Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices, particularly those worn on the human body or exposed to high humidity, face issues with moisture intrusion leading to device malfunction due to hygroscopic materials and lack of effective drying methods, which often require users to choose between drying and charging, and existing drying methods are inefficient or unreliable.
Innovation Solution
A drying chamber system with a rotary air valve, desiccant, and sensors that control airflow and humidity levels to ensure effective drying and charging, using a closed-loop system with precise moisture measurement and desiccant regeneration to maintain ultra-low humidity environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional drying methods are used for electronic devices, then moisture removal is achieved, but device charging cannot occur simultaneously and drying efficiency is low
Solution Approach 1:
The patent combines drying and charging functions into a single integrated system. The drying chamber houses both the desiccant-based moisture removal mechanism and the charging circuitry, allowing electronic devices to be dried and charged simultaneously without requiring separate processes or equipment.
Solution Approach 2:
The drying chamber system serves multiple functions: it removes moisture from devices using desiccant material, simultaneously charges electronic devices through integrated charging ports, and provides a controlled environment for both operations. This multi-functional design eliminates the need for separate drying and charging processes.
2Reliability
If desiccant material is used to absorb moisture, then drying effectiveness is improved, but desiccant saturation occurs requiring regeneration
Solution Approach 1:
The system implements periodic regeneration of the desiccant material through heating cycles. A heater periodically raises the temperature of the desiccant to drive off absorbed moisture, restoring its drying capacity. This periodic heating and cooling cycle allows the desiccant to be reused multiple times, extending its service life while maintaining drying effectiveness.
Solution Approach 2:
The system changes the temperature parameter of the desiccant material to control its moisture absorption and release characteristics. During normal operation, the desiccant is maintained at ambient temperature for optimal moisture absorption. During regeneration, the temperature is increased to facilitate moisture release, and then cooled to restore absorption capacity.
3Productivity
If heated air is used for drying, then moisture evaporation rate increases, but heat can damage sensitive electronic components
Solution Approach 1:
The system uses desiccant material as an intermediary substance for moisture removal instead of directly heating the electronic device. The desiccant absorbs moisture from the air and device surfaces through adsorption, eliminating the need for high-temperature air that could damage sensitive components. This indirect moisture removal method achieves effective drying without thermal exposure.
Solution Approach 2:
The system replaces the mechanical/thermal drying approach (heated air circulation) with a chemical/physical approach (desiccant adsorption). Instead of using heat to drive moisture evaporation, the system employs desiccant materials that chemically bind and trap moisture molecules, providing a gentler drying method suitable for heat-sensitive electronics.
4Measurement precision
If airtight sealing is implemented for drying chamber, then humidity control precision is improved, but device access and operation becomes difficult
Solution Approach 1:
The system provides charging ports and data access points on the exterior of the drying chamber housing, allowing users to connect charging cables and access device functions without opening the chamber. This preliminary arrangement of access points enables continuous charging and data transfer while the device remains sealed inside the drying environment.
Solution Approach 2:
The chamber housing acts as an intermediary barrier that maintains the airtight sealed environment while providing external access points for charging and data transfer. These exterior ports allow electrical and data connections to reach devices inside the chamber without compromising the seal, enabling both precise humidity control and convenient user operation.
