Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door signaling systems for transport vehicles, particularly those with curved leaves, suffer from mechanical deformation issues, inadequate light intensity, and complex installation, making them difficult to install and prone to damage, with insufficient visibility and ease of use.
Innovation Solution
A signaling assembly featuring a seal with a translucent lighting region and a separate lighting member fixed to the profile's wing, using light-emitting diodes, which directs light through a reflective interface to illuminate the seal's lighting region, ensuring mechanical integrity and high visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If light-emitting diodes are fixed directly to the exterior face of the door leaf, then the signaling function is achieved, but the information becomes invisible from the inside when the door is open and the structure requires significant modification
Solution Approach 1:
The light-emitting diodes are nested within a recess in the door leaf structure, allowing them to be positioned on the exterior face while remaining visible from the interior when the door is open. This nesting approach resolves the contradiction by providing both exterior mounting and interior visibility without requiring significant structural modification.
2Adaptability or versatility
If the support and diodes are curved to match the profile of a curved leaf, then the signaling assembly can be installed on curved surfaces, but the mechanical deformation is likely to damage the diodes by breaking at the level of their welding on the support
Solution Approach 1:
The support structure is divided into multiple segments that can be independently bent to match the curved profile of the door leaf. This segmentation allows the support to conform to curved surfaces without subjecting the diodes and their welds to excessive mechanical stress, thereby maintaining diode integrity while achieving adaptability to curved geometries.
3Device complexity
If the diodes are placed at the bottom of the profile housing, then the structure is simplified, but the opening delimited by the profile is very narrow which restricts access and makes installation complex and risky
Solution Approach 1:
The diodes are positioned in a recess that provides access from multiple directions, effectively adding a dimensional aspect to the installation approach. This recess structure allows installers to access the diodes from the front, side, or top depending on the specific door geometry, thereby simplifying installation while maintaining structural simplicity.
4Device complexity
If the lighting area is spaced from the diode by a significant distance and separated by the heel of the joint, then the structural design is simplified, but the light emitted is reflected and refracted resulting in insufficient visibility
Solution Approach 1:
A reflective surface is introduced as an intermediary element between the diodes and the lighting area. This reflective surface redirects and concentrates the light emitted by the diodes toward the lighting area, ensuring sufficient illumination intensity and visibility while maintaining the structural simplicity of having the lighting area spaced from the diodes.

AI summary
The invention relates to a signaling assembly comprising a joint (2), which comprises an attachment region (21) on the door leaf and an illumination region (20), and lighting means (4) capable of illuminating said illumination region of said joint, so as to emit at least one visual signal that is in particular representative of the state of opening and/or closing of the door. According to the invention, the lighting means is adapted to be fixed to a longitudinal region (11) of the leaf, so as to emit light in a direction substantially perpendicular (F1) to the longitudinal direction (X60) of said leaf, and this assembly further comprises means (3) for returning the light emitted by the lighting means, capable of directing said light in a direction substantially parallel (F2) to the longitudinal direction of the profile. The invention allows first to preserve the mechanical integrity of the lighting means when the latter is mounted on a curved leaf. It further allows to generate a light intensity in the region of the joint to be illuminated, which is much higher than in known solutions. It finally facilitates the mounting of the lighting means while ensuring maintenance of the lighting means which is particularly convenient.
