a blower, then the tanning lamps are cooled, but the user may freeze in cold weather
Solution Approach 1:
The system incorporates dynamic control of the fan speed based on temperature sensors that monitor both the lamp temperature and ambient conditions. The fan speed is adjusted in real-time to provide sufficient cooling for the lamps while preventing the user from freezing in cold weather, resolving the contradiction through adaptive regulation.
3Temperature
If individual wall parts have their own ventilation fans, then each section is cooled independently, but the construction becomes complex
Solution Approach 1:
Multiple ventilation functions are merged into a single fan system located in the foot area. This unified approach eliminates the need for separate fans in each wall section while achieving coordinated cooling through the shared airflow path that rises through the walls, thereby reducing construction complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design provides a more pleasant air flow experience, reduces noise exposure, and allows for adjustable air consumption based on temperature, ensuring the user is not exposed to cold air initially, with the fan starting only when necessary to maintain optimal cooling.
Implementation Method 1
a radial fan for moving cooling air, which acts on the tanning lamps and the user in the interior
Implementation Method 2
leaves the interior through at least one opening located in the foot area and flows upwards through the spaces provided in the walls of the fixed part
Implementation Method 3
cooling air, which acts on the tanning lamps and the user in the interior
