Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electromagnetic processing units for heating hollow plastic bodies face issues with moisture condensation, leading to electrical arcs and oxidation, and require frequent desiccant replacement and moisture monitoring, which are inefficient and pose safety risks.
Innovation Solution
The processing unit incorporates a dehydration circuit that extends outside the main body, using a closed-loop fluid circulation system with dehydrated pressurized fluid to maintain low moisture levels within the hollow housings, featuring fluid distribution and recycling circuits, and includes a moisture measurement device for safety and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a desiccation chamber with rechargeable desiccant is used to withdraw moisture from hollow housings, then moisture levels are reduced, but the device complexity increases and requires frequent maintenance
Solution Approach 1:
The patent extracts the desiccation function from a separate chamber and integrates it into the existing cooling circuit by dehydrating the cooling fluid as it circulates. This eliminates the need for a separate desiccation chamber and rechargeable desiccant, reducing device complexity while maintaining moisture control.
Solution Approach 2:
The cooling fluid circuit serves multiple functions: it cools the light emitting assembly and simultaneously dehydrates the hollow housing by circulating dehydrated cooling fluid through channels in the housing. This multi-functionality eliminates the need for separate moisture control systems.
2Object-affected harmful factors
If detectors and moisture monitoring systems are installed to check moisture ratio, then moisture control is improved, but the device complexity and cost increase
Solution Approach 1:
The cooling fluid circuit itself serves as the moisture control mechanism. The dehydrated cooling fluid naturally circulates through the housing channels, providing continuous passive moisture control without requiring active detectors or monitoring systems.
3Object-affected harmful factors
If through holes are provided for fluid communication between desiccation chamber and hollow housing, then moisture removal is enabled, but oxidation risk and electrical arc risk increase
Solution Approach 1:
The dehydrated cooling fluid acts as an intermediary medium that transfers moisture-removing properties from the cooling circuit to the hollow housing through sealed channels. This eliminates the need for direct through-holes that would expose internal components to oxidation and electrical arc risks.
4Ease of repair
If desiccant cartridges are made replaceable for maintenance, then ease of repair is improved, but device complexity and potential failure points increase
Solution Approach 1:
The patent extracts the desiccation function from replaceable cartridges and integrates it into the permanent cooling circuit system. This eliminates the need for cartridge replacement while reducing device complexity.
