Ultraviolet Growth Direction Control for Ornamental Plants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for directing the growth of ornamental plants, such as using stakes or guides, are labor-intensive, prone to plant damage, and aesthetically undesirable, as they require manual application and may leave residues in the finished product.
Innovation Solution
The method involves using metered ultraviolet radiation with a wavelength less than or equal to 300 nm emitted by a light source, positioned to direct the growth of plant parts, reducing the need for physical supports and minimizing damage, allowing for controlled and efficient shaping of ornamental plants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual stakes or guides are used to direct plant growth, then the desired growth direction can be achieved, but the process becomes labor-intensive and time-consuming
Solution Approach 1:
The patent replaces the mechanical system of manual stakes and guides with an optical system using ultraviolet light sources. The UV radiation at specific wavelengths (200-300 nm) stimulates auxin production and redistribution in plant tissues, causing phototropic curvature that directs growth without any physical contact or mechanical support structures. This substitution eliminates manual labor while maintaining precise growth direction control.
Solution Approach 2:
The invention changes the physical-chemical parameters of the treatment by using specific ultraviolet wavelength ranges (200-300 nm, particularly 254 nm) and controlling exposure duration and intensity. By adjusting these parameters, the method achieves effective growth direction control with automated application, replacing the mechanical parameter-based approach of manual stake placement with optimized UV radiation dosing.
2Manufacturing precision
If manual stakes or guides are applied to plants, then growth direction can be controlled, but plant damage and breakage increase
Solution Approach 1:
The patent eliminates mechanical contact with plant tissues by replacing stakes and guides with non-contact ultraviolet radiation. The UV light sources are positioned to irradiate specific sides of plant stems and branches, inducing hormonal changes that cause the plant to grow in the desired direction without any physical force being applied to the plant structure, thereby preventing breakage and damage.
Solution Approach 2:
The invention introduces ultraviolet radiation as an intermediary between the operator and the plant. Instead of directly manipulating plant tissues with mechanical tools, the UV radiation serves as a mediator that triggers biochemical responses (auxin redistribution) within the plant, causing it to self-direct its growth. This indirect approach eliminates mechanical stress and damage to delicate plant structures.
3Manufacturing precision
If stakes or guides are used to support plant growth, then the desired form can be achieved, but residues remain in the finished product affecting aesthetics
Solution Approach 1:
The patent replaces the mechanical support system of stakes and guides with an optical field (ultraviolet radiation). Since no physical objects are introduced into the plant's growth environment, there are no foreign materials or residues left in the finished product. The UV-induced phototropic response achieves the desired form through the plant's own growth mechanisms, ensuring complete aesthetic quality without removal operations.
4Shape
If manual removal of stakes or guides is performed, then aesthetic quality improves, but additional time and labor are required
Solution Approach 1:
The invention extracts and eliminates the entire category of physical support structures (stakes, guides, and their removal operations) from the cultivation process. By using UV radiation to induce self-directed growth, the method removes the need for any foreign objects that would require subsequent removal, thereby eliminating the time and labor associated with the de-staking or guide-removal operations entirely.
Solution Approach 2:
The patent enables the plant to self-direct its own growth through UV-induced hormonal responses. The plant autonomously redistributes auxin in response to asymmetric UV irradiation, causing it to bend and grow toward the desired orientation without external mechanical assistance. This self-service mechanism eliminates the need for manual intervention at both the application and removal stages, saving significant time and labor.
