Damper Tube and Backpack Valve Layout for Tight Vehicle Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing damper devices with a damper tube and backpack valve arrangement face challenges in adapting to limited installation spaces in vehicles without modifying existing components, as they lack flexibility in spatial arrangement.
Innovation Solution
A connecting element, such as a module flange or module flange arrangement, is used to connect the damper tube and backpack housing, allowing for offset or perpendicular placement of passage openings along the main extension axis, enabling flexible spatial arrangement without affecting functionality and allowing for the use of pre-existing components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the damper tube and backpack housing are connected directly with aligned passage openings, then the structural design is simple, but the adaptability to various installation spaces is poor
Solution Approach 1:
A connecting element is introduced as an intermediary component between the damper tube and the backpack housing. This connecting element includes passage openings and connection surfaces that enable flexible spatial arrangement while maintaining functional connectivity, thus resolving the contradiction between adaptability and structural simplicity.
2Adaptability or versatility
If the passage openings are arranged offset from each other along the main extension axis, then the spatial adaptability is improved, but the connection complexity increases
Solution Approach 1:
The connecting element introduces additional spatial dimensions and orientations for passage opening arrangements. By allowing passage openings to be offset along the main extension axis and providing connection surfaces at various angles, the system achieves flexible spatial adaptation without proportionally increasing connection complexity.
3Adaptability or versatility
If existing damper tubes and backpack housings are modified to achieve flexible arrangement, then the spatial adaptability is improved, but the manufacturing cost and complexity increase
Solution Approach 1:
The system is segmented into three independent components: the damper tube, the backpack housing, and the connecting element. This segmentation allows the existing damper tubes and backpack housings to remain unchanged, while only the connecting element needs to be manufactured with specific features, thereby maintaining ease of manufacture for the main components while achieving spatial adaptability.

AI summary
A damper device may include a damper tube and a backpack valve arrangement. The damper tube comprises an outer wall with a first passage opening. The backpack valve arrangement may be arranged in a backpack housing, and the backpack housing may have a second passage opening. The first passage opening and the second passage opening may be connected via a first duct of a connecting element. The damper tube may have a main extension axis, and the first and second passage openings may be offset from one another in a direction of the main extension axis. In some cases the connecting element is non-integral with the damper tube, and the connecting element is non-integral with the backpack housing.
