Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat protection solutions for components in motor vehicles are space-intensive and inefficient in reducing thermal energy transfer, particularly in hybrid technology where components are close to hot sources, leading to potential overheating and durability issues due to inadequate material damping.
Innovation Solution
A holding device with an elastomer section that incorporates a heat protection shield, where the shield is directly attached to the elastomer section, reducing vibration and heat transfer by using a radially extending shielding section and a latching mechanism for secure attachment, allowing for space-saving and effective thermal insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If heat protection elements are attached to rigid components in the installation space, then heat protection is provided, but a lot of installation space is required
Solution Approach 1:
The patent introduces an elastomer section as an intermediary between the holding element and the heat protection element. This elastomer section serves as a mounting medium that transmits minimal vibration and allows compact positioning, enabling the heat protection element to be placed close to hot components without requiring extensive installation space
Solution Approach 2:
The patent changes the mounting parameters by transitioning from rigid mounting to elastomer-based mounting. This parameter change allows the heat protection element to be positioned much closer to hot components (reducing installation space) while the elastomer's damping properties maintain protective functionality
2Stability of the object's composition
If rigid mounting of the unit on the engine is used, then stable attachment is achieved, but excessive vibration loads are transmitted to the unit
Solution Approach 1:
The elastomer section acts as a mediator between the engine and the holding element. It provides stable attachment while simultaneously damping vibration loads, converting mechanical vibration energy into heat through internal friction, thus protecting the mounted unit from excessive vibration
Solution Approach 2:
The patent changes the material parameter of the mounting connection from rigid to elastomeric. This material parameter change fundamentally alters the vibration transmission characteristics, reducing peak vibration loads while maintaining attachment stability through the elastomer's elastic properties
3Area of stationary object
If components are positioned close to hot sources to save space, then installation space is reduced, but heat transfer to components increases
Solution Approach 1:
The heat protection element serves as a thermal intermediary between hot engine components and other sensitive components. It creates a thermal barrier that reduces heat transfer by convection and radiation, allowing components to be positioned close together without excessive heat exposure
Solution Approach 2:
The patent employs composite material strategy by combining the elastomer section with a heat protection element made of thermally insulating materials. This composite structure provides both vibration damping and thermal protection functions in a compact configuration
