Solution Overview

Problem

Existing illuminated sign systems face challenges in providing effective and durable lighting in emergency situations, especially in dark environments without electric power, and they often fail to guide accurately or maintain even illumination and structural integrity.

Innovation Solution

A fixing strip for light-source bands that is partly transparent and/or photoconductive, incorporating a light-storing substance to extend illumination after power outage, and designed for versatile application with reflective surfaces and adjustable width for improved visibility and durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If a phosphorized surface is used to illuminate signs in dark conditions, then the sign can emit light after exposure to light, but the illumination is not sufficient for long enough in dark conditions because the light absorbed from sunlight or distant lighting is inadequate

Engineering Contradiction:
Improveduration of illumination in dark conditionsVSAvoidbrightness of phosphorized surface
Core Design Contradiction:
Duration of action of stationary objectVSIllumination intensity

Solution Approach 1:

The patent introduces a light guide as an intermediary component between the light source and the phosphorized surface. The light guide collects light from the light source and directs it to illuminate the phosphorized surface, enabling the surface to absorb sufficient light energy to emit adequate illumination for extended periods in dark conditions.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a light-source band is fabricated with an envelope surrounding it through extrusion, then an essentially waterproof structure is achieved, but the light-source band cannot be easily modified to different widths for various applications

Engineering Contradiction:
Improvewaterproof structureVSAvoidadaptability to different widths
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent segments the light-source band into separate components: the light source assembly and the envelope are designed as independent elements that can be configured in different width variations. This allows multiple width specifications to be produced while maintaining the waterproof envelope structure, providing versatility for different application requirements.

Inventive Principle:
Principle #1Segmentation

3Strength

If the fixing of a light-source band to a mounting surface is strengthened to meet durability requirements, then the structural integrity is improved, but the complexity of the fixing structure increases

Engineering Contradiction:
Improvedurability of fixingVSAvoidcomplexity of fixing structure
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent combines the fixing function with the envelope structure by integrating fixing elements directly into the envelope design. This merging approach provides strong, durable fixing to mounting surfaces while avoiding the need for separate, complex fixing mechanisms, thus maintaining structural integrity without increasing overall complexity.

Inventive Principle:
Principle #5Merging (Combining)
