Modular Vehicle Interior Bracket for Bonded Mount Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles with fiber-reinforced plastic bodies, directly bonded support brackets often fail due to vibrations and acceleration loads, requiring time-consuming and labor-intensive replacement processes.
Innovation Solution
A modular support bracket system comprising a base plate fixedly bonded to the vehicle structure and a separate add-on module with form-fit engagement devices, allowing for easy replacement of the add-on module without damaging the base plate, using materials like Polyetherimide and Polyamide for lightweight and durable construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If brackets are directly bonded to the vehicle structure, then the brackets are firmly fixed and can bear loads, but they cannot be easily replaced when damaged
Solution Approach 1:
The bracket is divided into two segments: a base plate that remains permanently bonded to the vehicle structure, and an add-on module that can be easily attached and detached. This segmentation allows the permanent fixation of the mounting interface while enabling easy replacement of the functional component.
Solution Approach 2:
The replaceable functional part (add-on module) is extracted from the original integrated bracket design. This extracted module can be removed and replaced without affecting the base plate that is bonded to the vehicle structure, thus solving the replacement difficulty problem.
2Stability of the object's composition
If brackets are directly bonded to the vehicle structure, then the brackets provide stable support, but replacement requires destroying the bond and reworking the surface which is time-consuming
Solution Approach 1:
By segmenting the bracket into a permanently bonded base plate and a removable add-on module, the stable support function is maintained through the bonded base plate while the replacement time is reduced by eliminating the need to destroy bonds or rework surfaces.
Solution Approach 2:
The base plate is pre-bonded to the vehicle structure during manufacturing or initial installation, preparing the mounting interface in advance. This preliminary action ensures stable support is already in place, and subsequent replacements only require attaching/detaching the add-on module without any surface preparation.
3Device complexity
If a single integrated bracket design is used, then the structure is simple, but it cannot be adapted to different requirements without modification
Solution Approach 1:
The bracket is segmented into a standardized base plate and interchangeable add-on modules. The base plate maintains structural simplicity with a consistent bonding interface, while different add-on modules provide adaptability to various functional requirements without modifying the base plate.
Solution Approach 2:
The base plate is designed as a universal mounting platform that can accommodate multiple types of add-on modules through standardized engagement devices. This universality allows a single base plate design to serve multiple functions by simply changing the add-on module.
