Solution Overview

Problem

Mounting rail systems used for accommodating electrical and electronic components, such as lights and IoT devices, often face issues with component overcrowding and functional collisions, particularly with light emission areas being obstructed by other components.

Innovation Solution

A mounting rail system with an elongated support profile rail and busbar that includes a tapping element with a contact section, allowing for flexible electrical connections via a provision element outside the coupling opening, which can be rotated for coupling with the busbar, and additional connection openings for further components, enabling easy and flexible integration of various electrical and electronic components without obstructing the light emission area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If electrical or electronic components are installed in mounting rail systems, then connection options are provided, but components extend into light emission areas and cause functional collisions

Engineering Contradiction:
Improveconnection optionsVSAvoidfunctional collisions
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The tapping element is divided into distinct functional sections: a contact section for electrical coupling with the busbar, and a provision element for external connections. This segmentation allows the electrical connection function to be separated from the spatial occupation in the light emission area, enabling components to be connected without extending into the light path.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The provision element is extracted and positioned outside the support profile rail through a separate opening, while the contact section remains inside for electrical coupling. This extraction removes the external connection interface from the light emission area, eliminating functional collisions while maintaining connection versatility.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If tapping elements are inserted via coupling opening, then electrical coupling is achieved, but the coupling opening is blocked and cannot be used for light emission components

Engineering Contradiction:
Improveelectrical couplingVSAvoidcomponent installation
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The support profile rail is provided with two distinct openings: a coupling opening for inserting tapping elements to achieve electrical coupling, and a separate provision opening for external connections. This segmentation allows both electrical coupling and component installation to occur through different access points, preventing mutual interference and maintaining both reliability and adaptability.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If components are installed to provide electrical connections, then power and data transfer are enabled, but light emission functionality is obstructed

Engineering Contradiction:
Improvepower and data transferVSAvoidlight emission
Core Design Contradiction:
Adaptability or versatilityVSIllumination intensity

Solution Approach 1:

The provision element is taken out and positioned externally through a separate opening, removing it from the light emission path. This allows power and data transfer functionality to be provided without any component parts obstructing the light emission area, maintaining both adaptability and illumination intensity.

Inventive Principle:
Principle #2Taking out (Extraction)
