Solution Overview

Problem

Existing free-standing luminaires are large, require multiple people for assembly, have wire management issues, and lack flexibility in lighting adjustments, leading to aesthetic and functional limitations.

Innovation Solution

A modular luminaire design with a releasable connector and mounting system allowing single-person assembly, flexible head mounting, and integrated electrical components for easy maintenance and upgrade, featuring a connector body that extends horizontally from the pole to facilitate easy installation and adjustment of luminaire heads.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If free-standing luminaires are made large in size, then structural stability is improved, but assembly complexity increases and requires multiple people

Engineering Contradiction:
Improvestructural stabilityVSAvoidassembly complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The luminaire is divided into modular components including a base unit, connection unit, lamp unit, and fastening unit. Each module can be independently manufactured, shipped, and assembled. The connection unit specifically segments the electrical connection functions from the structural support functions, allowing separate optimization of each component.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The lamp unit is designed to be nested within or attached to the connection unit, which itself is attached to the base unit. The fastening unit provides nested securing mechanisms that allow components to be firmly attached while maintaining ease of assembly. This nesting approach consolidates multiple functions into hierarchical structures.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Shape

If luminaire head is made slim, then aesthetic appearance is improved, but wire management becomes difficult and may create wire traps

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidwire management
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

The connection unit serves as an intermediary component between the base unit and lamp unit, specifically housing the electrical connections and wire routing pathways. This mediator component provides dedicated wire management space and structured cable routing, preventing wire traps while maintaining the slim profile of the luminaire head.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of repair

If luminaire head is made detachable, then maintenance ability is improved, but structural stability may be reduced

Engineering Contradiction:
Improvemaintenance abilityVSAvoidstructural stability
Core Design Contradiction:
Ease of repairVSStability of the object's composition

Solution Approach 1:

The fastening unit is pre-configured with securing mechanisms such as bayonet mounts, screw connections, or snap-fit features that ensure stable attachment of the lamp unit to the connection unit. These preliminary mechanical arrangements provide structural stability equivalent to permanent fixtures while maintaining ease of detachment for maintenance purposes.

Inventive Principle:
Principle #10Preliminary action
