Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light curing technologies face challenges in efficiently curing thin films on low-temperature substrates of varying widths, as they often require high processing temperatures that can damage the substrate and are not adaptable to different web widths.
Innovation Solution
A modular light curing apparatus featuring a concatenated lamp housing with parallel-aligned flash lamps and a conveyor system, allowing for adjustable power supply, pulse control, and synchronization with substrate speed, enabling uniform curing of thin films on flexible substrates of any width through rapid, high-intensity light pulses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional oven curing is used to cure thin films on low-temperature substrates, then the thin film can be cured, but the substrate temperature must be maintained below its working temperature limit, making the process inefficient and time-consuming
Solution Approach 1:
The invention segments the heating function by introducing a separate heating element that independently heats the thin film without heating the substrate. This allows the thin film to reach curing temperature while the substrate remains below its working temperature limit, resolving the contradiction between curing temperature and substrate temperature control
Solution Approach 2:
The invention uses an intermediary heating element positioned between the light source and the substrate to selectively heat the thin film. This intermediary component enables precise thermal control of the thin film while isolating the substrate from excessive heat, allowing rapid curing without substrate damage
2Adaptability or versatility
If a fixed-width lamp housing is used, then the curing apparatus can be simple in design, but it cannot accommodate substrates of varying widths
Solution Approach 1:
The invention implements a dynamically adjustable lamp housing with movable lamp modules that can be repositioned along the housing to accommodate different substrate widths. This dynamic adjustment capability allows the same apparatus to handle various substrate sizes without requiring multiple fixed-width housings, resolving the contradiction between adaptability and structural simplicity
Solution Approach 2:
The lamp housing is designed as a universal structure that can accommodate substrates of varying widths through adjustable lamp positioning. This multi-functional design allows a single housing to serve multiple width requirements, eliminating the need for multiple specialized housings and reducing overall system complexity
