Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting strip systems face challenges in flexibility and safety during installation, maintenance, and repair, particularly due to the complex configuration required to prevent accidental contact with high-voltage electricity supply cables and issues with electromagnetic compatibility when cables and operating devices are not separated.
Innovation Solution
A lighting strip system with an I-shaped support arrangement featuring two separated receiving regions, one for electricity supply and signal transmission lines and the other for operating devices, along with removable side walls for easy access and modular design, allowing for flexible positioning and simplified maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electricity supply cables are arranged freely accessible in profile elements to maximize positioning flexibility, then lamp unit positioning flexibility is improved, but safety deteriorates due to risk of accidental contact with high-voltage cables
Solution Approach 1:
The support arrangement is divided into two separate receiving regions: one for electricity supply cables and another for operating devices. This segmentation physically isolates high-voltage cables from user-accessible areas, eliminating safety risks while preserving positioning flexibility through the modular I-shaped design.
Solution Approach 2:
The electricity supply cables are extracted from the general support structure and placed in a dedicated, separated receiving region. This extraction removes the harmful element (high-voltage cables) from the user interaction zone while maintaining the overall flexibility of the lighting strip system.
2Device complexity
If electricity supply cables and operating devices are arranged together to simplify structure, then device complexity is reduced, but electromagnetic compatibility deteriorates due to interference
Solution Approach 1:
The support arrangement is segmented into distinct receiving regions for electricity supply cables and operating devices. This spatial segmentation reduces electromagnetic interference by increasing distance between potential sources of interference while maintaining relatively simple overall structure through the unified I-shaped design.
3Reliability
If fixed contact-making modules are used at predefined positions to ensure electrical connection, then electrical connection reliability is improved, but positioning flexibility deteriorates
Solution Approach 1:
The system uses flexible insulated cable looms that can be routed along the support arrangement to various positions. These flexible cables maintain reliable electrical connections through contact-making modules while allowing lamp units to be positioned flexibly at desired locations rather than being constrained to fixed positions.
4Object-affected harmful factors
If complex profile elements are used to protect cables from accidental contact, then safety is improved, but device complexity increases
Solution Approach 1:
Instead of using complex protective profile elements, the system segments the support arrangement into separate receiving regions. This simpler approach provides safety through spatial separation rather than through complex protective structures, reducing device complexity while maintaining safety.

AI summary
In a lighting strip system having an elongate support arrangement for holding lamp units and lines for electricity supply and/or signal transmission, the support arrangement has an I-shaped profile in cross section, with two receiving regions, which run in the longitudinal direction of the support arrangement and are separated by a preferably vertically aligned partition, wherein the lines for electricity supply and/or signal transmission are arranged in one of the receiving regions and operational devices of the lamp units are arranged in the other receiving region.
