Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional damping members for land vehicle seats are inadequate in providing improved shock absorption against external impacts, such as those from explosive materials, and fail to effectively protect occupants.
Innovation Solution
A damping member with two attachment points and fastening elements, such as tubes, that utilize a plug-connectable tube system for quick exchangeability, combined with shock absorbers that can absorb forces through deformation work, including a compressible or elastic substance and a housing designed for deformation, such as heart or cloverleaf shapes, or a multilayered strap with parallel seams for additional damping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional damping members are used, then the structure is simple, but the shock absorption capability against external impacts is inadequate
Solution Approach 1:
The damping member is divided into multiple functional segments: a housing with deformation capability, a shock absorber element, and a second shock absorber element. Each segment performs a specific damping function, allowing the system to handle different aspects of shock absorption independently while working together to provide enhanced overall protection against external impacts.
Solution Approach 2:
The damping member employs composite structural design combining a deformable housing (which can be made of metal or composite materials) with shock absorber elements (such as viscoelastic materials, foam, or hydraulic elements). This composite approach allows the system to leverage the advantages of different materials - the structural integrity of the housing and the energy-absorbing properties of the shock absorbers - to achieve superior shock absorption capability.
2Strength
If the housing is designed for deformation (heart or cloverleaf shapes), then deformation work is optimized for shock absorption, but manufacturing precision requirements increase
Solution Approach 1:
The housing is designed with curved geometries such as heart or cloverleaf shapes instead of straight angular forms. These curved shapes are inherently more suitable for deformation under impact loads, as they distribute stress more evenly and facilitate controlled deformation. The curvature allows the housing to absorb energy through elastic and plastic deformation while maintaining structural integrity, optimizing the deformation work capability for shock absorption applications.
3Adaptability or versatility
If fastening elements with plug-connectable tubes are used, then exchangeability is improved, but assembly complexity increases
Solution Approach 1:
The fastening elements are designed as universal plug-connectable tubes that can be used with various damping member configurations and seat types. The standardized tube design allows for quick exchangeability and adaptability across different applications, while the modular nature of the connection system actually simplifies overall assembly by providing a consistent, repeatable joining method rather than requiring custom fabrication for each installation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The proposed damping member significantly enhances shock absorption by distributing and reducing the impact energy through cooperative action of multiple shock absorbers, ensuring effective protection against external forces without impeding normal loading conditions.
Implementation Method 1
A shock absorber of this kind can be a compressible substance or an elastic substance that returns to its initial position after action of force
Implementation Method 2
an elastic substance that returns to its initial position after action of force
Implementation Method 3
The second shock absorber absorbs the exerted forces by deformation work. This means that the second shock absorber is deformed during the action of force. However, a deformation of this kind does not occur in the event of conventional loading and/or action of force on the damping member
Implementation Method 4
A shock absorber of this kind can be a compressible substance
