Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers with desiccant inserts face challenges in maintaining effective moisture absorption over time due to saturation of external surfaces, leading to decreased adsorption kinetics and potential damage to moisture-sensitive goods.
Innovation Solution
A container design featuring a plastic body with a permeable insert element and a desiccant chamber, where the insert's sidewall forms a double-layered structure with the container body, enhancing adsorption kinetics and vapor transmission rates, and utilizing desiccant polymers or membranes to improve desiccant capacity and prevent desiccant particle dusting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a desiccant insert is placed inside the container, then moisture absorption capacity is improved, but adsorption kinetics deteriorate over time due to surface saturation
Solution Approach 1:
The desiccant system is segmented into two functional zones: an outer desiccant insert that provides initial moisture absorption and a desiccant chamber at the bottom that serves as a reservoir. This segmentation allows the system to maintain high adsorption kinetics by directing moisture vapor directly to the chamber while the insert provides supplementary capacity.
Solution Approach 2:
The permeable bottom of the insert element acts as an intermediary structure that facilitates moisture vapor transport from the storage compartment to the desiccant chamber. This intermediary enables efficient moisture redirection while maintaining structural integrity and preventing direct contact between the insert and container base.
2Reliability
If the container includes a desiccant insert, then protection against moisture is improved, but time to remove humidity from goods increases due to diffusion distance
Solution Approach 1:
The desiccant chamber is pre-positioned at the bottom of the container, creating a ready-made moisture collection zone before moisture ingress occurs. This preliminary arrangement ensures that moisture vapor has a direct and short path to the desiccant material, minimizing the time required for humidity removal while maintaining reliable protection.
Solution Approach 2:
The design transitions from a single-layer horizontal desiccant arrangement to a vertical configuration with a bottom chamber. This dimensional change creates a gradient structure where moisture vapor naturally migrates downward due to convection and gravity, reducing diffusion distance and accelerating moisture removal time while maintaining protective reliability.
3Quantity of substance
If desiccant material is placed in the container, then desiccant capacity is improved, but particle dusting occurs
Solution Approach 1:
A retainer mesh or screen is installed at the opening of the desiccant chamber to act as a physical barrier. This thin film structure allows moisture vapor to pass through while preventing desiccant particles from becoming airborne and dusting onto the goods in the storage compartment, thus maintaining both high desiccant capacity and product cleanliness.
Solution Approach 2:
The retainer structure is locally positioned only at the chamber opening where particle escape is most likely to occur. This localized quality control measure provides dust prevention exactly where needed without interfering with the overall desiccant capacity or moisture absorption functionality of the system.

AI summary
A container for receiving moisture sensitive goods containing a container body and a cap. The container body has a base and a sidewall extending upwards from the base. An insert element inside the container body has a bottom and an insert sidewall, wherein the insert element is dimensioned to fit into the interior of the container body such that at least a portion of an outer circumferential surface of the insert sidewall is in abutting contact to the inner circumferential surface of the sidewall of the container body. The insert sidewall and the sidewall of the container body are designed to attach the insert element inside the container body.
