Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ventilation fans lack the ability to efficiently improve air convection and exhaust harmful contaminations in unventilated rooms, limiting their applicability.
Innovation Solution
A ventilation fan with an integrated lamp module that includes a housing, fan module, and lamp module, where the lamp module forms air inlets with the ceiling, allowing for improved air flow and reduced ceiling space usage through a combination of a fan casing, impeller, motor, and adjustable lamp cover contact portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional ventilation fans are used in unventilated rooms, then ventilation function is provided, but the applicability is limited due to lack of additional functions
Solution Approach 1:
The patent combines a ventilation fan and a lamp into a single integrated device. The housing contains both the fan module (with motor and impeller) and the lamp module (with light source and reflector), allowing the device to provide both ventilation and illumination functions simultaneously, thereby improving adaptability without proportionally increasing complexity
Solution Approach 2:
The integrated device serves multiple purposes: it functions as both a ventilation fan for air circulation and a lamp for illumination. This multi-functionality allows a single device to replace what would traditionally require two separate devices, enhancing versatility while managing device complexity
2Volume of moving object
If a lamp module is integrated into the ventilation fan, then space usage efficiency is enhanced, but the device structure becomes more complex
Solution Approach 1:
The lamp module is merged with the ventilation fan housing, with the lamp positioned inside the housing near the air inlet. This integration eliminates the need for separate ceiling installations for lighting and ventilation, optimizing space usage by combining two functions in one device
Solution Approach 2:
The lamp module is nested within the housing structure of the ventilation fan. The light source and reflector are positioned inside the housing cavity, utilizing the existing structural space rather than requiring additional external space, thereby optimizing volume efficiency
3Productivity
If the lamp module is disposed through the installation opening, then air inlet gaps are formed for improved air flow, but the installation precision requirements increase
Solution Approach 1:
The contact portions of the lamp cover are designed with specific local geometries that create gaps when pressed against the ceiling surface. These localized gap formations at the contact portions provide adequate air inlet areas without requiring high precision across the entire installation, as only specific regions need to maintain proper spacing

AI summary
A ventilation fan with lamp is used to be installed to a ceiling including an installation opening and comprises a housing, a fan module and a lamp module. The housing includes a first opening and a second opening, and the first opening is aligned with the installation opening. The fan module is disposed in the housing. The lamp module is fixed to the first opening by a plurality of elastic elements passing through the housing and includes a lamp cover, a base and a lens. The lamp cover includes a flange portion and a plurality of contact portions, the flange portion and the contact portions are disposed outside the installation opening of the ceiling. The lamp module is connected to the ceiling via the contact portions to make a gap between the lamp cover and the ceiling, and the gap serves as an air inlet of the ventilation fan.
