Solution Overview

Problem

Existing light line system covers lack the ability to modify optical properties effectively, limiting the flexibility in light emission adjustments and installation convenience, especially for long covers without joints.

Innovation Solution

A cover with a holding device for optically effective elements, allowing easy connection and modification of light emission properties, designed to be rolled up and feature a plate-shaped support area with elastic connection areas and retaining lips for secure mounting on a mounting rail, enabling flexible optical element arrangement and easy installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the cover is designed with fixed optical properties, then the structure is simple and manufacturing is easy, but the ability to modify light emission properties is limited

Engineering Contradiction:
Improveability to modify optical propertiesVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cover is divided into functionally distinct areas: a support area with fixed optical properties for structural stability, and connection areas with different elastic properties for mounting flexibility. This segmentation allows the optically effective element to be positioned precisely on the support area while enabling flexible installation through the connection areas, thus providing adaptability without requiring complete structural complexity throughout the entire cover.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different areas of the cover are assigned different material properties: the support area has specific optical characteristics for light emission, while the connection areas have different elastic properties for mounting. This local differentiation allows the cover to provide both stable optical performance and installation flexibility, resolving the contradiction between fixed optical properties and modifyability.

Inventive Principle:
Principle #3Local quality

2Area of stationary object

If the cover is made very long to cover extensive areas, then coverage is improved, but installation becomes more difficult and joints are required

Engineering Contradiction:
Improvecoverage areaVSAvoidinstallation ease
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The cover incorporates connection areas with different elastic properties that provide flexibility to the overall structure. This flexibility allows the cover to be bent and maneuvered during installation, enabling long covers to be installed without requiring joints, thus maintaining ease of operation while achieving extensive coverage.

Inventive Principle:
Principle #30Flexible shells and thin films

3Reliability

If the connection area uses the same material as the support area, then manufacturing is simpler, but the connection to mounting rail becomes less reliable

Engineering Contradiction:
Improveconnection reliabilityVSAvoidmanufacturing simplicity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The connection areas are made from material with different elastic properties than the support area, creating local quality differentiation. This allows the connection areas to provide reliable mounting functionality while the support area maintains its optical properties, achieving reliable connection without requiring complete redesign of the entire cover structure.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The cover design integrates multiple functions into a single component: the support area provides optical functionality, while the connection areas provide mounting functionality. This multi-functionality allows reliable connection to the mounting rail while maintaining manufacturing simplicity through integration, resolving the contradiction between reliability and manufacturing ease.

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