Modular Support Device for Public Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manufacturers of public transport vehicles face challenges in managing a variety of support devices for different passenger equipment, as existing support devices are specific to either seats or ischial supports, requiring multiple storage solutions.
Innovation Solution
A modular standard support device with adjustable crosspieces and uprights, allowing for the fixation of various passenger equipment configurations, including ischial supports, seats, and benches, enabling flexible adaptation to different equipment needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple specific support devices are designed for different passenger equipment (seats, ischial supports), then the support device can be optimized for specific equipment, but the storage and management complexity increases
Solution Approach 1:
The support device is designed with a universal structure comprising vertical uprights, horizontal cross members, and adjustable crosspieces that can accommodate multiple types of passenger equipment including seats, ischial supports, and bicycle storage systems. This multi-functional design allows a single standardized support device to replace multiple specialized devices, thereby reducing storage and management complexity while maintaining adaptability to different equipment types
2Device complexity
If a standardized modular support device is used for various passenger equipment, then the storage and management is simplified, but the specific optimization for different equipment types is reduced
Solution Approach 1:
The support device is segmented into modular components including vertical uprights, horizontal cross members, and adjustable crosspieces that can be independently positioned and configured. This segmentation allows the standardized support device to be customized for different equipment types through simple adjustment of component positions, maintaining specific optimization capabilities while benefiting from standardized manufacturing and simplified storage
Solution Approach 2:
The support device incorporates adjustable and movable elements, particularly the crosspieces that can be repositioned along the cross members, allowing the structure to dynamically adapt to different equipment configurations. This dynamic adjustability enables a single standardized device to provide equipment-specific optimization without requiring multiple specialized designs
