Solution Overview

Problem

Existing luminaire designs face challenges in accessibility and space efficiency, particularly in narrow and large constructions, with complex electrical components and maintenance difficulties due to fixed light sources and structures.

Innovation Solution

A luminaire design featuring a translucent disc with a light-emitting surface, a reflector for efficient light distribution, and a plug-and-swivel connection system for easy assembly and disassembly, along with a second light source for downward illumination, enhancing accessibility and space utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the luminaire uses a fixed light source arrangement with bonded lenses, then the light distribution can be controlled, but the accessibility to the interior space and maintenance become difficult

Engineering Contradiction:
ImproveAccessibility to interior spaceVSAvoidFixed light source structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The luminaire is divided into separable modules: the light guide element with light sources can be detached from the housing, allowing easy access to the interior space for maintenance while maintaining the integrated light distribution function during operation

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The light source arrangement transitions from a fixed bonded structure to a dynamic, removable configuration that allows the light guide element to be easily inserted and removed from the housing for maintenance purposes

Inventive Principle:
Principle #15Dynamics

2Volume of moving object

If the luminaire is designed with narrow and large construction, then the space utilization is improved, but the arrangement of electrical functional devices becomes constrained

Engineering Contradiction:
ImproveNarrow and large constructionVSAvoidArrangement of electrical components
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The luminaire adopts a vertical orientation with the light guide element extending in the vertical dimension, allowing the electrical functional devices to be arranged along the length of the light guide element rather than being constrained in a horizontal plane, thus accommodating components within the narrow profile

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Illumination intensity

If the luminaire uses multiple light sources for area illumination, then the lighting coverage is improved, but the maintenance and adjustment become more difficult

Engineering Contradiction:
ImproveArea illumination coverageVSAvoidMaintenance of light sources
Core Design Contradiction:
Illumination intensityVSEase of repair

Solution Approach 1:

Multiple light sources are integrated into a single removable light guide element module, allowing all light sources to be accessed and replaced as one unit rather than individually, thus maintaining area illumination coverage while simplifying maintenance procedures

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The light source system transitions from fixed individual sources to a dynamic modular unit that can be collectively removed and replaced, enabling easy maintenance of multiple light sources while preserving the distributed illumination pattern

Inventive Principle:
Principle #15Dynamics
