Solution Overview

Problem

Conventional aisle lamps require multiple units or larger lamps to achieve uniform and pleasant illumination, often resulting in a bulky design and inadequate dazzle control, especially when illuminating longer aisles with changing storage arrangements.

Innovation Solution

A lamp design featuring a compact construction with a carrier device and multiple lighting units mounted on a lateral wall, utilizing concavely curved reflector portions to enhance light distribution and reduce dazzle, while improving heat dissipation through cooling stacks and ribs, allowing for efficient illumination of larger areas with fewer units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If conventional lamps are used to illuminate longer aisles, then uniform illumination is achieved, but the lamp size and quantity increase resulting in bulky design

Engineering Contradiction:
Improveuniform illuminationVSAvoidlamp size
Core Design Contradiction:
Illumination intensityVSVolume of moving object

Solution Approach 1:

The reflector device features concavely curved reflector surfaces that are curved in at least two curvature directions. This multi-directional curvature enables the reflector to efficiently distribute light from LED modules positioned at its edges, achieving uniform illumination across larger areas while maintaining a compact lamp structure.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The reflector surfaces are curved in multiple directions (bi-directional or multi-directional curvature) rather than simple single-axis curves. This adds dimensional complexity to the light reflection pattern, enabling more uniform light distribution across the illuminated area without increasing lamp volume.

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

2Area of stationary object

If multiple lamps or larger lamps are used to uniformly illuminate longer aisles, then illumination coverage is improved, but the number of components and device complexity increase

Engineering Contradiction:
Improveilluminated surface areaVSAvoidnumber of lamps
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The reflector device is divided into multiple reflector portions, each with concave reflector surfaces curved in at least two curvature directions. LED modules are positioned at the edges of these reflector portions, with each module illuminating a specific region. This segmentation allows a single lamp to cover larger areas that would otherwise require multiple lamps.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple reflector portions with different curvature characteristics are merged into a single integrated reflector device. This combination enables the lamp to achieve uniform illumination across extended areas, replacing the need for multiple separate lamps while reducing overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Illumination intensity

If conventional reflector designs are used, then manufacturing is simple, but light distribution uniformity and dazzle control are inadequate

Engineering Contradiction:
Improvelight distribution uniformityVSAvoidreflector design
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The reflector surfaces are designed with concave curvature in at least two directions, creating a more complex geometric form than conventional flat or single-curved reflectors. This multi-directional curvature optimizes light reflection patterns to achieve uniform illumination and有效控制 glare, though it increases manufacturing complexity.

Inventive Principle:
Principle #14Spheroidality (Curvature)

4Power

If lighting units are arranged to provide high light output, then illumination intensity is improved, but heat generation increases requiring better heat management

Engineering Contradiction:
Improvelight outputVSAvoidheat dissipation
Core Design Contradiction:
PowerVSTemperature

Solution Approach 1:

The lighting device is segmented into multiple LED modules distributed at the edges of different reflector portions. This segmentation distributes heat generation across multiple discrete sources rather than concentrating it in a single location, improving overall heat management while maintaining high total light output.

Inventive Principle:
Principle #1Segmentation
