Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The retrofitting and maintenance of platform facilities in public transport areas, such as low-floor vehicles and trams, are labor-intensive due to the complexity of integrating new equipment and utilities into existing infrastructure.
Innovation Solution
A modular platform installation device with U-shaped cross-section installation bodies and prefabricated platform slabs that form a trough-like structure, allowing for easy assembly and maintenance, with integrated cable routes and heating systems, and featuring sealing devices to prevent fluid leaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional platform installation methods are used, then platform structure is established, but retrofitting and maintenance of utilities and equipment becomes labor-intensive and complex
Solution Approach 1:
The platform installation device is divided into modular components including installation bodies with U-shaped cross-sections that form separate trough-like structures for utilities, and platform slabs that form the walking surface. This segmentation allows independent installation and maintenance of utility systems without disrupting the entire platform structure.
Solution Approach 2:
The installation bodies serve multiple functions: they provide structural support for platform slabs, create defined installation spaces for utilities (cables, pipes, heating systems), and enable future retrofitting of equipment. This multi-functionality reduces the need for separate structural elements and simplifies integration of new equipment.
2Adaptability or versatility
If utilities are integrated into existing platform infrastructure, then platform functionality is enhanced, but maintenance effort increases considerably
Solution Approach 1:
Utilities are extracted into separate trough-like structures formed by the U-shaped installation bodies, positioned beneath the platform slabs. This extraction creates dedicated access spaces for utilities, allowing maintenance personnel to reach and service cables, pipes, and heating systems without dismantling platform slabs or disturbing the overall platform structure.
Solution Approach 2:
The installation bodies are pre-configured with U-shaped cross-sections that define installation spaces for utilities before platform slabs are installed. This preliminary configuration ensures that utility access paths are established in advance, facilitating future maintenance activities without requiring complex demolition or reconstruction work.
3Productivity
If prefabricated modules are used for installation bodies and platform slabs, then assembly efficiency is improved, but manufacturing and assembly precision requirements increase
Solution Approach 1:
The system uses prefabricated modular installation bodies with standardized U-shaped cross-sections and matching platform slabs. These segments are designed with complementary geometry that guides precise alignment during assembly, reducing the impact of tolerance variations and simplifying the connection process while maintaining high assembly efficiency.
