Flexible Profile Sealing for Light Strip Dust Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light line systems with elongate support arrangements are not adequately protected against dust and moisture, making them unsuitable for use in industrial environments where a higher level of protection is required.
Innovation Solution
A light line system with an elongate support arrangement featuring support rail elements open at the underside, utilizing a profile part made of flexible material to form a sealed receiving space for the lighting module component, which is held in place by contact areas on the carrier arrangement, ensuring effective sealing and protection against dust and moisture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the support arrangement uses open U-shaped support rail elements arranged in a row, then the system is simple to assemble and allows easy mounting of light inserts, but the receiving space offers no or very limited protection against dust or moisture
Solution Approach 1:
A profile part made of flexible material (such as rubber or plastic) is introduced to form a sealed receiving space within the open U-shaped support rail elements. This flexible profile part creates a protective enclosure that prevents dust and moisture ingress while maintaining the simple modular structure of the support rails.
Solution Approach 2:
The profile part is nested within the U-shaped support rail elements to form a receiving space. The profile part fits into the open structure of the support rails, creating a nested configuration where the flexible profile provides protection while the rigid support rails provide structural support and ease of assembly.
2Object-affected harmful factors
If the receiving space is tightly closed on all sides to protect against dust and moisture, then protection against harmful factors is improved, but the structure becomes more complex and less flexible
Solution Approach 1:
The profile part made of flexible material provides the sealing function with a single component rather than requiring multiple rigid sealing elements. The flexibility of the material allows it to conform to the support rail structure and provide effective sealing while maintaining a relatively simple overall structure.
Solution Approach 2:
The system combines rigid U-shaped support rail elements with a flexible profile part made of materials such as rubber or plastic. This composite structure leverages the advantages of both material types: the rigidity and structural stability of the support rails, and the flexibility and sealing capability of the profile part, achieving effective protection without excessive structural complexity.
3Stability of the object's composition
If the lighting module component is held on two opposite sides with profile part interposed, then the mounting stability is improved, but the device complexity increases
Solution Approach 1:
The flexible profile part is used to hold the lighting module component on two opposite sides, providing stable mounting through the flexibility and conformability of the material. The profile part can adapt to slight variations in positioning while maintaining secure holding, achieving stable mounting without requiring complex adjustment mechanisms.
Solution Approach 2:
The lighting module component is designed to be held by the profile part through its own geometric features or contact areas, allowing the component to be passively secured by the flexible profile without requiring additional active fastening or adjustment mechanisms. The profile part's flexibility allows it to self-adjust to provide stable holding.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides robust protection against dust and moisture, allowing for reliable operation in dusty or damp environments, with a simple assembly process and flexible design that compensates for temperature-related pressure changes, ensuring the lighting module components remain secure and protected.
Implementation Method 1
at least one of the profile parts (4, 5) is designed so flexibly that in the event of a temperature change-related pressure change in the receiving channel (6), the pressure change can be at least largely compensated for by a change in shape of the corresponding profile part (4, 5)

AI summary
A light strip system comprises an elongate carrier arrangement formed by mounting rail elements (1, 2) that are open towards the lower face, a profiled part (4) which consists at least partly of a flexible material and forms an accommodation space (6) formed in the carrier arrangement and extending in the longitudinal direction, and a lighting module component (8, 8') arranged in the accommodation space (6). In order to hold the lighting module component (8, 8') it is arranged so as to push against contact regions (11, 12, 11', 12') of the carrier arrangement, on two opposite sides, each time with the interposition of regions of the profiled part (4).
