Elevator Car Lighting Integrated with Decorative Structural Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator car lighting arrangements lack enhanced structural, electrical, optical, and economical characteristics, making them difficult to produce, install, and maintain, while also failing to provide a pleasant and ergonomic illumination of the interior space, especially when exterior light is absent.
Innovation Solution
The elevator car features a vertically extending lighting element integrated with decorative control elements and structural panels, allowing for easy installation and protection of the lighting elements, using LEDs for efficient illumination and a design that tilts and folds metal sheets to create spaces for the lighting, enhancing both aesthetics and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional lighting arrangements are used in elevator cars, then the lighting can illuminate the interior space, but the structural, electrical, optical and economical characteristics are not enhanced, and installation and maintenance are difficult
Solution Approach 1:
The lighting element is integrated with the decorative side element to form a unified component. The housing of the lighting element is formed by the decorative side element itself, eliminating the need for separate mounting structures and simplifying installation while enhancing structural reliability through the protective enclosure.
Solution Approach 2:
The decorative side element serves multiple functions: it provides aesthetic decoration, structural support, and housing for the lighting element. This multi-functionality reduces the number of separate components needed, easing installation while maintaining robust structural and electrical characteristics.
2Illumination intensity
If lighting elements are exposed in the elevator car, then illumination is provided, but the lighting elements are vulnerable to damage by passengers or load
Solution Approach 1:
The decorative side element, which could be seen as an additional structural component, is utilized to provide protective housing for the lighting element. This converts the potential harm of having multiple components into the benefit of integrated protection, shielding the lighting element from damage while maintaining illumination functionality.
Solution Approach 2:
The housing formed by the decorative side element acts as an intermediary protective barrier between the lighting element and external hazards (passengers or load). This intermediary structure allows the lighting element to function while being protected from direct exposure to harmful factors.
3Volume of moving object
If decorative elements are positioned close to structural panels, then space is maximized, but no protection or mounting space for lighting elements is available
Solution Approach 1:
The decorative side element is tilted relative to the structural panel, creating a three-dimensional configuration rather than a flat arrangement. This angular positioning generates usable space between the decorative element and structural panel, providing mounting volume for lighting elements while minimizing the projection into the elevator's interior space.
Solution Approach 2:
The decorative side element is designed with a tilted configuration rather than a fixed parallel arrangement, dynamically utilizing the available space between the structural panel and interior. This dynamic spatial arrangement creates mounting opportunities for lighting elements without permanently reducing the elevator's interior volume.
4Illumination intensity
If complex lighting arrangements are installed, then illumination quality improves, but installation and maintenance become more difficult
Solution Approach 1:
The lighting element is merged with the decorative side element, combining illumination functionality with aesthetic decoration. This integration simplifies installation by reducing the number of separate components and connections required, while maintaining the ability to provide quality ergonomic illumination through the unified design.
