Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current plant growth lighting systems inadequately irradiate the back sides of leaves and stems, and top leaves block other leaves from effective photosynthesis, limiting the optimization of photosynthesis.
Innovation Solution
A three-dimensional (3D) plant growth lighting system comprising a top, lateral, and bottom lighting module, controlled by a controller that adjusts based on plant height, CO2 concentration, and light spectrum, using LED modules and a database of light formulas specific to plant species and growth stages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If lighting devices are arranged only above the plants, then the structure is simple, but the back sides of leaves and stems cannot be irradiated effectively
Solution Approach 1:
The patent transitions from a single-dimensional (top-only) lighting arrangement to a three-dimensional lighting system by adding lateral and bottom lighting modules. This dimensional expansion enables irradiation of previously inaccessible surfaces including back sides of leaves, stems, and lower leaves, directly resolving the contradiction between structural simplicity and comprehensive irradiation coverage.
2Device complexity
If lighting devices are arranged only above the plants, then the device complexity is low, but other leaves blocked by top leaves cannot effectively photosynthesize
Solution Approach 1:
By introducing lateral and bottom lighting modules, the system creates multi-directional light paths that penetrate through the plant canopy. This allows blocked leaves on lower branches to receive sufficient illumination for photosynthesis, thereby improving overall productivity without requiring a complete system redesign.
Solution Approach 2:
The patent applies lighting modules specifically at locations where light deficiency occurs - namely the lateral sides and bottom areas where leaves are blocked. This localized approach targets the problem areas without unnecessarily complicating the entire lighting system, balancing productivity improvement with device complexity.
3Illumination intensity
If a 3D lighting system with multiple modules is used, then all sides of plants can be irradiated, but the device complexity increases
Solution Approach 1:
The lighting system is divided into independent functional modules (top lighting module, lateral lighting module, and bottom lighting module). Each module can be independently installed, adjusted, and maintained. This segmentation reduces the complexity of managing a comprehensive 3D lighting system by breaking it down into manageable units that work together to achieve full irradiation coverage.

AI summary
A three-dimensional (3D) plant growth lighting system includes a top lighting module, a lateral lighting module and a bottom lighting module. The top lighting module is disposed on the top of a plant chamber and the plant chamber contains a plant. The lateral lighting module is disposed on one side of the plant chamber. The bottom lighting module is disposed on a bottom of the plant chamber. The controller is connected to the top lighting module, the lateral lighting module and the bottom lighting module so as to control the top lighting module, the lateral lighting module and the bottom lighting module.
