Desiccant Cartridge With Elastic Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional desiccant cartridges waste space within the housing and require a spring to maintain desiccant pretension, leading to potential abrasion and increased air pressure requirements.
Innovation Solution
A desiccant cartridge design that uses elastic elements to fill the interior space partially, providing pretension to the desiccant without the need for a spring, allowing for efficient air drying and optional filtering of impurities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring is used to maintain desiccant pretension, then the desiccant is firmly fixed and cannot rub against one another, but the space between the cover plate and outer housing is wasted and not used for air drying
Solution Approach 1:
The patent combines the pretension function with the air drying function by using elastic elements that both apply pretension to the desiccant and occupy the previously wasted space for air drying, merging two functions into one component
Solution Approach 2:
The elastic elements serve multiple functions: they provide pretension to the desiccant to prevent abrasion, fills the void space in the housing, and create air permeable paths for air drying, making the component universal and multi-functional
2Object-affected harmful factors
If desiccant balls are compressed by a spring to prevent movement, then abrasion is suppressed, but air pressure requirements increase due to compression
Solution Approach 1:
The patent changes the physical state and arrangement of elastic elements to provide pretension with optimized force distribution, adjusting the parameters of the pretension system to reduce excessive compression while maintaining abrasion prevention
Solution Approach 2:
The elastic elements are distributed throughout the desiccant mass rather than concentrated in one location, providing local pretension that prevents abrasion without uniformly compressing all desiccant balls and increasing overall air pressure requirements
3Productivity
If the interior space is completely filled with desiccant, then air drying capacity is maximized, but the desiccant cannot be pretensed and will rub against one another
Solution Approach 1:
The patent creates a composite structure combining desiccant particles with elastic elements, where the elastic components provide mechanical stability and pretension while the desiccant maintains its air drying function, achieving both productivity and reliability
Solution Approach 2:
The elastic elements act as intermediaries between the housing and desiccant, providing the necessary pretension and structural support that allows the desiccant to remain stable without rubbing, while still permitting air flow for drying
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design optimizes space usage, reduces manufacturing costs, and prevents desiccant abrasion, maintaining efficient air drying performance without increasing air resistance or requiring retrofits.
Implementation Method 1
The elastic elements fill the released part of the interior space in such a way that the desiccant is located in the interior space under a pretension
Implementation Method 2
desiccant cartridges are used, with the desiccant cartridge optionally having filtering or cleaning to also remove protection and oil residues from the air

AI summary
A desiccant cartridge (100) for drying air comprises a housing (110) that forms an inner chamber (120), a desiccant (130) which incompletely fills the inner chamber (120), leaving part of the inner chamber (120) empty, and elastic elements (140) which fill the empty part of the inner chamber (120) in such a way that the desiccant (130) is prestressed in the inner chamber (120).
