Solution Overview
Problem
Current solutions for mounting dual rails on vehicles fail to absorb and manage forces, natural oscillations, and vibrations, which can transfer to components like charging ports and batteries, leading to potential damage.
Innovation Solution
A device comprising an elastic cushion with cavities for the dual rail and a mounting bracket with a recess and fastening mechanism, allowing for lateral insertion and compression of the rails, effectively absorbing forces and vibrations while keeping interfaces free from these stresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If plastic components with spring geometries are used to fasten the dual rail, then the rail is retained within the installation space, but the components cannot withstand the forces generated by the aluminum rail and transmit forces to connected interfaces
Solution Approach 1:
The patent changes the material parameter from plastic to elastic material with superior mechanical properties. The elastic material is specifically selected to withstand the high forces generated by aluminum rails while absorbing vibrations and thermal expansion forces, thereby protecting connected interfaces from force transmission.
Solution Approach 2:
The patent employs composite material structure combining elastic material with mounting brackets. This composite approach creates a mounting system that integrates both force absorption capabilities and structural support functions, enabling the system to handle high forces while maintaining reliability at interfaces.
2Stability of the object's composition
If the dual rail is fastened rigidly to the chassis, then the rail is securely positioned, but forces from linear expansion and vibrations are transmitted to connected components
Solution Approach 1:
The patent implements beforehand cushioning by using elastic material to preemptively absorb forces from linear expansion, vibrations, and thermal effects. This cushioning layer is positioned between the rail and mounting bracket, preventing harmful forces from reaching connected components while maintaining stable rail positioning.
Solution Approach 2:
The elastic material serves as an intermediary element between the dual rail and the mounting bracket. This mediator absorbs and dampens mechanical forces and vibrations, preventing their transmission to the chassis and connected components while maintaining the rail's stable position within the installation space.
3Strength
If the mounting device must accommodate thermal expansion and vibrations, then force absorption is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single integrated mounting device structure. The mounting bracket combines the functions of mechanical support, force absorption through elastic material, and vibration damping in one unified component, thereby achieving enhanced force absorption without proportionally increasing device complexity.
Solution Approach 2:
The patent employs flexible elastic material in the mounting device structure to accommodate thermal expansion and vibrations. This flexible element provides force absorption and vibration damping capabilities while maintaining a relatively simple overall device structure, avoiding excessive complexity.
