Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle mounting structures for electronic devices in engine or motor rooms fail to effectively isolate vibrations and thermal management, leading to inefficient cable wiring and potential damage from impacts.
Innovation Solution
A vehicle mounting structure that fixes an electronic device to a drive train with a gap using a bracket and a vibration isolating bush, featuring a tubular structure with elastic members to absorb vibrations and protect against impacts by positioning the vibration isolating bushes between the brackets and the electronic device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the electronic device is fixed directly to the drive train, then the mounting structure is simple, but vibrations from the drive train are transmitted to the electronic device
Solution Approach 1:
The patent introduces a vibration isolating bush as an intermediary component between the bracket and the electronic device. This bush absorbs vibrations from the drive train before they reach the electronic device, effectively blocking the transmission path of harmful vibrations while maintaining the overall simplicity of the mounting structure.
Solution Approach 2:
The vibration isolating bush is pre-installed in the mounting structure to provide cushioning against vibrations before they can affect the electronic device. This proactive approach prevents vibration transmission rather than addressing it after the fact.
2Volume of moving object
If the electronic device is mounted close to the drive train, then the mounting structure is compact, but thermal isolation is reduced
Solution Approach 1:
The vibration isolating bush serves a dual function as both a vibration absorber and a thermal insulator. By positioning this intermediary component between the bracket and the electronic device, the patent creates a thermal barrier that isolates the electronic device from heat generated by the drive train, even when mounted in close proximity.
3Stability of the object's composition
If the electronic device is fixed rigidly to the bracket, then the mounting structure is stable, but impact protection is reduced
Solution Approach 1:
The vibration isolating bush is pre-positioned to provide impact cushioning between the bracket and the electronic device. When impacts occur during vehicle operation, this bush absorbs and dampens the shock forces, protecting the electronic device from damage while maintaining stable mounting through the bracket connection.
Solution Approach 2:
The vibration isolating bush changes its mechanical parameters (stiffness, damping characteristics) in response to different operating conditions. Under normal vibrations, it provides flexible isolation, while under impact conditions, it absorbs shock energy, thereby adapting to protect the electronic device while maintaining mounting stability.
