Internal Ventilation Shield for Plant Protector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable plant protectors against frost damage suffer from mechanical failure, are prone to environmental debris fouling, difficult and expensive to manufacture, and not easily stackable, with exposed ventilation covers being susceptible to damage and misalignment.
Innovation Solution
A plant protector device with an internal ventilation shield and temperature-sensitive actuator, housed within the structure to prevent fouling and mechanical failure, featuring a snap-lock closure system and anchor legs for stability, allowing for controlled ventilation and easy stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ventilation cover is disposed on the exterior of the housing for easy access, then the device can provide ventilation function, but the cover is susceptible to mechanical failure, fouling from environmental debris, and damage during stacking and storage
Solution Approach 1:
The ventilation cover is nested within a recess in the housing rather than being disposed on the exterior. The cover fits into a recessed cavity, allowing it to be protected from environmental debris and mechanical damage while still enabling ventilation when actuated. This nesting arrangement eliminates the need for external exposure of the cover.
Solution Approach 2:
A shield member is introduced as an intermediary protective element. The shield member can be actuated to block or open the ventilation opening, serving as a mediator between the external environment and the internal ventilation mechanism. This intermediary structure protects the cover from direct exposure to debris and mechanical damage.
2Ease of operation
If the ventilation cover is exposed on the exterior for functional access, then the device can control airflow, but the design is relatively difficult and expensive to manufacture due to deep cavity design requirements
Solution Approach 1:
By nesting the ventilation cover within a recess rather than requiring a deep cavity design, the manufacturing complexity is reduced. The recess provides sufficient space for the cover to function while being more compatible with standard injection molding techniques, thereby reducing manufacturing difficulty and cost.
3Adaptability or versatility
If the ventilation cover is externally disposed for operational access, then the device can respond to temperature changes, but the design is prone to mechanical failure during stacking and storage
Solution Approach 1:
The ventilation cover is nested within the housing recess, which provides structural support and protection during stacking and storage. This nested arrangement eliminates the vulnerability of externally disposed covers to mechanical damage while maintaining the temperature-responsive functionality through the actuator mechanism.

Function Achieved in This Case
The solution significantly reduces mechanical failure, enhances durability, and ensures proper operation after storage, while being cost-effective and easily stackable, maintaining effective frost protection and ventilation.
Implementation Method 1
a ventilation shield and actuator, internal to the housing, configured for movement between a first position that permits air passage through the ventilation openings and a second position that substantially impedes air passage through the ventilation openings
