Problem
Conventional ventilation fans with integrated lighting modules face challenges in providing sufficient lighting while maintaining ventilation function and accommodating additional function modules, often resulting in a cluttered appearance and noise from the fan module.
Innovation Solution
A borderless lighting ventilation fan design featuring a lateral-suction inlet with a hidden fan module, integrated LED lighting that emits light radially and axially, and a detachable function module such as a Bluetooth speaker, night-light, or humidity sensor, which enhances aesthetics and reduces noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lighting module and additional function module are added on the bottom cover, then the lighting and additional functions are provided, but the appearance becomes cluttered and the inlet ventilation area is reduced
Solution Approach 1:
The device is divided into separate functional modules: the lighting module with axial light emission, the function module (such as Bluetooth speaker or sensor) with radial light emission, and the lateral-suction inlet. This segmentation allows each module to be optimized independently, maintaining a clean appearance while providing multiple functions.
Solution Approach 2:
The lighting module transitions from traditional radial emission to axial emission, changing the dimension of light delivery. This allows the radial inlet area to remain open for ventilation while the lighting function is provided along the axial direction, resolving the conflict between lighting coverage and inlet area.
2Area of stationary object
If the lighting module is integrated on the bottom cover with radial inlet design, then the ventilation function is maintained, but the lighting area is insufficient and the appearance is not smooth
Solution Approach 1:
The lighting module emits light in the axial direction rather than radially, utilizing the vertical dimension for lighting while the horizontal dimension remains dedicated to radial inlet ventilation. This dimensional separation increases lighting area without compromising inlet design.
Solution Approach 2:
The lighting function is extracted from the traditional radial inlet structure and placed in a separate axial-oriented lighting module. This extraction allows the radial inlet to be fully optimized for ventilation while the lighting module provides sufficient lighting area independently.
3Object-generated harmful factors
If the fan module is exposed, then the ventilation function is direct, but the noise is not isolated and the appearance is not aesthetic
Solution Approach 1:
The fan module is nested within the housing structure, which is itself nested within the grille assembly. This nested arrangement allows the fan to be acoustically isolated from the external environment while still maintaining efficient airflow paths for ventilation through the lateral inlet.
Solution Approach 2:
The housing acts as an acoustic shell that encloses the fan module, isolating the noise generated by the fan while allowing the ventilation function to operate efficiently through the lateral inlet design.
4Adaptability or versatility
If multiple function modules are integrated on the bottom cover, then the versatility is improved, but the device complexity and difficulty of maintenance increase
Solution Approach 1:
Each function module (lighting, Bluetooth speaker, sensor, etc.) is segmented as a separate replaceable unit within the holder. This segmentation enables individual modules to be maintained, replaced, or upgraded independently, reducing overall device complexity for maintenance purposes.
Solution Approach 2:
The function module is designed with detachable connections to the holder, allowing dynamic reconfiguration and easy removal for maintenance. This dynamic design enables flexible maintenance strategies without requiring disassembly of the entire device.
