Emergency Lighting Pictogram Orientation via Dual Mounting System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous emergency lighting units are not ideally suited for installation on horizontal ceiling surfaces as the pictogram label is not oriented for easy readability, which is a problem in both wall and ceiling installations.
Innovation Solution
The autonomous emergency lighting unit is designed with a base that can be mounted on both wall and ceiling surfaces, featuring a support element that allows the pictogram label to be mounted in two orientations, ensuring it remains readable and visible in all installations by using an intermediate mounting system with distinct receiving means for parallel and perpendicular orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pictogram label is mounted parallel to the diffuser plate for wall installation, then the label is clearly visible on vertical surfaces, but the label becomes difficult to read when installed on horizontal ceiling surfaces
Solution Approach 1:
The mounting system enables the pictogram label to dynamically adapt its orientation relative to the diffuser plate based on the installation surface. By providing two distinct receiving means (first for wall mounting, second for ceiling mounting) that accept the same intermediate mounting system, the label's orientation changes from parallel to perpendicular relative to the diffuser plate, ensuring optimal readability for each application.
Solution Approach 2:
The intermediate mounting system serves multiple functions by being compatible with both the first and second receiving means of the base. This universal component allows a single mounting mechanism to achieve two different label orientations, making the overall system adaptable to both wall and ceiling installations without requiring different mounting hardware for each application.
2Ease of manufacture
If a fixed mounting orientation is used for the pictogram label, then the installation process is simplified, but the unit cannot be properly installed on both wall and ceiling surfaces
Solution Approach 1:
The mounting system is segmented into distinct functional components: a base with two specialized receiving means, and a universal intermediate mounting system that can be received in either. This segmentation allows each component to be optimized for its specific function while maintaining overall system versatility, enabling simple assembly through standardized interfaces.
Solution Approach 2:
The intermediate mounting system acts as an intermediary between the base and the pictogram label. It mediates the connection by being received in either the first or second receiving means of the base, thereby enabling the same mounting mechanism to achieve different label orientations suitable for wall or ceiling installations without complicating the overall assembly process.

AI summary
The invention relates to a self-contained emergency lighting unit (1) comprising: - a housing (10) including a base (100) suitable for mounting on a mounting surface and a diffuser plate (150) for a light beam closing the front of the base, and, - a support element (30) for attaching a pictogram label (40) to the outside of the housing.According to the invention, it is provided that: - the block includes at least one intermediate mounting system (20), - the support element includes at least one fastening means for cooperating with said intermediate mounting system, and - the base includes, on the one hand, a first receiving means adapted to receive said intermediate mounting system so that it cooperates with the fastening means of the support element in order to maintain the pictogram label in a plane substantially parallel to the diffuser plate of the housing, and, on the other hand, a second receiving means, distinct from the first receiving means, adapted to receive said intermediate mounting system so that it cooperates with the fastening means of the support element in order to maintain the pictogram label in a plane substantially perpendicular to the diffuser plate of the housing.
