Solution Overview

Problem

Conventional line-type lighting systems experience light leakage due to arrangement gaps between fixed frames and diffusion plates caused by flatness inconsistencies and construction defects, leading to aesthetic issues and material supply disruptions.

Innovation Solution

A continuous construction method for a side mold-coupled line-type lighting system, where fixed frames with protruding locking portions and L-shaped or T-shaped side molds are used to compensate for vertical and horizontal clearances, preventing light leakage by coupling the diffusion plate and side molds with the fixed frames, and allowing for adjustable insertion depths and elastic coupling structures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional fixed frames with standard lengths are used for line-type lighting systems, then the construction process is simplified, but arrangement gaps and light leakage occur due to flatness inconsistencies and construction defects

Engineering Contradiction:
Improveconstruction process simplicityVSAvoidlight leakage prevention
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The fixed frame is divided into multiple segments with connection portions that can be elastically coupled together. This segmentation allows each segment to independently adapt to local flatness variations while maintaining overall structural integrity, preventing arrangement gaps and light leakage between frames

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection portion incorporates elastic elements that change their mechanical parameters (flexibility, absorption capacity) to compensate for construction clearances. The elastic coupling structure can dynamically adjust to vertical and horizontal clearances, maintaining consistent spacing and preventing light leakage

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the fixed frame size is increased to cover construction defects, then light leakage is reduced, but material supply and transportation become disrupted

Engineering Contradiction:
Improvelight leakage preventionVSAvoidmaterial supply efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

By dividing the fixed frame into standard-sized segments with elastic connection portions, the system maintains manageable dimensions for material supply while the cumulative effect of multiple segments covers construction defects. The connection portions compensate for clearances without requiring oversized individual frames

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The elastic connection portion serves multiple functions: it acts as a spacer to maintain distances, a compensator for construction clearances, and a flexible connector for assembly. This multi-functionality allows standard-sized segments to achieve the light leakage prevention效果 of larger frames without disrupting material supply

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

3Adaptability or versatility

If various sizes of fixed frames are produced to match different side wing requirements, then design flexibility is improved, but manufacturing complexity and material supply are disrupted

Engineering Contradiction:
Improvedesign flexibilityVSAvoidfixed frame size variety
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single standardized fixed frame design with elastic connection portions can accommodate various design requirements by adjusting the number of segments and connection configurations. The elastic connections provide the necessary flexibility for different side wing arrangements without requiring multiple frame sizes

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

Solution Approach 2:

The elastic connection portions provide dynamic adaptability, allowing the fixed frame system to adjust to different configurations and designs. This dynamic flexibility replaces the need for multiple static frame sizes, simplifying manufacturing while maintaining design versatility

Inventive Principle:
Principle #15Dynamics
