Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional lighting fixtures use separate supply areas connected by cabling, then electrical power can be supplied to both areas, but the assembly becomes complex and time-consuming

Engineering Contradiction:
Improveelectrical power supplyVSAvoidcabling complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the electrical connection function into the mechanical coupling interface. The connector integrates both mechanical support and electrical contact functions, eliminating the need for separate cabling systems. The contact sections are built into the connector body, which couples directly to the rail profile, thereby combining structural and electrical functions into a single integrated component.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connector acts as an intermediary element between the power supply area and the powered area. It provides both mechanical coupling and electrical contact through its contact sections that engage with conductor devices in the rail profile. This intermediary component simplifies the overall system by replacing complex cabling with a direct electrical coupling mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If conventional lighting fixtures require separate feeders for each area, then complete power coverage is achieved, but installation effort increases

Engineering Contradiction:
Improvepower coverageVSAvoidinstallation effort
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The connector is designed as a universal component that can be used in both power supply areas and powered areas. It performs multiple functions: mechanical coupling to the rail profile, electrical contact through integrated contact sections, and signal transmission. This multi-functionality eliminates the need for different types of feeders and simplifies installation procedures.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The electrical contacts are pre-integrated into the connector body during manufacturing. The contact sections are positioned and fixed within the connector housing before installation. This preliminary preparation of electrical connections eliminates the need for on-site cabling and complex electrical assembly during installation.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If connector units are integrated into the rail profile areas, then electrical coupling is simplified, but the connector design becomes more complex

Engineering Contradiction:
Improveelectrical couplingVSAvoidconnector design
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The connector is segmented into distinct functional components: a body portion that couples to the rail profile, contact sections that engage with conductor devices, and housing elements that provide structural support and insulation. This segmentation allows each component to be optimized independently while maintaining overall simplicity of the coupling operation.

Inventive Principle:
Principle #1Segmentation
