Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiator fan modules in vehicles require additional metal mounting components for stable connections, which increase complexity and noise transmission due to vibrations.
Innovation Solution
A radiator fan module with an elastic assembly holder and spreading elements that create a radial gap between the unit holder and radiator shroud, reducing vibrations and noise transmission while allowing for cost-effective and space-saving installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional metal mounting components are used to provide stable connection, then connection stability is improved, but device complexity and noise transmission increase
Solution Approach 1:
The mounting component is merged with the radiator frame by directly integrating the mounting structure into the frame itself, eliminating the need for separate metal mounting components. The radiator frame serves dual functions as both a structural support and a mounting platform for the pump unit.
Solution Approach 2:
A vibration damping element is introduced as an intermediary between the pump unit and the radiator frame. This intermediary component absorbs vibrations and reduces noise transmission while maintaining stable connection, replacing the need for complex metal mounting components.
2Reliability
If additional metal mounting components are used to provide stable connection, then connection stability is improved, but noise transmission increases
Solution Approach 1:
A vibration damping element is introduced as an intermediary between the pump unit and the radiator frame. This intermediary component absorbs vibrations and reduces noise transmission while maintaining stable connection, replacing the need for complex metal mounting components.
Solution Approach 2:
The vibration damping element converts harmful vibrations and noise into beneficial energy absorption, transforming the harmful mechanical vibrations into heat energy that is dissipated, thereby reducing noise transmission while maintaining connection stability.
3Reliability
If traditional mounting methods are used, then connection stability is achieved, but installation space and cost increase
Solution Approach 1:
The mounting component is merged with the radiator frame by directly integrating the mounting structure into the frame itself, eliminating the need for separate metal mounting components. The radiator frame serves dual functions as both a structural support and a mounting platform for the pump unit.
