Solution Overview

Problem

Existing light box systems face challenges in efficiently and flexibly mounting semiconductor light sources, particularly in terms of assembly complexity and positioning, due to the need for individual screwing, riveting, or gluing of light modules to the frame.

Innovation Solution

A system utilizing profile rails with a connecting element that allows for the easy insertion and secure positioning of lighting modules, featuring cable tie recesses for electrical management and flexible alignment, and screw holes for dual functionality as both a holder for light modules and a mounting rail, enabling simplified assembly and adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If light modules are individually screwed, riveted or glued to the frame, then secure mounting is achieved, but assembly complexity increases and positioning flexibility is reduced

Engineering Contradiction:
Improvemounting securityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The frame is segmented into multiple profile rails that can be independently assembled and positioned. Each profile rail serves as a modular unit that can be attached to the frame and then receive light modules, allowing the system to be assembled in stages rather than requiring all components to be fixed simultaneously, thus reducing overall assembly complexity while maintaining secure mounting

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Profile rails act as intermediary components between the frame and light modules. Instead of directly fastening light modules to the frame, the profile rails serve as intermediate mounting structures that simplify the attachment process and provide flexible positioning, reducing assembly complexity while ensuring reliable mounting through the rail-module interface

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If light modules are individually fastened to the frame, then secure positioning is achieved, but positioning flexibility is reduced

Engineering Contradiction:
Improvepositioning precisionVSAvoidpositioning flexibility
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The profile rail system enables dynamic repositioning of light modules along the rail length. Modules can be moved to different positions on the same rail without requiring complete disassembly, allowing the system to adapt to different lighting requirements while maintaining precise positioning through the rail's structured support and attachment mechanisms

Inventive Principle:
Principle #15Dynamics

3Productivity

If multiple light modules are used in a common profile rail, then assembly is simplified, but electrical connection management becomes more complex

Engineering Contradiction:
Improveassembly efficiencyVSAvoidelectrical connection complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The profile rail serves multiple functions simultaneously: it provides mechanical support for light modules, enables easy positioning and mounting, and incorporates cable tie recesses for electrical connection management. By integrating the cable management function directly into the structural component, the system handles multiple challenges with a single multi-functional element, improving assembly efficiency without adding separate complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)
