Adaptive Desiccant Nozzle Positioning for Insulating Glass Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for applying desiccant to spacer frame assemblies in insulating glass units lack precision in dispensing the right amount and location of desiccant based on the spacer frame's width, leading to inefficiencies in moisture vapor control and potential condensation issues.
Innovation Solution
A system that automatically selects and positions a desiccant nozzle based on the width of the spacer frame, ensuring controlled dispensing of desiccant material into the interior region, with the volume per unit length adjusted according to the moisture vapor transfer rate, using a combination of nozzle indexing, adjustment actuators, and a controller to manage the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual or fixed-method desiccant dispensing is used, then the process is simple, but the precision of desiccant application amount and location varies with spacer frame width
Solution Approach 1:
The patent implements an adjustable nozzle positioning system that dynamically changes the nozzle's horizontal and vertical positions based on the detected spacer frame width. The nozzle can be repositioned along the spacer frame's length and adjusted in height, allowing the dispensing system to adapt to different frame dimensions and maintain precise desiccant application across varying widths.
Solution Approach 2:
The system changes the dispensing parameters (nozzle position, height, and potentially flow rate) based on the detected spacer frame width. By sensing the frame width and automatically adjusting these parameters, the system ensures optimal desiccant application precision for each specific frame size without requiring manual reconfiguration.
2Reliability
If desiccant dispensing is not adjusted for spacer width, then the system is simple to operate, but moisture vapor control effectiveness decreases
Solution Approach 1:
The dispensing system automatically detects the spacer frame width and adjusts the nozzle positioning and dispensing parameters without requiring manual intervention. The system self-regulates to optimize desiccant application for different frame widths, ensuring reliable moisture vapor control while maintaining ease of operation through automated width-based adjustment.
Solution Approach 2:
The system incorporates a sensing mechanism that detects the spacer frame width and provides feedback to the control system. This feedback enables automatic adjustment of the nozzle position and dispensing parameters, ensuring that the desiccant application is optimized for the specific frame width being processed, thereby improving moisture vapor control reliability.
3Measurement precision
If multiple nozzles are used for different spacer widths, then desiccant application accuracy improves, but the device complexity increases
Solution Approach 1:
Instead of using multiple fixed nozzles for different spacer widths, the patent employs a single adjustable nozzle that can dynamically reposition itself along the spacer frame's length and adjust its height. This dynamic positioning system achieves the same level of precision as multiple fixed nozzles but with reduced system complexity and easier adaptability to different frame configurations.

AI summary
A method and apparatus for controlling dispensing of a desiccant material into an interior region of an elongated spacer frame member. The appropriate desiccant dispensing nozzle is automatically selected and/or the distance between the desiccant dispensing nozzle and the elongated spacer frame member is automatically determined based on a property of the spacer frame member, such as the width of the spacer frame member.
