Solution Overview

Problem

Conventional lighting fixtures lack flexibility in designing lighting effects, have complex installation processes, and require separate components for power supply and control, which are not space-efficient and elegant.

Innovation Solution

A tubular lighting device with integrated control arrangement in the end section, allowing for simple, versatile, and space-saving mounting and power supply, where the end section serves as both a mounting and housing unit, enabling continuous and uniform light emission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional lighting fixtures use separate components for control and power supply, then the lighting effect can be controlled, but the installation becomes complex and space-consuming

Engineering Contradiction:
Improvemounting simplicityVSAvoidnumber of separate components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The control arrangement is integrated directly into the end section of the tubular lighting device, merging previously separate control and lighting components into a single unified structure. This eliminates the need for separate control housings and reduces the number of mounting steps, directly resolving the contradiction between mounting simplicity and device complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The end section is designed to serve multiple functions simultaneously: it provides structural support for mounting the lighting device, houses the control arrangement, and enables electrical connection. This multi-functionality reduces the overall component count and simplifies installation while maintaining full control capability

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

2Reliability

If separate housing is provided for control arrangement, then control functions are protected, but space requirements increase and mounting becomes more complex

Engineering Contradiction:
Improvecontrol arrangement protectionVSAvoidspace requirements
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The control arrangement is housed within the existing end section structure rather than requiring a separate control housing. This integration provides adequate protection for control components while utilizing the space already allocated for mounting and electrical connection, thereby reducing total space requirements without compromising reliability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The control arrangement is nested within the end section, with control components positioned inside the structural housing that already forms part of the lighting device assembly. This nesting approach provides protection while minimizing the external dimensions and space footprint of the overall device

Inventive Principle:
Principle #7Nested doll (Nesting)

3Adaptability or versatility

If multiple separate components are used for power supply and control, then functional requirements are met, but installation effort and space consumption increase

Engineering Contradiction:
Improvelighting effect controlVSAvoidinstallation time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The control arrangement and power supply connection points are integrated into the end section, allowing both control functionality and electrical connection to be established during a single mounting operation. This eliminates the need for separate installation steps for control components, directly reducing installation time while maintaining full adaptability for lighting effect control

Inventive Principle:
Principle #5Merging (Combining)
