Modular Rail Profile Assembly to Prevent Inner Profile Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rail profiles for lighting systems are complex and costly to produce due to stringent geometric and dimensional tolerances, leading to difficulties in assembly and potential jamming during the insertion of inner profile components.
Innovation Solution
A modular rail profile design where the outer and inner profile components are manufactured separately and can be easily connected through a locking mechanism, allowing for loose insertion and subsequent locking along the longitudinal extent, reducing the need for precise tolerances and simplifying the assembly process.

1Ease of manufacture
If conventional pressing processes with specially designed tools are used to integrate conductors into rail profiles, then electrical conductors can be integrated into the external profiles, but the production process becomes more complex and costly
Solution Approach 1:
The rail profile is divided into separate components: an outer profile and an inner profile that can be manufactured independently. The inner profile contains the electrical conductors and is inserted into the outer profile, eliminating the need for complex pressing processes to integrate conductors into the external profile.
Solution Approach 2:
The inner profile with electrical conductors is pre-assembled as a separate component before being inserted into the outer profile. This preliminary assembly allows for simpler manufacturing of each component individually and avoids the need for complex integration processes during final assembly.
2Ease of operation
If inner profile components are inserted from one end face into an outer profile, then assembly can be performed, but error tolerance is low and small deviations in geometry and dimensions can lead to the inner profiles getting stuck during insertion
Solution Approach 1:
The inner profile is designed to be nested within the outer profile, with the inner profile's cross-section fitting within the hollow space of the outer profile. This nesting arrangement allows for loose insertion from the end face and accommodates larger geometric and dimensional tolerances without causing jamming.
Solution Approach 2:
The outer profile is designed with a hollow cross-section that can accommodate the inner profile with various geometries and dimensions. This universal design allows the outer profile to work with different inner profile variations without requiring precise tolerance control, facilitating easier assembly.
3Reliability
If strict requirements with regard to tolerances are imposed to prevent the inner component from jamming and sticking, then assembly reliability can be maintained, but production becomes more complex and costly
Solution Approach 1:
By segmenting the rail profile into separate outer and inner components that are manufactured independently, the design allows for loose fitting and insertion without requiring strict tolerance control. This segmentation maintains assembly reliability while simplifying the production process for each component.

AI summary
The invention relates to a rail profile (1) for a profile light or for a track lighting system. The rail profile has an outer base profile component (2) with an inner region (3) and at least one inner profile component (4; 4'). The outer base profile component and the inner profile component can be manufactured separately. Furthermore, the outer base profile component and the inner profile component are designed such that, for assembly of the rail profile, the inner profile component can be loosely inserted into the inner region and subsequently snapped into place with the outer base profile component along a longitudinal extension (5) of the outer base profile component to mechanically connect the outer base profile component and the inner profile component.
