Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If fluorescent lamps are used in closet lighting, then illumination is provided, but mercury contamination and electromagnetic interference occur
Solution Approach 1:
The patent changes the fundamental lighting technology parameter from fluorescent to LED, eliminating mercury and electromagnetic ballasts while maintaining illumination functionality. The LED modules with driver circuits provide the same lighting function without the harmful substances and interference issues of fluorescent lamps.
2Illumination intensity
If fluorescent lamps are used in closets, then lighting is provided, but temperature sensitivity reduces efficacy
Solution Approach 1:
The patent changes the lighting technology parameter from fluorescent to LED, which has superior temperature tolerance. LED modules maintain their luminous efficacy across a wider temperature range compared to fluorescent lamps, making them suitable for closet environments with varying temperatures.
3Use of energy by moving object
If early LED designs are used, then energy efficiency is improved, but functionality is limited
Solution Approach 1:
The patent applies multi-functionality by integrating door sensors, automatic activation, and interchangeable LED modules into a single lighting system. The lighting apparatus not only provides illumination but also responds to user actions (door opening) and allows customization through interchangeable modules, greatly enhancing functionality while maintaining LED energy efficiency.
Solution Approach 2:
The patent introduces dynamic features including automatic activation via door sensors and interchangeable LED modules that can be swapped to change lighting characteristics. This transforms the static early LED design into a dynamic system that adapts to user needs and environmental conditions.
4Illumination intensity
If conventional closet lighting is used, then illumination is provided, but flexibility and convenience are reduced
Solution Approach 1:
The lighting system provides self-service through automatic activation triggered by door sensors. When the closet door is opened, the system automatically turns on the lights without requiring manual intervention, enhancing convenience and ease of operation while maintaining proper illumination.

Function Achieved in This Case
The solution provides flexible, energy-efficient, and customizable lighting with reduced environmental impact, addressing the limitations of traditional lighting technologies by enabling automatic activation, adjustable output, and easy maintenance, while minimizing mercury contamination and electromagnetic interference.
Implementation Method 1
Electroluminescence, an optical and electrical phenomenon, was discovered in 1907. Electroluminescence refers the process when a material emits light when a passage of an electric field or current occurs.
Implementation Method 2
The light passing cover is for allowing a light of the light source module to pass through.

AI summary
A lighting apparatus includes a light source module, a light passing cover, a base housing, a first end module and a second end module. The light source module includes a plurality of LED modules. These LED modules may have different types. Each type has a different optical parameter, like color temperature, color, light intensity, color rendering index. The light passing cover allows a light of the light source module to pass through. The base housing is connected to the light passing cover forming a container space. The base housing has an elongated shape. The first end module and the second end module are attached at two opposite ends of the base housing for sealing the container space. The first end module is selectively connected to another second end module of another lighting apparatus for routing electricity and a control signal.
