Solution Overview

Problem

Connecting elongated luminaire assemblies is challenging due to their length and weight, requiring multiple people and external aids, leading to errors and time-consuming alignment.

Innovation Solution

A system with a longitudinally extended connector and centering sections that align and secure mounting rails, allowing for a single-person connection process by reducing play between components through a staged centering and alignment mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual alignment methods are used to connect luminaire assemblies, then connection accuracy can be achieved, but the assembly process becomes time-consuming and requires multiple people

Engineering Contradiction:
Improvealignment accuracyVSAvoidassembly time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The connector incorporates centering sections with guide surfaces that perform preliminary alignment of the mounting rails before the final connection is made. This pre-alignment action eliminates the need for time-consuming manual adjustment during the assembly process, allowing single-person operation while maintaining high precision.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The centering sections act as an intermediary mechanism between the two luminaire assemblies during connection. The guide surfaces on these centering sections facilitate smooth, precise alignment of the mounting rails, enabling accurate connection without requiring multiple people or external alignment tools.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If manual alignment methods are used to connect luminaire assemblies, then connection accuracy can be achieved, but the process becomes complex requiring external aids

Engineering Contradiction:
Improvealignment accuracyVSAvoidalignment process complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The alignment function is merged into the connector itself through the integration of centering sections with guide surfaces. This eliminates the need for separate external alignment tools and aids, simplifying the overall device while maintaining high alignment accuracy for the mounting rails.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The centering sections serve as an intermediary mechanism that provides built-in alignment guidance. The guide surfaces on these centering sections facilitate precise alignment of the mounting rails during connection, eliminating the need for complex external alignment procedures.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If luminaire assemblies are connected without pre-centering, then the connection process is simpler, but play between components increases leading to connection errors

Engineering Contradiction:
Improveconnection simplicityVSAvoidconnection precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The centering sections perform preliminary centering of the mounting rails through their guide surfaces before the final connection is established. This pre-centering action reduces play between components and prevents connection errors, while the overall process remains simple enough for single-person operation.

Inventive Principle:
Principle #10Preliminary action
