Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems in public transport vehicles, such as buses, lack versatility in providing adequate lighting conditions due to variations in vehicle design, roof type, and door presence, leading to insufficient internal space illumination.
Innovation Solution
A ceiling assembly with a central plate and corner elements housing lighting assemblies, featuring a support portion with adjustable lighting means and a flexible cover with varying translucency, allowing for customizable lighting distribution through LED lights controlled by an electronic unit, ensuring optimal illumination with direct, indirect, and main lighting options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing lighting systems are used, then the structure is simple, but the lighting versatility and adaptability to different vehicle configurations is insufficient
Solution Approach 1:
The lighting means are made adjustable and movable within the ceiling assembly, allowing dynamic repositioning to adapt to different vehicle configurations (roof types, door positions, mission lengths). This enables a single system to provide optimal lighting for various scenarios without requiring multiple fixed lighting systems.
Solution Approach 2:
The ceiling assembly integrates multiple functions: housing lighting means, providing structural support, enabling cable access through hollow corner elements, and allowing maintenance access. This multi-functional design achieves lighting versatility without proportionally increasing system complexity.
2Adaptability or versatility
If lighting means are fixed in position, then the installation is simple, but the ability to provide optimal lighting for different vehicle configurations is limited
Solution Approach 1:
The lighting means are designed to be movable within the ceiling assembly rather than fixed, allowing them to be repositioned during installation and maintenance to optimize lighting for different vehicle configurations. This dynamic capability provides adaptability while maintaining reasonable installation simplicity through standardized mounting mechanisms.
3Ease of repair
If the ceiling assembly is designed with multiple access points, then the ease of maintenance improves, but the structural complexity increases
Solution Approach 1:
The ceiling assembly is segmented into modular components (central plate, corner elements, lighting assemblies) that can be independently accessed and maintained. The hollow corner elements serve as access points to the cable tray, allowing maintenance personnel to reach internal components without disassembling the entire ceiling structure.
Solution Approach 2:
The hollow corner elements act as intermediary structures that provide access to the cable tray and lighting components. These elements mediate between the external environment and the internal wiring/lighting systems, enabling maintenance access without requiring complex disassembly procedures.
