Adapter Frame Boarding Step for Multi-Vehicle Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing boarding systems for vehicles require costly and complex redesign to adapt to varying installation spaces and customer requirements, leading to high planning efforts and increased costs.
Innovation Solution
A modular boarding system comprising a vehicle-independent cassette frame and vehicle-dependent adapter frame, allowing the same step cassette to be adapted to different vehicles using interchangeable adapter frames, eliminating the need for costly redesign.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cassette frame is made with vehicle-specific size to fit different vehicles, then the boarding system can be adapted to various vehicles, but the manufacturing cost and planning effort increase significantly
Solution Approach 1:
The system is divided into two independent segments: a standardized cassette frame (step cassette) and vehicle-specific adapter frames. The adapter frame acts as an intermediary component that connects the universal cassette frame to different vehicle-mounted receptacles, eliminating the need to redesign the entire step cassette for each vehicle type.
Solution Approach 2:
The adapter frame serves as a mediator component between the standardized cassette frame and various vehicle-mounted receptacles. It absorbs the vehicle-specific adaptation requirements, allowing the main cassette frame to remain unchanged while still achieving compatibility with different vehicles.
2Adaptability or versatility
If new or replacement parts are designed for each vehicle type, then the step cassette can be perfectly adapted to each vehicle, but the device complexity and number of parts increase
Solution Approach 1:
The cassette frame is designed as a universal component that can be used across multiple vehicle types. The adapter frame provides the vehicle-specific customization, allowing one standardized cassette frame design to serve multiple functions across different vehicle applications.
3Adaptability or versatility
If the cassette frame size is reduced to fit smaller installation spaces, then the boarding system can accommodate more vehicle types, but the step cassette functionality is compromised
Solution Approach 1:
The system separates the functional step cassette from the dimensional adaptation task. The cassette frame maintains its optimal size for functionality, while the adapter frame handles the dimensional adaptation to fit different installation spaces, ensuring both functionality and adaptability are preserved.
