Flower Pot Sealing Mechanism for Root Rot Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flower pots fail to effectively control the water supply rate over a long period, leading to excessive water movement and difficulty in preventing root rot, due to lack of sealing between the outer and inner pot bodies and complex structures that are hard to implement in practice.
Innovation Solution
A flower pot design with a folding portion and an elastic sealing member between the outer and inner pot bodies, utilizing a nonwoven fabric for water supply based on capillary phenomenon, and adjustable threaded portions for precise sealing control, made from materials like polycyclohexane dimethylene terephthalate for improved hydrolysis resistance and transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a double-layered flower pot structure is used without a sealing portion, then the structure remains simple, but the water supply rate cannot be controlled and excessive water moves to the inner pot body
Solution Approach 1:
A sealing portion is introduced as an intermediary element between the outer and inner pot bodies. This sealing portion includes a sealing member that can be elastically deformed to contact the inner pot body, creating a seal that allows controlled water supply while maintaining structural simplicity
Solution Approach 2:
The sealing member's elastic deformation property is utilized to change the sealing parameter dynamically. By elastically deforming the sealing member, the contact state with the inner pot body changes, enabling control over water supply rate without complex mechanical structures
2Ease of manufacture
If no sealing portion is provided between outer and inner pot bodies, then manufacturing remains simple, but internal pressure of water supply portion cannot be adjusted
Solution Approach 1:
The sealing portion acts as an intermediary that provides pressure control functionality. The sealing member's elastic deformation capability allows it to adjust the internal pressure of the water supply portion by modifying the seal contact, achieving pressure control without complex pressure regulation mechanisms
3Reliability
If a complex structure with gouged wood block and plate spring is used, then water supply control is attempted, but the structure becomes complicated and difficult to implement in practice
Solution Approach 1:
The complex gouged wood block and plate spring mechanism is extracted and replaced with a simpler sealing member. The essential function of controlling water supply is retained through the sealing member's elastic deformation, while removing unnecessary structural complexity
Solution Approach 2:
Instead of using mechanical components like plate springs and gouged wood blocks, the invention utilizes the elastic deformation parameter of the sealing member to achieve water supply control. This parameter-based approach simplifies the structure while maintaining control functionality
4Ease of operation
If excessive water is supplied to the inner pot body, then the water supply chamber functions freely, but root rot cannot be prevented
Solution Approach 1:
The sealing portion serves as an intermediary control mechanism between the water supply chamber and inner pot body. It regulates water flow to prevent excessive water accumulation, thereby controlling the harmful effect of root rot while maintaining ease of water supply operation
Solution Approach 2:
The sealing member's elastic deformation property is used to dynamically adjust water supply parameters. By controlling the degree of elastic deformation and contact pressure, the system regulates water flow rate to prevent root rot while maintaining operational simplicity
