Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat climate control systems face challenges in minimizing manufacturing costs and reducing vibrations caused by commercially available fans, while ensuring efficient air distribution and easy installation.
Innovation Solution
A seat frame configuration that supports a radial fan with an axial inlet and radial outlet, using a dimensionally rigid holder with a frame-shaped receptacle and locking elements, allowing for easy integration of commercially available fans and flexible air guide channels for efficient air distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If commercially available fans are used in climate control systems, then manufacturing costs are reduced, but vibrations are generated that affect seat comfort
Solution Approach 1:
The patent introduces a holder as an intermediary component between the fan and the seat frame. This holder absorbs and isolates the vibrations generated by the fan, preventing them from being transmitted to the seat structure. The holder serves as a mediator that allows the use of inexpensive commercial fans while protecting against their harmful vibrational effects.
2Ease of operation
If a dimensionally rigid holder with locking elements is used to support the fan, then installation ease is improved, but device complexity increases
Solution Approach 1:
The holder is designed as a separate, modular component with integrated locking elements, dividing the mounting function from the fan itself. This segmentation allows the holder to be manufactured independently and installed as a single piece, simplifying the overall assembly process while providing stable fan support without requiring complex integrated solutions.
3Adaptability or versatility
If a universal fan configuration is used, then adaptability across different seat models is improved, but manufacturing precision requirements increase
Solution Approach 1:
The holder is designed as a universal mounting component that can accommodate various fan types and sizes through its frame-shaped receptacle. This universal design allows the same holder structure to be used across different seat models and fan configurations, providing adaptability while the standardized manufacturing of the holder itself maintains reasonable precision requirements.

AI summary
A seat frame for a vehicle seat comprises an upholstered seat cushion, a seat frame, an upholstery support structure attached thereto and a fan housing with a radial fan. The fan housing has an axial inlet and a radial outlet for the passage of air. The fan housing is supported in the seat frame by means of a holder which includes at least one frame-shaped receptacle adapted to receive the radial outlet of the fan housing and at least one locking element for connecting itself to the fan housing.
