Preassembled Cooling Air Flap Module Mounting Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting modules for cooling air flap modules in motor vehicle front panels are not compact or robust, and lack efficient air supply and preassembly capabilities.
Innovation Solution
A mounting module comprising a forward-mounted reinforcing frame, a closed mounting frame with bearings, and an actuating device for cooling air flaps, which forms a preassembled module with the front panel, allowing for pivotable mounting and efficient air flow guidance through laminar transverse ribs, and easy assembly/disassembly with snap-in joints and an external actuating motor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a preassembled module with reinforcing frame and mounting frame is formed, then compactness and robustness are improved, but device complexity increases
Solution Approach 1:
The cooling air flap system is divided into separate functional modules: the mounting frame with bearings, the reinforcing frame, the cooling air flaps with bearing journals, and the actuating device. This segmentation allows each component to be manufactured and assembled independently, then combined into a preassembled module that is both compact and robust while managing complexity through modular design.
Solution Approach 2:
Multiple components are merged into a unified preassembled module structure. The mounting frame is fixed in the reinforcing frame, which is then connected to the front panel as an integrated unit. This merging creates structural stability and compactness while the modular nature allows for systematic assembly procedures.
2Manufacturing precision
If cooling air flaps are pivotably mounted in a closed mounting frame with bearings, then air flow control precision is improved, but manufacturing complexity increases
Solution Approach 1:
The mounting frame incorporates specific local features for precise pivotable mounting: bearing holes positioned at predetermined locations and bearing journals on the cooling air flaps. These localized precision features enable accurate air flow control while the overall manufacturing process remains manageable through standardized component production.
3Ease of operation
If the module is preassembled with all components including actuating device, then ease of installation is improved, but device complexity increases
Solution Approach 1:
The mounting frame, reinforcing frame, cooling air flaps, and actuating device are preassembled into a complete module before installation in the vehicle. This preliminary assembly includes positioning the mounting frame in the reinforcing frame, attaching bearing journals to flaps, and installing the actuating device. The preassembled module can then be installed as a single unit, significantly easing the installation process while the complexity is managed through systematic preassembly procedures.

AI summary
The cooling air flap module has a closed mounting frame with bearings and an actuating device for the cooling air flaps, and the mounting frame of the module is arranged so as to be fixed in a forward-mounted reinforcing frame. The mounting frame with the reinforcing frame can be connected as a constructional unit to the front panel so as to form a construction module.
