Modular Vehicle Element with Segmented Lower and Upper Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for public transport vehicles, such as double folding seats with wheelchair retention systems, require complex and costly structures when space partitioning elements are used instead, leading to increased complexity and expense.
Innovation Solution
A modular element comprising a single lower component that can be combined with various upper components, including a holding device for wheelchairs, double folding seats, or barriers, reducing structural complexity and cost by allowing the lower component to be fixed to the vehicle while the appropriate upper component is attached as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a double folding seat with wheelchair retention system is used, then wheelchair holding capability is provided, but structural complexity and cost increase when space partitioning elements are used instead
Solution Approach 1:
The modular element is divided into a lower component and an upper component that can be separately assembled and configured. The lower component contains the wheelchair holding device, while the upper component can be configured as either a double folding seat or a space partitioning element, allowing independent optimization of each segment's function.
Solution Approach 2:
The lower component is designed as a universal base that can support multiple types of upper components. The same lower component with wheelchair holding capability can be combined with either a double folding seat upper component or a space partitioning element upper component, eliminating the need for separate complex structures for each function.
2Area of stationary object
If space partitioning elements are used alone to provide wheelchair space, then more space is available for wheelchair driver, but structural complexity and costs increase greatly
Solution Approach 1:
The modular element merges the wheelchair holding function, seating function, and space partitioning function into a single integrated structure. By combining these functions in one modular unit, the patent avoids the need for separate independent structures, thereby reducing overall structural complexity while providing all required functions.
Solution Approach 2:
The modular element serves multiple functions simultaneously: it provides wheelchair holding capability through the lower component, creates space for the wheelchair driver through the upper component configuration, and offers structural support. This multi-functionality eliminates the need for separate complex structures for each purpose.
3Adaptability or versatility
If different structures are produced for each upper component requirement, then specific requirements are met, but manufacturing complexity and costs increase
Solution Approach 1:
The modular element is segmented into a standardized lower component and interchangeable upper components. The lower component is manufactured once as a universal base, while different upper components (double folding seat or space partitioning element) can be manufactured separately and assembled, simplifying the manufacturing process compared to producing entirely different structures for each configuration.
Solution Approach 2:
The lower component is designed as a universal platform that can accommodate different types of upper components. This universality allows the same lower component to be manufactured once and reused with different upper components, significantly reducing manufacturing complexity and costs compared to producing custom structures for each specific requirement.

AI summary
A module element for a vehicle, in particular a public transport vehicle such as a bus or train, comprises a lower component and an upper component connected to the lower component at an interface. The essentially identical lower component can be combined with different upper components.
