Detachable Stabilizer Bar for EV Space and Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The design of electric vehicles faces challenges in maximizing internal space utilization due to the separation of mounting positions for stabilizer bars and gearboxes, leading to inefficient use of space and deteriorated maintainability as components are often detached for maintenance.
Innovation Solution
A suspension module with a stabilizer bar system that includes attachable and detachable first and second side stabilizer bars, integrated with a PE module and fixing members, allowing for efficient space sharing and easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the stabilizer bar and gearbox are mounted in separate spaces in the suspension system, then each component can be independently positioned, but the internal space utilization of the vehicle deteriorates
Solution Approach 1:
The patent integrates the stabilizer bar and gearbox into a shared mounting space within the suspension system. The stabilizer bar is positioned to face one side of the suspension frame, while the gearbox is mounted in the same general area, allowing both components to occupy overlapping or adjacent spaces rather than requiring completely separate volumes. This merging of spatial requirements improves overall space utilization in the vehicle.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement by having the stabilizer bar face one side of the suspension frame while the gearbox is positioned in a different orientation within the same space. By arranging components in different dimensional orientations rather than separating them in a single dimension, the design achieves both independent positioning capability and improved space utilization.
2Ease of operation
If components that do not need replacement are detached when maintenance components are removed, then access to maintenance components is achieved, but maintainability deteriorates due to unnecessary disassembly
Solution Approach 1:
The patent divides the suspension system into modular segments with independent mounting arrangements. The stabilizer bar is positioned and mounted separately from other suspension components, allowing it to be accessed and maintained independently. This segmentation enables maintenance workers to reach and service specific components without requiring disassembly of the entire suspension assembly, thereby improving maintainability.
Solution Approach 2:
The patent extracts the stabilizer bar from the traditional integrated suspension assembly and positions it as a separately accessible component. By taking out the stabilizer bar and providing it with its own mounting space and access path, the design allows maintenance personnel to service this component independently without removing other non-maintenance components, thus improving ease of repair.
3Stability of the object's composition
If the stabilizer bar is fixed rigidly to the suspension frame, then structural stability is improved, but adaptability for maintenance and space optimization deteriorates
Solution Approach 1:
The patent employs a dynamic mounting approach for the stabilizer bar, allowing it to be positioned to face one side of the suspension frame with attachable and detachable connections. This dynamic configuration enables the stabilizer bar to maintain structural stability during operation while also allowing for easy removal and repositioning during maintenance or space optimization, thus achieving both stability and adaptability.
Solution Approach 2:
The patent creates a universal mounting arrangement for the stabilizer bar that serves multiple functions: it provides structural stability when mounted, allows independent access for maintenance, and enables space optimization by positioning the bar to face one side of the suspension frame. The same mounting structure achieves all these objectives simultaneously, demonstrating multi-functionality.
