Wall-Integrated Lens Arrangement Asymmetric Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall-integrated lighting devices for transportation installations, such as escalators and moving walks, lack adjustable positioning capabilities, leading to inefficient light direction and complex, time-consuming installation processes.
Innovation Solution
A wall-integrable lens arrangement with a complementary, non-central-symmetric attachment system that allows for pre-specified rotational positioning within a wall breakthrough, enabling precise light direction and simplified installation without additional tools or skills, using a lens arrangement with a flush lens head design for improved durability and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lens arrangement is inserted through the wall breakthrough without a pre-specified rotational positioning mechanism, then the installation process is simpler, but the light direction cannot be precisely controlled
Solution Approach 1:
The patent applies asymmetry by providing the lens arrangement with an asymmetric attachment member that has a specific rotational orientation relative to the optical axis. This asymmetric geometry engages with a corresponding asymmetric recess in the wall breakthrough, automatically positioning the lens at a predetermined rotation angle during installation. This resolves the contradiction by enabling precise light direction control through the asymmetric mechanical interface while maintaining installation simplicity, as the positioning occurs automatically during the insertion process without requiring additional alignment steps
2Ease of manufacture
If the lens arrangement is manufactured from numerous constructional components, then the device can be assembled with standard parts, but the assembly and installation become complicated and time-intensive
Solution Approach 1:
The patent applies merging by integrating the attachment member directly with the lens arrangement as a single unified component rather than as separate parts. The attachment member is formed as an integral part of the lens assembly, eliminating the need for separate mounting brackets, screws, or fastening mechanisms. This resolves the contradiction by simplifying the installation process and reducing assembly complexity while maintaining ease of manufacture, as the integrated design requires fewer manufacturing steps and eliminates the need for multiple component assemblies during installation

AI summary
A wall-integrable lens arrangement and a wall-integrated device with a connection housing and such a lens arrangement includes a connection housing having a radiation-emitting element. The connection housing is arranged on a first side of a wall and has an attachment portion and a connecting member. A lens arrangement has a lens head that is transparent to the radiation and an attachment portion and a connection member. The wall has a wall breakthrough through which at least one of the attachment portions projects, the connection members of the connection housing and the lens arrangement being mutually engaged. The wall breakthrough and at least one of the attachment portions that projects through it are complementary and formed in such a manner that the lens arrangement is maintained in a pre-specified horizontal position or rotational position and secured in the position against rotation.
