Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional lighting apparatuses are used in closets, then basic illumination is provided, but flexibility and scalability are limited
Solution Approach 1:
The lighting apparatus is divided into modular components: a base plate with light source module, interchangeable end modules, and a light passing cover. This segmentation allows users to mix and match different end modules (wireless, dimerizable, color temperature adjustable) with a single base unit, providing flexibility without requiring complete system redesign for different configurations.
Solution Approach 2:
The base plate module serves multiple functions: it provides structural support, houses the light source array, enables wireless communication for control, and accepts various interchangeable end modules. This universal design allows a single base unit to support multiple lighting configurations and control modes, enhancing adaptability while reducing overall system complexity.
2Area of stationary object
If multiple lighting units are connected in series for scalable illumination, then coverage area increases, but power management complexity increases
Solution Approach 1:
Multiple lighting units are electrically connected in series, merging their power consumption requirements into a single power chain. The first end module of the first unit connects to the second end module, creating a daisy-chain configuration where power and control signals flow sequentially through all units, simplifying power distribution while enabling scalable coverage.
Solution Approach 2:
The end modules serve as intermediary connection points between base plate modules. Each end module contains electrical contacts and control circuitry that facilitate series connection, allowing power and control signals to be transmitted between units without requiring complex wiring harnesses or centralized power management.
3Ease of operation
If wireless transmission capabilities are integrated in every unit, then individual control is improved, but cost increases
Solution Approach 1:
Wireless transmission capabilities are localized to specific end modules rather than being embedded in every unit. The first end module of the first lighting apparatus contains the wireless communication hardware and processing logic, while other units receive control signals through the series connection. This localizes the expensive wireless functionality to a single unit, reducing overall system cost while maintaining individual control capability.
Solution Approach 2:
Instead of duplicating wireless transmission hardware in every lighting unit, the control architecture copies the wireless command from the first end module to all subsequent units through the series connection. The first unit receives wireless commands and redistributes them to other units, eliminating the need for redundant wireless hardware while maintaining synchronized control across all units.
4Adaptability or versatility
If interchangeable end modules are used for different functions, then adaptability improves, but manufacturing complexity increases
Solution Approach 1:
The end modules are designed as separate, interchangeable components with standardized connection interfaces. Each end module can be manufactured independently with specific functions (wireless, dimerizable, color temperature adjustable), allowing specialized production runs for each module type while maintaining a common base plate design. This segmentation simplifies manufacturing by enabling modular assembly and independent optimization of each component.

Implementation Method 1
Electroluminescence, an optical and electrical phenomenon, was discover 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 allows 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 plate, 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 plate is connected to the light passing cover forming a container space. The base plate has an elongated shape. The first end module and the second end module are attached at two opposite ends of the base pate 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.
