Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing design of refrigeration appliances requires complex and costly modifications to the partition molds to accommodate different fan models and installation orientations, leading to increased manufacturing costs and inefficiencies.
Innovation Solution
A refrigeration device with a modular fan support system that allows the fan to be easily adapted to various shapes and orientations, using a carrier that can be used with multiple fan models and fan covers, ensuring correct installation and airflow direction without modifying the fan cover or support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fan is pre-mounted in the partition wall with contours to define installation orientation, then the fan installation is secure and oriented correctly, but the partition wall shape becomes complicated and manufacturing costs increase
Solution Approach 1:
The invention separates the fan mounting function from the partition wall structure by introducing a dedicated mounting bracket. The bracket is attached to the partition wall and provides the necessary contours and attachment points for the fan, while the partition wall itself maintains its simple, streamlined shape for easy manufacturing.
Solution Approach 2:
The mounting bracket acts as an intermediary element between the partition wall and the fan. It translates the simple geometric surface of the partition wall into a secure mounting structure with appropriate contours, holes, and attachment mechanisms for the fan, without complicating the partition wall design.
2Adaptability or versatility
If the partition wall contours are adjusted to accommodate different fan models, then different fan models can be installed, but significant costs are incurred for each tooling adjustment
Solution Approach 1:
The mounting bracket is designed as a universal component that can accommodate multiple fan models and configurations. By adjusting the bracket rather than the partition wall molds, the system achieves versatility in supporting different fan types without incurring significant tooling adjustment costs.
Solution Approach 2:
The invention allows for parameter changes in fan mounting by modifying the bracket configuration (such as hole positions, contour shapes, or attachment mechanisms) while keeping the partition wall manufacturing parameters constant. This separates the adaptability requirement from the mold tooling requirements.
3Reliability
If the fan cover has contours specifically designed for attaching the fan, then the fan attachment is secure, but the fan cover shape becomes complicated and costs increase when manufacturing different models
Solution Approach 1:
The invention extracts the fan attachment function from the fan cover design and relocates it to a dedicated mounting bracket. The fan cover can maintain a simple, aerodynamic shape without complex contours, while the bracket provides the necessary attachment features for securing the fan.

AI summary
The invention relates to a refrigeration device, in particular a domestic refrigeration device, comprising a housing which surrounds at least one inner chamber containing a ventilator (1) and a ventilator cover (27; 34; 42) subdividing the inner chamber. Said ventilator (1) is mounted in the inner chamber by means of a support (2) which is embodied as a separate component from the ventilator covering (27; 34; 42). Said ventilator (1) can be inserted into the ventilator compartment (11) of the support in two different positions.
