Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plant growing lamps have a large size due to the placement of the power supply on the heat sink, leading to increased transportation costs and limited flexibility in adjusting luminous intensity, as well as low universality of heat sinks, requiring multiple molds and inventory for different capacities.
Innovation Solution
An LED lamp with a modular housing featuring a frame that can be customized to accommodate varying numbers of lamp modules, allowing for adjustable brightness and easy replacement of modules, with the power supply housed within the frame to reduce height and increase universality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the power supply is installed on the heat sink, then the electrical connection is simplified, but the height of the lamp increases and the size cannot be reduced
Solution Approach 1:
The lamp is divided into independent modular units, each containing a heat sink with integrated power supply and LED modules. This segmentation allows each module to be self-contained with standardized dimensions, preventing height increase while maintaining electrical connection simplicity.
Solution Approach 2:
The heat sink is designed as a universal platform that simultaneously serves multiple functions: heat dissipation, power supply mounting, and LED module support. This multi-functionality eliminates the need for separate mounting structures, maintaining compact height while simplifying electrical connections.
2Illumination intensity
If heat sinks with different sizes are designed for different capacities, then the luminous intensity can be adjusted, but multiple molds are required and inventory complexity increases
Solution Approach 1:
The system uses a standardized heat sink platform with dynamically adjustable LED module configurations. Different luminous intensities are achieved by varying the number and arrangement of LED modules on the same heat sink platform, rather than creating different heat sink sizes, thus requiring only one mold.
Solution Approach 2:
The luminous intensity is adjusted by changing the quantity and configuration parameters of LED modules on a fixed heat sink platform, rather than changing the physical dimensions of the heat sink itself. This parameter-based adjustment maintains manufacturing simplicity while achieving variable luminous output.
3Device complexity
If the lamp size is determined during initial design, then the structure is fixed, but the ability to flexibly increase LED beads and adjust brightness is lost
Solution Approach 1:
The lamp structure is segmented into a fixed standardized platform and variable LED module components. This allows the base structure to remain simple and standardized while enabling flexible addition or removal of LED modules to adjust brightness, maintaining both structural simplicity and adaptability.
4Device complexity
If conventional lamp design is used, then the structure is simple, but the transportation cost increases due to large size
Solution Approach 1:
The lamp is segmented into compact modular units with standardized dimensions optimized for transportation efficiency. Each module contains integrated components (heat sink, power supply, LED modules) that eliminate unnecessary space, maintaining structural simplicity while reducing overall size and transportation costs.
