Solution Overview

Problem

Existing lighting appliances for shop windows are not customizable, require separate installation, leading to longer installation times and complex procedures, and create an unpleasant dazzling effect due to the exposure of light profiles.

Innovation Solution

A lighting module with a containing profile bar that houses the lighting element and optical device, oriented to direct light inward without dazzling, and a modular design allowing quick assembly by integrating modules with dovetail-shaped cavities and a mounting plate.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If profile bars are used to contain the lighting element and optical device, then the lighting structure is stable and maintainable, but the light creates an unpleasant dazzling effect that distracts from displayed items

Engineering Contradiction:
Improvedazzling effectVSAvoidprofile bar structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The profile bar is designed with asymmetric geometry where the first side wall has a different configuration than the second side wall. The first side wall includes a first portion that is inclined relative to the transverse direction and divergent from the inside surface of the second side wall, while the second side wall has a second portion that is parallel to the transverse direction. This asymmetric design allows the light beam to be directed inward into the workspace while preventing it from exiting toward the viewer, thereby eliminating the dazzling effect without requiring complex additional components.

Inventive Principle:
Principle #4Asymmetry

2Ease of operation

If lighting appliances are installed separately with individual modules, then each module can be independently positioned, but installation time increases significantly and procedures become more complex

Engineering Contradiction:
Improveinstallation procedureVSAvoidinstallation time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The invention integrates the lighting element, optical device, and profile bar into a single pre-assembled module unit. The lighting element and optical device are housed within the profile bar structure, creating a unified component that can be installed as one unit rather than assembling multiple separate parts during installation. This merging of components significantly reduces installation time and simplifies the installation procedure while maintaining the ability to position modules independently along the longitudinal direction.

Inventive Principle:
Principle #5Merging (Combining)

3Illumination intensity

If the optical device is positioned flush with the side walls, then the profile bar has a compact appearance, but the light beam cannot be properly directed inward to illuminate the workspace

Engineering Contradiction:
Improveworkspace illuminationVSAvoidprofile bar appearance
Core Design Contradiction:
Illumination intensityVSShape

Solution Approach 1:

The optical device is positioned at an advanced position relative to the first and second side walls, extending beyond the transverse ends of the side walls. This positioning in the transverse dimension allows the optical device to receive the light beam from the lighting element and condition its direction effectively, directing the light beam inward into the workspace. The first side wall includes a first portion that is inclined and divergent, creating a housing space that accommodates the optical device at this advanced position, thereby achieving proper illumination without compromising the compact appearance of the profile bar.

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